Automated browser testing with Node.js + Selenium

By Philippe Leefsma

SeleniumHQ is a free set of tools and APIs that allow you to simulate user actions in a browser, locate html elements such as buttons, inputs, send clicks and so on... This is what our development team is using, among other tools, to automate tests with the viewer.

I gave a quick shot at it and it looks promising: Selenium API can be invoked with no less than seven programming languages! Java, C#, Python, Ruby, PHP, Perl, JavaScript (node.js).

I'm a big Node.js addict, so I tested again Node. The steps involved to set it up on your machine are very easy:

1/ Download the Selenium server from their download section

2/ The version at the time of this writing (2.48.2) requires Java SDK7 to be installed, so you may need to update your Java setup

3/ Run the Selenium server: Java -jar path-to-selenium-srv.jar

4/ Write your test and run it based on the framework you selected. If you are using Node, an npm package is available: selenium-webdriver

I created a basic test which already does a bit of work:

- It will start a web browser using the url of my gallery at http://gallery.autodesk.io.  My test supports firefox and chrome (an additional chromedriver package is required for chrome and the setup is slightly different).

- It will then wait for the model buttons to appear and will open a specific one: Engine

- Once the model is loaded, it will open the extension manager dialog and successively toggle each extension On and OFF. Some extensions are displaying an alert dialog, so a specific handling in that case is needed

That's it. Obviously each extension would require to write a specific test in order to be tested properly and some maybe tricky, but this is already a decent start. I'm also attempting to access the browser console output but I couldn't get it to work properly so far... Work in progress.

Here is the full node.js script of my selenium test:

Sorry I'm not a Selenium expert, if you have specific questions about using Selenium IDE, you may seek support directly with them.

To complete Setup and Installation of Nightwatch js Testing framework and we will create Test plan and test case, we will manually test a real website and then take those test case and we will automate it. Simpliv is providing good course check by following link and start learning today.
