Write tests

I'll be writing the tests for the 3.0.x-dev branch.

I created a MR for this for basic tests.

The tests:

- Creates a "random_food" vocabulary with some terms
- Goes to /admin/structure/block to add the new jQCloud block in the content section
- Goes to the Home Page to check the existence of the block, its title and the contents

I wish I could do more tests, but that is all I can do for now, given the money constrains, if anyone has some time to contine on this, be my guest, I'll leave it to "Needs Review" for a while, then I'll mark it as "Fixed".

Feel free anyone to re-open if wants to continue on this.

A screenshot:

Fixed a few CSPELL/PHPCS that came out after this.

I'll move this to "Fixed" for not, if anyone needs more tests, feel free to move this to "Needs work" and I'll implement these. I might open a new issue for more tests to implement.

Automatically closed - issue fixed for 2 weeks with no activity.
