In this lesson, you will learn about the differences between manual and automated testing in the field of quality assurance.

• Manual testing requires testers to manually execute test cases without automation tools.
• Automated testing uses software tools to automate the test execution process.

Each approach has its pros and cons, and it is important to understand when to use manual or automated testing. Manual testing is best for exploratory, ad-hoc, and user experience testing, where human judgment is essential. Automated testing is ideal for repetitive tasks, regression testing, and performance testing, focusing on speed and accuracy. By combining both approaches, QA professionals can develop a balanced testing strategy for efficient and high-quality testing.

When it comes to software testing, two main approaches are crucial: Black box testing and White box testing.

• Black box testing focuses on system functionality without considering internal code.
• White box testing involves examining the internal structure and code of the software.

Both methods are essential for ensuring software quality and reliability. Black box testing is beneficial for testing user interfaces and meeting specified requirements. White box testing helps optimize performance and identify logic or structural issues. Combining both approaches enables QA professionals to thoroughly test software from different perspectives, ensuring high-quality results.

Functional testing evaluates the functional requirements of a system, focusing on features and functionalities.

• It ensures that the software behaves as expected and meets end-user requirements.
• By mastering functional testing, QA professionals can ensure software quality and reliability.

Regression Testing is a critical part of software testing, involving rerunning tests on an application post-code changes to ensure no new bugs or faults have been introduced.

• It verifies existing functionalities post-modifications to catch unintended consequences.
• Regression testing helps in maintaining software quality and mitigating risks associated with updates and releases.
