Test Coverage

Test coverage refers to the extent to which a software application has been tested. It measures the proportion of code, features, or scenarios that tests have examined to ensure they work correctly. High test coverage indicates that a significant part of the software has been checked, reducing the likelihood of bugs or errors slipping through. Conversely, low coverage suggests areas that may need more testing. Think of it like inspecting different parts of a machine; thorough coverage helps ensure the entire system functions properly and reliably before it’s released.
