Software Testing Fundamentals

What is the primary purpose of software testing?

• To enhance software performance.

• To identify defects and ensure software quality.

• To reduce software development time.

• To increase software costs.

Define unit testing and its significance.

• Unit testing is only for large software projects.

• Unit testing is a method for testing the entire application at once.

• Unit testing is unnecessary if the software is well-documented.

• Unit testing is a method of testing individual components of software to ensure they function correctly, and it is significant for early bug detection, facilitating changes, and enhancing code quality.

What is the difference between functional and non-functional testing?

• Functional testing measures the system's performance under load.

• Non-functional testing is concerned with specific features of the system.

• Functional testing focuses on what the system does, while non-functional testing focuses on how the system performs.

• Functional testing is only about user interface design.

Explain the concept of regression testing.

• Regression testing is used to create new features.

• Regression testing is performed to verify that new code changes do not disrupt existing features.

• Regression testing is only done for performance improvements.

• Regression testing is a method for user acceptance testing.

What are the main types of software testing?

• User documentation

• Code review

• Unit testing, Integration testing, System testing, Acceptance testing, Functional testing, Non-functional testing, Regression testing, Performance testing.

• Software deployment

What is a test case and what does it typically include?

• A test case typically includes a test description, input data, execution steps, expected results, and actual results.

• A test case is a document that outlines team roles.

• A test case is a summary of the entire project.

• A test case only includes the expected results.

Describe the role of automated testing in software development.

• Automated testing improves code quality, reduces manual testing, and accelerates feedback in software development.

• Automated testing slows down the development process.

• Automated testing is only useful for large projects.

• Automated testing eliminates the need for any testing.

What is the purpose of a bug report?

• To suggest new features for the software.

• To list all the software functionalities.

• The purpose of a bug report is to document and communicate software defects for resolution.

• To provide user feedback on software features.

Explain the difference between black-box and white-box testing.

• Black-box testing tests functionality without code knowledge; white-box testing tests internal code structure.

• Black-box testing requires knowledge of the internal code structure; white-box testing does not.

• Black-box testing is only for performance testing; white-box testing is for security testing.

• Black-box testing focuses on user experience; white-box testing focuses on documentation.

What is the importance of performance testing in software applications?

• Performance testing is important for validating application responsiveness, stability, and scalability under various load conditions.

• Performance testing is only necessary for large applications.

• Performance testing is irrelevant for mobile applications.

• Performance testing focuses solely on security vulnerabilities.
