Condition Coverage is a software testing metric that evaluates system behaviour by ensuring that each individual logical condition within a decision point is tested for all possible outcomes (true and false). This helps verify that every condition in the code has been exercised, regardless of the overall decision’s outcome. Key aspects include:
Focus:
- Individual Boolean expressions
- All possible outcomes of conditions
Process:
- Identify all conditions in code
- Create tests for true and false outcomes
- Execute tests and measure coverage
Calculation:
- (Executed condition outcomes / Total condition outcomes) * 100
Benefits:
- Thorough testing of decision logic
- Identifies untested condition outcomes
Limitations:
- Does not guarantee all combinations are tested
- May require many test cases for complex conditions
Condition coverage ensures thorough testing of individual logical conditions.
