Completed Recipe controller/model CRUD testing

[Mirv]

Note: There are going to be hella issues with this one - sorry - I can't even begin to predict how the views will handle the checkboxes & select you had setup.

This update should mainly affect the Recipe Controller/Model & tiny bit of view

• model testing

  • presence/validation of 8 variables from Recipe table
  • yaml file even though not used much reflects this & we can use it later

• controller testing

  • CRUD functions except create are covered
  • CRUD doesn't include reviews & likes or comments (the last one should be tested by disqus already)

• not tested

  • helpers
  • technically, routing - Section 9 in http://guides.rubyonrails.org/v4.2/testing
  • chef ... this can probably be saved by using find+replace to sub in user in place of chef?

---

Extra:

Documentation of the process & some decisions on issue #30 ... like removal of spring gem & inclusion of guard to test automatically after a test file is saved
