Add Protractor E2E test code coverage to SonarQube

Question

I'd like Protractor E2E tests to reflect my code coverage in SonarQube.

I've tried grunt-protractor-coverage npm module but it shows 100% coverage while the report file it creates is empty.

Here's the relevant part of my Gruntfile.js:

connect: {
            options: {
                port: 9000,
                hostname: 'localhost'
            },
            runtime: {
                options: {
                    base: 'instrumented/build'
                }
            }
        },
        instrument: {
            files: 'build/**/*.js',
            options: {
                lazy: true,
                basePath: "instrumented"
            }
        },
        protractor_coverage: {
            options: {
                keepAlive: true,
                noColor: false,
                coverageDir: 'coverage',
                args: {
                    baseUrl: 'http://localhost:9000'
                }
            },
            local: {
                options: {
                    configFile: './protractor-chrome-conf.js'
                }
            }
        },
        makeReport: {
            src: 'coverage/*.json',
            options: {
                type: 'lcov',
                dir: 'coverage/dir',
                print: 'detail'
            }
        } 

Any ideas?

You must first install the SonarJS code analyzer

And then this plugin can be fed with a LCOV report providing the coverage information: http://docs.sonarqube.org/display/PLUG/JavaScript+Coverage+Results+Import
