![]() To achieve high coverage and low risk, make sure that new and refactored classes gets 100% covered by tests and that the application and test code contains as many checks/assertions as possible. ![]() These are indicative thresholds and in practice the more the better. ![]() This quality gate defines a warn threshold (80%) and a fail threshold (70%). The important part is that a test must fail explicitly when a check gets unvalidated during the test execution. These checks can be done both in test code, and in application code through assertions. But coverage is not enough the team needs to ensure that results are checked at test-time. A program with high code coverage, measured as a percentage, has had more of its source code executed during testing which suggests it has a lower chance of containing undetected software bugs compared to a program with low code coverage.Ĭode coverage is certainly the most important quality code metric. Code coverage is a measure used to describe the degree to which the source code of a program is tested by a particular test suite. ![]()
