Test failure in TestRTMDisconnect

[CyrilBrulebois]

What happened

While building a Debian package in a clean and minimal environment, the following test fails:

=== RUN   TestRTMDisconnect
    websocket_managed_conn_test.go:197: discarded event of type 'connection_error' with content '&slack.ConnectionErrorEvent{Attempt:1, Backoff:100000000, ErrorObj:(*url.Error)(0xc006cef920)}'

--- FAIL: TestRTMDisconnect (5.00s)

I haven't been able to pinpoint what's happening just yet, but I'd be happy to learn a little more about what the test is supposed to be checking, so that I can figure out whether some components are missing in my chroot, whether some network access is required, etc.

Expected behavior

While building the exact same Debian package in a development environment, the test passes just fine:

=== RUN   TestRTMDisconnect
    websocket_managed_conn_test.go:188: invalid auth event received
--- PASS: TestRTMDisconnect (0.26s)

Steps to reproduce

I'll update this ticket once I have published my work in progress to https://salsa.debian.org/

Versions

• Go: 1.19.2
• slack-go/slack: 0.11.3

Steps to reproduce, in a Debian environment (this doesn't need to be unstable or testing, stable is fine):

1. Generate a source package:

git clone https://salsa.debian.org/go-team/packages/golang-github-slack-go-slack.git
cd golang-github-slack-go-slack
uscan --download-current --rename
dpkg-buildpackage -S -d
cd ..

2. Create a build environment, it's Debian unstable by default:

sudo cowbuilder --create

3. Build the package in that environment:

sudo cowbuilder --build golang-github-slack-go-slack_0.11.3-2.dsc

Thanks for reporting. This is known issue. https://github.com/slack-go/slack/issues/861

Oh, my bad, that other issue didn't show up when searching for the test's name. That being said, it fails reliably for me, not just occasionally.
