Re: nunit tests hold onto file handles after tests aredone

Hi David,
 
Yeah... if only we had a FAQ. :-(
 
NUnit does have some current problems of not releasing objects, which are
fixed in the source. Some of those /could/ relate to your file problems, but
there really is no guarantee that files not closed explicitly will be closed
between NUnit runs. This makes some kinds of applications a bit hard to
test.
 
The simplest way to do what you want for a test directory is to delete and
recreate it in SetUp or TestFixtureSetUp. In that case, it will always be
there between tests, whether they pass or not. If you additionally want to
delete some files when the tests pass, you currently have to put the delete
at the end of each test.

Subject: [Nunit-users] nunit tests hold onto file handles after tests
aredone


Thanks for NUnit. I'm new to using it, and I have a problem which seems so
common it must be a FAQ, but I don't see it mentioned anywhere...

I have a number of tests which run code that open and write to files. When
my program exits it lets go of the filelocks just fine. However, when the
tests run in Nunit GUI (and I keep the GUI up), the files are still locked,
preventing me from inspecting their contents. Every time I run a set of
tests I have to control-P to reload the project to force NUnit to flush the
objects and cause the file locks to be released. This seems like such a
common thing that I'm surprised there isn't an option "force full GC after
testing" that would cause all the objects to be disposed. Am I doing
something wrong?

On a related note, those same tests need a nice way to create a temporary
directory to write to, and delete the directory if the test passes but leave
it if the test fails. Seems like this would be pretty common, but I couldn't
find any methods or addons that do this. Am I looking in the wrong places?

Thanks! (and thanks for nunit)

- David
