electron-mocha and istanbul/isparta

Any ideas on how to get istanbul or isparta to generate a coverage report based on electron-mocha results. I run the following command and get the following error:

./node_modules/.bin/istanbul cover electron-mocha -- --compilers js:babel/register --recursive


  Test app menu creation
    ✓ should set isQuitMenu to true if quit is clicked


  1 passing (19ms)

No coverage information was collected, exit without writing coverage information

Basically, yes. Note that if you’re using babel already you can now just use the excellent istanbul-plugin to instrument your code. If you do this, you really only need to write out the __coverage__ object after the tests have run. (I write them out for both renderer and main thread tests, then combine them using nyc report from the command line).

Thanks everyone for sharing your discoveries when adding code coverage to your Electron applications. It helped me to get code coverage for our app which is written in TypeScript. So if you need another example on how to set it up, then this PR might be of help: https://github.com/wireapp/wire-desktop/pull/2215 💐
