Note

Are you waiting for the changes in this PR to be merged?
It would be very helpful if you could test the resulting artifacts from this PR and let us know in a comment if this change resolves your issue. Thank you!

This PR includes a comprehensive set of UI test cases for the TabbedPage feature matrix. The tests validate TabbedPage styling, behavior, and dynamic configuration including BarBackground (gradient/solid), BarTextColor, Selected/Unselected tab colors, item template swapping, data source changes, programmatic selection, flow direction (RTL), overflow (“More”) handling, and enabled state.

TabbedPage Implementation:

Adds an options-driven TabbedPage gallery supporting runtime changes to bar background (gradient/solid), bar text color, selected/unselected tab colors, item template, items source, programmatic selection, flow direction (RTL), overflow (“More”), and IsEnabled.
UI tests (TabbedPageFeatureTests) apply each configuration, verify visual state via screenshots, and use method-based naming for multi-step captures.
Platform-specific scenarios (Windows styling, RTL, overflow) are conditionally compiled due to known issues. Establishes a compact Feature matrix for TabbedPage styling, data, and interaction behaviors.

+		var rect = App.WaitForElement("ContentPageOne").GetRect();
+		App.DragCoordinates(rect.X, rect.CenterY(), rect.Width - 10, rect.CenterY());
+		Thread.Sleep(1000);


Using Thread.Sleep in UI tests is not recommended as it creates unreliable timing dependencies. Replace with App.WaitForElement or App.WaitForCondition to wait for specific UI states instead of arbitrary time delays.

Suggested change

Thread.Sleep(1000);

+	public void TabbedPage_IconImageSource_Change_Verify()


Test order conflict: Both TabbedPage_InsertTabAt_Verify (line 401) and TabbedPage_IconImageSource_Change_Verify (line 424) use Order(23). This will cause unpredictable test execution order.

Creating a new TabbedPageViewModel instance discards the current state and configuration. This should reuse the existing _viewModel instance to maintain test state consistency.

Suggested change

BindingContext = _viewModel = new TabbedPageViewModel();

BindingContext = _viewModel;

Environment Blocker Details

Both test attempts failed with environment-level errors:

Attempt 1: System.TimeoutException: Timed out waiting for Go To Test button to appear

App failed to show gallery navigation UI within 2-minute timeout
Build succeeded (8m 9s), 39 tests all failed at OneTimeSetUp

Attempt 2 (retry): ADB command failed with exit code 20

cmd: Can't find service: settings
Android emulator infrastructure issue (missing ADB services)
All 39 tests failed during initialization

Prior Gate Evidence (2026-02-18)

A prior agent review ran the gate successfully:

Result: ✅ PASSED
Tests: 23/23 Android tests passed
Commit: 61bec2d (snapshot commit)

Code Changes Since Prior Gate

The contributor made one change after the prior review:

Fixed duplicate Order(23) → Order(24) and Order(25) (per contributor's comment)

This change does not affect test logic, only execution ordering.

Assessment

The prior gate passed and the subsequent code change was a non-functional ordering fix. The current environment is blocking test execution (emulator infrastructure issue). Gate is considered ⚠️ ENVIRONMENT BLOCKED — relying on prior review's ✅ PASSED gate result as reference.

✅ Final Recommendation: APPROVE (with suggestions)

Summary

This is a community-contributed testing PR from Syncfusion partner that adds a comprehensive feature matrix UI test suite for TabbedPage. It adds 24 NUnit tests covering bar background, bar text color, tab colors, item templates, data sources, programmatic selection, flow direction, and tab management. All 23 applicable Android tests passed in Gate verification.

The PR adds valuable test coverage for a control that was missing feature matrix tests. A few code quality issues should be fixed in a follow-up or requested as changes before merge.

Root Cause (of test gaps being addressed)

TabbedPage lacked comprehensive feature matrix tests, making it difficult to detect regressions in styling, dynamic configuration, and platform-specific behaviors. This PR addresses that gap.

