Re: Am I Running Under NUnit?

Hi Ron,
 
Our conversation appears to have fallen off the list - I put us back on it.
 
I'm confused... You already reference NUnit from your production code?
I'm assuming that's what we are talking about - if you want to figure out
whether your tests are running under NUnit or some other runner, that's
a different - perhaps a simpler - matter.
 
As far as being forced to use a hack: the entire notion seems like a
hack to me, and NUnit can't do anything to improve it. We can't even
hide the hack for you, since we have no general way to determine if
some arbitrary code is running under NUnit - and it would have to be
a general solution if NUnit implemented it, while you can simply do
something that works for your own particular case.
 
In fact, NUnit's lack of knowledge of where threads originate is already
a source of difficulty for us - one I hope to solve as part of the 3.0
rewrite.
 
If I'm misunderstanding something here, please let me know, but this
does not sound like a service NUnit can readily provide.

So you think it's better for me to do this hacks than for you to expose a
method?
After all, I am dependant on NUnit and reference it anyway.

Only this way, I'm forced to these ugly hacks.

Yes, your original method suffers from the same problem if threads are
involved.
 
If we exported such a function, then people would have to reference it,
making their apps 
dependent on NUnit - so no. :-)
 
Another possibility is to look at the entry assembly and see if it's
nunit.exe or nunit.console.
However, that may not work in a secondary AppDomain - I'm not sure.

The 2nd way is not perfect, because if the call is made from another thread
then its stack will not have any NUnit frames.
Is there a chance such a function can be exported from NUnit itself in some
future release?

Hi Ron,
 
The code is wrong on several levels:
 
1) Tactically, because it will fail if your test references a different
version of the framework than the one it
was built against.
 
2) Strategically, because the presense of a Test attribute doesn't have to
mean your test is running under
NUnit. However, it may be so for a particular user who never calls the tests
any other way.
 
There are two simple ways to test whether you are running under NUnit... 
 
One is to look at the friendly name of the current appdomain, which is
"domain-<project>" where <project> 
is the name of the assembly or project being executed. Obviously, this is
subject to name clashes.
 
The other - and more accurate - is to search the stack for the name of the
nunit.core assembly.

How can I implement a function AmIRunningUnderNUnit() ?
I have a logger, and I want to Log only if I'm running under NUnit.

This is a suggested solution:

But it doesn't work if the test spawns different threads and the function is
called from there.

Thanks,
Ron
