Automatically run client-side mocha specs via grunt/mocha/PhantomJS and support tracking code coverage with istanbul.

This is a very slight modification of grunt-mocha which only adds the capability to extract istanbul coverage data, so see grunt-mocha for usage and options.

At this time, only the extraction capability is provided, so it is still dependent on the user to instrument the source files ahead of time with istanbul in order to actually have coverage data tracked when the tests are run.

See grunt-mocha for all additional options that it supports.

The options for this are specified in the coverage object.

Type: String Default: undefined

The folder to write a coverage.json file to, defaults to no report being generated.

Type: String default: undefined

Destination folder to write an HTML report to, defaults to no report being generated.

Type: String default: undefined

Destination folder to write a cobertura-coverage.xml file to, defaults to no report being generated.

Type: String default: undefined

Destination folder to write a lcov.info file to, defaults to no report being generated.

Type: String default: undefined

Destination folder to write a clover.xml file to, defaults to no report being generated.

Example:

mocha: {
  test: {
    files: ['tests/**/*.html'],
    options: {
      coverage: {
        htmlReport: 'coverage/html'
      }
    }
  },
},

• Add option to instrument the source files on the fly with istanbul so that pre-instrumenting with another task is no longer required.
