Advanced Manual Testing Interview Questions

What is Exploratory Testing?

Exploratory testing is a hands-on approach to software testing that emphasizes the tester’s autonomy and creativity. Unlike scripted testing, where test cases are predefined and followed step-by-step, exploratory testing allows testers to explore the application freely, using their intuition and experience to identify defects. This method is particularly useful in situations where requirements are not well-defined or when time constraints limit the ability to create comprehensive test cases.

In exploratory testing, testers often use a combination of their domain knowledge, experience with similar applications, and an understanding of the user perspective to guide their testing efforts. The process typically involves:

• Session-Based Testing: Testers conduct testing sessions, often time-boxed, where they focus on specific areas of the application.
• Documentation: While exploratory testing is less formal, testers should document their findings, including any defects discovered and the steps taken during testing.
• Charters: Testers may create charters that outline the goals and scope of each testing session, helping to maintain focus.

For example, if a tester is exploring a new e-commerce website, they might start by navigating through the product pages, adding items to the cart, and checking the checkout process without a predefined script. This approach can uncover usability issues, unexpected behaviors, and other defects that might not be caught through traditional testing methods.

Explain the Concept of 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. The rationale behind BVA is that errors are more likely to occur at the edges of input ranges, making it a critical technique for identifying potential defects in software applications.

When applying BVA, testers identify the boundaries of input fields and create test cases that include:

• The minimum value just below the boundary
• The minimum value at the boundary
• The minimum value just above the boundary
• The maximum value just below the boundary
• The maximum value at the boundary
• The maximum value just above the boundary

For instance, if a field accepts values from 1 to 100, the boundary values would be 0, 1, 100, and 101. Test cases would be designed to check how the application handles these values, ensuring that it correctly accepts valid inputs and rejects invalid ones.

What is Equivalence Partitioning?

Equivalence Partitioning (EP) is another 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, thus reducing the number of test cases needed while still providing adequate coverage.

To apply equivalence partitioning, testers identify valid and invalid input ranges and create test cases for each partition. For example, consider a form that accepts ages from 18 to 65:

• Valid Partition: Ages 18 to 65 (e.g., 18, 30, 65)
• Invalid Partitions: Ages below 18 (e.g., 17, 0, -5) and ages above 65 (e.g., 66, 100)

By testing one representative value from each partition, testers can efficiently verify that the application behaves as expected across a range of inputs. This technique is particularly useful for input validation and boundary conditions.

How Do You Perform Usability Testing?

Usability testing is a critical aspect of software testing that focuses on evaluating the user experience of an application. The goal is to ensure that the software is user-friendly, intuitive, and meets the needs of its target audience. Here’s how to perform usability testing effectively:

2. Select Participants: Choose a representative group of users who match the target audience for the application. This could include both experienced users and novices.
3. Design Scenarios: Create realistic tasks for participants to complete during the test. These tasks should reflect common user goals and interactions with the application.
4. Conduct the Test: Observe participants as they interact with the application. Encourage them to think aloud, sharing their thoughts and feelings as they navigate through the tasks.
5. Collect Feedback: After the test, gather feedback from participants about their experience. This can include surveys, interviews, or informal discussions.
6. Analyze Results: Review the observations and feedback to identify usability issues. Look for patterns in user behavior and common pain points.
7. Report Findings: Document the results of the usability test, including recommendations for improvements. Share this report with stakeholders to inform future development.

For example, if testing a mobile banking app, you might ask users to complete tasks such as transferring money, checking their balance, or setting up alerts. Observing how easily they can accomplish these tasks will provide valuable insights into the app’s usability.

What is a Test Strategy?

A test strategy is a high-level document that outlines the testing approach for a project. It serves as a roadmap for the testing process, detailing the scope, objectives, resources, schedule, and overall testing methodology. A well-defined test strategy helps ensure that all stakeholders have a clear understanding of how testing will be conducted and what is expected.

Key components of a test strategy include:

• Scope of Testing: Define what will be tested (e.g., features, functionalities) and what will not be tested.
• Testing Objectives: Outline the goals of testing, such as identifying defects, ensuring compliance, or validating performance.
• Testing Methodology: Describe the testing techniques and types of testing that will be employed (e.g., manual testing, automated testing, performance testing).
• Resources: Identify the team members involved in testing, their roles, and any tools or technologies that will be used.
• Schedule: Provide a timeline for testing activities, including milestones and deadlines.
• Risk Management: Assess potential risks associated with the project and outline strategies for mitigating them.

