Study Notes
Software Testing
- Software testing is a process to execute a program or application to find software bugs (defects)
Types of Testers
- Developer: performs unit testing and integration testing
- Independent tester: performs system testing and acceptance testing
Levels of Testing
- Unit testing: testing individual components
- Integration testing: testing interaction between components (component integration and system integration)
- System testing: testing the entire system and its functionality
- Acceptance testing: testing to ensure the system meets the customer's requirements
Acceptance Testing
- Done by the system user (customer)
- Ensures the testing environment is ready for the customer to test the system
- Provides feedback to correct defects and re-test
Regression Testing
- Re-tests the entire system after corrections are made
- Ensures corrections do not affect other parts of the system
Testing Techniques
- Black box testing: testing without knowing the internal structure of the system
- White box testing: testing with knowledge of the internal structure of the system
Functional and Structural Testing
- Functional testing: focuses on the functionality of the system
- Structural testing: focuses on how the programmer develops the system
Test-Driven Development
- Develops and tests simultaneously
- Benefits: code coverage, regression testing, and simplifies debugging
Verification and Validation
- Verification: ensures the software is built correctly (are we building the product in the right way?)
- Validation: ensures the software meets the user's requirements (are we building the right product?)
Errors, Defects, and Failures
- Error: an action that leads to a fault (programmer makes an error)
- Defect: a fault in the software (program does not give the expected result)
- Failure: the inability of the system to meet the user's requirements (system fails to reach user requirements)
