What is the formula for calculating test coverage?

The formula for calculating test coverage focuses on understanding the proportion of what has been tested relative to what still remains to be tested. Specifically, this approach provides a clear perspective on the scope of testing efforts and allows teams to identify areas that require additional attention.

Using this formula means that you can effectively assess how much of the application or system has been subjected to testing. By comparing what has been tested with what is left to be tested, it gives insight into completeness and potential risk areas, ensuring a thorough examination of the product.

This context emphasizes the importance of understanding the entire scope of testing rather than just focusing on the results of tests already completed. It facilitates better planning and resource allocation for future testing endeavors.
