grunt-ptor

Run Protractor e2e tests.

Motivation

Other plugins exist, but I just wanted something simple that passed the required options through to the Protractor command.

Getting Started

This plugin requires Grunt ~0.4.5.

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

$ npm install grunt-ptor --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-ptor');

Note that this plugin leaves the Selenium server management up to another tool. I use grunt-protractor-webdriver, which is then set up as a pre-requisite task to this plugin.

The "ptor" task

Overview

In your project's Gruntfile, add a section named ptor to the data object passed into grunt.initConfig().

grunt.initConfig({
  ptor: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      options: {
        // Target-specific options go here.
      }
    },
  },
});

Options

See the Protractor reference conf for the options you can use in both the Gruntfile and via the command line.

The order of precendence for options is: command line > target level > task level > Protractor conf file.

Example

grunt.initConfig({
  ptor: {
    options: {
      configFile: 'protractor.conf.js'
    },
    smoke: {
      options: {
        suites: 'smoke'
      }
    }
  }
});

$ grunt ptor --chromeOnly --params.login.user=Jane --params.login.password=1234

Tests

To run:

$ grunt test

Test notes

A child process is spawned within each test so we can execute the task from end to end. This makes method stubbing a little tricky since we are executing in a different process, so a couple of helper tasks are also used:

• pre sets up any required stubs
• post sends the required information back to the parent process.

This way we can test our expectations in the parent process.
