CatJS 0.4.45

CatJS is an automation framework for (mobile) web applications testing. It offers a new technology that makes testing easy, we don't do WebDriver like the other technologies, in our case the applications test themselves. With simple annotations added to your HTML5 code, an automated functional tests will be available as part of your application lifecycle.

Code once, deploy it anywhere

Once you added the test code you can run it using CatJS runner (That is already part of CatJS, no need to do any additional installations), on any platform that your application supports. CatJS runner can deploy your application on multiple devices and desktop browsers.

A few facts

  • The annotations will be coded in comments thus no additional code is required
  • Once you wish to test your application, with a simple command, a new deployment will be generated for you to use including the test code
  • You get to document your tests and test your code
  • When you are ready for production the additional annotations will be removed on the minify process.
  • CatJS is an NPM and can be used as a command-line and/or as a module (The module will be available in the next releases) @catjsteam You can visit our catjs forum. Comments and questions are more than welcome, our team can help and consult about how to test your web application.
