[RedSparr0w]

When running npm run coverage:test:services -- --only=whateveryourtesting
you will get an error in console and the coverage test will not run:

C:\Users\Dan\Documents\GitHub\shields>npm run coverage:test:services -- --only=chrome-web-store

> gh-badges@1.3.0 coverage:test:services C:\Users\Dan\Documents\GitHub\shields
> istanbul cover _mocha service-tests/runner/cli.js --dir coverage/services -- --delay "--only=chrome-web-store"

This comment has a fix which is to provide the relative path to the _mocha JS file.

which would change these lines to be:

    "coverage:test:js": "istanbul cover node_modules/mocha/bin/_mocha '*.spec.js' 'lib/*.spec.js' --dir coverage/js",
    "coverage:test:services": "istanbul cover node_modules/mocha/bin/_mocha service-tests/runner/cli.js --dir coverage/services -- --delay",
