Need help with typescript project references

[Rodolfo Roza Miranda]

Hello,

I'm trying to add tests to a module that has a Typescript project reference but I can't get the configuration right.

Here is my branch: https://github.com/rozamirandar/karma-typescript/tree/typescript-project-references

I created a new folder called typescript-project-reference under examples.

This folder has two typescript projects:

• shared
• angular2 (copied from examples)

In the angular2 project, I configured karma-typescript to use the tsconfig.spec.json file that references the shared project:

"references": [ { "path": "../shared" } ]

When I run the tests I get the error:

▶ npm run test

> karma-typescript-examples-angular2@5.4.0 test /home/rodolfo/dev/angular/karma-typescript/examples/typescript-project-reference/angular2
> karma start
