Code Review

This pull request successfully removes material.dart imports from focus_traversal_test.dart and linked_scroll_view_test.dart by introducing custom test utilities in widget_test_utils.dart. This is a positive change that improves the modularity and reduces dependencies in the test suite, aligning with the goal of isolating widget tests from specific design systems. The new widget_test_utils.dart file provides generic replacements for MaterialApp, MaterialPageRoute, MaterialPage, ElevatedButton, TextButton, and Colors.primaries, allowing the tests to function correctly without relying on the Material Design library. The removal of TestRoute and Divider further cleans up the test code.

Just some quick questions, otherwise looks good.

@justinmc I noticed that there are many versions of TestPage classes in tests. Do I file a follow-up issue to address that?

Yes that would be great! I guess you're planning to create one reusable class in your utils file?

justinmc

LGTM 👍

Heads up that there's an analyzer failure here.

navaronbracke · 2026-01-20T18:09:18Z

I'll take a look!

navaronbracke · 2026-01-30T14:21:49Z

Since we now have TestWidgetsApp, I will update this PR directly

navaronbracke · 2026-01-30T14:38:01Z

@justinmc We can do this file in one PR now that TestWidgetsApp is done

justinmc

LGTM 👍

-        await tester.pumpWidget(
-          WidgetsApp(
-            color: Colors.white,
-            onGenerateRoute: (RouteSettings settings) => PageRouteBuilder<void>(
-              settings: settings,
-              pageBuilder:
-                  (
-                    BuildContext context,
-                    Animation<double> animation1,
-                    Animation<double> animation2,
-                  ) {
-                    return const Placeholder();
-                  },
-            ),
-          ),
-        );
+        await tester.pumpWidget(const TestWidgetsApp(home: Placeholder()));


What a clear win for TestWidgetsApp here.
