grunt-screenshot

forked from https://github.com/Ferrari/grunt-autoshot

a grunt plugin to take remote and local screenshots

Getting Started

This plugin requires Grunt.

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-screenshot --save-dev

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

grunt.loadNpmTasks('grunt-screenshot');

Final and the most important thing, please make sure phantomjs is in your PATH, if your windows users, please download the phantomjs zip file and decompress it and don't forget to set the environment variable as phantomjs.exe's path. Cause this plugin use phantomjs to generate screenshot, so remember install it first.
