Sytests:

    × Invited user can reject invite over federation several times
    × Test that we can be reinvited to a room we created

× Invited user can reject invite over federation several times seems to be passing:

Running tests/30rooms/06invite.pl shows:

Test 5 Invited user can reject invite over federation several times... OK

Hi! I'd like to work on this issue I'm new to dendrite, but so far i think i have a good idea where to start

Ok, so I'm in no way an expert in perl, but it seems to me that the test in question, tests/90jira/SYN-442.pl, is requesting /_matrix/client/r0/events to check whether user b even got the invite from user a. The logs of the test back this up. Since, as far as I understand, dendrite doesn't implement this, the test fails here, before user a even leaves the room it created. The test never gets to the point to actually check whether user a can rejoin the room after leaving it:

[...]
# Starting server-1
[...]
# Started server-0
  ok 1 User A created a room (Test that we can be reinvited to a room we created)
  ok 2 User A set the join rules to 'invite' (Test that we can be reinvited to a room we created)
  ok 3 User A invited user B (Test that we can be reinvited to a room we created)
  1..3
not ok 1 (expected fail) Test that we can be reinvited to a room we created # TODO expected fail

Thanks for looking into this, I'll see if I can fix up these tests.
