Continue reading →: Code Coverage (Python / DevOps)Testing is important, especially in Continuous Integration / Continuous Deployment (CI/CD) environments, as it gives some reassurance that a code commit has not broken anything. But what happens if you are unsure how much of your project is covered by tests? Code Coverage Code coverage monitors tests as they run…
