In this post, we see Software Testing Interview Questions. Our main focus is on questions asked in Real-World Based Manual Testing Interview Questions And Answers.
Before going ahead, let’s see some unavoidable Interview Questions such as Why did you choose Software Testing As Your Career . I don’t want to take much time of yours but I couldn’t move further without mentioning this inevitable question in an interview i.e., Tell Me About Yourself . Click on the link to get some ideas on how to answer general interview questions . So, Let’s move on to the actual post.

According to ANSI/IEEE 1059 standard – A process of analyzing a software item to detect the differences between existing and required conditions (i.e., defects) and to evaluate the features of the software item. Click here for more details.
SDET Vs Test Engineer Vs Developer
|Test Engineer thinks only in the terms of pass or fail of a test case and how to break the software||SDET knows system functional objectives as well as quality objectives||Developer thinks how to develop a system and make a functionality work|
|Test Engineer works only for test life cycle, like design of test cases, and execution||SDET is involved in Designing, development, and testing||Developer is limited to Coding part and release to testing team|
|No coding knowledge is required||Dynamic skill sets, like knowledge of quality and testing and good in coding too||Only coding knowledge is required|
|Test Engineers know where repetitive work or simple data entry is present but they are not expected to minimize the repetitive tasks||SDET understands automation needs, they can code and provide a solution to the team where repetitive kind of work is killing the time. They can design framework which can help testing team to reduce repetitive test cycle or simple data entry task.||Developers don’t deal with such tasks|
|Test Engineers are not expected to reach up to code level and tune the performance||Well aware of Performance tuning and security threats , they can suggest and reach to the code and suggest where application is poor in performance, plus they can optimize the code||Developers are only expected to code the functionality which is expected by customer|
Configuration management (CM) is a process of systems engineering to maintain system resources, computer systems, servers, software, and product’s performance in a consistent state. It helps to record all the changes made in the system and ensures that the system performs as expected even though changes are made over time.
Some of the popular configuration management tools are Ansible, Chef, Puppet, Terraform, Saltstack, etc.
If the software is so buggy, the first thing we need to do is to report the bugs and categories them based on Severity. If the bugs are critical bugs then it severely affects schedules and indicates deeper problems in the software development process. So you need to let the manager know about the bugs with proper documentation as evidence.
Quality Assurance: Quality Assurance involves in process-oriented activities. It ensures the prevention of defects in the process used to make Software Applications. So the defects don’t arise when the Software Application is being developed.
Quality Control: Quality Control involves in product-oriented activities. It executes the program or code to identify the defects in the Software Application.
Must read: Quality Assurance vs Quality Control
Verification is the process, to ensure that whether we are building the product right i.e., to verify the requirements which we have and to verify whether we are developing the product accordingly or not. Activities involved here are Inspections, Reviews, Walk-throughs. Click here for more details.
Validation is the process, whether we are building the right product i.e., to validate the product which we have developed is right or not. Activities involved in this is Testing the software application. Click here for more details.

Static Testing involves reviewing the documents to identify the defects in the early stages of SDLC. In static testing, we do code reviews, walkthroughs, peer reviews, and static analysis of a source code by using tools like StyleCop, ESLint, etc.,
Dynamic testing involves the execution of code. It validates the output with the expected outcome.
White Box Testing is also called as Glass Box, Clear Box, and Structural Testing. It is based on applications internal code structure. In white-box testing, an internal perspective of the system, as well as programming skills, are used to design test cases. This testing usually was done at the unit level. Click here for more details.
Various white-box testing techniques are:
Black Box Testing is a software testing method in which testers evaluate the functionality of the software under test without looking at the internal code structure. This can be applied to every level of software testing such as Unit, Integration, System and Acceptance Testing. Click here for more details.
Grey box is the combination of both White Box and Black Box Testing. The tester who works on this type of testing needs to have access to design documents. This helps to create better test cases in this process.
Positive Testing: It is to determine what system supposed to do. It helps to check whether the application is justifying the requirements or not.
