The primary goal of manual testing is to identify bugs or defects in the software application before it goes live. This process involves a tester taking on the role of an end user and testing the software to ensure it behaves as expected.
Manual testing is crucial in the software development lifecycle (SDLC) as it helps ensure that the application meets the specified requirements and provides a good user experience. It is particularly useful in scenarios where the application is still in the early stages of development or when the testing process requires human observation and intuition.
Key Concepts and Terminologies
Understanding manual testing requires familiarity with several key concepts and terminologies:
- Test Case: A set of conditions or variables under which a tester will determine whether an application or software system is working correctly.
- Test Plan: A document detailing the scope, approach, resources, and schedule of intended testing activities.
- Defect/Bug: An error, flaw, or unintended behavior in the software that causes it to produce incorrect or unexpected results.
- Test Scenario: A high-level description of what to test, outlining the functionality to be tested.
- Regression Testing: Testing existing software applications to ensure that a change or addition hasn’t introduced new bugs.
- Acceptance Testing: A type of testing conducted to determine whether the system satisfies the acceptance criteria and is ready for deployment.
Types of Manual Testing
Manual testing can be categorized into several types, each serving a specific purpose in the testing process. Here are the most common types:
Black Box Testing
Black box testing is a testing technique where the tester evaluates the functionality of an application without peering into its internal structures or workings. The tester focuses on inputs and outputs, ensuring that the software behaves as expected based on the requirements.
Example: If a user is testing a login feature, they would input various usernames and passwords to see if the application correctly allows or denies access, without needing to know how the login process is implemented in the code.
White Box Testing
White box testing, also known as clear box testing, is a testing method where the tester has knowledge of the internal workings of the application. This type of testing involves looking at the code structure, logic, and flow of the application to identify potential issues.
Example: A tester might write test cases that cover specific code paths, ensuring that all branches of a conditional statement are executed during testing.
Grey Box Testing
Grey box testing is a combination of black box and white box testing. In this approach, the tester has partial knowledge of the internal workings of the application, allowing them to design test cases that are more effective than black box testing alone.
Example: A tester might know the database structure of an application and use that knowledge to create test cases that validate data integrity while also testing the user interface.

Advanced Questions
What is Regression Testing?
Regression Testing is a type of software testing that ensures that recent changes or additions to the codebase have not adversely affected the existing functionality of the application. This testing is crucial in maintaining the integrity of the software after updates, bug fixes, or enhancements. The primary goal is to catch any unintended side effects that may arise from changes made to the code.
For example, consider a scenario where a new feature is added to an e-commerce application that allows users to filter products by price. After implementing this feature, regression testing would involve running a suite of tests on the existing functionalities, such as the checkout process, user login, and product search, to ensure that these features still work as intended.
Regression tests can be manual or automated. Automated regression testing is particularly beneficial for large applications with frequent updates, as it allows for quicker feedback and more extensive coverage. Tools like Selenium, TestComplete, and QTP are commonly used for automating regression tests.
Explain the concept of Smoke Testing.
Smoke Testing, often referred to as “build verification testing,” is a preliminary level of testing conducted to check the basic functionality of an application. The primary purpose of smoke testing is to ascertain whether the most critical functions of the software are working correctly after a new build or version is deployed. It acts as a gatekeeper, determining whether the build is stable enough to proceed with further testing.
For instance, in a web application, smoke tests might include verifying that the application launches successfully, the login functionality works, and the main pages load without errors. If any of these critical functions fail during smoke testing, the build is rejected, and the development team is notified to address the issues before further testing is conducted.
Smoke testing is typically automated to save time and ensure consistency. It is a quick way to identify major issues early in the testing process, allowing teams to focus their efforts on more in-depth testing only when the build passes the smoke tests.
What is Sanity Testing?
Sanity Testing is a subset of regression testing that focuses on verifying specific functionalities after changes have been made to the application. Unlike smoke testing, which checks the overall functionality of the application, sanity testing is more targeted and is performed to ensure that particular bugs have been fixed or that new features work as intended.
For example, if a bug was reported in the user registration process, sanity testing would involve checking that the registration feature works correctly after the bug fix. It may also include verifying that the changes made did not introduce new issues in related functionalities.
Sanity testing is usually performed manually, but it can also be automated if the tests are repetitive. The key difference between sanity and smoke testing is that sanity testing is more focused and is conducted after receiving a stable build, while smoke testing is broader and is performed on initial builds to check for critical issues.
How do you perform Boundary Value Analysis?
Boundary Value Analysis (BVA) is a testing technique that focuses on the values at the boundaries of input ranges rather than the center. This method is based on the observation that errors often occur at the edges of input ranges. BVA is particularly useful for testing input fields that accept numerical values, such as age, salary, or any other quantifiable data.
To perform Boundary Value Analysis, follow these steps:
- Identify the input range: Determine the valid input range for the variable you are testing. For example, if a field accepts ages from 18 to 60, the valid range is 18 to 60.
- Identify boundary values: Identify the boundary values, which include the minimum and maximum values, as well as values just outside the boundaries. In our example, the boundary values would be 17, 18, 60, and 61.
- Design test cases: Create test cases that include the boundary values and values just inside and outside the boundaries. For the age example, test cases would include 17, 18, 30, 60, and 61.
By focusing on these boundary values, testers can effectively identify potential issues that may not be apparent when testing only the values within the range. This technique helps ensure that the application behaves correctly at the limits of its input specifications.
What is Equivalence Partitioning?
Equivalence Partitioning is a testing technique that divides input data into partitions or groups that are expected to exhibit similar behavior. The idea is that if one test case from a partition passes, all other test cases in that partition are likely to pass as well. This method helps reduce the number of test cases while still providing adequate coverage of the input space.
To apply Equivalence Partitioning, follow these steps:
- Identify the input conditions: Determine the input conditions for the feature you are testing. For example, if a field accepts ages from 18 to 60, the input conditions would be ages less than 18, ages between 18 and 60, and ages greater than 60.
- Define equivalence classes: Create equivalence classes based on the input conditions. In our example, the classes would be:
- Invalid class: Ages less than 18 (e.g., 17, 16)
- Valid class: Ages between 18 and 60 (e.g., 18, 30, 60)
- Invalid class: Ages greater than 60 (e.g., 61, 62)
- Design test cases: Select one representative value from each equivalence class to create your test cases. For instance, you might choose 17 (invalid), 30 (valid), and 61 (invalid) as your test cases.
By using Equivalence Partitioning, testers can efficiently cover a wide range of input scenarios with fewer test cases, making the testing process more efficient while still ensuring that the application behaves correctly across different input conditions.

