1. Unit Testing

Test interactions between multiple units to ensure they integrate smoothly and identify interface issues.

2. Integration Testing

Validate the functionality of the software to ensure it meets the specified requirements.

3. Functional Testing

Re-test modified code to ensure new changes doesn't adversely affect existing functionalities.

4. Regression Testing

Assess software's speed, responsiveness, and stability under varying conditions to optimize performance.

5. Performance Testing

Identify vulnerabilities and weaknesses in the system to ensure data and user information remain protected.

6. Security Testing

Evaluate system behavior under expected and peak loads to determine its capacity limits.

7. Load Testing

Check the user-friendliness and user experience to enhance the overall usability of the application.

8. Usability Testing

Verify the entire software workflow to ensure all components work together cohesively.

9. End-to-End Testing

Ensure the software meets business requirements and is ready for deployment.

10. Acceptance Testing

An unscripted testing approach where developers explore the software to uncover hidden defects & assess user experience.
