> With paramterized tests *all* the tests are run and *all* failures reported. With testing in a loop the tests stop at the first failure.

+1 to this justification.  Parameterized tests are a big win over a simple for loop in a test.

(However, I haven't looked at the IPython code at all, and Antoine's objection seemed to have something in particular to do with the IPython code?)
