Nx: Run jest within intellij

Prerequisites

• [x] I am running the latest version

• [x] I checked to make sure that this issue has not already been filed
• [ ] I'm reporting the issue to the correct repository (not related to Angular, AngularCLI or any dependency)

I am not sure if this is an Nx related issue. I am using another builder (https://www.npmjs.com/package/@angular-builders/jest) in a diferent project where everything works fine, though.

Expected Behavior

When creating a fresh Nx workspace with angular and jest I expect to be able to run any jest test from within intellij IDEA (I use the ultimate edition 2019.2).

Current Behavior

An exception occurs:

An unhandled exception occurred: reporters.find is not a function
See "/private/var/folders/dn/6yw0_6l52pb_zsjqss035h1h0000gn/T/ng-TfsdqI/angular-errors.log" for further details.

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. clone https://github.com/sroettering/jest-intellij-demo which contains a fresh nx workspace with angular and jest
2. open the project with intellij IDEA
3. Edit the jest run configuration template to use @angular/cli as jest package
   
4. open any .spec.ts file and try to run a test by clicking on the play button to the left (or press ctrl + shift + r)

There is a PR already for that #1467

[sroettering]

Well then I hope @dopsonbr resolves the conflicts soon.

[twittwer]

I'm having the same problem, can I help in some way?

[sroettering]

I already opened PR #1657 which basically resolves the conflicts from #1467 and fixes the tests.

[iangregsondev]

Yep, this above PR fixes issues - i tested it BUT its not now possible to run just "ONE" test, I have raised an issue here on github.

Trying to run just "one" test, actually runs them all.

[sroettering]

In your issue you say you used nx 8.4.4 which was released 5 days ago but my PR was only merged 15 hours ago. Are you sure that my PR would not fix your issue as well?

[iangregsondev]

8.4.4 was released 11 hours ago, and it includes your fix as far as i can see..

Actually - it is working a lot better, you can run tests now - and before you could not - but as I say, you can't run individual tests.

[sroettering]

ok my fault. then #1693 needs to be solved as well. I will close this issue as it is now possible to run the tests in intellij
