wtf is karma-angular?

karma-angular is a tool that removes the repetitive setup work needed to run automated tests for Angular applications. When you're testing Angular code, you normally have to manually list every Angular module file in your test configuration and make sure they load in the correct order. This package eliminates that chore by doing it automatically. Once installed, it scans your project's dependency list (the package.json file) to find any official Angular modules you've added. It then automatically loads them into your test setup in the right order. If you later add or remove an Angular module from your project, your test configuration stays the same, you don't need to touch it. This is useful for developers building Angular applications who want to write automated tests without wrestling with configuration files every time their dependencies change. For example, if you start using Angular's routing module and later add its animation module, you just install those packages as normal and the testing setup handles itself. One limitation worth noting: the automatic scanning only works with official Angular modules released by the Angular team. If you need to include something else, or if a brand-new Angular module hasn't been whitelisted yet, there's a manual override where you can specify modules by name. The project author notes this isn't the recommended approach since it defeats the purpose of the automatic dependency management, but it's there as a safety valve.
