Repro steps.

• ng new ngTest
• cd ngTest
• yarn
• Create folder typings in src
• Create file common.d.ts in src/typings with content:

declare module Common {
  export interface IAction {
    type: string;
  }
}

• In app.component.ts add a constructor

constructor() {
  const action: Common.IAction = { type: 'test' };
}

• Running ng test once works
• Saving app.component.ts (retriggering ng test) fails to find type definition, but test succeeds

The log given by the failure.

ERROR in /home/tobias/projects/external/ngTest/src/app/app.component.ts (12,19): Cannot find namespace 'Common'.)
Chrome 56.0.2924 (Linux 0.0.0): Executed 3 of 3 SUCCESS (0.222 secs / 0.215 secs)

After fiddling some more with this I notice that the typing error actually stops the rebuild, and runs the test again with the previous build.

This make it look like the test succeeds even though the typing fails, but it's just showing a result from a previous build.

To be able to run tests that actually tests my current code, I need to use ng test --single-run true.
