Haven’t touch NhProf for a while, this morning the error message said, the installed license for NHibernate Profiler is not valid!
After contact with Ayende, it turns out the issue is from our user profile, because if I switch to a different user, everything works smoothly.
OK, while waiting for somebody can figure out that specific user profile problem, what I can do is to use the runas command to ‘sudo’ nhprof to run under another user account.
One annoying thing is windows keep asking input password when runas starts, echo password or pipe into a text file doesn’t work. The trick is to use built-in savecred option in runas command, just type in the password once, then it will save it.
runas /savecred /user:local\nhprof c:\app\nhprof\launch_nhprof.bat
Also, the trick for waiting for nhprof to generate report when shutting down:
runas /savecred /user:local\nhprof c:\app\nhprof\kill_nhprof.bat @echo off @echo waitinging for output report generating ... :WAIT_FOR_OUTPUT if not exist c:\tmp\nhprof_Output.html ( GOTO WAIT_FOR_OUTPUT ) @echo on
Initialize NhProf in NUnit test
NhProf can be setup without changing the app code, but that assume you already have log4net hooked up in app. Our experience is setting up log4net is still more work comparing to init nhprof in unit-test code. http://nhprof.com/Learn/GettingStarted
Here is a easy way to init Nhprof in unit-test project, create a Global class with SetupFixture attribute, remove any namespace, this will ensure the setup code in this class run before any of the fixtures in the entire assembly. (NUnit doc)
[SetUpFixture]
public class Global
{
[SetUp]
public void RunBeforeAnyTests()
{
Console.WriteLine("Initializing NHibernateProfiler......");
HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize();
}
}
