Bug: Can't change inputs of components with zoneless change detection

[jahusa02]

Description of the bug

I'm using Angular 20.2 with vitest through analogjs plugin.
We recently made the switch to zoneless because its promoted stable.
When rendering Components through the MockRenderFactory and passing input values via a props object (like its mentioned in the docs), changing the props and run fixture.detectChanges() where sufficient to trigger changeDetection in zonefull.

With zoneless this doesn't work anymore. Tried with fixture.whenStable() and fixture.whenRenderingDone(), ngMocks.input() and setInput from the componentRef, but no luck. Also tried simple MockRender.

Only running fixture.changeDetectorRef.markForCheck will trigger change Detection.

When trying this with TestBed.createComponent it will work like expected when setting Input via setInput, so I guess this is related to how the MockRender works but idk.

Maybe I'm doing something wrong

Thanks in advance

@jahusa02 You’ll be more likely to get answers if you add a minimal test case (code) to the issue. It helps others understand how you are setting up your test cases

I have no problem using detectChanges with a zoneless app, albeit I don't use mockrenderfactory. So I'm guessing you are right that there is a bug somewhere, but if yo uwould share some code, we could perhaps help you identify what can be done to fix it, even temporarily.

I,ll try to create a minimal repo by next week

I stumbled upon the same issue with Karma/Jasmine and MockBuilder/MockRender. Worked before going zoneless.

NOTE: The goal here is to add support and coverage for zoneless projects.
