# mocha-given
[](https://travis-ci.org/rendro/mocha-given)
[](http://badge.fury.io/js/mocha-given)
Mocha-given is a mocha interface that helps you write cleaner specs using `Given`, `When`, `Then` and `And`.
It is a shameless port of Justin Searls' [jasmine-given](https://github.com/searls/jasmine-given) which is a tribute to Jim Weirich's terrific [rspec-given](https://github.com/jimweirich/rspec-given) gem.
## Example Specs
``` coffeescript
describe 'assigning stuff to this', ->
Given -> @number = 24
When -> @number++
And -> @number *= 2
Then -> @number == 50
describe 'assigning stuff to variables', ->
subject = null
Given -> subject = []
When -> subject.push('foo')
Then -> subject.length == 1
describe 'Testing deferred', ->
Given -> @t = Date.now()
Then.after 1500, 'so much time has passed', -> Date.now() - @t >= 1500
describe 'Testing async', ->
Given -> @subject = new User()
Then 'save user', (done) -> @subject.save(done);
```
## Run tests
### Global installation of mocha
If you have mocha installed globally you need to install mocha-given globally as well.
```
$ npm install -g mocha mocha-given
```
Then you can run your tests by setting the interface of mocha to mocha-given
```
$ mocha -u mocha-given --compilers coffee:coffee-script -R spec
```
### Local installation of mocha
If you have installed mocha and mocha-given locally
```
$ npm install mocha-given coffee-script
```
you have to call the mocha binary directly:
```
$ ./node_modules/.bin/mocha -u mocha-given --compilers coffee:coffee-script -R spec
```
## Run mocha-given tests & start contributing
To run the `mocha-given` tests for developing, it has to be symlinked into the `node_modules` folder to enable `mocha` to resolve `mocha-given`.
Therefore run the script:
```
$ npm run link
```
Afterwards `mocha` has to be installed with ` $ npm install mocha`.
Now you can run the tests using `$ npm tests` and start contributing.
## Run tests programmatically
``` javascript
var Mocha = require('mocha');
var fs = require('fs');
var path = require('path');
// require mocha-given after Mocha is set
require('mocha-given');
// the directory with your tests/specs
var testDir = 'tests';
// First, you need to instantiate a Mocha instance.
var mocha = new Mocha({
ui: 'mocha-given',
reporter: 'spec'
});
// Get test files
fs.readdirSync(testDir).filter(function(file){
// allow javascript and coffescript files
return file.match(/\.(coffee|js)$/);
}).forEach(function(file){
mocha.addFile(
path.join(testDir, file)
);
});
// Now, you can run the tests.
mocha.run(function(failures){
process.on('exit', function () {
process.exit(failures);
});
});
```
Run from command line (with mocha and mocha-given installed):
```
$ node runtests.js
```
