Are you creating the object used to read excel files separately for
each test or just once for
the test fixture? Normally, you should try to create it only once (in
your setup) and make sure
it is destroyed in teardown. If you are not doing this, give it a try.

The stack seems to indicate that the excel server is not available for
connection. If this is
happening with the second test to run, then you may want to set up the
connection only
once (in testfixturesetup) and maintain it through all the tests. Try
it this way as well.

I assume you have arranged to be running in the STA, since this involves
COM.

2.5.5 x64 net-4.0 crash

You received this bug notification because you are a member of NUnit
Developers, which is subscribed to NUnit V2.

Status in NUnit V2 Test Framework: New

Bug description:
Running x64 based unit tests on x64 Windows Server 2008 R2. Get the following crash from VS2010 automating Nunit.exe.
Testing Office 2010 Excel reading with x64 drivers. Running a single test works ok. Running a set of Excel tests causes the application crash. I suspect MS bug in the x64 data drivers, but this is the offending nunit test.


'   Sheet Name and Row/Column Reference
        Console.WriteLine(String.Format(cNunitMessage, "Sheet Name and Row/Column Reference"))
        objDS = objExcel.GetDataSet(System.IO.Path.Combine(GetCurrentPath, "TestData\WithDataInSheet1.xlsx"), "Sheet1$B2:D10")
        If objDS.Tables.Count = 0 Then
            Assert.Fail("No data returned")
        End If

If I run the nunit test by itself it works as expected. If I run all the tests in the nunit class it fails and crashes Nunit. The crash sends a lot of information to Microsoft.
