We wrap calls to self.client.{patch,put,get,post,delete} for various

into the Django code. Some of this has to do with providing a future

This test class is intended to be used (sparingly!) for tests that
need to verify transaction related behavior, like locking with

Unlike ZulipTestCase, ZulipTransactionTestCase has the following traits:
1. Does not offer isolation between tests by wrapping them inside an atomic transaction.
2. Changes are committed to the current worker's test database, so side effects carry on.
All ZulipTransactionTestCase tests must be carefully written to
avoid side effects on the database; while Django runs
TransactionTestCase after all normal TestCase tests on a given
test worker to avoid pollution, they can break other
ZulipTransactionTestCase tests if they leak state.
