Description: Test coverage is a metric that indicates the percentage of source code that has been executed during automated testing. This measure is crucial in the context of a continuous integration pipeline, as it allows developers to assess the effectiveness of their tests and the quality of the software. High test coverage suggests that a large portion of the code has been validated, which can reduce the likelihood of errors in production. However, it is important to note that high coverage does not guarantee the absence of errors, as there may be cases not covered by the tests. Test coverage can be measured in various ways, including line coverage, branch coverage, and function coverage, each providing different perspectives on how thorough the tests are. In a continuous integration environment, where code is integrated and tested frequently, maintaining good test coverage is essential to ensure that changes do not introduce new errors and that the software remains in a functional state. Additionally, test coverage can be used as an indicator for code quality, helping developers identify areas that need attention or that could benefit from increased testing focus.
