This keeps happening. We should have the test at least tell us which thread it is.

Got one: https://github.com/http4s/http4s/pull/5028/checks?check_run_id=3262369056 /cc @isomarcte

@rossabaker do you think that is a default HTML error page? I should have re-written those better, to dump the whole output on failure.

[rossabaker]

I just looked at the test name when I pinged you, and now GitHub can't find the log. 😩

[isomarcte]

@rossabaker the string it was matching was something like <doctype

[rossabaker]

Yep, sounds like. The default Tomcat error pages are all HTML.

Here's another one

==> X org.http4s.tomcat.server.TomcatServerSuite.server should route requests on the service executor  6.272s munit.ComparisonFailException: /home/runner/work/http4s/http4s/tomcat-server/src/test/scala/org/http4s/tomcat/server/TomcatServerSuite.scala:101
100:      .map(_.take(prefix.size))
101:      .assertEquals(prefix)
102:  }
values are not the same
=> Obtained
<!doctype htm
=> Diff (- obtained, + expected)
-<!doctype htm
+http4s-suite-

It's probably the response timing out because we still ask too much of these free CI boxes.
