What are the types of white box testing?

White box testing can be categorized into several types based on the focus and methodology of the testing. Here are some primary types: 1. **Unit Testing**: Involves testing individual units or components of the software in isolation. The goal is to validate that each unit functions correctly on its own. 2. **Integration Testing**: Focuses on testing the interactions between integrated units or components to ensure they work together as expected. 3. **System Testing**: Tests the complete and integrated software system to ensure it meets the specified requirements. It combines both white box and black box testing techniques. 4. **Acceptance Testing**: Verifies whether the software meets the user requirements and is ready for deployment. Although it often involves black box testing, white box techniques can be used to ensure internal functions align with acceptance criteria. 5. **Regression Testing**: Ensures that recent changes or enhancements to the code have not adversely affected existing functionality. This includes re-testing the previously passed cases to confirm no new issues have been introduced. 6. **Security Testing**: Involves checking the application for vulnerabilities and weaknesses that could be exploited. This includes testing access controls, data protection, and other security measures. 7. **Performance Testing**: Assesses how the software performs under various conditions. While it primarily involves black box testing, white box techniques may be used to analyze and optimize the internal logic affecting performance. 8. **Mutation Testing**: Involves modifying the code (mutations) and checking if the existing test cases can detect these changes. This technique evaluates the effectiveness of the test suite. 9. **Control Flow Testing**: Focuses on the execution paths within the code. It ensures that all control paths, loops, and branches are tested. 10. **Data Flow Testing**: Concentrates on the flow of data through the software, validating that data is correctly processed and maintained across different points. These types ensure that various aspects of the software’s internal structure and logic are thoroughly tested. read less