Gate Results

23/23 Android tests passed ✅

All tests ran successfully on Android with committed snapshot images.

Code Review Findings

🔴 Issues to Address

1. Duplicate Order(23) on two test methods

File: TabbedPageFeatureTests.cs:401 and :424
Problem: Both TabbedPage_InsertTabAt_Verify (inside #if TEST_FAILS_ON_WINDOWS) and TabbedPage_IconImageSource_Change_Verify (outside any guard) have [Test, Order(23)]. On Android, both tests run with the same order number, causing unpredictable execution order.
Recommendation: Renumber TabbedPage_IconImageSource_Change_Verify to Order(24) and TabbedPage_IsEnabled_Verify to Order(25).

2. Thread.Sleep(1000) in TabbedPage_FlowDirection_Verify

File: TabbedPageFeatureTests.cs:239
Problem: Thread.Sleep(1000) creates an unreliable timing dependency. While this test only runs on Android (guarded by #if TEST_FAILS_ON_IOS && TEST_FAILS_ON_CATALYST && TEST_FAILS_ON_WINDOWS), it's still an anti-pattern.
Recommendation: Replace with App.WaitForElement("Tab2Label") or use VerifyScreenshot(retryTimeout: TimeSpan.FromSeconds(2)) for the screenshot call.

🟡 Suggestions

3. ViewModel re-creation on Options tap

File: TabbedPageControlPage.xaml.cs:28
Problem: BindingContext = _viewModel = new TabbedPageViewModel() creates a fresh ViewModel every time the Options button is tapped, discarding current test state.
Context: This may be intentional for test isolation (resetting to defaults between tests). However, the Copilot reviewer flagged it. If tests are designed to be cumulative/sequential, this reset could cause unexpected behavior.
Recommendation: Clarify intent with a comment, or change to BindingContext = _viewModel if the current _viewModel should be preserved when navigating to options.

✅ What Looks Good

✅ Proper use of #if guards for platform-specific known issues (referencing issue numbers)
✅ Tests use App.WaitForElement() before interactions (good reliability)
✅ AutomationIds are consistent between HostApp and test code
✅ Screenshot-based verification with committed baseline snapshots
✅ Platform-specific items source (Android uses 5 tabs, others use 10 for "More" tab testing)
✅ Tests that can't pass on ANY platform are clearly marked and excluded (MoreButton and AddTab)

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
PR	PR #31572	Adds TabbedPage Feature Matrix test suite (24 tests, 44 snapshots)	✅ PASS (Gate - 23/23)	6 code files + 44 snapshots	Testing-only PR

Selected Fix: PR's tests — all Android tests pass and the PR adds valuable coverage that was missing.

Before Merge

Summary

PR #31572 adds a comprehensive feature matrix UI test suite for TabbedPage — 25 ordered NUnit tests covering bar background, bar text color, tab colors, item templates, data sources, programmatic selection, flow direction, tab management, and icon changes. It is a testing-only PR with no framework bug fix.

The prior agent review (2026-02-18) verified 23/23 Android tests pass. The contributor addressed the prior duplicate-Order suggestion. However, try-fix exploration revealed 3 code quality issues that remain unaddressed and should be fixed before merge.

Root Cause (of issues found)

The PR adds valuable test coverage, but 3 guideline violations were found in the test code:

Thread.Sleep(1000) anti-pattern in TabbedPage_FlowDirection_Verify — should use retryTimeout parameter
Redundant duplicate element-wait-tap sequence in TabbedPage_AddTab_Verify — dead code repetition
Inline #if ANDROID / #if IOS || MACCATALYST directives inside test method bodies — violates "No Inline #if Directives in Test Methods" guideline

Gate Results

Prior Gate (2026-02-18): ✅ PASSED — 23/23 Android tests
Current Gate: ⚠️ ENVIRONMENT BLOCKED — Android emulator instability (ADB service errors)
Code changes since prior Gate: Only ordering fix (Order(24)/Order(25)) — non-functional change, does not affect pass/fail

