Suggestion:

t.Run("Non-inviter user cannot rescind invite over federation", func(t*testing.T) {
t.Parallel()
//FirstcreatearoomthatBobisin. Thisissothatlaterwecan//sendamessagetotestthatBobdoesn'tseetherescission.
roomID1 :=alice.MustCreateRoom(t, map[string]interface{}{
"preset": "private_chat",
"invite": []string{bob.UserID},
})
since:=bob.MustSyncUntil(t, client.SyncReq{}, client.SyncInvitedTo(bob.UserID, roomID1))
bob.MustJoinRoom(t, roomID1, []spec.ServerName{})
//SecondroomwhichAliceandAlice2join, Alice2invitesBoband//thenAlicekickshim.
roomID2 :=alice.MustCreateRoom(t, map[string]interface{}{
