Refactor OIDC tests to better mimic an actual OIDC provider #13910

sandhose · 2022-09-26T16:22:25Z

This implements a fake OIDC server, which intercepts calls to the HTTP client.
It makes the tests more accurate, by covering more internal methods.

One particular example was the ID token validation, which was mocked before.
This helped me uncover a LIE we had in our dependencies: we actually need at least authlib 0.15.1, and not just >=0.14.0 (which looks fine for packagers, according to repology)
I initially did this, because I needed to actually test the OIDC Backchannel Logout implementation in #11414

Instead of constantly mocking the internal methods of the OIDC handler, it now mocks HTTP responses Signed-off-by: Quentin Gliech <[email protected]>

Left a few notes to help with review

So that was a LIE.

Instead of having to set an HTTP phrase explicitly, we just get it from the RESPONSES dict, which maps HTTP status codes to status phrases

Do we not use this? I'm quite confused by the changes in this file -- they seem unrelated to the rest of the PR.

Oh, I see this got moved below.

Still this refactoring seems like it could be split out for a separate review.

Looks like deb building in CI is broken because of an old version of authlib... even though the logs says it installs 1.1.0! And I can't reproduce the issue locally, poetry run python ./scripts-dev/build_debian_packages.py just works 🤔

EDIT: nevermind, I was on the wrong branch, I can reproduce locally

I think this largely looks good, most of my comments are fairly cursory.

A couple minor renames, but looks good! 👍

Synapse 1.71.0 (2022-11-08) =========================== Please note that, as announced in the release notes for Synapse 1.69.0, legacy Prometheus metric names are now disabled by default. They will be removed altogether in Synapse 1.73.0. If not already done, server administrators should update their dashboards and alerting rules to avoid using the deprecated metric names.
