What testing methods do you know?

Functional testing:
- Unit testing: Testing the smallest isolated parts of code (functions, classes).
- Integration testing: Checking the interaction between different modules or components of the system.
- System testing: Testing the entire integrated system for compliance with requirements.
- Acceptance testing: Testing by end-users or business representatives to confirm it meets their needs.
Non-functional testing:
- Performance testing: Assessing system performance under load.
  - Load testing: Testing the system under expected load.
  - Stress testing: Testing the system beyond expected load to determine failure points.
  - Endurance (Soak) testing: Checking system stability during prolonged operation under load.
- Security testing: Assessing system security against threats.
- Usability testing: Checking how user-friendly the system is for end-users.
- Compatibility testing: Testing system operation across different environments (browsers, OS, devices).
- Reliability testing: Assessing the system's ability to operate without failures over a certain period.
- Maintainability testing: Evaluating how easy it is to make changes to the system.
- Portability testing: Assessing the system's ability to be transferred to another environment.
Change testing:
- Regression testing: Re-testing previously tested functionality after changes to identify new defects.
- Re-testing (Confirmation testing): Re-testing a specific defect after fixing it to confirm its resolution.
Structural testing (White-box testing): Testing internal structure and logic of code.
- Statement coverage: Covering all code statements.
- Branch coverage: Covering all branches of code logic (conditions).
- Path coverage: Covering all possible execution paths of the code.
Black-box testing:
- Boundary value analysis: Testing boundary input values.
- Equivalence partitioning: Dividing input data into equivalent classes.
- Decision table testing: Using decision tables to test combinations of conditions and actions.
- State transition testing: Testing transitions between different system states.
- Use case testing: Testing the system based on user scenarios.
Exploratory testing: Simultaneous test design, execution, and result analysis.
Risk-based testing: Prioritizing testing based on potential risks.
