Understanding the Different Levels of Testing in Software Testing

Software testing consists of various levels, each focusing on different aspects of the application. Unit Testing verifies individual components for correctness. Integration Testing assesses how these components work together. System Testing evaluates the complete system's compliance with requirements, while Acceptance Testing ensures the software meets user needs and expectations. These levels can be further divided into Manual Testing, where testers execute test cases by hand, and Automated Testing, which uses scripts to perform tests.
