What does Code Coverage indicate?

Code Coverage is a metric that measures the extent to which the source code of a program is tested by automated tests. Specifically, it indicates the percentage of the code that is executed while running the test suite, allowing teams to identify which parts of the application have been tested and which parts remain untested. High code coverage suggests that a significant portion of the codebase is exercised by tests, enhancing the likelihood of catching bugs and ensuring that functionality works as intended.

This metric assists teams in assessing their testing efforts, identifying untested paths, and improving the overall quality of their software. It serves as a valuable tool in the continuous integration and delivery process, providing insights into possible areas of risk.

Other options, such as those relating to documentation quality, the status of code in production, or adherence to coding standards, do not directly relate to the measurement of how much of the codebase is validated through testing. These are separate considerations that contribute to the overall quality and maintainability of software but do not specifically focus on how much code is executed during testing.
