Code coverage

Now we have covered the unit tests and integration tests in ASP.NET Core. In this section, we will discuss code coverage, which is a metric that measures the extent to which the source code of the application is covered by the test suite during testing.

Code coverage is a very important metric for software quality. If the code coverage is low, it means that there are many parts of the code that are not covered by the tests. In this case, we are not confident that the code is working as expected. Also, when we make changes or refactor the code, we are not sure whether the changes will break the existing code.

Code coverage provides insights into which parts of the code are covered (or not covered) by the tests. It can help us identify areas that may require additional testing and ensure that the code is tested thoroughly.

Code coverage plays a vital role in assessing the effectiveness and reliability of the testing process. By analyzing code coverage, we can gain...
