2 years ago Most likely you have some misconfiguration in you Angular project. karma does not support Angular natively, but through an Angular plugin, so I would suggest to use Angular's support channels where you have a much better chance to get help. I would also suggest to provide a minimal runnable project as it will allow people to troubleshot it and propose a good fix instead of just guessing.
Please read https://karma-runner.github.io/4.0/intro/troubleshooting.html first.
