This pull request introduces a new "Triggers Feature Matrix" to the test cases host app, providing a comprehensive set of pages and view models to explore, demonstrate, and test various trigger types in .NET MAUI. The main changes include the addition of new pages for triggers, a robust view model supporting multiple trigger types, supporting converters and trigger actions, and updates to the test categories.

New Triggers Feature Matrix:

Added a new entry for "Triggers Feature Matrix" to the list of gallery pages in CorePageView.cs, making the new triggers demo accessible from the app's main navigation.
Introduced TriggersControlPage, TriggersControlMainPage, and TriggersOptionsPage (with XAML and code-behind), providing navigation, UI, and options for selecting and demonstrating 10 different trigger types. This includes logic for resetting state, updating UI based on device orientation and platform, and handling navigation between pages. [1] [2] [3]
Added TriggersViewModel to manage state and behavior for all trigger demos, including properties for each trigger type, input validation, and reset logic. Also introduced several value converters and trigger actions (e.g., FadeTriggerAction, NumericValidationTriggerAction, and string converters) to support advanced trigger scenarios in the UI.
Added a new test category constant Triggers to UITestCategories, enabling automated or manual test tagging for the new triggers feature matrix.

These changes collectively provide a robust foundation for testing and demonstrating trigger functionality in the MAUI controls test suite.

PR Summary

This PR introduces a comprehensive "Triggers Feature Matrix" to the .NET MAUI test suite. It demonstrates and tests 10 different MAUI trigger types:
background color change)
button enabled state)
numeric validation)
button enabled)
fade animations)
grid background via VisualStateManager)
layout orientation)

Exhausted: N/A
Selected Fix: PR's approach - This is a pure test addition PR. There is no bug fix to improve upon or replace. try-fix exploration is not applicable.

Reason try-fix was skipped

This PR adds new test coverage (HostApp pages + UI tests) for MAUI trigger functionality. There is no existing bug being fixed. The try-fix skill requires:

A broken baseline (reverting a bug fix to get failing tests)
Alternative fix ideas to explore

Neither applies here. The Gate verification confirmed all 17 tests pass with the current code.

Summary

PR #34152 adds a comprehensive "Triggers Feature Matrix" to the MAUI test suite, covering all 10 major MAUI trigger types with 17 NUnit UI tests and screenshot baselines for Android, iOS, Mac, and Windows. This is a pure test addition PR (community contribution from Syncfusion) with no bug fix involved.

Gate All 17 tests passed on iOS (iPhone Xs, iOS 18.6)PASSED :

What Was Tested

10 trigger types: PropertyTrigger, DataTrigger, EventTrigger, MultiTrigger, EnterActions/ExitActions, StateTrigger, AdaptiveTrigger, CompareStateTrigger, DeviceStateTrigger, OrientationStateTrigger
17 tests covering both screenshot verification and behavioral assertions
Platform: iOS (as specified; Android/Mac/Windows snapshots also included in PR)

Root Cause

N/ This PR adds new test coverage, not a bug fix.A

Fix Quality

The test infrastructure is well-implemented:

Strengths:

Follows established NavigationPage-based FeatureMatrix pattern (consistent with BorderControlPage, ButtonControlPage, etc.)
Uses UITestEntry (cursor-hidden) for stable screenshot comparisons
Proper event subscription/unsubscription in OnAppearing/OnDisappearing
VerifyScreenshotOrSetException collects failures across multi-step tests
State reset logic when returning from options (_isReturningFromOptions flag + ViewModel.Reset())
Binding.DoNothing returned from one-way converter ConvertBack methods
Platform exclusions via #if TEST_FAILS_ON_* match established patterns
All 6 Copilot review suggestions addressed by the author

Minor Observations (non-blocking):

