An Exception occurred in an event handler #723

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Configure a gallio project to automatically run when an assembly changes.
2. Using Visual Studio 2010, rebuild your project. My project is using both 
MBUnit and NUnit, as well as SpecFlow.
3. When Gallio reloads the project, it'll run the tests. The failure occurs at 
the end of execution.

What is the expected output?
No errors.

What do you see instead?
No errors, but a dialog that tells me than an exception occurred in an event 
handler. Gallio then locks the file, so a rebuild is no longer possible in 
Visual Studio.

What version of the product are you using? On what operating system?
I'm using 3.2 build 517 on a Windows Vista OS with Visual Studio 2010. Both 
gallio and Visual Studio are running as Administrator (I thought it might be a 
permissions issue, but it didn't make any difference). In addition, I have AVG 
antivirus running in the background, but the directory where my binaries are 
going is explicitly listed in the virus scanner's exclusion list. This issue 
occurs when I am using the Isolated Process test runner factory, as well as the 
Local process.

As an additional curiosity, if I close and re-open gallio, this bug does not 
occur the first time the binaries are reloaded by rebuilding in Visual Studio 
2010, but it does occur on the second and subsequent runs. Also, when I turn 
off the generation of reports after the test run, the problem goes away (so I 
suspect it is there).

I'm generating reports in HTML format and auto-condensing when the test count 
exceeds 100 (I only have 6 tests in this project so far).

Please provide any additional information below.

This may be a red herring, but it seems to crash for me when I have the 
execution log window open...