Negative Testing: It is to determine what system not supposed to do. It helps to find the defects from the software.
Test Strategy is a high-level document (static document) and usually developed by the project manager. It is a document that captures the approach on how we go about testing the product and achieve the goals. It is normally derived from the Business Requirement Specification (BRS). Documents like Test Plan are prepared by keeping this document as a base. Click here for more details.
Test plan document is a document which contains the plan for all the testing activities to be done to deliver a quality product. Test Plan document is derived from the Product Description, SRS, or Use Case documents for all future activities of the project. It is usually prepared by the Test Lead or Test Manager.

Test Suite is a collection of test cases. The test cases which are intended to test an application.
Test Scenario gives the idea of what we have to test. Test Scenario is like a high-level test case.
Test cases are the set of positive and negative executable steps of a test scenario which has a set of pre-conditions, test data, expected result, post-conditions and actual results. Click here for more details.
Learn Difference Between Test Case vs Test Scenario
An environment configured for testing. Test bed consists of hardware, software, network configuration, an application under test, other related software.
Test Environment is the combination of hardware and software on which Test Team performs testing.
Test data is the data that is used by the testers to run the test cases. Whilst running the test cases, testers need to enter some input data. To do so, testers prepare test data. It can be prepared manually and also by using tools.
For example, To test a basic login functionality having a user id, password fields. We need to enter some data in the user id and password fields. So we need to collect some test data.
A test harness is the collection of software and test data configured to test a program unit by running it under varying conditions which involves monitoring the output with the expected output.
It contains the Test Execution Engine & Test Script Repository
Test Closure is the note prepared before test team formally completes the testing process. This note contains the total no. of test cases, total no. of test cases executed, total no. of defects found, total no. of defects fixed, total no. of bugs not fixed, total no of bugs rejected etc.,
Test Closure activities fall into four major groups.
Test Completion Check: To ensure all tests should be either run or deliberately skipped and all known defects should be either fixed, deferred for a future release or accepted as a permanent restriction.
Test Artifacts handover: Tests and test environments should be handed over to those responsible for maintenance testing. Known defects accepted or deferred should be documented and communicated to those who will use and support the use of the system.
Lessons learned: Analyzing lessons learned to determine changes needed for future releases and projects. In retrospective meetings, plans are established to ensure that good
practices can be repeated and poor practices are not repeated
Archiving results, logs, reports, and other documents and work products in the CMS (configuration management system).
Test coverage helps in measuring the amount of testing performed by a set of tests.
Test coverage can be done on both functional and non-functional activities. It assists testers to create tests that cover areas which are missing.
Code coverage is different from Test coverage. Code coverage is about unit testing practices that must target all areas of the code at least once. It is usually done by developers or unit testers.
Refer Test Metrics .

The most common components of a defect report format include the following
In software testing, there are four testing levels.
Unit Testing is also called Module Testing or Component Testing. It is done to check whether the individual unit or module of the source code is working properly. It is done by the developers in the developer’s environment. Learn more about Unit Testing in detail.
Integration Testing is the process of testing the interface between the two software units. Integration testing is done in three ways. Big Bang Approach, Top-Down Approach, Bottom-Up Approach. Learn more about Integration Testing in detail.
Click here for more details.
Testing the fully integrated application to evaluate the system’s compliance with its specified requirements is called System Testing AKA End to End testing. Verifying the completed system to ensure that the application works as intended or not.
Check this post Difference Between System Testing and Integration Testing
Combining all the modules once and verifying the functionality after completion of individual module testing.
Top-down and bottom-up are carried out by using dummy modules known as Stubs and Drivers. These Stubs and Drivers are used to stand in for missing components to simulate data communication between modules.
Testing takes place from top to bottom. High-level modules are tested first and then low-level modules and finally integrating the low-level modules to a high level to ensure the system is working as intended. Stubs are used as a temporary module if a module is not ready for integration testing.
It is a reciprocate of the Top-Down Approach. Testing takes place from bottom to up. Lowest level modules are tested first and then high-level modules and finally integrating the high-level modules to a low level to ensure the system is working as intended. Drivers are used as a temporary module for integration testing.