OrientationStateTrigger excluded on Android without issue The #if TEST_FAILS_ON_ANDROID comment says "currently failing on Android in Automation, but can be passed manually." Most #if TEST_FAILS_ON_* exclusions in the codebase reference a GitHub tracking issue. Consider adding one to track the Android automation failure.link
No orientation cleanup on test AdaptiveTriggerChangesOrientation calls App.SetOrientationLandscape() but only restores portrait at the end (not in a finally block). If the test throws between the two orientation calls, subsequent tests run in landscape. This matches patterns elsewhere in the codebase but could cause test flakiness.exception
XAML Title is " The TriggersControlMainPage XAML has Title="TriggersControlPage" instead of something more user-friendly like "Triggers Feature Matrix". This is cosmetic only and doesn't affect tests.TriggersControlPage"

Try-Fix Results

Not This is a pure test addition PR with no bug fix to compare against.applicable

PR Title & Description Accuracy

The PR title "[Testing] Feature Matrix UITest Cases for Triggers" accurately reflects the implementation. The description correctly describes all new components added.

Conclusion

The implementation is thorough, consistent with established FeatureMatrix patterns, and all tests pass on iOS. The community contribution demonstrates good understanding of the MAUI test infrastructure. The minor observations are informational and don't block merge.

Title: ✅ Good

Current: [Testing] Feature Matrix UITest Cases for Triggers

Description: ✅ Good

Description needs updates. See details below.

Code Review: ✅ Passed

Code Review – PR #34152: Triggers Feature Matrix UI Tests

🟡 Suggestions

1. `PropertyChanged` event not declared nullable

File: src/Controls/tests/TestCases.HostApp/FeatureMatrix/Triggers/TriggersViewModel.cs

// Current
public event PropertyChangedEventHandler PropertyChanged;

// Should be
public event PropertyChangedEventHandler? PropertyChanged;

The event is invoked with the null-conditional operator (?.Invoke), but the declaration itself is not marked nullable. With nullable reference types enabled, this can produce a CS8618 warning. Declaring it as PropertyChangedEventHandler? is the correct pattern.

2. `PushAsync` called without `await` in constructor

File: src/Controls/tests/TestCases.HostApp/FeatureMatrix/Triggers/TriggersControlPage.xaml.cs

public TriggersControlPage()
{
    _viewModel = new TriggersViewModel();
    PushAsync(new TriggersControlMainPage(_viewModel)); // fire-and-forget
}

Calling PushAsync in a constructor without await is a fire-and-forget async operation. While this is an established MAUI pattern for NavigationPage subclasses and works in practice, any exceptions during navigation are silently swallowed. This is very common in the codebase (many existing feature matrix pages use this same pattern), so it's low-risk here, but worth noting.

3. Inline `#if` in test helper methods

File: src/Controls/tests/TestCases.Shared.Tests/Tests/FeatureMatrix/TriggersFeatureTests.cs

private void VerifyScreenshotOrSetExceptionWithCroppingBottom(ref Exception? exception, string? name = null, bool isKeyBoardNotShown = false)
{
#if IOS
    VerifyScreenshotOrSetException(ref exception, name, cropBottom: CropBottomValue, tolerance: 0.5, retryTimeout: TimeSpan.FromSeconds(2));
#elif ANDROID
    if (isKeyBoardNotShown)
        VerifyScreenshotOrSetException(ref exception, name, tolerance: 0.5, retryTimeout: TimeSpan.FromSeconds(2));
    else
        VerifyScreenshotOrSetException(ref exception, name, cropBottom: CropBottomValue, tolerance: 0.5, retryTimeout: TimeSpan.FromSeconds(2));
#else
    VerifyScreenshotOrSetException(ref exception, name, tolerance: 0.5, retryTimeout: TimeSpan.FromSeconds(2));
#endif
}

The UI testing guidelines discourage inline #if directives, preferring platform-specific logic in extension methods. However, here the #if is in private helper methods (not test method bodies), which is an acceptable compromise – it keeps the test method bodies clean and readable. No action required, but be consistent with this pattern across the feature matrix tests.

4. Missing newline at end of `UITestCategories.cs`

File: src/Controls/tests/TestCases.Shared.Tests/UITestCategories.cs

The diff shows \ No newline at end of file. The file should end with a newline. This is a minor style issue that can be fixed trivially.

