When you "test," do you do so with a version designed to be tested, or do you take a production version and test something new with that? Do you use the tested version to then build the final product, or do you build the final product and hope it passes the tests?
I haven't been following this, but if they caused a production capsule to explode, what were the chances of that explosion happening while the capsule was docked at the ISS?

This was the same capsule that flew to the ISS a month before the test.