Integration Testing vs System Testing
|INTEGRATION TESTING||SYSTEM TESTING|
|It is a low level testing||It is a high level testing|
|It is followed by System Testing||It is followed by Acceptance Testing|
|It is performed after unit testing||It is performed after integration testing|
|Different types of integration testing are:
• Top bottom integration testing
• Bottom top integration testing
• Big bang integration testing
• Sandwich integration testing
|Different types of system testing are:
• Regression testing
• Sanity testing
• Usability testing
• Load testing
• Performance testing
• Maintenance testing
|Testers perform functional testing to validate the interaction of two modules||Testers perform both functional as well as non-functional testing to evaluate the functionality, usability, performance testing etc.,|
|Performed to test whether two different modules interact effectively with each other or not||Performed to test whether the product is performing as per user expectations and the required specifications|
|It can be performed by both testers and developers||It is performed by testers|
|Testing takes place on the interface of two individual modules||Testing takes place on complete software application|
In simple words, end-to-end testing is the process of testing software from start to end. Check this End-To-End Testing guide for more information. Also, refer System Testing tutorial.
In simple words, what the system actually does is functional testing. To verify that each function of the software application behaves as specified in the requirement document. Testing all the functionalities by providing appropriate input to verify whether the actual output is matching the expected output or not. It falls within the scope of black box testing and the testers need not concern about the source code of the application.
Learn more about Functional Testing here
In simple words, how well the system performs is non-functionality testing. Non-functional testing refers to various aspects of the software such as performance, load, stress, scalability, security, compatibility etc., Main focus is to improve the user experience on how fast the system responds to a request.
Functional Testing vs Non-functional testing
|Functional Testing||Non-functional Testing|
|What the system actually does is functional testing||How well the system performs is non-functionality testing|
|To ensure that your product meets customer and business requirements and doesn’t have any major bugs||To ensure that the product stands up to customer expectations|
|To verify the accuracy of the software against expected output||To verify the behavior of the software at various load conditions|
|It is performed before non-functional testing||It is performed after functional testing|
|Example of functional test case is to verify the login functionality||Example of non-functional test case is to check whether the homepage is loading in less than 2 seconds|
|Testing types are
• Unit testing
• Smoke testing
• User Acceptance
• Integration Testing
• Regression testing
|Testing types are
• Performance Testing
• Volume Testing
• Usability Testing
• Load Testing
• Stress Testing
• Compliance Testing
• Portability Testing
• Disaster Recover Testing
|It can be performed either manual or automated way||It can be performed efficiently if automated|
It is also known as pre-production testing. This is done by the end-users along with the testers to validate the functionality of the application. After successful acceptance testing. Formal testing conducted to determine whether an application is developed as per the requirement. It allows the customer to accept or reject the application. Types of acceptance testing are Alpha, Beta & Gamma.
The acceptance test plan is prepared using the following inputs.
All the above three inputs act as good inputs to prepare the acceptance test plan.
Alpha testing is done by the in-house developers (who developed the software) and testers before we ship the software to the customers. Sometimes alpha testing is done by the client or outsourcing team with the presence of developers or testers. It is a part of User Acceptance Testing . The purpose of doing this is to find bugs before the customers start using the software.
Beta testing is done by a limited number of end-users before delivery. It is done after the Alpha Testing. Usually, it is done in the client’s place. Learn more about Beta Testing here.
Gamma testing is done when the software is ready for release with specified requirements. It is done at the client place. It is done directly by skipping all the in-house testing activities.
Smoke Testing is done to make sure if the build we received from the development team is testable or not. It is also called as “Day 0” check. It is done at the “build level”. It helps not to waste the testing time to simply testing the whole application when the key features don’t work or the key bugs have not been fixed yet.
Sanity Testing is done during the release phase to check for the main functionalities of the application without going deeper. It is also called as a subset of Regression testing . It is done at the “release level”. At times due to release time constraints rigorous regression testing can’t be done to the build, sanity testing does that part by checking main functionalities.
