Description

Karma was deprecated a while ago (Last release: Mid 2024), see README.md of the project.

No more bug fixes or features will be applied, if something breaks in the future, it won't be fixed. Small citation from the README:

The web testing space has evolved significantly in the 10+ years since Karma's creation. The web landscape looks very different today and new patterns and tools have emerged in the ecosystem. New test runners offer more performant alternatives, and Karma no longer provides clear unique value.

I would vote for Web Test Runner as this is natively Supported by Angular since v17+
