Incremental Code Coverage checks with Jest
This article explores the importance of incremental code coverage checks using Jest and provides a step-by-step guide on how to run coverage reports for only the newly made changes in your codebase. With code snippets and examples, the article also explains how to define coverage thresholds and fail tests if the coverage falls below the specified threshold. By following these best practices, you can improve the quality and reliability of your code, speed up your test runs, and ensure that your code meets the same quality standards across your entire codebase.
