|
|
## Installation
|
||
|
|
|
||
|
|
The easiest way is to install `karma-coverage` as a `devDependency`,
|
||
|
|
by running
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npm install karma karma-coverage --save-dev
|
||
|
|
```
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
For configuration details see [docs/configuration](docs/configuration.md).
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
### Basic
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
// 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/'
|
||
|
|
}
|
||
|
|
});
|
||
|
|
};
|
||
|
|
```
|
||
|
|
### CoffeeScript
|
||
|
|
|
||
|
|
For an example on how to use with [CoffeeScript](http://coffeescript.org/)
|
||
|
|
see [examples/coffee](examples/coffee). For an example of how to use with
|
||
|
|
CoffeeScript and the RequireJS module loader, see
|
||
|
|
[examples/coffee-requirejs](examples/coffee-requirejs) (and also see
|
||
|
|
the `useJSExtensionForCoffeeScript` option in
|
||
|
|
[docs/configuration.md](docs/configuration.md)).
|
||
|
|
|
||
|
|
### Advanced, multiple reporters
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
// karma.conf.js
|
||
|
|
module.exports = function(config) {
|
||
|
|
config.set({
|
||
|
|
files: [
|
||
|
|
'src/**/*.js',
|
||
|
|
'test/**/*.js'
|
||
|
|
],
|
||
|
|
reporters: ['progress', 'coverage'],
|
||
|
|
preprocessors: {
|
||
|
|
'src/**/*.js': ['coverage']
|
||
|
|
},
|
||
|
|
coverageReporter: {
|
||
|
|
// specify a common output directory
|
||
|
|
dir: 'build/reports/coverage',
|
||
|
|
reporters: [
|
||
|
|
// reporters not supporting the `file` property
|
||
|
|
{ type: 'html', subdir: 'report-html' },
|
||
|
|
{ type: 'lcov', subdir: 'report-lcov' },
|
||
|
|
// reporters supporting the `file` property, use `subdir` to directly
|
||
|
|
// output them in the `dir` directory
|
||
|
|
{ type: 'cobertura', subdir: '.', file: 'cobertura.txt' },
|
||
|
|
{ type: 'lcovonly', subdir: '.', file: 'report-lcovonly.txt' },
|
||
|
|
{ type: 'teamcity', subdir: '.', file: 'teamcity.txt' },
|
||
|
|
{ type: 'text', subdir: '.', file: 'text.txt' },
|
||
|
|
{ type: 'text-summary', subdir: '.', file: 'text-summary.txt' },
|
||
|
|
]
|
||
|
|
}
|
||
|
|
});
|
||
|
|
};
|
||
|
|
```
|
||
|
|
|
||
|
|
### FAQ
|
||
|
|
|
||
|
|
#### Don't minify instrumenter output
|
||
|
|
|
||
|
|
When using the istanbul instrumenter (default), you can disable code compaction by adding the following to your configuration.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
// karma.conf.js
|
||
|
|
module.exports = function(config) {
|
||
|
|
config.set({
|
||
|
|
coverageReporter: {
|
||
|
|
instrumenterOptions: {
|
||
|
|
istanbul: { noCompact: true }
|
||
|
|
}
|
||
|
|
}
|
||
|
|
});
|
||
|
|
};
|
||
|
|
```
