Support code-coverage instrumentation about inject-loader HOT 2 OPEN

@mixer2 Hey there — yep, working around Istanbul (coverage in general) is pretty tricky. It’s something I’d love to support but have been unable to find the time to explore how (and if) it can be done. Sorry for the inconvenience.

from inject-loader.

@mixer2, @plasticine, the same in my project. We are using: Karma + Webpack + Istanbul Instrumenter Loader + coverageInstunbulReporter.

We are facing a pretty similar issue. Lets say that we have:

import something from './something'.

const doSomething = () => {
  const a = 50;
  const b = a + 100;
  something(b);
}

export default doSomething;

Test spec would be:

import somethingInjector from 'inject-loader!./something';

describe('something', () => {
  it('should do something', () => {
    const iSomething  = somethingInjector(
      './something': () => console.log('mocked'),
    ).default;

    iSomething();
  })
});

The issue is that coverage report shows that original doSomething() function is completely uncovered.
