Hey @hughbe, are you still planning on working on this ? If yes, could you rebase on main to include my PR #9471 which should fix the WindowsBase conflict that you saw and other errors that you would have gotten at build and runtime.

I pulled your changes locally and ran the tests. Rebased on main and with a couple of other infra changes, the tests were running and the failures seemed specific to the code. Let me know and I'll send you my changes.

Hi there - yes I am planning on advancing this. I will try to do so this week!

Hey @hughbe, I was able to repro locally and I opened a PR to fix it #9534.

Could you also fix the configuration mapping of WindowsBase.Tests.csproj in the solution (You just need to remove and re-add WindowsBase.Tests.csproj in the solution).

ThomasGoulet73 · 2024-09-07T04:08:20Z

Hey @hughbe, could you rebase on main ? My PR #9471 was merged in main today and it should fix the errors you are seeing.

I pulled your branch locally and I was able to run the tests. There's a couple more things that needs fixing in your PR:

You need to fix the configuration mapping of WindowsBase.Tests.csproj in the solution (You just need to remove and re-add WindowsBase.Tests.csproj in the solution, it will handle the mapping automatically).
Some tests are failing on my machine. Some of these test failures is because they depend on the current culture and they fail on my machine because they expect the result to have "," as the "List separator" in the culture settings while mine is ";" (ca-FR).

@hughbe any chance you'll have a few to rebase this again? I'll try to advocate for this on our side. @lonitra want to make you aware of this.

hughbe · 2024-12-10T22:56:19Z

@JeremyKuhne would you like me to rebase with or without the changes to remove the invalid debug asserts that crash the tests?

JeremyKuhne · 2024-12-10T23:21:30Z

@hughbe I don't have a strong opinion either way. I've added the NoAssertContext to the shared test assembly if that will help you any. dotnet/winforms#12621 It should show up in WPF in a couple days.

@hughbe, I was trying to debug the tests further, and although the tests run without any issues when ran via Test Explorer in Visual Studio, but when we run them using CLI using the following command

.\build.cmd -plat x64 -test

the tests that are meant to test classes derived from WeakEventManager, like CollectionChangedEventManagerTest, CurrentChangedEventManagerTests, WeakEventManagerTTests are crashing with unhandled exceptions with the following error message

Exception Info: System.InvalidCastException: Unable to cast object of type 'MS.Internal.NamedObject' to type System.ComponentModel.ICollectionView

or an invalid cast exception to some other type depending on the tests. On looking further found that the NamedObject has the _name parameter set to StaticSource.

I am looking more into this, but would like to know if you have some more inputs on this.

UPDATE : I am guessing this has something to do when we are passing null as the source, when adding listeners to WeakEventManager and subclasses.

wpf/src/Microsoft.DotNet.Wpf/src/WindowsBase/System/Windows/WeakEventManager.cs

Line 261 in fa10a71

object sourceKey = source ?? StaticSource;

UPDATE 2 : Here is a commit disabling a few tests which fixes the InvalidCastException : e9429c4

hughbe · 2025-01-09T20:58:49Z

Hi there. Sorry for the terrible feedback loop from me on this! I’ve been moving home and haven’t been able to dedicate the sort of time it deserves.

my initial theory is that there could be a bug in WPF where we’re forcing a cast to some sort of internal class that end users can’t instantiate (w/o reflection)

a fix could be to add if (x is NamedObject o) around the cast?

I am not sure about what is the right fix for this right now.

However at this moment, I think it would be best to disable the few tests and take them up as a separate issue. I tried disabling a couple of them in this commit : e9429c4 and did not ran into the exception.

Hi there. Sorry for the terrible feedback loop from me on this! I’ve been moving home and haven’t been able to dedicate the sort of time it deserves.

That's okay, nothing to worry about. We haven't been good at it either. 😅

dipeshmsft · 2025-01-13T04:47:54Z

@hughbe, what are your thoughts on disabling the 5-6 tests ? If you are okay with it, I can push a commit disabling those tests and move the PR ahead.

hughbe · 2025-01-13T09:04:51Z

Yes, let's go ahead with that thanks

…tion test

…entException test

h3xds1nz · 2025-01-13T19:02:27Z

@dipeshmsft whole DRM doesn't work afaik so u might as well disable the tests to it.

#9855 (comment)

dipeshmsft · 2025-01-13T19:03:11Z

@h3xds1nz DRM ?

h3xds1nz · 2025-01-13T19:03:58Z

@dipeshmsft The SecureEnvironment thing with RightsManagementTransform stuff. Basically stuff that requires PresentationHost

dipeshmsft · 2025-01-13T19:23:50Z

The tests are still working for that area so I am not removing other tests. However there is a Dispatcher test failing which may need disabling for now.

h3xds1nz · 2025-01-13T19:30:53Z

@dipeshmsft Ye I see, as for the failing test it needs to be [WpfFact] so its run in the context with Dispatcher.

dipeshmsft · 2025-01-13T19:37:39Z

@h3xds1nz, but it worked this time. It is kind of flaky.

And everytime just the first test fails in the DispatcherTests class.

@hughbe, any comments on this ?

I am thinking of keeping it this way, if the failure happens for multiple PRs then I will disable the CurrentDispatcher_Get_ReturnsExpected test and check.

@h3xds1nz, but it worked this time. It is kind of flaky.

I reproduced it locally multiple times; FromThread_CurrentThread_ReturnsExpected as well is retrieving dispatcher from current thread, well of course this will be null if there's no dispatcher for the thread, which is gonna be the case if this test runs first on the thread. WpfFact ensures this will be STA thread with proper context, so we should adjust it before commiting.

I'm currently dealing with a race condition in System.Xaml tests from previous batch; we should make sure the tests are stable as well.

In that case, I should update all the tests in DispatcherTests to WpfFact and WpfTheory .

h3xds1nz · 2025-01-13T19:56:05Z

Yeah, in the DispatcherTests case we should. I went through them briefly and don't think there's one that shouldn't.

dipeshmsft · 2025-01-15T08:03:36Z

Thanks @hughbe for these tests, this is a great addition to our CI testing test suites.
Thanks @h3xds1nz @lonitra for your help on this PR.
I will be opening an issue to track all the disabled tests so that we can discuss and work to reenable the tests.
