Fundamentals of Software Testing

What are the main types of software testing?

• User interface testing

• Code review testing

• Documentation testing

• Unit testing, integration testing, system testing, acceptance testing, performance testing, regression testing.

Define unit testing and its purpose.

• Unit testing is a method of testing individual components of software to ensure they function correctly.

• Unit testing is used to evaluate the performance of the software under load.

• Unit testing focuses on user interface testing rather than code components.

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

What is the difference between manual and automated testing?

• Manual testing can be done without any tools.

• Automated testing requires no initial setup.

• Manual testing is faster than automated testing.

• Manual testing is performed by humans, while automated testing uses tools and scripts.

Explain the concept of black-box testing.

• Black-box testing is a method of software testing that evaluates the functionality of an application without knowledge of its internal code structure.

• Black-box testing focuses solely on performance metrics.

• Black-box testing is only applicable to hardware testing.

• Black-box testing requires access to the source code.

What is a test case and what are its components?

• A test case is a set of conditions to test a software application, consisting of components like Test Case ID, Description, Preconditions, Test Steps, Expected Result, and Actual Result.

• A test case is a summary of the software development process.

• A test case is a list of all software bugs found during testing.

• A test case is a document that outlines the software architecture.

Describe the defect life cycle stages.

• Creation, Assignment, Verification, Closure, Reopen

• Detection, Analysis, Reporting, Fixing, Testing, Closure

• The defect life cycle stages are Identification, Classification, Assignment, Resolution, Verification, Closure, and Reopen.

• Identification, Resolution, Testing, Documentation, Review

What is regression testing and why is it important?

• Regression testing is used to create new features in software.

• Regression testing is only necessary for major releases.

• Regression testing is important because it helps identify bugs introduced by new code changes, ensures the stability of the software, and maintains the quality of the product over time.

• Regression testing is irrelevant for small code changes.

List some common automated testing tools.

• JUnit5

• Maven

• Postman

• Selenium, JUnit, TestNG, Cypress

What is performance testing and its objectives?

• Performance testing evaluates a system's responsiveness and stability under load, aiming to identify bottlenecks and ensure optimal performance.

• Performance testing measures user satisfaction and feedback.

• Performance testing is only concerned with software installation processes.

• Performance testing focuses solely on security vulnerabilities.

Explain load testing and stress testing.

• Load testing is performed only once; stress testing is done during every release.

• Load testing is only for web applications; stress testing is unnecessary.

• Load testing measures system performance under expected loads; stress testing evaluates system behavior under extreme conditions.

• Load testing checks for security vulnerabilities; stress testing measures user satisfaction.
