Re-Blog: JavaScript Multi Module Project – Continuous Integration

Posted Jun 11, 2014

Our friend Lubos Krnac describes how to integrate Sauce with Protractor in a quest to implement continuous integration in his JavaScript multi module project with Grunt. Below is a quote from his most recent blog post along side some code.

Read the rest of his post to get the full how-to here.

An important part of this setup is Protractor integration with Sauce Labs. Sauce Labs provides a Selenium server with WebDiver API for testing. Protractor uses Sauce Labs by default when you specify their credentials. Credentials are the only special configuration in test/protractor/protractorConf.js (bottom of the snippet). The other configuration was taken from the grunt-protractor-coverage example. I am using this Grunt plug-in for running Protractor tests and measuring code coverage.

You may ask "how can I use localhost in the configuration, when a remote selenium server is used for testing?" Good question. Sauce Labs provides a very useful feature called Sauce Connect. It is a tunnel that emulates access to your machine from a Selenium server. This is super useful when you need to bypass company firewall. It will be used later in main project CI configuration.
