Software Engineering - Advanced White-Box Testing Techniques
The module focuses on advanced white-box testing techniques, specifically emphasizing Condition Testing, Modified Condition/Decision Coverage (MC/DC), Path Testing, Dataflow Testing, and Mutation Testing. These techniques are crucial for ensuring thorough testing of complex software systems, especially in safety-critical environments. Each technique is designed to systematically enhance test case design and effectiveness, thereby improving the reliability and quality of software.

What we have learnt
- Condition Testing is essential for identifying errors in compound boolean expressions.
- MC/DC is the highest standard for white-box testing, emphasizing the independent influence of conditions in decision outcomes.
- Path Testing helps achieve comprehensive execution coverage through systematic identification of independent paths.
Key Concepts
- -- Condition Testing
- A white-box testing technique aimed at thoroughly verifying the behavior of logical conditions in code, ensuring that each atomic component is evaluated to both true and false.
- -- Modified Condition/Decision Coverage (MC/DC)
- A rigorous coverage criterion that requires each condition in a Boolean decision to demonstrate independent influence on the decision's outcome.
- -- Path Testing
- A white-box technique focused on executing distinct sequences of statements within a program by analyzing Control Flow Graphs (CFG) and Cyclomatic Complexity.
- -- Dataflow Testing
- A technique that traces the lifecycle of variables throughout a program, identifying issues related to variable definitions and usages.
- -- Mutation Testing
- A method to assess the quality of a test suite by introducing small faults (mutants) into the code and checking whether the existing tests can detect these changes.
