Manual Testing Questions and Answers for Freshers

If you are new to software testing, understanding basic manual testing concepts is essential. Here are the top 100 manual testing interview questions for freshers:

1. What is Manual Software Testing?

Manual testing is the process of manually executing test cases without using automation tools. Testers check for defects by following a predefined set of test cases to ensure that the application behaves as expected. It is used for exploratory testing, usability testing, and cases where automation is impractical.

2. What are the Advantages of Manual Testing?

  • Cost-effective for small projects.
  • Better suited for exploratory and usability testing.
  • Human-centric insights for better user experience.
  • No need for programming skills.
  • Flexible for dynamically changing requirements.

3. What are the Drawbacks of Manual Testing?

  • Time-consuming as tests must be executed manually.
  • Prone to human errors.
  • Less efficient for repetitive test cases.
  • Difficult to scale for large applications.
  • Not suitable for performance or load testing.

4. List Key Challenges of Manual Testing.

Manual testing comes with challenges such as maintaining detailed documentation, the need for skilled testers, determining the right order of tests, and knowing when to stop testing. Additionally, frequent requirement changes can make manual testing difficult to manage.

5. Additional Manual Testing Questions for Freshers:

  • What are the different types of manual testing?
  • What is black-box testing?
  • Explain white-box testing with an example.
  • What is exploratory testing, and when is it used?
  • What is regression testing?
  • Define test case, test scenario, and test script.
  • How do you write a good test case?
  • What is the difference between verification and validation?
  • Explain smoke testing vs. sanity testing.
  • What is a test plan, and why is it important?

Manual Testing Interview Questions for Experienced Testers

For professionals with experience, interviewers often focus on deeper manual testing concepts and real-world scenarios. Here are advanced manual testing interview questions:

6. What is a Test Driver?

A test driver is a piece of software used to execute test cases by simulating modules of an application. It is commonly used in integration testing when lower-level modules are available, but higher-level modules are yet to be developed.

7. What are the Skills Required for Manual Testing?

  • Strong analytical and logical thinking.
  • Good communication and documentation skills.
  • Understanding of SDLC and STLC.
  • Familiarity with bug tracking tools like JIRA.
  • Basic knowledge of SQL for database validation.
  • Knowledge of test management tools.
  • Attention to detail to identify edge cases.

8. What is API Testing in Manual Testing?

API testing involves testing application programming interfaces (APIs) manually to validate request-response mechanisms, authentication, and error handling. Tools like Postman can be used for manual API testing.

9. Additional Manual Testing Questions for Experienced Testers:

  • What is boundary value analysis (BVA)?
  • What is equivalence partitioning?
  • How do you handle frequently changing requirements?
  • What is defect lifecycle in testing?
  • Explain difference between test case and test script.
  • What are negative test cases, and why are they important?
  • What is a test harness?
  • What is user acceptance testing (UAT)?
  • How do you prioritize test cases?
  • How do you estimate testing efforts?