Sanity vs Smoke Testing
|SMOKE TESTING||SANITY TESTING|
|Smoke Test is done to make sure if the build we received from the development team is testable or not||Sanity Test is done during the release phase to check for the main functionalities of the application without going deeper|
|Smoke Testing is performed by both Developers and Testers||Sanity Testing is performed by Testers alone|
|Smoke Testing exercises the entire application from end to end||Sanity Testing exercises only the particular component of the entire application|
|Smoke Testing, build may be either stable or unstable||Sanity Testing, build is relatively stable|
|It is done on initial builds.||It is done on stable builds.|
|It is a part of basic testing.||It is a part of regression testing.|
|Usually it is done every time there is a new build release.||It is planned when there is no enough time to do in-depth testing.|
To ensure that the defects which were found and posted in the earlier build were fixed or not in the current build. Say, Build 1.0 was released. Test team found some defects (Defect Id 1.0.1, 1.0.2) and posted. Build 1.1 was released, now testing the defects 1.0.1 and 1.0.2 in this build is retesting.
Complete Guide: Retesting
Repeated testing of an already tested program, after modification, to discover any defects introduced or uncovered as a result of the changes in the software being tested or in another related or unrelated software components.
Usually, we do regression testing in the following cases:
Read a detailed guide on Regression Testing
Regression Testing: Testing team re-execute the tests against the modified application to make sure whether the modified code breaks anything which was working earlier.
Confirmation Testing: Usually testers report a bug when a test fails. Dev Team releases a new version of the software after the defect is fixed. Now the testing team will retest to make sure the reported bug is actually fixed or not.
Graphical User Interface Testing is to test the interface between the application and the end user.
Recovery testing is performed in order to determine how quickly the system can recover after the system crash or hardware failure. It comes under the type of non-functional testing.
Globalization is a process of designing a software application so that it can be adapted to various languages and regions without any changes.
Refer Globalization Testing.
Localization is a process of adapting globalization software for a specific region or language by adding local specific components.
It is to check whether the application is successfully installed and it is working as expected after installation.
It is a process where the testers test the application by having pre-planned procedures and proper documentation.
Identify the modules or functionalities which are most likely cause failures and then testing those functionalities.
It is to deploy and check whether the application is working as expected in a different combination of environmental components.
Usually, this process will be carried out by domain experts. They perform testing just by exploring the functionalities of the application without having the knowledge of the requirements. Check our detailed guide on Exploratory Testing and also don’t miss these popular Exploratory Testing Tools .
Perform abnormal action on the application deliberately in order to verify the stability of the application. Check our in-depth guide on Monkey Testing .
To verify whether the application is user-friendly or not and was comfortably used by an end-user or not. The main focus in this testing is to check whether the end-user can understand and operate the application easily or not. An application should be self-exploratory and must not require training to operate it. Check this guide to learn how to perform Usability Testing .
Security testing is a process to determine whether the system protects data and maintains functionality as intended.
Running a system at high load for a prolonged period of time to identify the performance problems is called Soak Testing.
Endurance testing is a non-functional testing type. It is also known as Soak Testing. Refer Soak testing.
This type of testing determines or validates the speed, scalability, and/or stability characteristics of the system or application under test. Performance is concerned with achieving response times, throughput, and resource-utilization levels that meet the performance objectives for the project or product.
Complete Tutorial: Performance Testing
It is to verify that the system/application can handle the expected number of transactions and to verify the system/application behavior under both normal and peak load conditions.
It is to verify that the system/application can handle a large amount of data
It is to verify the behavior of the system once the load increases more than its design expectations.
Scalability testing is a type of non-functional testing. It is to determine how the application under test scales with increasing workload.
Concurrency testing means accessing the application at the same time by multiple users to ensure the stability of the system. This is mainly used to identify deadlock issues.
Fuzz testing is used to identify coding errors and security loopholes in an application. By inputting a massive amount of random data to the system in an attempt to make it crash to identify if anything breaks in the application.
