I thought about this too (should’ve put it in the question above), but it does not fit the bill:
- it adds a lot of visual noise even in case of success
- it defies the purpose of a separation into tests and test sets (by adding hundreds of
@testsets with just a single test in it), especially since the test is really “check for L2 error” and the info on which variable fails is only to help users with tracking down errors faster
Thus I am still looking for alternatives (and/or community input whether this is something to write up as a feature request).
