No, I meant you write the test case with ruby and once everything works
you decide how to replicate the same with something more widely
available.

Sometimes I decide to delete the test cases I used for prototyping
because they are too convoluted, test something very esoteric, or it's
not easy to do the same in CI infraestructure.

But they helped me write the code.
