I’m wondering if there is some macro (or way to construct a macro?) that could identify which test is being run. Currently I use
line!() to create unique temporary directories for each test case, but that is a nuisance, because I have to look up the file to determine which directory corresponds to which test.
Is there some way to identify (in a macro) either the name of the currently running test, or the name of the function which calls a macro?
