No, running it through the gui I can get it to give this message:

 

FIND.Spike.Application.Framework.Controls.FormattedTextBox.FormattedTextBoxT
est.PasteTest_NoFormatString:

An unhandled System.ApplicationException was thrown while executing this
test : Exception in pump thread

at NUnit.Core.EventPump.PumpThreadProc()

at System.Threading.ThreadHelper.ThreadStart_Context(Object state)

at System.Threading.ExecutionContext.Run(ExecutionContext executionContext,
ContextCallback callback, Object state)

at System.Threading.ThreadHelper.ThreadStart()

 

Though now its started crashing outright with no message at all through the
console (Nunit-console has encountered an error and must close).

The inconsistency of it all is maddening.

There's a line in your stack trace:

 

   at NUnit.Core.EventListener.RunFinished(TestResult result)

 

Is that always where the error occurs?

Subject: [Nunit-users] Exception in Pump Thread

Hey Everyone,

 

I have come across problem using NUnit that is driving me batty and I'm
hoping someone here might be able to help me.

 

We use NUnit on a continuous build server to run tests against a .Net 1.1
client application for a major project. recently I've been upgrading the
project to .Net 2.0 using Visual Studio 2008 and for the most part it's gone
smoothly - everything except the build and tests.

 

We use a number of extra libraries in testing, such as EasyMock .Net and
NUnitForms.  During the upgrade we had to ditch EasyMock (hasn't been
updated since 2004 and doesn't support anything > 1.1) and I've recompiled
NUnitForms once again to link to the correct NUnit dll.  I replaced EasyMock
with NMock 2 and most everything works, the tests all pass, everything is
hunky dory. 

 

Except that if I run the test in the gui or the console, I get a series of
intermittent errors.  Which one I get seems to depend on how I run (the
entire build process, just the unit tests, the unit tests minus some of them
etc).  

 

One of the main ones I get is this: 

 

Unhandled exceptions:

1)  : System.ApplicationException: Exception in pump thread --->
System.Runtime.Serialization.SerializationException: The object with ID 3
was referenced in a fixup but does not exist.

   at NUnit.Core.EventPump.PumpThreadProc()

   at System.Threading.ThreadHelper.ThreadStart_Context(Object state)

   at System.Threading.ExecutionContext.Run(ExecutionContext
executionContext, ContextCallback callback, Object state)

 

 

I get it both at the console and in the gui runner.  The strange thing is
it's not actually an error in any of the tests - if I run it in the gui all
tests show green, and this exception is thrown as the last thing that
happens.  The same thing happens in the console.

 

A really odd behaviour is if I run a small subset of the tests, in this case
ones running tests on certain custom controls.  If I run each control
fixture separately, they all pass green.  If I run them all together, they
all pass green but throw this error after running.  

 

It's also intermittent.  I thought it have gone away a while ago when I ran
the tests and they all worked fine, but the error came back on the next
pass.

 

I originally upgraded to 2.4.8, but as I was getting this error (as well as
"Out of memory" occasionally, and sometimes just a straight crash with no
explanation), I upgraded again to 2.5 alpha 3.  It hasn't made any
difference or change.

 

I've got this week to evaluate how much effort it will take to migrate this
app to 2.0, it seems strange that the main thing holding us back should be
the test interface.  I'd hate to have to shut off all the tests completely
to make this upgrade happen, but it's looking like that might be the only
option.  I'm fervently hoping someone on this list has come across this
problem before.

Thanks for your time, all.
