Basic Manual Testing Interview Questions (1-10)
1. What is Manual Testing?
Manual Testing is the process of manually executing test cases without using any automation tools to validate that the software application works as expected according to the requirements.
2. What are the roles and responsibilities of a Manual Tester?
Key responsibilities include analyzing client requirements, reviewing code for compliance, creating test environments, organizing review meetings, executing test cases, detecting bugs, and monitoring system errors with the team.
3. What is the difference between Verification and Validation in Manual Testing?
Verification checks if we are building the product right (process-oriented), while Validation ensures we are building the right product (product-oriented).
4. What is the Software Testing Life Cycle (STLC)?
STLC includes requirement analysis, test planning, test case design, test environment setup, test execution, and test closure activities.
5. What are the steps involved in the Manual Testing Process?
The steps are: requirement analysis, test plan creation, designing test scenarios and cases, test execution and defect reporting, evaluating exit criteria, and test closure.
6. What is a Test Case?
A Test Case is a document detailing input values, execution steps, preconditions, and expected results to verify a specific functionality.
7. What are the key components of a good Test Case?
A good test case includes test case ID, description, preconditions, test steps, test data, expected result, actual result, and status.
8. What skills are required for Manual Testing?
Essential skills include attention to detail, analytical ability, knowledge of SDLC/STLC, familiarity with Agile, and proficiency in test management tools.
9. What is Black Box Testing?
Black Box Testing focuses on testing the functionality of an application without knowing its internal code structure, based only on requirements.
10. What is White Box Testing?
White Box Testing involves testing internal structures and code logic, requiring knowledge of the program’s internals.
Intermediate Manual Testing Interview Questions (11-20)
11. What is Grey Box Testing?
Grey Box Testing combines black box and white box approaches, where the tester has partial knowledge of the internal code structure.
12. Explain Test Driver and Test Stub.
A Test Driver simulates the environment for testing a module, while a Test Stub replaces missing modules during testing.
13. What is the difference between Severity and Priority in Bug Tracking?
Severity measures the impact of a defect on the system, while Priority determines the urgency of fixing it.
14. What is Test Planning?
Test Planning outlines the testing approach, objectives, scope, resources, schedule, and deliverables for the testing project.
15. What are Entry and Exit Criteria in Testing?
Entry Criteria define conditions to start testing (e.g., requirements approved), while Exit Criteria define when to stop (e.g., 95% test cases passed).
16. What is Test Closure?
Test Closure involves evaluating test completion, documenting results, releasing resources, and archiving test artifacts for future reference.
17. How do you prioritize Test Cases?
Prioritize based on risk, business impact, and 80/20 rule—focus 20% of test cases that cover 80% of the application.
18. What is Exploratory Testing?
Exploratory Testing is an unscripted approach where testers explore the application simultaneously designing and executing tests.
19. What is Regression Testing?
Regression Testing verifies that recent code changes have not adversely affected existing functionalities.
20. Scenario: At Zoho, how would you test a new login feature manually?
Review requirements, design test cases for valid/invalid credentials, execute functional tests, check UI/UX, test edge cases like empty fields, and document defects.
Advanced Manual Testing Interview Questions (21-30)
21. What is the difference between Retesting and Regression Testing?
Retesting verifies a specific fixed defect, while Regression Testing checks the overall system after fixes.
22. Explain Defect Life Cycle.
Defect Life Cycle: New → Assigned → Open → Fixed → Retest → Verified → Closed or Reopened.
23. What are some challenges in Manual Testing and how to overcome them?
Challenges include repetitive tasks and human error. Overcome by using test management tools, prioritizing exploratory testing, and peer reviews.
24. How do you ensure Test Coverage in Manual Testing?
Categorize test cases by functionality, apply 80/20 rule, design modular cases, and eliminate duplicates.
25. What is Ad-hoc Testing?
Ad-hoc Testing is informal random testing without test cases to find defects overlooked by formal methods.
26. Scenario: During testing at Salesforce, you find inconsistent behavior across browsers. What do you do?
Document the defect with screenshots, steps to reproduce, browser versions, log details, and categorize as compatibility issue for priority fixing.
27. What is Sanity Testing?
Sanity Testing is a quick check to verify if major functionalities work after a build deployment, before full testing.
28. Scenario: In a Paytm-like payment app at Flipkart, a critical payment failure occurs. How do you report it?
Report with high severity/priority, include transaction ID, steps, screenshots, environment details, and impact on business.
29. What is the role of a Manual Tester in Agile Methodology?
In Agile, testers participate in sprint planning, create executable test cases, perform exploratory testing, and provide quick feedback in daily standups.
30. How would you test the search functionality in an Atlassian product like Jira manually?
Test valid/invalid searches, partial matches, sorting, pagination, no results scenario, special characters, performance under load, and accessibility.
