Stopping Scripts with Code Coverage Thresholds in Angular

When developing Angular applications, maintaining high code quality is crucial. One way to ensure quality is by utilizing code coverage tools that identify untested parts of your codebase. However, a common issue developers face is that their scripts continue to run even if the code coverage thresholds are not met. In this post, we will explore how to address this problem effectively in your Angular project.

The Problem

Your goal is for the script to halt when any tests fail to meet the specified coverage thresholds, but it's not happening. So, what went wrong?

The Solution

Step-by-Step Instructions

Confirm Coverage Thresholds Are Set Properly: Double-check that the thresholds you set for code coverage in the coverageIstanbulReporter are as desired (e.g., 100% for all categories like statements, lines, branches, and functions).

Run Your Script Again: Once you’ve made these changes, run your original script command (fin). If any of the tests fail to meet the specified coverage thresholds, the script should now terminate, allowing you to address the issue before proceeding with the rest of your development process.

Conclusion

By incorporating the coverage-istanbul reporter into your Karma configuration, you can effectively enforce code coverage thresholds in your Angular project's workflow. This process not only optimizes your script execution but also ensures higher quality in your codebase by preventing the continuation of processes when coverage expectations are not met.

By doing this, your Angular application will remain robust, and you’ll have the peace of mind knowing that your tests uphold the quality you aim for. Happy coding!
