Hello everyone, I am working on a new project using SqlAlchemy Core 1.4 with Postgresql and wanted to implement the following pattern for my tests:
- Before each test I would start a transaction (in a @pytest.fixture(autorun=True)) - Each test may create its own transactions - At the end of each test, I would rollback the transaction The purpose is to keep the database "clean" between tests and not have to manually delete all inserted data. However, it seems that SqlAlchemy 1.4 is deprecating nested transactions and that they will be removed in 2.0. Is there an alternative approach or best practice that I can use for isolating tests in transactions? I had an alternative idea, like: - Before each test create the first savepoint (let's call current savepoint N) - Catch any commit in the code and instead create a savepoint N+1 - Catch any rollback and rollback to N-1 Obviously, that seems like a lot of work and I'm not even sure if I can intercept begins, commits and rollbacks that easily. Alternatively, I could run upgrade and downgrade migrations on every test, but that would slow the test suite down a lot. Any advice and thoughts would be appreciated. Thanks!
