1. Functional Testing:
- GUI Testing: Automates the testing of graphical user interfaces (GUIs) by simulating user actions and validating the expected behavior.
2. Performance Testing:
- Load Testing: Simulates multiple concurrent users accessing a system to assess its performance under high load.
- Stress Testing: Pushes a system beyond its normal operating conditions to identify its breaking point and ensure stability.
3. API Testing:
- Contract Testing: Validates the behavior and functionality of an application programming interface (API) against its specification.
4. Unit Testing:
- Module Testing: Automates the testing of individual software modules or functions to verify their behavior in isolation.
5. Integration Testing:
- System Integration Testing: Automates the testing of multiple integrated components or modules to ensure they function correctly as a system.
6. Regression Testing:
- Smoke Testing: Conducts a rapid sanity test to ensure the basic functionality of a system after modifications or updates.
- Regression Testing: Re-executes previously passed test cases to ensure that new code changes haven't introduced any defects.
7. Data-Driven Testing:
- Automates testing with different sets of data to ensure the system behaves correctly under various conditions.
8. Keyword-Driven Testing:
- Automates testing using predefined keywords or actions that describe the steps needed to perform a test.
9. Behavior-Driven Development (BDD) and Acceptance Test-Driven Development (ATDD):
- Automates testing based on user stories or requirements written in a natural language format.
10. Cross-Browser Testing:
- Automates testing across different web browsers to ensure cross-browser compatibility.
11. Mobile Testing:
- Automates testing of mobile applications on different devices, emulators, or simulators.
12. Cloud Testing:
- Automates testing by leveraging the cloud infrastructure to provision and manage test environments.
13. Visual Testing:
- Automates the testing of user interfaces by comparing visual elements with previously approved screenshots.
14. Continuous Testing:
- Automates testing as an integral part of the software development process, enabling rapid feedback and early defect detection.
These are some of the common types of automation testing, and the choice of which types to use depends on the specific requirements of the software project and the testing objectives.
