TDD with Browserify, Mocha, PhantomJS and WebDriver

  • Fast roundtrip
  • No test HTML page
  • No server
  • Selenium WebDriver & SauceLabs support
  • Code coverage with coverify
  • Code coverage with istanbul using mochify-istanbul plugin
  • Short stack traces with relative paths
  • Works with most Mocha reporters

mochify

Install

This will install Mochify in your current project and add it to the devDependencies:

npm install mochify --save-dev
  • Install Phantom.JS: npm install phantomjs -g or download from http://phantomjs.org/
  • Make sure that the phantomjs executable is in your PATH or use --phantomjs <path>

Usage

Configure "scripts" in your package.json so that your project ships with the testing infrastructure:

"devDependencies" : {
  "mochify"       : "*"
},
"scripts"         : {
  "start"         : "mochify --watch",
  "phantom"       : "mochify",
  "wd"            : "mochify --wd",
  "cover"         : "mochify --cover",
  "test"          : "npm run phantom && npm run wd && npm run cover"
}

To run from the command line, either run npm install mochify -g to have mochify available globally, or from within your project directory run:

node_modules/.bin/mochify

Default behavior

Browserifies ./test/*.js, decorated with a Mocha test runner, runs it in PhantomJS with phantomic and pass the output back to your console. Cleans up your stack traces by mapping back to the original sources and throws out all the lines from the test framework.

Run mochify --help to see all available options.

Command line options

  • --watch or -w use watchify to watch your files and run the tests on change.
  • --reporter or -R changes the Mocha reporter (see further down).
  • --grep sets the Mocha grep option.
  • --invert sets the Mocha grep invert flag.
  • --recursive include sub directories.
  • --ui or -U changes the Mocha UI. Defaults to 'bdd'.
  • --timeout or -t changes the Mocha timeout. Defaults to 2000.
  • --require or -r requires the given module.
  • --debug launches the WebKit debugger.
  • --port uses a specific port for the PhantomJS server.
  • --phantomjs uses a specific PhantomJS executable. If not specified, phantomjs is expected on the $PATH.
  • --web-security enables PhantomJS web security and forbids cross-domain XHR (default is true)
  • --cover checks code coverage with coverify.
  • --node runs test cases on node (useful with --cover).
  • --wd use min-webdriver to run the tests in multiple real browsers.
  • --url (only with --wd) runs the tests in the context of the given URL.
  • --consolify output.html generate a standalone HTML page with consolify.
  • --transform specifies a Browserify transform to add. Can be specified multiple times. Options can be passed with subargs.
  • --plugin specifies a Browserify plugin to add. Can be specified multiple times. Options can be passed with subargs.
  • --extension search for files with the extension in "require" statements.
  • --yields or -y changes the yield interval to allow pending I/O to happen.
  • --version or -v shows the Mochify version number.
  • --help or -h shows usage and all available options.

Selenium WebDriver setup

java -jar selenium-server-standalone-2.39.0.jar

Create .min-wd in your project root:

{
  "hostname"  : "localhost",
  "port"      : 4444,
  "browsers"  : [{
    "name"    : "internet explorer",
    "version" : "9"
  }, {
    "name"    : "chrome"
  }, {
    "name"    : "firefox"
  }]
}

That's it! Now mochify --wd will run your Mocha test cases in the configured browsers simultaniously. If you installed mochify without -g, you will have to run node_modules/.bin/mochify --wd.

SauceLabs setup

Export your SauceLabs credentials:

export SAUCE_USERNAME="your-user-name"
export SAUCE_ACCESS_KEY="your-access-key"

Enable SauceLabs in your .min-wd file:

{
  "sauceLabs": true
}

For more information about Selenium WebDriver and SourceLabs support can be found on the min-webdriver project page.

Reporters

Mocha reporters known to work:

  • min
  • dot (default)
  • list
  • spec
  • tap
  • json
  • doc
  • xunit
  • markdown
  • landing

Note: Consuming the output of a machine readable reporter may not work as expected with --wd.

API

var mochify = require('mochify');
 
mochify('./test/*.js', {
  reporter : 'tap',
  cover    : true
}).bundle();
  • mochify() uses default settings and runs tests in ./test/*.js
  • mochify(paths) specifies the paths, a space delimited list of globs
  • mochify(opts) configures options as described below
  • mochify(paths, opts) combines custom paths and options

All long form command line options can be used. E.g. --node can be configured as { node : true }, --reporter tab as { reporter : 'tab' } and so on.

Additional API options:

  • output a stream that receives the test output (e.g. through2)

Code coverage with Istanbul

Install the mochify-istanbul plugin:

$ npm install mochify-istanbul --save-dev

Using a package.json script that can be run with npm run cover:

"scripts" : {
  "cover" : "mochify --plugin [ mochify-istanbul --report cobertura ]"
}

Using the API:

var mochify = require('mochify');
var istanbul = require('mochify-istanbul');
 
mochify().plugin(istanbul, {
  report: ['text', 'html', 'text-summary']
}).bundle();
