mateo-berri 758f72e41f tests(e2e-cassette-proxy): add mitm.it to passthrough hosts
mitmproxy serves its current-instance CA certificate at the magic
host ``mitm.it/cert/pem``. The CI pipeline downloads that CA in the
``Fetch CA from cassette-proxy`` step and trusts it (certifi append +
system trust store) so subsequent in-process tests can validate
mitmproxy's MITM leaf certs.

Once the previous commit fixed the replay path so cache hits actually
serve, the very first ``mitm.it/cert/pem`` lookup hit a stale entry
from a prior CI run — the proxy handed back a CA generated by a *previous*
mitmdump instance with a different private key. The CI then trusted that
stale CA, mitmproxy in the *current* run signed leaf certs with its fresh
CA, and every TLS handshake failed:

  SSL: CERTIFICATE_VERIFY_FAILED:
    certificate verify failed: authority and subject key identifier mismatch

This took down langfuse_logging_unit_tests (at ``test_embedding.py``
collection), search_testing, and image_gen_testing.

Adding ``mitm.it`` to the passthrough host list short-circuits in
``_should_skip`` before any Redis lookup, so the CA is always served
fresh from the running mitmdump instance. The poisoned key in the
shared dev Redis was deleted manually before pushing this commit.

Adds a regression test that exercises both hooks: ``request()`` must
return without setting ``flow.response``, and ``response()`` must not
persist anything to Redis.

Testing for litellm/

This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.

The point of this is to:

  1. Increase test coverage of litellm/
  2. Make it easy for contributors to add tests for the litellm/ package and easily run tests without needing LLM API keys.

File name conventions

  • litellm/proxy/test_caching_routes.py maps to litellm/proxy/caching_routes.py
  • test_<filename>.py maps to litellm/<filename>.py
