How to write tests for axum-login?

[thor314]

Integrating axum-login into a server, it's not immediately obvious what interface axum-login provides to my front-end, or how to test a login cycle. Is there any documentation here? I found this old discussion, but i'd appreciate if anyone could point me toward a more complete source of documentation on testing with axum-login, and what shape my frontend api caller should expect.
ref: #168

what shape my frontend api caller should expect

I'm not exactly sure what you mean by this.

Taking a step back, axum-login doesn't have an opinion about your front end (or if you even have one): you implement an arbitrary authn (and optionally authz) workflow via the provided traits. The workflow and its details are entirely up to you.

So in that regard, beyond the discussion you linked, it's not clear there's much more to say about this.

Specific workflows may want to provide specific testing (of that logic) but that isn't really related to axum-login directly.

I've run into a couple weird issues, like axum-login trying to delete tokens from my database in ways that I'm uncertain how to resolve. Could I induce you to write tests for your examples? I'm uncertain I can actually resolve these on my own.
e.g., an error I've run into:
2024-03-26T01:18:25.840345Z DEBUG call:call:login{user.id="alice"}: sqlx::query: summary="delete from \"tower_sessions\".\"session\" where …" db.statement="\n\ndelete from\n \"tower_sessions\".\"session\"\nwhere\n id = $1\n" rows_affected=0 rows_returned=0 elapsed=347.467µs
b"{\"code\":400,\"error\":\"AuthenticationError: error returned from database: relation \\\"tower_sessions.session\\\" does not exist\"}",

Or rather, I'll do it tomorrow and see if I can reproduce the issue.

There are integration tests for two of the examples; if you track down the issue and it's not covered by these then it would be great to extend the coverage.

Besides the integration tests, the crate itself is fairly extensively tested with unit-style testing.

I wrote a test for sqlite, threw it in pr #208, and would appreciate if you could answer a few questions.

I think I've found the source of my issue, documented in PR #210, mentioned 4 comments above this one.
