Save LCOV reports generated by Blanket for Grunt QUnit.
This is used to save Blanket.js tests coverage results done with grunt-contrib-qunit in order to send them to Coveralls.io with grunt-coveralls.
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-qunit-blanket-lcov --save-dev
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-qunit-blanket-lcov');
Simply follow Blanket.js guide to setup the test coverage with QUnit. No special configuration of the test suite is needed.
Your test HTML should look like :
<!DOCTYPE html>
<html>
<head>
<title>My test suite</title>
<meta charset="utf-8">
<link rel="stylesheet" href="../bower_components/qunit/qunit/qunit.css">
<script src="../bower_components/jquery/dist/jquery.min.js"></script>
<script src="../bower_components/qunit/qunit/qunit.js"></script>
<script src="../bower_components/blanket/dist/qunit/blanket.min.js"></script>
<script src="../src/library.js" data-cover></script>
<script src="core.js"></script>
</head>
<body>
<!-- -->
</body>
</html>
Don't forget to change the urls of the qunit task to add ?coverage=true for each test suite.
In your project's Gruntfile, add a section named qunit_blanket_lcov to the data object passed into grunt.initConfig().
grunt.initConfig({
qunit_blanket_lcov: {
lib: {
src: 'src/library.js',
options: {
prefix: 'http://localhost:<%= connect.test.options.port %>/',
dest: '.coverage-results/library.lcov'
}
}
}
});
Then add or edit your test Grunt task to execute qunit_blanket_lcov before qunit.
grunt.registerTask('test', [
'qunit_blanket_lcov',
'qunit'
]);
Type: string Required
Output file for LCOV data.

The prefix to remove from file paths, this is generally the host + port of the grunt-contrib-connect task you use.
Type: boolean
Default value: false
By default the task will fail if there is no coverage results to write.
Type: boolean
Default value: true
Automatically insert the custom Blanket reporter in the PhantomJS instance. If you redefined the inject option of grunt-contrib-qunit you must set this option to false and manually add node_modules/grunt-qunit-blanket-lcov/reporter.js to the inject list.
In this example the test coverage results of library.js will be saved to library.lcov.
grunt.initConfig({
qunit_blanket_lcov: {
lib: {
src: 'src/library.js',
options: {
prefix: 'http://localhost:9001/',
dest: '.coverage-results/library.lcov'
}
}
}
});
If you have many source files used by QUnit analyzed by Blanket it might be a good idea to use the Grunt files globbing option.
grunt.initConfig({
qunit_blanket_lcov: {
all: {
files: [{
expand: true,
src: ['src/*.js', 'src/plugins/**/plugin.js']
}],
options: {
prefix: 'http://localhost:9001/',
dest: '.coverage-results/all.lcov'
}
}
}
});
