Top 20 Tech Mahindra Technical Interview Questions and Answers
1. What is the difference between manual testing and automated testing?
Manual testing is a software testing process where test cases are executed manually by a tester without using any automated tools. The tester verifies that the actual results match the expected results and documents the process. Automated testing is a software testing process where test scripts are executed using automated tools. It helps to reduce time and cost of the testing process, and it increases the test coverage. Automated testing also helps to reduce human errors and increase the accuracy of the testing results.
2. What do you know about software development life cycle (SDLC)?
Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop and test software. It is a sequential process that includes the following stages: Requirement Analysis, Design, Development, Testing, Deployment, and Maintenance. Each stage must be completed before the next stage can start, and each stage has its own purpose and objectives. At each stage, different activities such as coding, testing, and debugging are involved.
3. What is the importance of software testing?
Software testing is important for ensuring quality and reliability of the software. It helps to detect software defects early in the development process, which helps to reduce the cost and time of the development process. Software testing also helps to ensure that the software meets the user requirements and is working properly.
4. What are some common software testing tools?
Some of the most common software testing tools are Selenium, Appium, SoapUI, LoadRunner, JUnit, TestComplete, Ranorex, and QTP (QuickTest Professional). Each of these tools has its own advantages and disadvantages, and they can be used for different types of software testing.
5. What is the difference between debugging and testing?
Debugging is a software development process that involves finding and resolving defects or bugs in software code. It is usually done manually by a developer, and it requires analysis and problem-solving skills. Testing is a process that is used to check whether the software is working correctly according to the user requirements. It involves executing test cases and verifying the expected results with the actual results.
6. Explain the different types of software testing.
Software testing can be divided into two main categories: functional testing and non-functional testing. Functional testing involves testing the functionality of the software, such as verifying that the user interface works correctly, that the user can enter data correctly, etc. Non-functional testing involves testing the performance, reliability, scalability, and security of the software.
7. What is a bug?
A bug is a defect in the software code that causes the software to behave unexpectedly or not work as intended. Bugs can be caused by errors in coding, design, or logic.
8. What is test coverage and why is it important?
Test coverage is a measure of how much of the code has been tested. It is important because it helps to ensure that all the code has been tested and that no defects have been missed.
9. What is a test case?
A test case is a set of conditions or variables under which a tester will determine whether a system under test behaves as expected. It consists of inputs, expected results, and steps to be performed to verify the results.
10. What is a unit test?
A unit test is a type of software testing that focuses on individual units or components of a software environment. Unit tests are typically written by the developers, and they are used to verify that the code is working as expected.
11. What is an integration test?
An integration test is a type of software testing that is used to test how different components or modules of a software system interact with each other. It is done after unit tests have been completed, and it helps to ensure that the components are working together correctly.
12. What is a regression test?
A regression test is a type of software testing that is used to ensure that changes made to the software do not cause unintended side effects or break existing functionality. It is performed after code changes have been made to ensure that the changes did not cause any unexpected behavior.
13. What is the purpose of a smoke test?
A smoke test is a type of software testing that is used to verify that the basic functionality of the software is working correctly. It is usually done after a major change has been made to the code, such as adding a new feature or fixing a defect, to ensure that the changes did not break any existing functionality.
14. What is the difference between white box testing and black box testing?
White box testing is a type of software testing that involves testing the internal structure of the software, such as code, logic, and algorithms. Black box testing is a type of software testing that involves testing the external behavior of the software, such as user interface and user experience.
15. What is acceptance testing?
Acceptance testing is a type of software testing that is used to determine whether the software meets the requirements specified by the user. It is usually performed by the end-users of the software, and it helps to ensure that the software meets the user’s expectations.
16. What is usability testing?
Usability testing is a type of software testing that is used to measure the user-friendliness of the software. It is usually done by end-users, and it helps to determine how easy and intuitive the software is to use.
17. What is performance testing?

18. What is security testing?
Security testing is a type of software testing that is used to check the security of the software. It involves testing the authentication, authorization, and encryption mechanisms of the software to ensure that the user data is secure.
19. What is the difference between unit testing and integration testing?
Unit testing is a type of software testing that focuses on individual units or components of a software environment. It is usually done by developers, and it helps to verify that the code is working as expected. Integration testing is a type of software testing that is used to test how different components or modules of a software system interact with each other. It is done after unit tests have been completed, and it helps to ensure that the components are working together correctly.
20. What is agile testing?
Agile testing is a type of software testing that is used to ensure that the software meets the user requirements in an iterative fashion. It is based on the principles of the Agile software development methodology, which focuses on delivering working software quickly and iteratively.