For instance, a test strategy for a new web application might specify that functional testing will be conducted using manual testing techniques, while performance testing will be automated. It would also outline the testing schedule, indicating when each phase of testing will occur and who is responsible for each task.

How Do You Handle Regression Testing?

Regression testing is a type of software testing that ensures that recent changes or enhancements to the application have not adversely affected existing functionalities. It is a critical part of the software development lifecycle, especially in agile environments where changes are frequent.

To handle regression testing effectively, follow these steps:

1. Identify Test Cases: Review existing test cases and identify which ones are relevant to the changes made. This may include functional tests, integration tests, and user acceptance tests.
2. Prioritize Test Cases: Not all test cases need to be executed for every release. Prioritize test cases based on risk, usage frequency, and critical functionalities.
3. Automate Where Possible: Consider automating regression tests to save time and resources. Automated tests can be run quickly and repeatedly, making them ideal for regression testing.
4. Execute Tests: Run the selected test cases against the updated application. Document any defects found during testing.
5. Review and Update Test Cases: After executing the tests, review the results and update the test cases as necessary to reflect any changes in functionality.
6. Communicate Results: Share the results of regression testing with the development team and stakeholders, highlighting any critical issues that need to be addressed.

For example, if a new feature is added to a project management tool, regression testing would involve running tests on existing features like task creation, user permissions, and reporting to ensure that they still function correctly after the new feature is implemented.

Technical Manual Testing Interview Questions

What is a Requirement Traceability Matrix (RTM)?

The Requirement Traceability Matrix (RTM) is a crucial document in the software development lifecycle that helps ensure all requirements defined for a system are tested in the test protocols. It serves as a bridge between the requirements and the testing phases, allowing teams to track the progress of requirements through the testing process.

RTM typically includes the following components:

• Requirement ID: A unique identifier for each requirement.
• Requirement Description: A brief description of the requirement.
• Test Case ID: A unique identifier for each test case that validates the requirement.
• Test Case Description: A brief description of what the test case does.
• Status: The current status of the test case (e.g., Pass, Fail, Not Executed).

For example, if a requirement states that “Users must be able to log in using their email and password,” the RTM would link this requirement to specific test cases that verify this functionality, such as “TC001: Verify login with valid credentials” and “TC002: Verify login with invalid credentials.”

Using an RTM helps teams ensure comprehensive test coverage, identify gaps in testing, and facilitate communication among stakeholders. It is particularly useful in projects with numerous requirements and complex functionalities.

Explain the Concept of Defect Density.

Defect Density is a metric used in software testing to measure the number of defects confirmed in a software component relative to the size of that component. It is typically expressed as the number of defects per unit size, such as per thousand lines of code (KLOC) or per function point.

The formula for calculating defect density is:

Defect Density = (Number of Defects) / (Size of the Software Component)

For instance, if a software module has 5 defects and consists of 1000 lines of code, the defect density would be:

Defect Density = 5 / 1 = 5 defects per KLOC

Defect density is a valuable metric for assessing the quality of the software and the effectiveness of the testing process. A higher defect density may indicate poor code quality or insufficient testing, while a lower defect density suggests a more stable and reliable product. However, it is essential to consider defect density in context, as different types of software and development practices can yield varying results.

What is a Test Harness?

A Test Harness is a collection of software and test data configured to test a program unit by running it under varying conditions and monitoring its behavior and outputs. It provides the necessary environment to execute tests and can include test scripts, test data, and the necessary tools to automate the testing process.

Key components of a test harness include:

• Test Scripts: Automated scripts that execute the test cases.
• Test Data: Input data used during testing to validate the functionality.
• Test Execution Engine: The framework that runs the test scripts and manages the execution process.
• Reporting Tools: Tools that generate reports on test results, including pass/fail status and defect logs.

For example, in a web application testing scenario, a test harness might include scripts that simulate user interactions, such as logging in, navigating through pages, and submitting forms. The harness would capture the application’s responses and compare them against expected outcomes to identify any discrepancies.

Using a test harness can significantly improve testing efficiency, especially in regression testing, where the same tests need to be executed repeatedly. It also helps in maintaining consistency in test execution and results reporting.

How Do You Perform Database Testing Manually?

Database testing is a critical aspect of software testing that focuses on verifying the integrity, accuracy, and reliability of the data stored in a database. Manual database testing involves several steps to ensure that the database functions as expected. Here’s how to perform it:
