Add selenium & tests

[freelibre]

This is a Work in progress for issue:
#391

With this you can log in a Selenium grid console with 2 browers (chrome & firefox):
http://localhost:4444/grid/console
An exemple test case is added in side format (exported from firefox selenium IDE)
A new npm package is added to launch side test from CLI

Next steps proposal:

• try to launch side-runner tests automatically and get result in grid thru VNC
• try to add it in Travis
• try to add existing behat test

Thank you for this 👏

IMHO, the final goal is to have browser tests written in Behat/Gherkin language.
I think this is more maintainable, and we can have access to the database, to create fixtures, for example.

Selenium IDE can be cool, so that "random" users can help us write tests.
I found salmabenhadjali/gherkinator that allows to convert *.ide files to Gherkin language.
A pretty nice workflow would be:

• People create *.ide files without any knowledge of Gherkin
• We convert them to Gherkin language automatically

Actually, I would like to give a try to symfony/panther, it looks like it is way easier to use than full-stack Selenium.
Let me try to setup symfony/panther on the project. It looks like it is not supported out of the box in Behat (see Behat/Symfony2Extension#145), but it should be easy.

Thank you for your feeback. I think *.ide file will be deprecated soon so I've proposed *.side files generated by the new IDE version. It should be possible to then use selenium-side-runner to run tests. You are right such files generated are indeed more for people willing to contribute by adding some End 2 End scenario without lot of coding knowledge as it just needs the browser extension you can grab firefox extension for example and such tests could be generated and updated very quickly. I'm trying behat/mink facebook\php webdriver to interface with selenium hub but your solution seems much wiser.

While digging around I came across Zalenium.
It seems to have more features enabled out of the box.

• zalando/zalenium
• docker-selenium

[freelibre]

Yes you are right Zalenium add more features. If you want I will change to Zalenium. I've just push the VNC support to current selenium install so now you can connect to a node URL:5900 with a VNC client like TigerVNC or Remmina (the login password is : secret) and then you will be able to see the tests playing in a browser.
