Dbus Timeout when running test/remote-test.py -v ZeitgeistRemoteAPITest

[Markus Korn]

This Timeout "error" in "testFindByRandomActorAndGet" is reproducible for me when running the testsuite

% test/remote-test.py -v ZeitgeistRemoteAPITest :(

OK

I'm not sure if this is an issue with the engine or the client, or if we are just doing sth wrong in the testcase.
I also think we should change our Baseclass for tests to always mark a test as failed when a dbus error occures.
As a side note of wiredness, I don't get this timeout message when only running this testcase

% test/remote-test.py ZeitgeistRemoteAPITest.testFindByRandomActorAndGet
.

OK

I debugged this further, it is not ZeitgeistRemoteAPITest.testFindByRandomActorAndGet which is producing the timeout, it is ZeitgeistRemoteAPITest.testDeleteEvents.

[Markus Korn (thekorn)]

The more I look into it the more issues I see ;)
There are two issues you can see in the description of this bug:
 1.) testDeleteEvents is timing out, but the testcase is marked as Ok (aka no failure, but a timeout won't be ok)
 2.) testFindRelated indicates an AssertionError, but the test is also marked as Ok.

I will work on both issues, and attach the branch for further review.