Ad-hoc testing is quite opposite to the formal testing. It is an informal testing type. In Adhoc testing, testers randomly test the application without following any documents and test design techniques. This testing is primarily performed if the knowledge of testers in the application under test is very high. Testers randomly test the application without any test cases or any business requirement document.
Interface testing is performed to evaluate whether two intended modules pass data and communicate correctly to one another.
Perform testing on the application continuously for long period of time in order to verify the stability of the application
Bucket testing is a method to compare two versions of an application against each other to determine which one performs better.
Refer Bucket Testing.

Testing all the functionalities using all valid and invalid inputs and preconditions is known as Exhaustive testing.
Defects detected in early phases of SDLC are less expensive to fix. So conducting early testing reduces the cost of fixing defects.
Defect clustering in software testing means that a small module or functionality contains most of the bugs or it has the most operational failures.
Pesticide Paradox in software testing is the process of repeating the same test cases, again and again, eventually, the same test cases will no longer find new bugs. So to overcome this Pesticide Paradox, it is necessary to review the test cases regularly and add or update them to find more defects.
Defect cascading in Software testing means triggering of other defects in an application. When a defect is not identified or goes unnoticed while testing, it invokes other defects. It leads to multiple defects in the later stages and results in an increase in a number of defects in the application.
For example, if there is a defect in an accounting system related to negative taxation then the negative taxation defect affects the ledger which in turn affects other reports such as Balance Sheet, Profit & Loss etc.,
Outsourced Testing vs Crowdsourced Testing
|Outsource Testing||Crowdsourced testing|
|A dedicated team is present to handle your testing Needs we can say it’s a third party which is unknown to you, test your application or product with a fresh set of mind.||A completely unknown pool of testing resources test your application, you can judge the quality of your product on the basis of number of bugs reported.|
|Payment is done on the basis of hours spent in testing, this estimation is done prior to the testing cycle. As an example testing outsourcing costs around 20 to 40$ per hour.||Payment is done on the basis of bug reported, no of severe bugs and low priority bugs. For example severe bug cost is 15$ and low priority bug is 3$ whereas medium priority bugs are costing 5$.|
|Application data is kept confidential and this is one of the code of ethics of every testing provider company.||Since there are n number of testers working on your application and they are not legally bound with Crowd source provider company, they are not bound to keep application data confidential. There are chances of data leakage if crowd source testing is done and no assurance of data privacy.|
|Communication is quite easy, because there is one representative always present to handle to share testing status, quality of your product.||Communication is bit tricky, because you have to understand the product quality on the basis of bugs logged by testers, you have to understand the bug by talking to the tester individually.|
|Quality is not compromised, since the objective is to identify all the bugs, within time and within budget. Entire team works to achieve this milestone, They present potential and valid bugs and organization is confident enough to fix only those bugs and get assured about their product quality.||Since there is no team concept, here focus is more on Quantity rather than quality. There are chances that your application is tested by 1000 of testers of different experiences. They may log 5K bugs of different severity. So its organization’s responsibility to identify the real bugs and fix them.|
|Testing platform and environment is completely owned by outsourced company, they are well settled with all useful software, tools, management tools, OS and Devices.||Testing environment is totally dependent on individual tester, some testers are on testing on MAC machine or some are testing on Windows, some are testing on Android or some are testing on Apple.|
|Skilled testers are in the team, there are fixed no of testers in the team. Each tester is well skilled in a particular area like mobile testing, performance testing, automation testing, functional testing.||Huge no of testers, with different expertise and different years of experiences, so chances of quality bugs depends of expertise of testers. Which may be surprisingly good or bad too.|
|One team, one time zone, restricted deadline, and planned budget, in this way testing cycles are complete.||No team concept, Different time zones, no deadlines but bugs are reported very fast.|
|Bugs reported are generally predictive in nature because testers work within a scope of testing.
