Software testing is a vast field with numerous techniques and methodologies to ensure that software meets its specifications and works correctly. Here’s a list of common types of software testing:



  1. Functional Testing: Evaluates the system’s functionality against the requirements. Common types include:

    • Unit Testing: Test individual units or components of the software.
    • Integration Testing: Test interfaces between components or systems.
    • System Testing: Test the complete integrated system.
    • Acceptance Testing: Check if the software meets the acceptance criteria, often carried out by the client or end-users.
  2. Non-functional Testing: Tests the non-functional aspects like performance, usability, etc. Types include:

    • Performance Testing: Evaluates the system’s performance. This can further be divided into:
      • Load Testing
      • Stress Testing
      • Volume Testing
      • Scalability Testing
    • Usability Testing: Evaluates the software’s user-friendliness.
    • Security Testing: Checks for vulnerabilities, threats, and risks.
    • Compatibility Testing: Ensures software works in different environments – browsers, OS, etc.
    • Reliability Testing: Measures software stability.
    • Recovery Testing: Checks the software’s ability to recover from failures.
  3. Regression Testing: Ensures that recent changes haven’t adversely affected existing features.

  4. Smoke Testing (or Sanity Testing): A preliminary test to check the basic functionalities of an application.

  5. Exploratory Testing: Testers explore the application to identify defects.

  6. Ad-hoc Testing: Without any specific test case or plan in mind.

  7. Alpha Testing: Conducted by the in-house developer team before the product is released to select external users.

  8. Beta Testing: After alpha testing, it’s released to a select group of external users.

  9. Black Box Testing: Tests the software without any knowledge of its inner workings.

  10. White Box Testing: Tests the software with knowledge of its inner code and logic.

  11. Grey Box Testing: Combination of both black box and white box testing.

  12. Database Testing: Checks the integrity of the database.

  13. Boundary Testing: Test the software using the boundary values of the input domain.

  14. Error Handling Testing: Ensures that errors are handled appropriately.

  15. Mobile Testing: Tests software on mobile devices.

  16. API Testing: Directly tests the APIs for functionality, reliability, etc.

  17. Monkey Testing: Random testing with no specific use-case in mind.

  18. User Acceptance Testing (UAT): Final phase where actual users test the software to see if it’s ready for release.

  19. Localization/Globalization Testing: Checks the software’s localization for a particular region or culture and its adaptability globally.

  20. Parallel/Audit Testing: Compare results of two different systems.

  21. Static vs. Dynamic Testing: While static testing evaluates the software’s documentation and code without running the program, dynamic testing checks the software by executing it.

  22. Installation Testing: Validates whether the software installs correctly.

  23. Configuration Testing: Checks software with multiple configurations.

  24. Conformance (or Compliance) Testing: Ensures the software adheres to standards.

  25. Operational Testing: Evaluates the operational readiness of a software application.

  26. Accessibility Testing: Ensures software and applications are accessible by people with disabilities.

These are just some of the main types of software testing. Depending on the nature and requirements of a software product, testers might employ a combination of multiple testing types and methodologies.
