● Improved code quality and maintainability.
2. Integration Testing
Integration testing focuses on different application units or module
interactions. The objective is to ensure that these integrated components
work together seamlessly. Integration tests are critical for identifying issues
that may arise when individual units are combined, such as interface
mismatches, data flow problems, and communication errors.
Benefits:
● Verification of module interfaces.

5. ● Detection of integration issues early.
● Ensured proper data flow between components.
3. Functional Testing
Functional testing verifies that the software behaves according to the
specified requirements. It focuses on testing the user interface, APIs,
databases, security, and overall application functionality. Functional tests are
designed to simulate real user scenarios and validate that the application
performs the intended tasks correctly.
Benefits:
● Validation of software functionality.
● Ensured compliance with business requirements.
● Detection of critical functional issues.
4. Regression Testing
Regression testing ensures that new code changes do not adversely affect
the application's existing functionality. Automated regression tests are
essential for maintaining software stability as they quickly identify any
unintended side effects of recent modifications. This type of testing is
particularly valuable in agile development environments, where frequent
changes are common.
