Working on integration/conformance tests, if anyone is interested to join!

Hi all,

I am experimenting with running the testsuite of ~https://github.com/apple/ccs-caldavtester~ https://github.com/CalConnect/caldavtester

The setup is challenging because it expects Python2, however I got it to work with nix. My (very-WIP) state is visible under https://github.com/oliverpool/go-webdav/tree/nix/testintegration :

• an http server is started in a goroutine (empty for now, but should soon become a carddav server)
• the CardDAV testsuite is run (using python2, via a nix flake)
• the output is logged (and commited, to see evolution)

If only a specific test is run (go test ./testintegration -test.run=TestCardDAV), then the testsuite stops as the first error (for faster feedback) with detailed logging (for easier debugging).

Future steps:

• properly configure a CardDAV server (with the right username etc) and get a first state of the integration tests
• look at the fail tests and try to fix them, one after the other (checking with the standard, how the right behavior should be)

I make no promise of commitment for this (huge?) undertaking, but if anyone is interested in giving it a try, feel free to ping me!

PS: I also don't plan to make a merge request with this ugly hack (except if the maintainers really want this), but I plan to port the fixes (if I get to this point ^^)

That sounds great, thanks for the heads up! Yeah, unfortunately I'm not super thrilled about adding Python 2 stuff in CI. Would be very much interested in any conformance fixes though!

My current state:

1. Don't use css-caldavtest, use https://github.com/CalConnect/caldavtester instead (better organized, not so many quirks, better logging)
2. Nix is able to install unsupported software (like Python 2) and various packages (pycalendar in my case). This wasn't straightforward, but it works (and I am a beginner regarding nix).
3. It is a very deep rabbit hole... https://github.com/emersion/go-vcard/pull/35 came on the way down.
