Chimp.js

     

 

An awesome developer-centric experience to writing tests with realtime feedback using Mocha, Jasmine or Cucumber.js.

!Chimp by Xolv.io

Chimp can be used with any technology stack as it allows your to write your test automation in the language of the web: JavaScript.

Traditionally only available for unit testing, and now you can get super fast feedback for your acceptance and end-to-end tests:

!Realtime feedback

Set an @focus tag in the spec title, save a file, Chimp reruns the spec until you make it pass.

Checkout our new book where you can learn how to can use Chimp across the Full Stack from React to Node.JS, Mocha, Meteor and more.

Quality Faster by Sam Hatoum, creator of Chimp.

$3

``sh
npm install -g chimp
`

Be sure to checkout our Automated Testing Best Practices repository.

Having trouble? See the installation documentation.

$3

For development mode, you can use the watch mode:
`sh
chimp --watch
`
You can also easily change the browser Chimp with --browser, e.g. --browser=phantomjs

$3

`sh
npm install chimp
`

$3

`sh
let Chimp = require('chimp');
let options = require('./my/config/for/chimp');
options['_'] = [
'/my/path/to/node',
'/my/path/to/my/project/node_modules/.bin/chimp.js'
];
let chimp = new Chimp(options);
chimp.run(function (err, res) {
console.log('CHIMP RES:',res);
console.log('CHIMP ERR:',err);
//next action after chimp finish
});
`

Additional Features

###### Synchronous Javascript
![WebdriverIO](http://webdriver.io/)

We chose WebdriverIO for it's awesome API and made it awesomer by converting it to a synchronous syntax:

`javascript
browser.url('http://google.com'); // SETUP

var title = browser.getTitle(); // EXECUTE

expect(title).to.equal('Google'); // VERIFY
`

No callback-hell or confusing assertions with promises, just easy-to-read synchronous code that works as you expect it to.

###### Easy CI
!CI

Chimp is tested on all the popular CI servers. We genuinely just want you to focus on writing tests and let us deal with all the boring bits!

###### Mocha, Jasmine or Cucumber.js
!Test Frameworks

Some developers love Jasmine and Mocha, and some teams love to use Cucumber for BDD. We decided to give you the choice between the best in class test frameworks for writing end-to-end and acceptance tests.

###### Client & Server

End-to-end and acceptance testing often require you to setup data on the server and reset state between specs.

Using our synchronous version of the request module, you can call your server to reset your system or setup data like this:

`javascript
var userId = request({
url: 'http://localhost:3000/fixtures/createUser'
method: 'POST',
json: true,
body: {username: 'Bob', password: 't0ps3cret'}
});
`

Or if you are using Meteor, you can get fancy with our server.execute method:

`javascript
var privateSetting = server.execute(function(settingKey) {
return Meteor.settings[settingKey];
}, 'privateSetting')
`

###### Lots more
Chimp is PACKED with features that make your life easier. See the documentation site for more details.

Using Meteor?

Chimp comes with first-grade Meteor support out-of-the-box, including hot-deploy detection that runs specs after your Meteor client or server restart.

Be sure to checkout our Automated Testing Best Practices repository which is written using Meteor.

$3

In development mode, use the watch mode:
`sh


start your Meteor app first


chimp --watch --ddp=http://localhost:3000
`

On CI, can select the browser:
`sh


start your Meteor app first


chimp --browser=firefox --ddp=http://localhost:3000
`

#### Multiple Meteor Servers
If you'd like to run a test with more than one Meteor app server, you can do so by running the same app on multiple ports and providing mulitple -ddp options to chimp:
`


start first app

meteor --port 3005

start second app in another shell

meteor --port 3007

run chimp in another shell

chimp --watch --ddp=http://localhost:3005 --ddp=http://localhost:3007
`
Then you can access the servers in your tests on the global server.instances property
`
it('has PORT env var set', function() {
function getRootUrl() {
return process.env.ROOT_URL;
}
expect(server.instances[0].execute(getRootUrl)).to.equal('http://localhost:3005/');
expect(server.instances[1].execute(getRootUrl)).to.equal('http://localhost:3007/');
});
