Coding Dojo: Password Validation

I'd like to think that what I amb going to do will resemble outside-in design.

First iteration

On this iteration, we only consider a basic password validation. A method receives the password string format, and returns if the password is valid or not.

I have to say that, being this iteration so simple, I have struggled to get an acceptance test that made sense. In fact, the acceptance test I've written for this iteration provides zero value.

Also, the feature was not that test-drivable (from my POV)
