appium-gulp-plugins

Custom plugins used accross appium modules

transpile plugin

Traceur compilation, sourcemaps and file renaming functionality in one plugin. .es7.js and .es6.js files will be automatically renamed to .js files. The necessary sourcemaps and traceur comments and imports are also automatically added.

usage

1/ Configure gulp as below:

var gulp = require('gulp'),
Transpiler = require('appium-gulp-plugins').Transpiler;

gulp.task('transpile', function () {
  var transpiler = new Transpiler();
  // traceur options are configurable in transpiler.traceurOpts

  return gulp.src('test/fixtures/es7/**/*.js')
    .pipe(transpiler.stream())
    .pipe(gulp.dest('build'));
});

2/ in your code you need to mark the main and mocha files as below:

• main: add // transpile:main at the beginning of the file (example here) .
• mocha: add // transpile:mocha at the beginning of the file (example here)

Regular lib files do not need any extra comments.

with gulp-mocha

Set the following env variable to skip the traceur runtime declaration.

process.env.SKIP_TRACEUR_RUNTIME = true;

watch plugin

There are some issues Gulp 3.x error handling which cause the default gulp-watch to hang. This pluging is a small hack which solves that by respawning the whole process on error. This should not be needed is gulp 4.0.

usage

var gulp = require('gulp'),
    spawnWatcher = require('./index').spawnWatcher.use(gulp);

spawnWatcher.configure('watch', ['lib/**/*.js','test/**/*.js','!test/fixtures'], function() {
  // this is the watch action
  return runSequence('test');
});

error handling

The spawn needs to catch error as soon as they happen. To do so use the spawnWatcher.handleError method, for instance:

// add error handling where needed
gulp.task('transpile', function () {
  return gulp.src('test/es7/**/*.js')
    .pipe(transpile())
    .on('error', spawnWatcher.handleError)
    .pipe(gulp.dest('build'));
});

gulp.task('test', ['transpile'] , function () {
  process.env.SKIP_TRACEUR_RUNTIME = true;
  return gulp.src('build/test/a-specs.js')
    .pipe(mocha())
    .on('error', spawnWatcher.handleError);
});

clear terminal

Terminal is cleared by default. To avoid that call:

spawnWatcher.clear(false);