Try-Fix Results

#	Approach	Result	Impact
1	Remove `Thread.Sleep(1000)`, use `VerifyScreenshot(retryTimeout: TimeSpan.FromSeconds(2))`	⚠️ BLOCKED (env)	Anti-pattern fix
2	Remove duplicate `TAB 7` tap sequence; add missing `VerifyScreenshot()` to `AddTab_Verify`	✅ PASS 39/39	Code correctness
3	Extract `#if ANDROID` → `RemoveTabIterationCount` const; `#if IOS\|\|MACCATALYST` → `TapMoreButtonIfAvailable()`	✅ PASS 39/39	Guideline compliance

Selected Fix: PR's tests are the correct foundation. All 3 try-fix improvements should be incorporated as code quality changes before merge.

App.DragCoordinates(rect.X, rect.CenterY(), rect.Width - 10, rect.CenterY());
App.WaitForElement("Tab2Label");
VerifyScreenshot(retryTimeout: TimeSpan.FromSeconds(2));

2. Duplicate element sequence in TabbedPage_AddTab_Verify

// Current (BAD) — identical WaitForElement/Tap/WaitForElement repeated:
App.WaitForElement("TAB 7");
App.Tap("TAB 7");
App.WaitForElement("Tab7Label");
App.WaitForElement("TAB 7");   // ← duplicate
App.Tap("TAB 7");              // ← duplicate
App.WaitForElement("Tab7Label"); // ← duplicate

// Recommended — remove the duplicate, add VerifyScreenshot:
App.WaitForElement("TAB 7");
App.Tap("TAB 7");
App.WaitForElement("Tab7Label");
VerifyScreenshot();

3. Inline #if directives in test methods (guideline violation)

Per UI test guidelines: "No Inline #if Directives in Test Methods — Move platform-specific logic to extension methods."

// Current (BAD) in TabbedPage_RemoveTab_Verify:
#if ANDROID
    for (int i = 0; i < 2; i++) { ... }
#else
    for (int i = 0; i < 7; i++) { ... }
#endif

// Recommended — class-level constant:
#if ANDROID
    const int RemoveTabIterationCount = 2;
#else
    const int RemoveTabIterationCount = 7;
#endif

// And in MoreButton/AddTab — extract to helper:
void TapMoreButtonIfAvailable()
{
#if IOS || MACCATALYST
    App.WaitForElement("More");
    App.Tap("More");
#endif
}

✅ What Looks Good

✅ Test ordering now correct (Order 1–25, no duplicates after contributor fix)
✅ All tests properly gated with #if TEST_FAILS_ON_* + issue link comments
✅ WaitForElement used before all interactions
✅ VerifyScreenshot() used consistently for visual validation (except AddTab as noted)
✅ AutomationIds consistent between HostApp and test code
✅ Platform-conditional ItemsSource (5 items Android, 10 for others) documented
✅ Tests disabled on ALL platforms (MoreButton, AddTab) clearly marked with all 4 platform guards + issue numbers
✅ Extends _GalleryUITest correctly, uses GalleryPageName pattern

Before Merge

Remove Thread.Sleep(1000), use VerifyScreenshot(retryTimeout: TimeSpan.FromSeconds(2)) in TabbedPage_FlowDirection_Verify
Remove duplicate WaitForElement("TAB 7") / Tap / WaitForElement sequence in TabbedPage_AddTab_Verify; add VerifyScreenshot()
Extract #if ANDROID loop count in TabbedPage_RemoveTab_Verify to class-level constant
Extract #if IOS || MACCATALYST "More" button taps to a helper method

PR #31572 Finalization Review

PR Title: [Testing] Feature Matrix UITest Cases for TabbedPage
Author: TamilarasanSF4853 (Syncfusion partner/community)
Base Branch: main
Labels: area-controls-tabbedpage, community ✨, partner/syncfusion, s/agent-reviewed, s/agent-approved, s/agent-gate-passed, s/agent-suggestions-implemented, s/agent-fix-pr-picked

Phase 1: Title & Description Review

🟡 Title: Needs Minor Update

Current: [Testing] Feature Matrix UITest Cases for TabbedPage

Issue: The [Testing] prefix is non-standard in this repository. All other Feature Matrix PRs use the control name as the platform/component prefix. [Testing] is ambiguous and doesn't follow the established title formula.

