I haven’t had time to look at this in detail yet, but when I originally had this idea I thought we would use lit’s discovery mechanism to find all .py files, and then invoke them using dotest.py in single process mode with a path to a specific file.<br><br>Why do we need run lines?<br><div class="gmail_quote"><div dir="ltr">On Wed, Apr 4, 2018 at 5:04 AM Pavel Labath via Phabricator <<a href="mailto:reviews@reviews.llvm.org">reviews@reviews.llvm.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">labath added a comment.<br>

I'm not aware of any code which would do the full visit. We have some code in dosep.py (`find_test_files_in_dir_tree`), but this one only does file traversal. It does not look inside the the files for classes, test methods and such.<br>
<br>
The real visiting happens inside unittest2 (loader.py). The code there seems very complicated, but I think that's because it tries to support various things we don't use, so /I hope/ that our visiting logic can be simpler.<br>
<br>
OTOH, looking at loader.py, it seems to me it may actually be possible to let it do the enumeration for us, if we stroke it the right way.<br>
