Hi,

My company has recently upgraded to visual studio 2008 and we are in the
process of migrating our unit tests from NUnit to MSTest. We have
approximatly 4000 unit tests across 12 test assemblies in our solution.

I have migrated all the test assemblies across to mstest and the solution
compiles with no difficulties. However when i open the TestView window the
devenv.exe procees immediatly starts using 50% of CPU usage, 500Mb of
physical memory and 600Mb of virtual memory and the IDE seems to hang, after
about 5 mins the IDE crashes, or, I receive a Message Dialog over the IDE
containing "Target Invocation Exception" with an OK button.

The steps that i have taken to try and overcome this have included:

- Manually transforming the assemblies from C# class library projects to C#
Test Projects
- Completely recreating the Test projects
- Created a completely new solution and rebuilding new Test Projects

All with the same results.

Also, if I run MSTest from the command line over the solution, all test pass
with no problems.

Can you please provide some guidence as to what may be causing this problem
and how i can overcome it?

Thanks

Daniel

Hello Danielm,

According to your description, you faced an issue that VS 2008 IDE crashed
in MSTest, but in command line MSTest works fine. If I misunderstood
anything here, please don't hesitate to correct me.

IDE crash/hang issues are difficult to track on newsgroup. I suggest you
may consider creating new library project and unit test on this assemble.
Thereby, we can confirm if this is a project specific issue or VS IDE
issue. Moreover, I'm afraid to say the error "Target Invocation Exception"
doesn't help. Actually, we need more detailed information to start
investigating. Have you checked Application Event log? Is there any error
log in it?

Please feel free to let us know if you have any more concern. We are glad
to assist you.
Have a great day,
Best regards,

Wen Yuan

Hi Wen,

I have found that if i create a small solution with a project then
everything works fine, or if i create a solution and only add a subset of my
test projects it is fine. My problem seems occur as i add more test projects
to the solution. When i seems to reach about 3000 tests then the IDE will
hang.

Each time that the IDE crashes i have been sending the Error Report to
microsoft... When i look at the report myself each time there seems to be a
reference to the System.Drawing Assembly ( none of my projects reference the
System.Drawing Assembly ).

Hello Daneil,
Thanks for your reply.

I believe VS IDE calls System.Drawing dll to draw test tasks on UI.
However, in command line, MSTest doesn't need to draw anything in UI. This
is why it works fine. This sounds like a VS IDE issue. Is it possible for
you to send me the Error Report when VS IDE crashes? My email address is
v-wywang@microsoft.com. I'm willing to investigate on it.

Please feel free to let me know if you have any more concern. We are glad
to assist you.
Have a great day,
Best regards,
Wen Yuan
