This PR adds test for SQLAlchemy's repr and fixes its handling of the no default engine scenario.
This fix assumes we want engine() to continue to throw a KeyError in that scenario (i.e. all handling is in repr itself).
SQLAlchemy.__repr__
raisesKeyError
when the default engine is not set. #1295Checklist:
