grunt-resemble-cli

Grunt wrapper around the resemble-cli image diffing tool

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-resemble-cli --save-dev

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

grunt.loadNpmTasks('grunt-resemble');

The "resemble" task

Overview

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

grunt.initConfig({
  resemble: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
});

####Example Config

The resemble task supports 3 different Grunt Files Array configuration. The src files are essentially converted to paths where screenshots should be taken. By default the resemble plugin will always screenshot the root path for your application. The dest will specify the destination directory name within the screenshot root directory that will exist in the root of your application.

grunt.initConfig({
  resemble: {
    options: {
      screenshotRoot: 'optimizely-screens',
      url: 'http://0.0.0.0:8000/dist',
      gm: true

    },
    desktop: {
      options: {
        width: 1100,
      },
      src: ['dist/about', 'dist/contact', 'dist/customers', 'dist/customers/customer-stories'],
      dest: 'desktop',
    },
    tablet: {
      options: {
        width: 800,
      },
      src: ['dist/**/*.html'],
      dest: 'tablet',
    },
    mobile: {
      options: {
        width: 450,
      },
      files: [
       { 
         cwd: 'dist/',
         expand: true,     
         src: ['**/*.html'],
         dest: 'mobile'
       },
      ]
    }
  }
});

Options

screenshotRoot

Type: String Default value: 'screenshots'

The name of the directory that will be created in the root of your application.

url

Type: String Default value: 'http://optimizely.com/'

A string value specifying the root url where you would like screenshots taken and paths referenced from.

width

Type: number Default value: 1024

A number specifying the width at which screenshots should be taken.

tolerance

Type: Number Default value: 0

Number for the allowable mismatch tolerance for overwriting.

selector

Type: string Default value: body

Selector for screenshot to be based upon, ex: '#outer-wrapper'

gm

Type: boolean Default value: false Note: If flagged as true ImageMagick or GraphicsMagick must be globally installed on the user's machine via HomeBrew or some other medium

A flag specifying if you would like to compare screenshots with GraphicsMagick. Resemble CLI was created in a way that the user does not have to globally install external dependencies such as PhantomJS, CasperJS, ImageMagick, and GraphicsMagick. Therefore, default behavior is to compare images using ResembleJS. Comparing without GM is a much slower process as Phantom has to fire up a webpage to compare images within using Resemble.

debug

Type: boolean Default value: false

This flag was developed primarily for the Resemble CLI and it has not been tested in the grunt plugin. It essentially will run the Phantom child process in debug mode.

If you would like to debug the grunt task I suggest using build-debug

grunt.initConfig({
  injector: {
    options: {},
    files: {
      'dest/default_options': ['src/testing', 'src/123'],
    },
  },
});

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
