  • Venus.js (Development)

    Venus is a testing tool for JavaScript (JS), which simplifies running unit tests. When you are developing a browser-based project in JS, you'll want to create unit tests and run them frequently. Typically, you'll write a unit test using some library, such as Mocha or Jasmine. These libraries let you define test cases (or "specs" if you are following a BDD style), and provide APIs for writing assertions.

  • HTML5 Dev Conf Talk on Nightwatch.js (Other amazing things)

    There are many libraries and tools available for writing Selenium tests. Unfortunately, until recently there have not been good options available if you want to implement your tests using JavaScript. Nightwatch.js aims to solve that problem, by providing a robust solution for writing and running Selenium test automation. This tool runs on Node.js and is growing quickly in popularity, with over 1,500 stars on GitHub and an active development community. In this talk, we will explore the capabilities of Nightwatch, and specifically answer key questions around debugging, abstraction using the page object model, reporting options, and more. An in-depth demo will also be shown to give attendees an introduction to setting up and using the tool.

  • LinkedIn Tech Talk on Venus.js (Other amazing things)

    This talk begins with a brief overview of different ways to test code written for the web, including black-box vs. white-box testing techniques. From here, we focus on white-box unit testing and how to write unit tests for JavaScript code using Venus.js. By the end of the session, you will understand why unit testing is important, the challenges involved in unit testing JavaScript code, and the tools and techniques which are available to overcome these challenges.
