[QA] Pair programming with Zeljko - Friday - 4rth July 2014

[Vikas Yaligar]

Hello,

Last Friday we had Antoine joining us for the pair programming, as we
needed some help in creating jenkins job for the language screenshots.

* As initially Zeljko and me had used the existing template, but with that
we were only able to run only 1 language in single job. Hence Antoine
suggested us to make a new template.

* We used Matrix project plugin[1], where we can run multiple jobs with few
environment variables(it can be anything in general, if I am not wrong)
getting changed every job.

* We had to add project-type as matrix in job template and axis where we
specified all language code, for which we need to run these tests. [2]

* Then we modified the macro[3] by adding CUCUMBER_EXTRA_PARAMETERS which
stores "--tags @language-screenshot" if LANGUAGE_SCREENSHOT_CODE is set.

* We have run it in Wikimedia integration[4] and one of the awesome things
I have noticed is it runs all(currently 3) of them parallel. I am
interesting to see what happens when I run it for more languages.

Thank you Zeljko for pairing with me :)
