Reinstate testing docs for Karma #3244

Closed eriknygren closed 2 years ago

eriknygren commented 2 years ago

Found these docs very useful to get going with Karma unit tests in Webpacker 5. So I ported them over from the last version's docs to match what I had to do to get it working in Webpacker 6.

The docs no longer involve Typescript setup, as I don't use it on my webpacker project, but hopefully this will serve as a good starting point for others.

I think the doc could be hosted on a blog.

I posted here as an example:

https://forum.shakacode.com/t/karma-setup-for-webpacker-v5/2227

I don't like this in the repo because:

  1. We have to maintain this.
  2. Jest is reportedly preferable over Karma for speed.

We can reopen if others feel differently.

Ok. Running a unit test suite feels like a use-case common enough to the point it's worth maintaining docs for in my opinion. But I understand if the consensus is that Karma is not the go-to for Webpacker 6.
