Description
For the following test function, code and test details unimportant:
def test_apifail_inventory_no_object_invs(subtests):
"""Confirm no-objects inventories don't import."""
inv = soi.Inventory()
with subtests.test(msg="plain"):
with pytest.raises(TypeError):
soi.Inventory(inv.data_file())
with subtests.test(msg="zlib"):
with pytest.raises((TypeError, ValueError)):
soi.Inventory(soi.compress(inv.data_file()))
d = {"project": "test", "version": "0.0", "count": 0}
with subtests.test(msg="json"):

This is problematic when a subtest fails and something like --tb=line is used. After making a breaking edit to one of the subtests and rerunning:
>pytest -vk no_object --tb=line

It would be nice to have the msg reported with each subtest, so as to avoid having to rerun the test with expanded context to identify offending case(s).
