Instruments files with Blanket.js
npm install grunt-blanket> Instruments files with Blanket.js in the "traditional" manner of creating physical instrumented copies of the files. Ideal for situations where you'd like to use mocha or browser based test coverage, but don't want to have to use a non-JS solution to instrument your files.
~0.4.0If 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:
``shell`
npm install grunt-blanket --save-dev
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
`js`
grunt.loadNpmTasks('grunt-blanket');
to the data object passed into grunt.initConfig().`js
grunt.initConfig({
blanket: {
options: {
// Task-specific options go here.
},
your_target: {
// Target-specific file lists and/or options go here.
},
},
})

Only the data-cover-flags from Blanket are accepted as options. They may add some needed functionality, but you likely won't need them.

#### Default Options
In this example, our source files are contained in 'src' and we want them to be instrumented and then stored in 'src-cov'.
NOTE: The src parameter MUST be a directory. Patterns like "src/*.js" will fail. Individual files can be included or excluded via the pattern option.
`js
grunt.initConfig({
blanket: {
options: {
// pattern: "*/interesting*.js"
pattern: "!src/some/dir/to/exclude/*/"
},
files: {
'src-cov/': ['src/'],
},
},
})
``Also, the coverage details are only viewable with the mocha reporter, for now. A copy of the blanket reporter may be made available at a later date.
