Description Jon Goldberger [MSFT] 2014-11-13 12:54:31 UTC
## Steps to reproduce

1. Load the test project from github repo at https://github.com/teyc/IosUnitFail
2. Run tests

Expected result: All three tests pass

Actual result: no tests are run. Fails with:

Internal error
RemotingException: Unix transport error.

(The stack trace shows up in the Test results window and I am unable to copy it)


#Note:

Changing the parameter type for the GetExpression method to string or int allows the tests to run and pass.

Comment 2 Ram Chandra 2014-11-17 05:01:37 UTC
I have checked this issue and with the help of bug description I am able to reproduce this issue.

I observed that when I run the attached sample I am getting the following exception. 

"RemotingException: Unix transport error."

I have also check that when I change the type of "GetExpression" method to int or string I am not getting any error/exception. When I check the test result it shows "Connection refused" message.

We had that one before:

https://bugzilla.novell.com/show_bug.cgi?id=652321

I think too that this looks like a mono issue
Comment 4 Rodrigo Kumpera 2014-11-18 11:19:55 UTC
Hi Mike,

Please extract a test case out of the unit test remoting setup that XS does so we can move to fix it on the runtime.

Comment 6 Mike Krüger 2015-01-05 07:05:47 UTC
@Rodrigo: https://github.com/teyc/IosUnitFail is fairly simple.
Comment 7 Rodrigo Kumpera 2015-01-05 10:40:45 UTC
Hi Mike,

That still requires us to debug the whole XS, doesn't it?

I'll be landing some improvements in that area into master, it might help us there.
Comment 8 Lluis Sanchez 2015-02-06 04:30:35 UTC
This is usually caused by a crash in our test runner. We need to find out how is it crashing.
Comment 9 Mike Krüger 2015-04-04 01:02:13 UTC
Works for me using mono 4.

@lluis: that crash happened with teh command line test runner as well