They don’t touch few areas because it may not in their budget.
|Here no limitations of testing scope, N no of testers, n no of directions of breaking the system, Due to this testing cycle goes through a real scenario, for example n number of users are accessing application they might get some security flaw in the application.|
|High paid in comparison to Crowd sourced testing but lesser than Inhouse Testing team.||Budget friendly, quick results some time real and unexpected issues are identified.|
A walkthrough is an informal meeting conducts to learn, gain understanding, and find defects. The author leads the meeting and clarifies the queries raised by the peers in the meeting.
Inspection is a formal meeting lead by a trained moderator, certainly not by the author. The document under inspection is prepared and checked thoroughly by the reviewers before the meeting. In the inspection meeting, the defects found are logged and shared with the author for appropriate actions. Post inspection, a formal follow-up process is used to ensure a timely and corrective action.
Author, Moderator, Reviewer(s), Scribe/Recorder and Manager.
The variation between the actual results and expected results is known as a defect. If a developer finds an issue and corrects it by himself in the development phase then it’s called a defect. Click here for more details.
If testers find any mismatch in the application/system in testing phase then they call it as Bug. Click here for more details.
We can’t compile or run a program due to a coding mistake in a program. If a developer unable to successfully compile or run a program then they call it as an error. Click here for more details.
Once the product is deployed and customers find any issues then they call the product as a failure product. After release, if an end user finds an issue then that particular issue is called as a failure. Click here for more details.
Bug/Defect severity can be defined as the impact of the bug on customer’s business. It can be Critical, Major or Minor. In simple words, how much effect will be there on the system because of a particular defect. Click here for more details.
Defect priority can be defined as how soon the defect should be fixed. It gives the order in which a defect should be resolved. Developers decide which defect they should take up next based on the priority. It can be High, Medium or Low. Most of the times the priority status is set based on the customer requirement. Click here for more details.
High Priority & High Severity: Submit button is not working on a login page and customers are unable to login to the application
Low Priority & High Severity: Crash in some functionality which is going to deliver after couple of releases
High Priority & Low Severity: Spelling mistake of a company name on the homepage
Low Priority & Low Severity: FAQ page takes a long time to load
Click here for more details.
A critical bug is a show stopper which means a large piece of functionality or major system component is completely broken and there is no workaround to move further.
For example, Due to a bug in one module, we cannot test the other modules because that blocker bug has blocked other modules. Bugs which affects the customers business are considered as critical.
1. “Sign In” button is not working on Gmail App and Gmail users are blocked to login to their accounts.
2. An error message pops up when a customer clicks on transfer money button in a Banking website.
Standalone applications follow one-tier architecture. Presentation, Business, and Database layer are in one system for a single user.
Client-server applications follow two-tier architecture. Presentation and Business layer are in a client system and Database layer on another server. It works majorly in Intranet.
Web server applications follow three-tier or n-tier architecture. The presentation layer is in a client system, a Business layer is in an application server and Database layer is in a Database server. It works both in Intranet and Internet.
Bug life cycle is also known as Defect life cycle. In Software Development process, the bug has a life cycle. The bug should go through the life cycle to be closed. Bug life cycle varies depends upon the tools (QC, JIRA etc.,) used and the process followed in the organization. Click here for more details.
A bug which is actually missed by the testing team while testing and the build was released to the Production. If now that bug (which was missed by the testing team) was found by the end user or customer then we call it as Bug Leakage.
Releasing the software to the Production with the known bugs then we call it as Bug Release. These known bugs should be included in the release note.
Defect age can be defined as the time interval between date of defect detection and date of defect closure.
Defect Age = Date of defect closure – Date of defect detection
Assume, a tester found a bug and reported it on 1 Jan 2016 and it was successfully fixed on 5 Jan 2016. So the defect age is 5 days.
Error seeding is a process of adding known errors intendedly in a program to identify the rate of error detection. It helps in the process of estimating the tester skills of finding bugs and also to know the ability of the application (how well the application is working when it has errors.)
Error guessing is also a method of test case design similar to error seeding. In error guessing, testers design test cases by guessing the possible errors that might occur in the software application. The intention is to catch the errors immediately.
