JS Test, the JavaScript unit testing framework that Google uses in-house has been released as an open source project.

JavaScript is, arguably, the most important language of the moment and yet it lacks the tools needed to get the job done quickly and efficiently. In particular it lacks a well supported unit testing framework - or it did until now

JS Test, the unit testing framework that runs on V8, Google's open source JavaScript engine has been released as an open source project.

According to the announcement was made on the Open Source at Google blog notes that JS Test has the following features:

  • Fast startup and execution time, without needing to run a browser.
  • Clean, readable output in the case of both passing and failing tests.
  • An optional browser-based test runner that can simply be refreshed whenever JS is changed.
  • Style and semantics that resemble Google Test for C++.
  • A built-in mocking framework that requires minimal boilerplate code (e.g. no $tearDown or $verifyAll calls), with style and semantics based on the Google C++ Mocking Framework.
  • A system of matchers allowing for expressive tests and easy-to-read failure output, with many built-in matchers and the ability for the user to add their own.
