Deep Dive Into Each Testing Level

Understanding when and how to apply each level of testing is crucial for building a robust QA strategy.

Unit Testing

The foundation of quality - testing individual components in isolation. Unit testing validates the smallest testable parts of your application, ensuring each function, method, or class works correctly.

80%

Code Coverage Target

Integration Testing

Verifying components work together seamlessly. Integration testing ensures different modules or services work correctly when combined, catching interface defects and data flow issues.

100%

API Coverage

System Testing

End-to-end validation of complete system behavior. System testing evaluates the complete and integrated software system to verify it meets specified requirements and quality standards.

95%

Requirement Coverage

Acceptance Testing

Validating business requirements and user satisfaction. Acceptance testing confirms the system meets business requirements and is ready for delivery, focusing on user workflows.
