KPI stands for Key Performance Indicator. It’s a measurable value used to evaluate the success or effectiveness of a testing process, team, or software quality. KPIs help teams track progress, identify areas for improvement and ensure the software meets its quality goals.
Some common KPIs in software testing include:
- Test Coverage: The percentage of the code or requirements covered by tests.
- Test Case Effectiveness: Measures the percentage of defects detected by test cases.
- Defect Density: The number of defects found per module, function, or lines of code.
- Defect Detection Rate: The number of defects found during testing compared to the total defects discovered later.
- Defect Leakage: Measures the percentage of defects not caught during testing and found in production.
- Test Execution Rate: The number of test cases executed within a given time frame.
- Bug Resolution Time: The average time taken to fix identified defects.
- MTTD: The average time taken to find defects.
- MTTR: The average time taken to fix a defect once detected.
- Automation Test Coverage: Measures how much of the test suite is automated.
- Pass/Fail Rate: The ratio of test cases that pass versus those that fail.
- Escaped Defects: Number of defects found by end-users after release, highlighting gaps in testing.
