System.NullReferenceException when running NUnit tests #653

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.  Open a solution containing NUnit tests
2.  Hit Ctrl+R, A to run all the unit tests in the solution
3.  View Test Output and note the NullReferenceException

What is the expected output? What do you see instead?
Expected output/action is for tests to run correctly, as happens in the 
standalone Gallio Test runner, TestDriven.NET and NUnit GUI.  Actual output 
is a System.NullReferenceException in Gallio:

[error] An exception was thrown while finishing the population of the NUnit 
test model.
    Details: System.NullReferenceException: Object reference not set to 
an instance of an object.

FWIW, I also have UAC enabled to the default Windows 7 setting (Notify me only 
when 
programs try to make changes to my computer).  My user account is a domain 
account, 
with local administrator privileges.

Could you please provide a sample that causes the error?

I'd prefer not to send the problematic solution itself as it's not open-source 
code.  I tried to put together 
a sample project to demonstrate it, but failed to do so: the tests wouldn't run 
in Visual Studio and a 
message appears in the VS status bar explaining that "No tests were run because 
no tests are loaded or the 
selected tests are disabled".  I did a spot of digging, and for some reason, 
the Gallio plug-in "Visual 
Studio Integration Shell" isn't loading properly, and other plugins dependent 
on it then also fail.  Here's 
Gallio's reason for disabling this plugin:

> The plugin enable condition was not satisfied: '${process:DEVENV.EXE} or 
${process:VSTESTHOST.EXE} or 
${process:QTAGENT.EXE} or ${process:QTAGENT32.EXE} or ${process:QTDCAGENT.EXE} 
or ${process:QTDCAGENT32.EXE}

As an aside, would it be possible for the box on the Gallio Control Panel that 
displays that information to 
support copying its contents? Typing it out is a bit of a drag...

In the problematic solution I can invoke a test run attempt using Ctrl+R,T but 
I get the exception thrown 
above and the same status bar message.  The Gallio Control Panel reports the 
same problem with the plug-ins.  
Subsequent attempts to invoke a test run fail with the same status bar message; 
if I do a build and then 
attempt another test run, the exception and status bar messages are displayed 
again.  

I've tried reinstalling Gallio a couple of times, made no difference.

Does that help at all?  Sorry to be cagey with the sample.

Not sure this is directly related, but a very similar issue occurs with MBUnit 
tests launched from our MSBuild process. We're running Gallio version 3.1 as 
shown in log messages below. After encountering this error, we usually just 
restart the build process from Team City and the error disappears....