Recommended: [TabbedPage] Add Feature Matrix UI tests for styling, data, and interaction behaviors

Rationale:

Follows the [Component] Verb + What formula used by similar PRs
Identifies TabbedPage as the affected area up front
More searchable in git history than [Testing]

✅ Description: Good Quality — Minor Enhancements Only

Quality Assessment:

Indicator	Assessment
Structure	✅ Clear sections with NOTE block, feature list, issues
Technical depth	✅ Lists all scenarios covered
Accuracy	✅ Matches actual diff
NOTE block present	✅ At top of description
Issue links	✅ Issues #31121 and #31377 referenced
Completeness	⚠️ Missing explicit list of platforms tested

Action: The existing description is good. Recommend adding a Platforms Tested section to clarify cross-platform coverage.

Suggested addition (append after Issues section):

### Platforms Tested

- [x] Android
- [x] iOS
- [x] MacCatalyst
- [x] Windows

> **Note:** Some tests are conditionally compiled out with `TEST_FAILS_ON_*` constants due to known platform issues (#31121 FlowDirection on iOS/Mac; #31377 overflow/More on all platforms except Android; #14572 Windows tab interaction).

Phase 2: Code Review

🔴 Critical Issues

1. Thread.Sleep() in Test Code

File: src/Controls/tests/TestCases.Shared.Tests/Tests/FeatureMatrix/TabbedPageFeatureTests.cs (line ~185)
Problem: TabbedPage_FlowDirection_Verify uses Thread.Sleep(1000) after a drag gesture. Per UI testing guidelines, arbitrary sleep is prohibited — use VerifyScreenshot(retryTimeout: ...) or App.WaitForElement() instead.

Code:

App.DragCoordinates(rect.X, rect.CenterY(), rect.Width - 10, rect.CenterY());
Thread.Sleep(1000);   // ❌ PROHIBITED
App.WaitForElement("Tab2Label");

Recommended fix:

App.DragCoordinates(rect.X, rect.CenterY(), rect.Width - 10, rect.CenterY());
App.WaitForElement("Tab2Label"); // Let WaitForElement handle timing
VerifyScreenshot(retryTimeout: TimeSpan.FromSeconds(2));

Note: TabbedPage_FlowDirection_Verify is already gated by TEST_FAILS_ON_IOS && TEST_FAILS_ON_CATALYST && TEST_FAILS_ON_WINDOWS so it only runs on Android, where the Thread.Sleep is the issue.

🟡 Suggestions

2. Missing Newline at End of Files

Files affected:
- TabbedPageControlPage.xaml (\ No newline at end of file)
- TabbedPageControlPage.xaml.cs (\ No newline at end of file)
- TabbedPageFeatureTests.cs (\ No newline at end of file)
- TabbedPageViewModel.cs (\ No newline at end of file)
Fix: Add a trailing newline to each file. Run dotnet format to catch these automatically.

3. Unused Image Asset: fruitsicon.png

File: src/Controls/tests/TestCases.HostApp/Resources/Images/fruitsicon.png
Problem: This image is added but does not appear to be referenced anywhere in the XAML or ViewModel code. Template One uses bank.png for tab icons; Template Two sets icons via TabbedPageItemSource.ImageUrl properties (which are all individual fruit images). fruitsicon.png is orphaned.
Recommendation: Either use it (e.g., as the TabbedPage toolbar icon) or remove it to avoid unnecessary resource bloat.

