Bug: Running all tests in a folder fails when the folder contains an nunit SetUpFixture class

[Michael Ketting]

Hi!

I have the folowing setup:
+ Folder
++ SubFolder1
------- SetUpFixture1
------- TestFixture1
------- TestFixture2
++ SubFolder2
------- TestFixture3
------- TestFixture4

When I try to run the nunit tests in SubFolder1 using TestDriven.NET, I get the following error message: "You can't execute a namespace as an ad-hoc test."
When I run the tests in Folder or SubFolder2, everything works fine, so it appears that TD.NET has an issue with folders containing SetUpFixture classes.
Also, no problem exists with SetUpFixture classes in the project root, i.e. when running the tests on the entire project instead of a single namespace.

Hi Michael,

This is a side effect of how TestDriven.Net executes its tests. Rather
than crawl the target assembly looking for tests, both the discovery
and execution of tests is delegated to the plugin test runners.
TestDriven.Net passes a test path to the test runner, rather that a
complete list of tests to be executed.

When a subfolder is targeted, TestDriven.Net looks at the first class
in each of the contained source files. If all of the classes are in
the same namespace, the test runner will attempt to execute all tests
in the target namespace. If the classes are in mixed namespaces, it
will attempt to execute the first class in each source as a separate
test run (which can be very slow).

To make this work, try to ensure that all of your test classes for a
given folder are in the same namespace. Also, try putting the test
class first in the source file followed by any utility classes you're
using.

I know this setup isn't ideal, but changing it as this stage would be
very tricky.

Regards,
Jamie.

Hi Jamie!
Thanks for the quick response!

Considering your explanation, my sample was probably illconceived. I also run into this problem when I have test fixtures before the setup fixture, alphabetically speaking. Each class is in an individual source file. And all classes belong to the same namespace. So, if I understood you correclty, it should work in those cases?

If needed, I could mock up a short sample project.
