| """Shared pytest fixtures. | |
| The validation engine defaults to a process-global Redis/in-memory cache so | |
| results are reused across runs. That is correct in production but leaks state | |
| between tests — one test's cached DNS/MX then satisfies the next test's | |
| "resolution happened" assertion. | |
| Clearing the in-memory tier between tests keeps the suite hermetic without | |
| every test having to inject its own cache. Tests that assert on caching still | |
| inject a recording cache explicitly. | |