5. `OrientationStateTriggerShowsCorrectBackground` only runs on iOS

File: src/Controls/tests/TestCases.Shared.Tests/Tests/FeatureMatrix/TriggersFeatureTests.cs

#if TEST_FAILS_ON_CATALYST && TEST_FAILS_ON_WINDOWS
#if TEST_FAILS_ON_ANDROID  // excluded from Android, Catalyst, Windows → iOS only
    [Test]
    [Order(7)]
    public void OrientationStateTriggerShowsCorrectBackground()

The comment says "failing on Android in Automation, but can be passed manually." This means the test only runs on iOS. The comment makes the reasoning clear, which is good. No action required – document this known limitation so it can be revisited when the Android issue is resolved.

6. `TriggersControlPage` and `TriggersControlMainPage` naming could be confusing

File: src/Controls/tests/TestCases.HostApp/FeatureMatrix/Triggers/TriggersControlPage.xaml.cs

TriggersControlPage is a NavigationPage wrapper; TriggersControlMainPage is the actual ContentPage content. The XAML file is named TriggersControlPage.xaml but its x:Class is TriggersControlMainPage. This is slightly confusing – the file name suggests a single page but it contains two classes. Consider splitting into separate files in a follow-up, or at least adding a comment explaining the architecture.

✅ Looks Good

[Category(UITestCategories.Triggers)] at class level – correct per guidelines; no per-test category attribute needed.
Snapshot coverage – snapshots provided for all 4 platforms (Android, iOS, iOS-26, Mac, Windows).
OnAppearing/OnDisappearing event management – DeviceDisplay.Current.MainDisplayInfoChanged and SizeChanged are properly subscribed and unsubscribed, preventing memory leaks.
SelectTriggerType helper method – clean, reusable navigation helper used by all tests.
retryTimeout: TimeSpan.FromSeconds(2) on all screenshot assertions – follows best practices for handling animation timing.
VerifyScreenshotOrSetException pattern – uses the deferred-exception pattern (collect, then throw) correctly to ensure all screenshots are captured before failing.
Gallery registration in CorePageView.cs – correct single-line addition following existing pattern.
ui-tests.yml category registration – Triggers added to the test run matrix correctly.
10 trigger types covered – PropertyTrigger, DataTrigger, EventTrigger, MultiTrigger, EnterExitActions, StateTrigger, AdaptiveTrigger, CompareStateTrigger, DeviceStateTrigger, OrientationStateTrigger.
Reset() called on returning from options – proper state cleanup between test runs.

Thank you! This pull request introduces a new "Triggers Feature Matrix" to the test cases host app, providing a comprehensive set of pages and view models to explore, demonstrate, and test various trigger types in .NET MAUI. The main changes include the addition of new pages for triggers, a robust view model supporting multiple trigger types, supporting converters and trigger actions, and updates to the test categories. **New Triggers Feature Matrix:** * Added a new entry for "Triggers Feature Matrix" to the list of gallery pages in `CorePageView.cs`, making the new triggers demo accessible from the app's main navigation. * Introduced `TriggersControlPage`, `TriggersControlMainPage`, and `TriggersOptionsPage` (with XAML and code-behind), providing navigation, UI, and options for selecting and demonstrating 10 different trigger types. This includes logic for resetting state, updating UI based on device orientation and platform, and handling navigation between pages.

Also introduced several value converters and trigger actions (e.g., `FadeTriggerAction`, `NumericValidationTriggerAction`, and string converters) to support advanced trigger scenarios in the UI. * Added a new test category constant `Triggers` to `UITestCategories`, enabling automated or manual test tagging for the new triggers feature matrix. These changes collectively provide a robust foundation for testing and demonstrating trigger functionality in the MAUI controls test suite. https://github.com/user-attachments/assets/25c3652b-e1bf-4922-a606-e68459543f9d --------- Co-authored-by: Jakub Florkowski <42434498+kubaflo@users.noreply.github.com>
