Decision Coverage measures the extent to which decision outcomes are covered in testing. Key features include:
Definition:
- Focuses on ensuring that all possible outcomes of decision points (e.g., if statements) are executed during tests.
Calculation:
- Percentage of decision outcomes executed relative to total possible outcomes.
Importance:
- Helps identify untested paths in code logic.
- Ensures thorough testing of application behaviour under various conditions.
Tools Used:
- Code coverage analysis tools (e.g., JaCoCo, Cobertura).
Limitations:
- High decision coverage does not guarantee overall quality; other factors must also be considered.
Decision Coverage is a vital metric for assessing the completeness of tests related to conditional logic in software applications.
