Guidelines for tests as a Spec?

I think that we should push for Tests in all implementations. However a question arises, how and what do we exactly test? I don’t know if there are tools for writing framework/language agnostic tests but something like:

  assert.equal(ProfileName, 'Alon Bukai', 'Author name is correct');

Just my 2 cents but I think the way it’s worded here is perfect for realworld (other than using the term TDD when it’s probably just referring to testing like mentioned above). If every repo sort of serves as a representative of that community I think that most people will be implementing some unit testing and if it’s not there initially it would be a great contribution opportunity for the next developer. I don’t think it needs to be required though.

@EricSimons TDD is test driven development. Writing tests before writing any other code and then iterating towards passing tests.
