Description Gleb 2013-07-09 12:49:17 UTC
Hello!

I tried to write unit tests for my iOS app using this tutorial http://docs.xamarin.com/guides/ios/deployment,_testing,_and_metrics/touch.unit
But I can't add a reference from test project to devel project since it says "Cannot reference exe projects"

How to reproduce:

1. Create new iOS project (Master)
2. Create new iOS tests project (test)
3. Test project-> References->Edit References
4. Select "Project" in opened window.
Result: You can't select Master project due to "Cannot reference exe projects"
Expected: You can refer the Master project

It is kind a bug/or/feature issue but reference to the working project is pretty common way. I don't want to create dll every time I want to run tests.

That's an IDE restriction -> Xamarin Studio

OTOH, without the restriction, you'll likely hit another issue. The (unit test) application will try to register "AppDelegate" multiple time with the ObjC runtime. That will fail in some scenarios (e.g. the static registrar won't allow this when running on devices).

If you really want to avoid a .dll then you can reference the exe source files inside your unit test project.

exe projects are meant to produce native executables, not nunit testable assemblies.

 -> Xamarin.iOS issue

Probably should have explained why I reassigned.

The sample unit test project builds fine in XS and deploys to device, but all of the tests (seems to be only 1 test, actually) fail.

No idea why.
Comment 8 Rolf Bjarne Kvinge [MSFT] 2014-01-31 12:30:33 UTC
That test is failing because it can't find an image.

That image's Build Action is BundleResource - which means it will be copied to the .app directory of its project (the main project).

The unit test project only references AppProject.exe, and the image file isn't connected at all to the .exe, so the image will not be copied to the unit test .app directory.

You'll have to manually include the image (with the corresponding directory) in the unit test project for this to work.
