karma-coverage

> Generate code coverage using [Istanbul].

This is a fork of the excellent karma-coverage plugin.
This simply removes the CoffeeScript coverage option, which is temporarily needed as the dependencies
in the Coffee coverage modules are causing problems for some projects.

Installation

The easiest way is to keep karma-coverage as a devDependency in your package.json.
``json
{
"devDependencies": {
"karma": "~0.10",
"karma-js-coverage": "~0.2.0"
}
}
`

You can simple do it by:
`bash
npm install karma-js-coverage --save-dev
`

Configuration


Following code shows the default configuration...
`js
// karma.conf.js
module.exports = function(config) {
config.set({
files: [
'src/*/.js',
'test/*/.js'
],

// coverage reporter generates the coverage
reporters: ['progress', 'coverage'],

preprocessors: {
// source files, that you wanna generate coverage for
// do not include tests or libraries
// (these files will be instrumented by Istanbul)
'src/*.js': ['coverage']
},

// optionally, configure the reporter
coverageReporter: {
type : 'html',
dir : 'coverage/'
}
});
};
`

$3

#### type
Type: String

Possible Values:
* html (default)
* lcov (lcov and html)
* lcovonly
* text
* text-summary
* cobertura (xml format supported by Jenkins)
* teamcity (code coverage System Messages for TeamCity)

If you set type to text or text-summary, you may set the file option, like this.
`javascript
coverageReporter: {
type : 'text',
dir : 'coverage/',
file : 'coverage.txt'
}
`
If no filename is given, it will write the output to the console.

#### dir
Type: String

Description: This will be used to output coverage reports. When
you set a relative path, the directory is resolved against the basePath.

#### multiple reporters
You can use multiple reporters, by providing array of options.

`javascript
coverageReporter: {
reporters:[
{type: 'html', dir:'coverage/'},
{type: 'teamcity'},
{type: 'text-summary'}
],
}
``
