Poncho
Client-side JS code coverage using PhantomJS, Mocha and Blanket.
Install
$ npm i --save-dev poncho
Usage: poncho [options] <file>
Options:
-h, --help output usage information
-V, --version output the version number
-R, --reporter [type] reporter: plain (default) | lcov | json
Usage
Let's imagine that you already have Mocha client-side tests, something like this:
<!DOCTYPE html>
<head>
<meta charset="utf-8"/>
<title>Mocha Test</title>
<link rel="stylesheet" href="mocha/mocha.css"/>
</head>
<body>
<div id="mocha"></div>
<!-- mocha -->
<script src="mocha/mocha.js"></script>
<script>mocha.setup('bdd');</script>
<!-- target script -->
<script src="script.js"></script>
<!-- test file -->
<script src="test.js"></script>
<!-- run -->
<script>mocha.run();</script>
</body>
All you need to do is add data-cover attribute to the target script tag:
<script src="script.js" data-cover></script>
…and run Poncho:
$ poncho test.html
Send data to coveralls.io
Install node-coveralls:
$ npm i --save-dev coveralls
…and pipe Poncho's lcov reporter to it:
$ poncho --reporter lcov test.html | coveralls
How it works?
You don't want to know. Seriosly. It's so hacky way that it can cause the blood from your eyes.
