tests(pam/testutils): Integration tests for the PAM CLI by denisonbarbosa · Pull Request #109 · canonical/authd

denisonbarbosa · 2023-11-21T15:29:53Z

This adds integration tests for the PAM module and moves some code around to avoid copying and maintain consistency between our integration tests.
The golden files are ASCII representations of terminal screenshots, so don't get scared by the number of lines changed (I promise it will be okay).

I could extract the testutils changes to another pull request if they seem too much for this one. I didn't do it yet because I thought it would feel like an "empty" change in main.

Great work! Nice to see the vhs thing working in the end. I left my comments inline

I didn't go through the vhs docs yet, but maybe it would be convenient adding a README.md to the testdata folder how to generate or update the recorded files?

I don't really like adding assets that are not related to the tests themselves inside testdata/. If you feel like it's necessary to point to the vhs documentation, I could add a line comment inside the TestIntegration function (before spawning the vhs subprocess) explaining that we rely on the tool and pointing to their documentation, WDYT?

Well I'm not sure where is the right place, in other projects I contribute or mantain we normally keep a readme in the places the artifacts are so that it's easy for everyone to find out how those are generated.

However, I'm fine with other options too, I just think it's important to have the process documented so that when others will have to regenerate them can figure it out easily.

Note: I didn’t look at any comments than this exchange.

I think this is the perfect place for the contributing guide on "how to refresh blablabla" (same for golden files btw)

Great job on this! Can we ensure debian packaging works properly with these changes as well?

@denisonbarbosa I was quickly grepping on the diff and I didn't notice anything related to this, is the process documented now?

I think I was able to review every changes since the rebase. I have only 2 minor comments and then, we’ll be good from my side of things!

All good from my side! Of course, needs to solve the conflict while rebasing, but otherwise, good! :)

GabrielNagy

Looks good to me, great work here!

I think Gabriel is right, we need to skip them during autopkgtests too.

Great work! Once fixing the conflicts and rebase, you can merge :)

CONTRIBUTING.md

We wrote some helper functions for the NSS integration tests, but they will be helpful for the PAM integration tests as well. So, in order to avoid copying code and then having to maintain both helpers, it's better to move the helpers to testutils.

We need to install vhs and ttyd to run the integration tests in the CI and also export an environment variable to build the PAM module without any warnings

The CLI tests rely on external dependencies to run and they are not available in the archive, so we must skip them on environments that do not support external sources.

Since we rely on the mock to test some behaviors in the CLI tests, we have to be able to build the binary with the mock. This now is doable by using the "integrationtests" build tag.
