Problem with silent fail and using coveralls + mocha-webpack

[kristianmandrup]

I have this setup

"scripts:" {
    "mocha:lint:test": "npm run lint & mocha-webpack --opts test/config/mocha/mocha-webpack.opts",
    "mocha:test": "mocha-webpack --opts test/config/mocha/mocha-webpack.opts",
    "mocha:test:watch": "mocha-webpack --opts test/config/mocha/mocha-webpack.opts --watch",
    "test": "npm run mocha:test --silent",
    "coverage": "cross-env NODE_ENV=test nyc --reporter=lcov --reporter=text --cache --silent mocha-webpack --opts test/config/mocha/mocha-webpack.opts",
    "coveralls": "npm run coverage | coveralls",
    "istanbul": "npm-run istanbul cover",
    "cover:report": "npm-run plato -r -d report src",
   ...
}

First problem is that I get this stupid Exit 1 error each time.

 0 passing (14ms)
  1 failing

  1) Operator: code an instance have a name:
     AssertionError: expected { opts: 'kris' } to deeply equal true
      at Context.that.should (eval at <anonymous> (.tmp/mocha-webpack/28cf7d614cc45dc0abdbbfe10ec37561/28cf7d614cc45dc0abdbbfe10ec37561-output.js:85:1), <anonymous>:17:32)

I was successful adding silent mode here:

"test": "npm run mocha:test --silent", how can I do the same for my coverage script?

Second, when I pipe to coveralls it fails:

 cross-env NODE_ENV=test nyc --reporter=lcov --reporter=text --cache --silent mocha-webpack --opts test/config/mocha/mocha-webpack.opts | coveralls

Since it tries to parse the output from running the mocha tests via mocha-webpack.
What is the right way? To run it using mocha and sidestepping webpack!?

Thanks ;)

I get the same problems with this setup:

    "coverage": "cross-env NODE_ENV=test nyc --reporter=lcov --reporter=text --cache mocha src/**/*.test.js",
    "coveralls": "npm run coverage | coveralls",

Please advice :)

@kristianmandrup coveralls needs to have lcov format pushed at it, I recommend using this approach instead:

    "coverage": "cross-env NODE_ENV=test nyc --reporter=text --cache mocha src/**/*.test.js",
    "coveralls": "nyc report --reporter=text-lcov | coveralls",

As long as you run coverage before running coveralls, nyc will have cached the coverage data; and will be able to run a text-lcov report that you can pipe to coveralls.

Feel free to reopen this issue if this doesn't do the trick for you.
