In today's competitive job market, a strong foundation in software testing is essential for ensuring the quality and reliability of applications. As companies strive to deliver seamless user experiences, skilled testers play a crucial role in identifying and addressing bugs before they reach the end user.

The testing interview process is designed to assess a candidate's technical expertise, problem-solving skills, and understanding of various testing methodologies. In this article, we will explore some of the most commonly asked testing interview questions, ranging from basic concepts to advanced techniques, to help aspiring testers prepare effectively and demonstrate their proficiency during interviews.

Most Asked Software Tester Interview Questions

I have mention some most asked technical Software Tester Interview Questions which help you to clear the interview. These questions for junior and senior Tester engineer.

1. What is the difference between Testing and debugging?
Testing means checking the behavior of the application whether it is expected or not. And
Testing can be done without any internal knowledge of software architecture. It’s done by a
tester.

Debugging means finding out the main cause of defects and debugging requires Internal
knowledge of the software architecture and coding. It’s done by the developer.

2. What is QAMS?
A quality management system is a collection of business processes focused on consistently
meeting customer requirements and enhancing their satisfaction. It is aligned with an
organization's purpose and strategic direction.

A quality management system (QMS) is a system that documents the policies, business processes,
and procedures necessary for an organization to create and deliver its products or services to its
customers, and therefore increase customer satisfaction through high product quality.

3. Explain the software release process in brief.
In the software release process, the project manager makes a release team consisting of
developers, testers, project management executives. This team goes to customers’ places and
deploys software products or they just deploy the software at the client’s server. The team also
delivers some training to customers regarding the functioning of software if required.

4. What is the difference between SDLC and STLC?
Software Development Life Cycle involves the complete Verification and Validation of a Process
or a Project.

Whereas Software Testing Life Cycle involves only Validation.

5. What is Test Closure?
Test Closure is final stage of STLC(Software Testing Life Cycle) where we will make all details documentations which are required
submit to client at time of software delivery. Such as test report, defect report, test cases summary,
RTM details, release note

6. What is the list of test closure documents?

1. Test case documents, (i.e., Test Case Excel sheet we prepare during actual testing)
2. Test plan, test strategy,
3. Release note
4. Test scripts,
5. Test data,
6. Traceability matrix, and
7. Test results and reports like bug report, execution report etc.

7. What is a Build?
It is a number/identity given to Installable software that is given to the testing team by the
development team.

8. What is release?
It is a number/ identity given to Installable software that is handed over to the customer/client
by the testing team (or sometimes directly by the development team).

9. What is a different attribute of test cases?
1. TestCaseID - A unique identifier of the test case.
2. Test Summary - One-liner summary of the test case.
3. Description - Detailed description of the test case.
4. Prerequisite or pre-condition - A set of prerequisites that must be followed before executing
the test steps.
5. Test Steps - Detailed steps for performing the test case.
6. Expected result - The expected result in order to pass the test.
7. Actual result - The actual result after executing the test steps.
8. Test Result - Pass/Fail status of the test execution.
9. Automation Status - Identifier of automation - whether the application is automated or not.
10. Date - The test execution date.
11. Executed by - Name of the person executing the test case.

10. What is the code freeze?
Code freeze means Finalization of code and no further changes will be happening in code.

11. What is your (QA/Tester) basic roles and responsibility?
1. Understanding & analyzing Test Requirements.
2. Prepare Test Scenarios for individual modules.
3. Writing & review the Test Cases as per requirements.
4. Test cases execution.
5. Defect creation, Defect verification, and QA task management.
6. Weekly Test status reporting.
7. Continuous Communication with the team & client.
8. Preparation of Test Plan Documentation (if have 3+ years exp).

12. Explain what should your QA documents include?
QA testing document should include
1. List the number of defects detected as per severity level
2. Explain each requirement or business function in detail
3. Inspection reports

4. Configurations
5. Test plans and test cases
6. Bug reports
7. User manuals
8. Prepare separate reports for managers and users

13. What is UAT ?
User Acceptance Testing (UAT) is a type of testing performed by the end-user or the client to
verify/accept the software system before moving the software application to the production
environment. UAT is done in the final phase of testing after functional, integration, and
system testing are done.

14. What us Scrum ?
Scrum is a framework through which we build the software product by following Agile
Principles.

15. Difference between Scrum and Waterfall.
Feedback from the customers is received at an early stage in Scrum than Waterfall.
New changes can easily accommodate in Scrum than the Waterfall.
Rollback or accommodate new changes is easy in Scrum.
Testing is considered a phase in the Waterfall, unlike Scrum.

16. Difference between Scum and Iterative Model.
Scrum is a type of Iterative model, but it is an Incremental + Iterative model. As we break the
product into small Incremental builds and then small pieces of builds are completed in
multiple iterations.

17. Mention different Tools for Non-Functional Testing.
1. JMeter
2. Loadster
3. LoadRunner
4. LoadStorm
5. NeoLoad
6. Forecast
7. Load Complete

18. Mention different Tools for Functional Testing
1. Selenium

2. QTP (HP Product)
3. SoapUI (This is API tool)

19. What qualities should a good Agile tester have?
1. One should be able to understand the requirements quickly.
2. One should know Agile concepts and principles.
3. As requirements keep changing, one should understand the risk involved in it.
4. The agile tester should be able to prioritize the work based on the requirements.
5. Communication is a must for an Agile tester as it requires a lot of communication with developers
and business associates.

20. How does agile testing (development) methodology differ from other testing (development)
methodologies?
In agile testing methodology, the entire testing process is broken into a small piece of codes and
in each step, these codes are tested. There are several processes or plans involved in this
methodology like communication with the team, short strategical changes to get the optimal
result, etc.

21. Describe the places where ‘Scrum’ and ‘Kanban’ are used?
‘Scrum’ is used when you need to shift towards a more appropriate or more prominent process
while if you want improvement in running the process without any changes in the whole scenario,
you should use ‘Kanban’.

22. Tell me one big advantage of using scrum?
The major advantage is – Early feedback from the client so if any changes are required those can
be done at the initial stage and producing the Minimal Viable Product to the stakeholders.

23. What is MVP in scrum?
A Minimum Viable Product is a product that has just the bare minimum required feature which
can be shown to the stakeholders and is eligible to be deployed to production.

In conclusion, preparing for a software testing interview requires a solid grasp of both theoretical knowledge and practical skills. By understanding key testing concepts, methodologies, and common interview questions, candidates can confidently showcase their abilities and stand out to potential employers.

Whether you’re a beginner looking to break into the field or an experienced professional aiming to advance your career, thorough preparation is key. By anticipating the types of questions you may encounter and practicing your responses, you can improve your chances of success and secure the role you desire. Ultimately, the ability to think critically, communicate clearly, and demonstrate a passion for quality assurance will set you apart in any testing interview.
