Mocha Sauce is a bleeding edge project that connects Mocha with Sauce Labs, created by Paul Bakaus as part of his work at Zynga. It was initially developed as a fork of mocha-cloud but has since become a standalone project with additional features and improvements. The goal of Mocha Sauce is to enable unit tests to run in the browser, as a pre-commit hook, in multiple remote VMs / browsers, and integrated with Jenkins for continuous integration. To achieve this, it builds on existing libraries such as mocha-phantomjs and Sauce Labs, which provide features like running tests in a headless browser and automatically instantiating a pristine remote virtual machine. Mocha Sauce aims to address the missing link between these technologies by providing advanced features like using Sauce Connect to create a local tunnel for testing firewalled or local URLs in VMs. The project is still alpha code, but it has been successfully used in production at Zynga and is being actively developed with community feedback.
