Custom plugins used accross appium modules

status

boilerplate plugin

This plugin sets up all the other typical plugins we use with a simple configuration object.

usage

Basically just set up the boilerplate plugin as follows:

let gulp = require('gulp'),
    boilerplate = require('appium-gulp-plugins').boilerplate.use(gulp);

boilerplate({build: "My Project Name"});

You can pass a lot of options to configure boilerplate. Here are the options along with their defaults (from lib/boilerplate.js):

let DEFAULT_OPTS = {
  files: ["*.js", "lib/**/*.js", "test/**/*.js", "!gulpfile.js"],
  transpile: true,
  transpileOut: "build",
  babelOpts: {},
  linkBabelRuntime: true,
  watch: true,
  test: true,
  testFiles: null,
  testReporter: 'nyan',
  testTimeout: 8000,
  buildName: null,
  extraPrepublishTasks: [],
  eslint: true
};

As you can see, it defaults to transpiling with Babel, running eslint running tests, and with the default task being gulp watch.

transpile plugin

Babel 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, comments and imports are also automatically added.

usage

1/ Configure gulp as below:

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

gulp.task('transpile', function () {
  let transpiler = new Transpiler();
  // babel options are configurable in transpiler.babelOpts

  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.

Type assertions

Type assertions are not yet supported, but if you use Flow you can pass in an option to the traspiler:

let transpiler = new Transpiler({flow: true});

This will leave the type annotations un-stripped. You may specify type in your code like in the following:

// The regular way
let a = function (t:string, n:number):string {return 'let's type code.'};

// Within comments
let a = function (ti/*:string*/, n/*:number*/)/*:string*/ {return 'let's type code.'};

watch plugin

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

Files in the /test directory that are named .*-specs.js are run. Tests which end in .*-e2e-specs.js are not run when watching. To run end-to-end tests, run gulp e2e-test.

usage

let 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');
});

The test function in spawnWatcher.configure should return a promise.

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 () {
  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);

notification

Native notification is enabled by default. To disable it use the --no-notif option.

collate logging and tests

Set the environment variable _FORCE_LOGS
