Added initial test structure and first test - WP

[fonsecas72]

Hi, I want to known what do you think of adding some tests at least to help out with development .

This is just in the very beginning but tell me what do you think.

How to make it work: After running vendor/bin/behat A directory build will be created with the generated template.

btw: I've just copied and pasted the behat context so bear with me