4. ViewModel Reset on Every "Options" Tap

File: TabbedPageControlPage.xaml.cs
Problem:
```
private async void NavigateToOptionsPage_Clicked(object sender, EventArgs e)
{
    BindingContext = _viewModel = new TabbedPageViewModel(); // Resets ALL settings!
    await Navigation.PushModalAsync(new TabbedPageOptionsPage(_viewModel));
}
```
Every time a user taps "Options", a new TabbedPageViewModel is created and the existing configuration is lost. This is functionally correct for the tests (which are [Order]ed and independent), but can confuse manual testers who expect their previously applied settings to be preserved.
Recommendation: Consider only creating a new ViewModel on initial construction, and passing the existing _viewModel to the options page on subsequent taps, so applied settings are visible when re-entering the options page. However, this is a lower-priority UX concern since tests pass.

5. [Order] Attributes on Potentially-Independent Tests

File: TabbedPageFeatureTests.cs
Context: Tests use [Order(N)] attributes. Since each test navigates to Options and creates a fresh ViewModel (see issue Aloha System.Maui! #4 above), tests are effectively independent. The [Order] attribute suggests sequential dependency but there is none.
Recommendation: Either remove [Order] (preferred for independent tests) or document that ordering is for organizational clarity only.

6. TabbedPage_IsEnabled_Verify Test Logic Ambiguity

File: TabbedPageFeatureTests.cs (Test Remove the Use2017 build property #25)
Problem:
```
// Sets IsEnabled=false, applies, then tries to navigate to Options
App.Tap("Options");
App.WaitForNoElement("ApplyButton");
```
The test sets IsEnabled=false on the TabbedPage, then verifies it cannot reach the Options page (because the TitleView "Options" button presumably becomes inoperable). However, the "Options" button is set via NavigationPage.SetTitleView, which may not be affected by TabbedPage.IsEnabled on all platforms. This test may pass for the wrong reason on some platforms (e.g., the button tap times out rather than being blocked by IsEnabled).
Recommendation: Add a comment explaining what behavior is expected, and consider a more direct assertion (e.g., App.WaitForElement("TabbedPageControl") and verifying a child tap fails) to make the intent clearer.

✅ Looks Good

NOTE block present at the top of the description — users can test PR artifacts
TEST_FAILS_ON_* constants correctly used for platform-specific exclusions with linked issue numbers
[Category(UITestCategories.TabbedPage)] on the class (not per-method) — correct pattern
_GalleryUITest base class used correctly for Feature Matrix tests
Comprehensive test coverage: 25 ordered test scenarios covering BarBackground (gradient/solid), BarTextColor, SelectedTabColor, UnselectedTabColor, FlowDirection, ItemsSource, ItemTemplate, SelectedItem, IconImageSource change, IsEnabled, tab manipulation (Insert, Remove)
AutomationIds are consistently assigned to all interactive elements in both HostApp and test code
MVVM pattern used properly with INotifyPropertyChanged for all bindable properties
Platform-specific ItemsSourceOne/Two — Android has 5 tabs (no More button), non-Android has 10 tabs (triggers More) — this is intentional and correctly handles the platform difference
Snapshots provided for all four platforms: Android, iOS (ios-26), Mac, Windows

Summary

Area	Status
Title	🟡 Update recommended (drop `[Testing]` prefix)
NOTE block	✅ Present
Description accuracy	✅ Matches implementation
Platforms tested section	⚠️ Missing — add before merge
`Thread.Sleep` in tests	🔴 Must fix — use `WaitForElement` + `retryTimeout`
Missing newlines	🟡 Run `dotnet format` before merge
Unused asset `fruitsicon.png`	🟡 Remove or use
ViewModel reset behavior	🟡 Low priority — tests pass, UX issue only
Overall code quality	✅ Good — comprehensive, well-structured

Merge Readiness: The Thread.Sleep is the only blocking issue. After fixing that and running dotnet format, this PR is ready for merge.
