Introducing Yeti: The YUI Easy Testing Interface
At YUI, we use Selenium and Hudson for running YUI Test-based unit tests on various browser and operating system configurations as part of our continuous integration strategy. This is great for catching problems that result from integrating your work with the rest of a complex software stack. It comes with a price: CI tools like these are complicated to setup and maintain. In any case, they don't help you while you're developing code and testing before you commit.
Today, I'm excited to release Yeti 0.1.0, an experimental command-line tool designed to make cross-browser testing easier before you commit a line of code.
yeti test.html to get the results of the YUI Test-based test in
test.html. You can pass multiple HTML documents to test multiple components at once.
The real power of Yeti is running tests in multiple browsers simultaneously. Although Yeti can open your tests one-by-one on your computer, Yeti allows you to run tests on any browser on any device—all at the same time.
If you run Yeti without arguments, it will start a web server that you can access at
http://localhost:8000. You can then point browsers or devices on your network to that URL and every test you run from that point will be executed on all browsers visiting the test page.
When combined with the excellent localtunnel, firewalls between you and other computers are less painful. If you're not working with sensitive information, it's a simple way to make your Yeti available to the internet:
$ localtunnel 8000 Port 8000 is now publicly accessible from http://example.localtunnel.com
You can then visit that URL to access Yeti and start running tests:
This is especially useful for cellular devices: You can use your carrier's internet connection without needing to get your device on the same network as your development computer.
Getting the code
$ npm install yeti@stable
If you haven't installed NodeJS and npm and you're on a recent Mac, you can still install Yeti with a convenient installer.
|Download the Yeti 0.1.0 Installer 2.7 MB |
Requires Mac OS X 10.6 and a Intel Core 2 processor or better
If your computer doesn't meet the installer's requirements, you can still use Yeti if you're able to install npm. More installation and usage instructions are available in Yeti's README.
Your participation is welcome
Yeti is the first project we've launched in YUI Labs, an umbrella category where our new ideas and initiatives will take shape. As such, Yeti is offered without the same level of support as our other projects. We still encourage you to ask questions and give feedback in Yeti's forums and hope Yeti makes testing easy and fun. If it doesn't, please tell us, file a bug or consider contributing to Yeti.
