Manual Tester Interview Questions For 2025!
In the rapidly evolving world of software development, manual testing remains a critical component of ensuring software quality. For college students and freshers aspiring to launch their careers in software quality assurance, navigating manual testing interview questions can be challenging.
This comprehensive guide is designed to equip you with the knowledge, insights, and confidence to excel in your manual testing job interviews.
What is Manual Testing?
Manual testing involves manually verifying the functionality, usability, and overall performance of a software application. Testers perform test cases without using automation tools, ensuring the software meets requirements.
It helps identify defects, improve quality, and deliver error-free software. Interviews for manual testing roles demand a good understanding of:
- Testing fundamentals.
- Writing and executing test cases.
- Real-world problem-solving abilities.
Importance of Manual Testing
Before diving into common interview questions, it’s essential to understand the importance of manual testing. While automation testing has gained significant traction, manual testing continues to be indispensable in:
- Exploring complex scenarios that automated tests might miss
- Conducting usability and exploratory testing
- Identifying user experience and interface-related issues
- Providing a human perspective on software functionality
Manual Testing Interview Questions for Freshers
If you’re a fresher, interviewers primarily assess your theoretical knowledge and basic understanding of manual testing. Below are some commonly asked questions:
What is Manual Testing?
Manual testing is a software testing process where testers manually execute test cases without using automation tools. Testers physically interact with the software, comparing actual results with expected results. Key points to highlight:
- Involves human observation and critical thinking
- Requires detailed documentation
- Enables discovery of complex user experience issues
Explain the Difference Between Manual and Automated Testing
When answering this common interview question, focus on:
Manual Testing:
- Human-driven testing process
- Suitable for exploratory and usability testing
- More flexible and adaptable
- Lower initial setup cost
- Better for detecting visual and user experience issues
Automated Testing:
- Tool-driven testing process
- Ideal for repetitive and regression testing
- Faster execution of test cases
- Higher initial investment
- Consistent and repeatable test scenarios
What are the Different Types of Manual Testing?
Comprehensive testing types include:
Functional Testing
- Validates software against functional requirements
- Ensures each function performs as expected
- Examples: Unit testing, integration testing, system testing
Non-Functional Testing
- Evaluate non-functional aspects of software
- Includes performance, usability, and security testing
- Focuses on system behavior under various conditions
Structural Testing
- Examines internal code structure
- Ensures code meets specific design requirements
- Involves white-box and gray-box testing techniques
What is a test case?
A test case is a set of conditions or actions created to validate a specific feature or functionality of a software application. Example:
Test Case ID: TC_01
Test Case Description: Verify the login functionality.
Precondition: The user must have valid login credentials.
Test Steps: Open the application, enter credentials, and click ‘Login.’
Expected Result: The user successfully logs in.
What are the different levels of testing?
- Unit Testing
- Integration Testing
- System Testing
- Acceptance Testing
Explain the difference between verification and validation.
- Verification: Ensures the product is built correctly by checking design documents, code, and plans.
- Validation: Ensures the right product is built by validating the functionality against user needs.
Software Manual Testing Interview Questions and Answers
Below are some commonly asked Software Manual Testing Interview questions with answers:
What are the types of manual testing?
- Black Box Testing: Testing without knowing internal code.
- White Box Testing: Testing with code knowledge.
- Regression Testing: Ensuring new changes don’t affect existing functionality.
- Smoke Testing: Verifying basic application functionality.
- Ad-hoc Testing: Unstructured testing to identify bugs creatively.
What is the defect life cycle?
The defect life cycle includes:
- New: Bug reported.
- Assigned: Bug assigned to the developer.
- Open: Developer begins work.
- Fixed: Issue resolved.
- Closed: Tester confirms the fix.
- Reopen: The bug still exists.
What tools are used in manual testing?
Common tools include:
- Test Management Tools: Jira, TestRail.
- Defect Tracking Tools: Bugzilla, Mantis.
- Documentation Tools: Confluence, Excel.
How would you test a login page?
Break the testing into:
- Positive Testing: Input valid username and password, click “Login,” and verify successful login.
- Negative Testing: Use invalid credentials and ensure proper error messages are displayed.
What would you do if you found a bug?
- Reproduce the bug to confirm its existence.
- Document the bug with details like steps, expected vs. actual behavior, screenshots, and environment.
- Report the bug in the tracking tool (e.g., Jira).
How would you test an e-commerce website’s “Add to Cart” functionality?
Steps to Test:
- Log in to the e-commerce website.
- Navigate to a product listing page.
- Select a product and click “Add to Cart.”
- Verify that the product appears in the cart with the correct details (name, price, quantity).
- Perform negative testing, such as adding the product without being logged in or adding more items than available stock.
Expected Result: The cart should update correctly with the selected product details, and appropriate error messages should be displayed for invalid actions.
How would you test the password reset functionality of a website?
Steps to Test:
- Navigate to the login page and click on “Forgot Password.”
- Enter a valid email ID and check if a reset link is sent.
- Test with an invalid or non-registered email and verify the error message.
- Use the reset link and ensure it redirects to the password reset page.
- Enter a new password and confirm it works by logging in.
Expected Result: The reset process should be smooth, and the new password should replace the old one without affecting the account.
How would you test a mobile app’s notification feature?
Steps to Test:
- Enable notifications in the app and the device settings.
- Trigger an action that sends a notification (e.g., message or alert).
- Verify if the notification appears on the device as expected.
- Test with notifications disabled to confirm they don’t appear.
- Test for correct content and functionality when tapping the notification.
Expected Result: Notifications should display accurately when enabled and not appear when disabled. Tapping them should redirect them to the correct in-app location.
Succeeding in manual testing interviews requires a blend of technical knowledge, practical skills, and the right attitude. By understanding core concepts, preparing thoroughly, and demonstrating problem-solving abilities, freshers can confidently navigate their manual testing career journey.
