refactor(test): use the expected name for initializing tests.

Originally I used setup_test because something went wrong when I used setUp.  I
wrote https://github.com/pytest-dev/pytest/issues/8424 about it.  There they say
to use `-p no:nose` to disable nose interpretation.

But now I simply went back to setUp, and all seems well? Not sure what changed,
but using the expected name is better.
