A few tests need to be updated to match the new output this produces. I suspect it's as simple as changing from test() to runtimeTest() for the ones that are asserting about the config being in the output.

test() will run under both modes, runtimeTime() runs only when in run-time mode, and there's also buildTimeTest() for the opposite.

Thanks!
