Run client-side Mocha tests in Electron (This is a fork of the original gulp-electron-mocha module: https://github.com/nodaguti/gulp-electron-mocha)

This is a simple wrapper for electron-mocha.

The implementations are mostly inspired by gulp-mocha-phantomjs.

npm install --save-dev gulp-electron-mocha

Note that you don't have to install either electron-mocha or electron-prebuilt globally (i.e. with npm i -g). All dependencies are resolved automatically.

import gulp from 'gulp';
import electronMocha from 'gulp-electron-mocha';

gulp.task('test', () =>
  gulp.src('./test', { read: false })
    .pipe(electronMocha())
);

Please be aware that you should write gulp.src('./test'), not gulp.src('./test/*.js'), because electron-mocha requires a directory to test.

You can also find working tests in test/ to learn how to make Gulp tasks and client-side Mocha tests with gulp-electron-mocha.

The electronMocha property of the optional argument to electronMocha() is passed to electron-mocha.

Please see electron-mocha's docs to learn what parameters are available.

gulp-electron-mocha uses object-to-spawn-args to convert from JavaScript object to command-line argument string.

import gulp from 'gulp';
import electronMocha from 'gulp-electron-mocha';

gulp.task('test', () =>
  gulp.src('./test', { read: false })
    .pipe(electronMocha({
      electronMocha: {
        renderer: true,
        'no-timeout': true,
      },
    }))
);

gulp-electron-mocha can pass --compilers option to Mocha. So just specify babel-core/register to --compilers.

gulp.src('./test', { read: false })
  .pipe(electronMocha({
    electronMocha: {
      renderer: true,
      compilers: 'js:babel-core/register',
      'no-timeout': true,
    },
  }))

• electronPath

  Type	Default
  string	undefined

  A path to Electron in which tests are executed. If not specified, gulp-electron-mocha uses Electron in node_modules/ by default.

• silent

  Type	Default
  bool	false

  Don't throw an error even if one of the tests is failed.

• suppressStdout

  Type	Default
  bool	false

  Don't redirect electron-mocha's stdout to the console.

• suppressStderr

  Type	Default
  bool	false

  Don't redirect electron-mocha's stderr to the console.

• electronMocha

  Type	Default
  Object	{}

  Options to be passed to electron-mocha. See electron-mocha's docs for more details.

  The value will be converted to command-line argument string with object-to-spawn-args.

  For example, if you want to pass --no-timeout --renderer -s 200 --compilers js:babel-core/register, specify:

  electronMocha: {
    'no-timeout': true,
    renderer: true,
    s: 200,
    compilers: 'js:babel-core/register',
  }

This plugin emits events named electronMochaStdoutData, electronMochaStdoutEnd, electronMochaStderrData, electronMochaStderrEnd, electronMochaError, and electronMochaExit, which are implemented by the following code:

electronMocha.stdout.on('data', stream.emit.bind(stream, 'electronMochaStdoutData'));
electronMocha.stdout.on('end', stream.emit.bind(stream, 'electronMochaStdoutEnd'));

electronMocha.stderr.on('data', stream.emit.bind(stream, 'electronMochaStderrData'));
electronMocha.stderr.on('end', stream.emit.bind(stream, 'electronMochaStderrEnd'));

electronMocha.on('error', stream.emit.bind(stream, 'electronMochaError'));
electronMocha.on('exit', stream.emit.bind(stream, 'electronMochaExit'));
