Repro steps

Run karma start karma.conf.js

Observed behavior

s\angular_devkit\build_angular\src\angular-cli-files\plugins\karma.ts:53
    throw new Error(`The '@angular-devkit/build-angular/plugins/karma' karma plugin is meant to` +
          ^
Error: The '@angular-devkit/build-angular/plugins/karma' karma plugin is meant to be used from within Angular CLI and will not work correctly outside of it.

Desired behavior

Be able to run test directly with karma as before version 6

This became a problem after upgrading to version 6.

This also breaks integration with the test runner in WebStorm & IDEA ... it's not possible to run tests from WebStorm any more by pressing the "green triangles" next to the test code :-(

Anybody know any alternative on running the tests? I just migrated to angular 6 as well. Now I can't run our tests. Wondering what's the suggested way to run test now? Do I need some cli configuration or something?

[krokofant]

@josephharveyangeles You can tunnel everything via the angular cli like

ng test --karma-config karma.somestuff.conf.js

For the IntelliJ (WebStorm, IDEA) integration the issue is tracked here:

Obviously this was broken by #10478 but the issue doesn't say why this is an error now..
Wouldn't the sensible thing to do, to make it a warning instead of an error before turning it into an error?
This currently prevents us from updating a project to angular 6 and i can imagine that the IntelliJ side won't be fixed in the short term..

Also, please vote on https://youtrack.jetbrains.com/issue/WEB-32653 if you are affected.

FYI, according to the jetbrains ticket, the issue will be fixed in IDEA 2018.1.4

Still broken on:

IntelliJ IDEA 2018.2 EAP (Ultimate Edition)
Build #IU-182.2371.4, built on May 15, 2018

And it is still broken on

Webstorm 2018.2 EAP
Build #WS-182.2371.25, built on May 17, 2018

@timdoes It works if you create a new run configuration. It will detect Cli and use it as Karma engine. If you run an old configuration still pointing to a global/local karma instance, it fails.

@AlexGS74 I've used your suggestion but still see "Error: Cannot find module '[myproject]\node_modules\@angular\cli\lib\server.js'". I'm om 2018.1.4

@AlexGS74 That worked. Thanks!