A showstopper defect is a defect which won’t allow a user to move further in the application. It’s almost like a crash.
Assume that login button is not working. Even though you have a valid username and valid password, you could not move further because the login button is not functioning.
A bug that needs to handle as a high priority bug and fix it immediately.
There are four strategies to be followed for the rollout of any software testing project are as follows:
Boundary value analysis (BVA) is based on testing the boundary values of valid and invalid partitions. The Behavior at the edge of each equivalence partition is more likely to be incorrect than the behavior within the partition, so boundaries are an area where testing is likely to yield defects. Every partition has its maximum and minimum values and these maximum and minimum values are the boundary values of a partition. A boundary value for a valid partition is a valid boundary value. Similarly, a boundary value for an invalid partition is an invalid boundary value. Click here for more details.
Equivalence Partitioning is also known as Equivalence Class Partitioning. In equivalence partitioning, inputs to the software or system are divided into groups that are expected to exhibit similar behavior, so they are likely to be proposed in the same way. Hence selecting one input from each group to design the test cases. Click here for more details.
Decision Table is aka Cause-Effect Table. This test technique is appropriate for functionalities which has logical relationships between inputs (if-else logic). In the Decision table technique, we deal with combinations of inputs. To identify the test cases with a decision table, we consider conditions and actions. We take conditions as inputs and actions as outputs. Click here for more details.
Using state transition testing, we pick test cases from an application where we need to test different system transitions. We can apply this when an application gives a different output for the same input, depending on what has happened in the earlier state. Click here for more details.
The prerequisites that must be achieved before commencing the testing process. Click here for more details.
The conditions that must be met before testing should be concluded. Click here for more details.
Software Development Life Cycle (SDLC) aims to produce a high-quality system that meets or exceeds customer expectations, works effectively and efficiently in the current and planned information technology infrastructure, and is inexpensive to maintain and cost-effective to enhance.
Click here for more details.
We can do System Testing only when all the units are in place and working properly. It can only be done before User Acceptance Testing (UAT).
Manual testing is crucial for testing software applications more thoroughly. The procedure of manual testing comprises of the following.
1. Planning and Control
2. Analysis and Design
3. Implementation and Execution
4. Evaluating and Reporting
5. Test Closure activities
Refer Software Development Life Cycle (SDLC) & Software Testing Life Cycle (STLC)
STLC (Software Testing Life Cycle) identifies what test activities to carry out and when to accomplish those test activities. Even though testing differs between Organizations, there is a testing life cycle. Click here for more details.
Requirements Traceability Matrix (RTM) is used to trace the requirements to the tests that are needed to verify whether the requirements are fulfilled. Requirement Traceability Matrix AKA Traceability Matrix or Cross Reference Matrix. Click here for more details.
Software test metrics is to monitor and control process and product. It helps to drive the project towards our planned goals without deviation. Metrics answer different questions. It’s important to decide what questions you want answers to. Click here for more details.
There are many factors involved in real-time projects to decide when to stop testing.

124. What is API Testing?
API testing is a type of software testing that involves testing APIs directly and also as a part of integration testing to check whether the API meets expectations in terms of functionality, reliability, performance, and security of an application. In API Testing our main focus will be on a Business logic layer of the software architecture . API testing can be performed on any software system which contains multiple APIs. API testing won’t concentrate on the look and feel of the application. API testing is entirely different from GUI Testing.
Learn API Testing
The simple answer is black-box test cases are written first.
Let’s see why black-box test cases are written first compared to white box test cases.
Prerequisites to start writing black-box test cases are Requirement documents or design documents. These documents will be available before initiating a project.
Prerequisites to start writing white box test cases are the internal architecture of the application. The internal architecture of the application will be available in the later part of the project i.e., designing.
Workbench is a practice of documenting how a specific activity must be performed. It is often referred to as phases, steps, and tasks.
In every workbench there will be five tasks such as Input, Execute, Check, Output, and rework.
In random testing is a form of black-box software testing technique where the application is testing by generating random data.
