Thanks!! That's indeed the same problem and removing the '$' from the exclude_regex worked for me. (ostestr --blacklist_file tests-py3.txt --regex "nova.tests.unit.network" ran all non-blacklisted network tests)

I could see that because conceptually the test selection has two stages: produce a list of non-blacklisted tests, then filter that list further as desired. Personally, using --blacklist_file and --regex seemed straightforward to me since I could specify the filter regex as I'm used to doing. It worked in my case but there might be cases I can't think of where the append method won't be able to give the desired result.
