Coverage for test execution

I’m submitting a bug report

• Library Version: 0.19

Please tell us about your environment:

• Operating System: Windows7
• Node Version: 6.3.1
• NPM Version: 3.10.5
• Browser: Chrome | PhantomJs
• Language: TypeScript

Current behavior: Perform the command au new --here , create the new project, and try to execute the test included, it ran with out issues, but then I feel keen to know the coverage of that test, I configure karma to generate coverage:

"use strict";
const path = require('path');
const project = require('./aurelia_project/aurelia.json');
const tsconfig = require('./tsconfig.json');

let testSrc = [
  { pattern: project.unitTestRunner.source, included: false },
  'test/unit/setup.js',
  'test/aurelia-karma.js'
];

let output = project.platform.output;
let appSrc = project.build.bundles.map(x => path.join(output, x.name));
let entryIndex = appSrc.indexOf(path.join(output, project.build.loader.configTarget));
let entryBundle = appSrc.splice(entryIndex, 1)[0];
let files = [entryBundle].concat(testSrc).concat(appSrc);
console.log(files);

module.exports = function(config) {
  config.set({
    basePath: './',
    frameworks: [project.testFramework.id],
    files: files,
    exclude: [],
    preprocessors: {
      [project.unitTestRunner.source]: [project.transpiler.id],
        'src/**/*.js':['coverage']
    },
    typescriptPreprocessor: {
      typescript: require('typescript'),
      options: tsconfig.compilerOptions
    },

    reporters: ['progress','coverage'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['PhantomJS'],
    singleRun: false,

    coverageReporter: {
        reporters: [
            { type: 'json', subdir: '.', file: 'coverage-final.json', dir: 'coverage/' },
            {
                type: 'lcov', subdir: '.', dir: 'coverage/'
            }
        ]
    },

    plugins: [
                'karma-jasmine',
                'karma-coverage',
                'karma-phantomjs-launcher',
    ],   

  });
};

Neither running the test from Karma Start command nor au test, the run successfully. I got:

Expected/desired behavior:

• What is the expected behavior?

the tests run and generates the coverage info

It looks like you are missing a plugin like this one to make it work.

Using ES6, I am able to get coverage on the generated files in dist with this karma file. It is not optimum, I’d prefer to have the coverage of the source code instead.

I also managed to get coverage on the source with karma-remap-istanbul which uses source maps to generate the report on the sources. However, I don’t have colors and I get the reports per file in the source folder which is annoying in my opinion. You can view the associated karma file here.

I tried to configure karma to use requirejs and babel to use directly the source files without success so far. You can look at my non working karma conf here.

I think it would be a huge plus to be able to configure code coverage for the source (and not the transpiled files) with the cli.

Thanks. I was seeing that happen, and wasn’t sure I was missing something. I worked around it by using a different configuration when running coverage and when building for the final output.
