Test Coverage Reports are an essential feature of testing frameworks that provide developers with insights into how much of their codebase is covered by automated tests. This feature analyzes the code and generates reports that highlight which parts of the code have been tested and which have not. By identifying untested areas, developers can improve their testing strategies, ensuring that critical paths and edge cases are adequately covered. This not only enhances code quality but also reduces the risk of bugs in production, ultimately leading to more reliable software releases.
