Types of Software Testing

Manual Testing - Manual Testing is a fundamental software testing approach where tests are executed manually by human testers without automation tools or scripts. In manual testing, testers carefully review and validate the functionality, usability, and overall quality of software applications, following predefined test cases, test plans, or user scenarios.

Automated Testing - Automated testing is a software testing approach where tests are executed automatically using specialized tools and scripts, rather than being performed manually by human testers. Automated testing helps accelerate the testing process, improve efficiency, and enhance the overall quality of software applications.

Performance Testing - Performance testing assesses the responsiveness, scalability, and stability of a software application under various load conditions. It helps identify performance bottlenecks and ensures the application can handle expected user traffic.

Regression Testing - Regression testing verifies that recent code changes have not adversely affected existing functionality. It involves retesting previously tested features to ensure they still work correctly after modifications or updates.

API Testing - API (Application Programming Interface) testing is a crucial aspect of software testing that focuses on evaluating the functionality, reliability, performance, and security of APIs. APIs serve as the bridge that allows different software systems, services, or components to communicate and interact with each other.