Explain the concept of Test Coverage.
Test Coverage is a measure of how much of the application’s code or functionality is tested by the test cases. It helps in identifying untested parts of the application and ensures that the testing process is thorough. Test coverage can be expressed in various ways, including:
- Code Coverage: This measures the percentage of code that is executed during testing. It can be further broken down into different types, such as:
- Statement Coverage: The percentage of executable statements that have been executed.
- Branch Coverage: The percentage of branches (if-else conditions) that have been executed.
- Function Coverage: The percentage of functions or methods that have been called during testing.
- Requirement Coverage: This measures the percentage of requirements that have corresponding test cases. It ensures that all functional requirements are validated.
- Test Case Coverage: This measures the percentage of test cases that have been executed against the total number of test cases designed.
High test coverage is generally desirable as it indicates that a significant portion of the application has been tested. However, it is important to note that 100% test coverage does not guarantee the absence of defects. Therefore, while aiming for high coverage, it is equally important to focus on the quality of the test cases and the scenarios they cover.

- Integration Testing: Testing the interaction between different modules or systems to ensure they work together seamlessly.
- System Testing: Validating the complete and integrated software product to ensure it meets the specified requirements.
3. What is the difference between Verification and Validation?
Verification and validation are two critical aspects of the software testing process:
- Verification: This process ensures that the product is being built correctly, focusing on the development process. It answers the question, “Are we building the right product?” Verification activities include reviews, inspections, and static testing.
- Validation: This process checks whether the product meets the user needs and requirements. It answers the question, “Are we building the product right?” Validation activities include dynamic testing, such as executing test cases and user acceptance testing.
4. What is a Test Case, and what are its components?
A test case is a set of conditions or variables under which a tester will determine whether a system or software application is working correctly. The components of a test case typically include:
- Test Case ID: A unique identifier for the test case.
- Test Description: A brief description of what the test case will validate.
- Preconditions: Any conditions that must be met before executing the test.
- Test Steps: Detailed steps to execute the test.
- Expected Result: The anticipated outcome of the test.
- Actual Result: The actual outcome after executing the test.
- Status: Indicates whether the test case passed or failed.
5. How do you prioritize test cases?
Prioritizing test cases is crucial for effective testing, especially when time and resources are limited. Test cases can be prioritized based on several factors:
- Risk Assessment: High-risk areas that could lead to significant issues if they fail should be tested first.
- Business Impact: Test cases that affect critical business functions should be prioritized.
- Complexity: More complex features may require more thorough testing and should be prioritized accordingly.
- Frequency of Use: Features that are used more frequently should be tested more rigorously.
6. What is a Bug Life Cycle?
The bug life cycle describes the various stages a bug goes through from its discovery to its resolution. The typical stages include:
- New: The bug is identified and logged.
- Assigned: The bug is assigned to a developer for fixing.
- Open: The developer starts working on the bug.
- Fixed: The developer has fixed the bug and it is ready for retesting.
- Retest: The tester verifies that the bug has been fixed.
- Closed: The bug is confirmed as fixed and is closed.
- Reopened: If the bug persists, it can be reopened for further investigation.
7. What tools do you use for Manual Testing?
While manual testing primarily involves human effort, various tools can assist testers in managing their tasks more efficiently. Some popular tools include:
- JIRA: A project management tool that helps track bugs and issues.
- TestRail: A test case management tool that allows testers to organize and manage test cases.
- Bugzilla: An open-source bug tracking system that helps manage software defects.
- Postman: A tool for testing APIs manually.
8. How do you handle a situation where you find a critical bug just before the release?
Finding a critical bug just before a release can be stressful. Here’s how to handle it:
- Assess the Impact: Determine the severity of the bug and its impact on the user experience and business operations.
- Communicate: Inform the relevant stakeholders, including developers and project managers, about the bug and its implications.
- Collaborate: Work with the development team to understand the feasibility of fixing the bug before the release.
- Document: Ensure that the bug is documented for future reference, regardless of whether it is fixed before the release.
- Make a Decision: Based on the assessment, decide whether to delay the release or proceed with it, keeping in mind the potential risks.
