Tests: Module not found: Error: Can't resolve 'meteor/meteor'

[rgal75]

In an attempt to write a karma test in the angularcli-meteor template, I added a test case, which depends on Meteor by importing 'meteor/meteor' in a class under test. Then, if I issue $> npm run test I get Module not found: Error: Can't resolve 'meteor/meteor'

To easily reproduce the issue, modify app.component.ts by calling anything on Meteor. E.g.

...
import { Meteor } from 'meteor/meteor'
...
ngOnInit() {
    console.log(Meteor.release)
    ...
  }

and run $> npm run test

https://github.com/angular/angular-cli/issues/8086 Unfortunately this is a known issue with no solution yet. It seems that webpack does not honour externals when running tests.

[rgal75]

Having read angular/angular-cli#8086 I can see that the issue is about Uncaught ReferenceError: Mongo is not defined. I was able to overcome this by importing 'meteor-client' in test.ts.

I suspect that the issue I reported may have a different cause.

[rgal75]

It looks to me that Karma is still using AngularCli to build the tests instead of the ejected and modified webpack.config that has the

externals: [
        resolveExternals
    ]

configuration and as a result the tests cannot see the meteor/* modules. What do you think?

[darkbasic]

I'm not sure, but the Mongo error was definitely an oversight from my side.

I'm getting the same error (though main.ts now has import 'meteor-client';)

I've resolved the build error by doing npm install meteor-client

But now i'm getting:

[darkbasic]

Did you run npm run meteor-client:bundle?

[michaelb-01]

Sorry no I hand't, ignore me! It works now!

[janKir]

I'm running into the same error. Is there a solution or workaround, yet?

Edit: I experience the error Error: Module not found: Error: Can't resolve 'meteor/meteor' as described above. I also experience this issue on a fresh clone of this repo. And I'm a little confused, that it seems to work for @michaelb-01 ?!
