[WIP] Add unittest session handling, --snapshot-update support #144

Open medmunds opened 3 years ago

medmunds commented 3 years ago

Add test-session-level features for raw unittest framework:

Support --snapshot-update command line option
Issue "SnapshotTest summary" at end of test run
Remove unused snapshots when in update mode

This also adds snapshottest-augmented versions of the various ways to run unittest:

python -m snapshottest ... parallels python -m unittest ... (via module-level __main__.py).
snapshottest.main() wraps unittest.main().
SnapshotTestRunnerMixin can be used with other unittest TestRunner classes.

Closes #51

Still need to:

[ ] Finalize namespaces and naming (is it weird that the module-level __main__.py would be used for unittest-specific features?)
[ ] Add tests
[ ] Track down some odd behavior where --snapshot-update only writes files if the snapshot data has changed, affecting all of nose/django/unittest, but not pytest (and apparently pre-dating this PR)
