 Fixtures: shared data as **class-level constants** (`URL`, `AUTH`, `AUTHZ_REQUEST`); single-use data inline in the test method.
 
 Assertions and mocking:
 
 - Prefer `assertRaises`, `assertIsNone`, `assertIsInstance` over bare `try/except`.
 - Assert **current** client behavior — not obsolete error text or exceptions.
