nunit console is not telling what tests got failed

I recently moved out of nunit tag and moved to exec tag to run nunit console for running unit tests.

Here is what i have in my build script:

exec program="nunit-console.exe" verbose="true" failonerror="true"> arg file="../abc.dll"/> exec>

Here is what I see in output:

task name="exec">250.0064250.0064

As you can see it did run from the durati开发者_开发问答on and I know that my tests are currently failing but my build didn't fail.

Any ideas?

To be honest: I'm clueless. We're executing NUnit console through NAnt's <exec> task, we're getting meaningful output and we're absolutely not doing anything fancy:

<exec program="C:\dev\tools\NUnit\2.5.9\bin\net-2.0\nunit-console.exe">
  <arg file="C:\foo\bar.dll" />
</exec>
