6.2.1 Initial user tests

As with the other features of our sample app, we’ll add User model
validations using test-driven development. Because we didn’t pass the

--no-test-framework

flag when we generated the User model (unlike, e.g., Listing 5.31), the
command in Listing 6.1 produces an initial spec for testing users, but
in this case it’s practically blank (Listing 6.4).
