 		// Interact with theme controls
 		cut.Find("select").Change("yellow");
-		cut.FindAll("button").Last().Click();
+		cut.FindAll("button")[cut.FindAll("button").Count - 1].Click();


This clicks the last button by calling FindAll("button") twice, which re-queries the rendered markup and repeats work. Store the results in a local variable (and then index [^1] / buttons.Count - 1) to make the intent clearer and avoid duplicate DOM queries.

Suggested change

cut.FindAll("button")[cut.FindAll("button").Count - 1].Click();

var buttons = cut.FindAll("button");

buttons[buttons.Count - 1].Click();

+	[Fact]
+	public void ThemeProviderWhenGetColorThrowsNonJsExceptionPropagatesException()
+	{
+		// Arrange
+		JSInterop.Setup<string>("themeManager.getColor")
+				.SetException(new InvalidOperationException("unexpected failure"));
+		JSInterop.Setup<string>("themeManager.getBrightness").SetResult("light");
+
 		// Act
 		var act = () => Render<ThemeProvider>();

-		// Assert — component renders without throwing; defaults are used
-		act.Should().NotThrow();
-		var cut = Render<ThemeProvider>();
-		cut.Instance.CurrentBrightness.Should().NotBeNull();
+		// Assert
+		act.Should().Throw<InvalidOperationException>().WithMessage("unexpected failure");
+	}


The new tests expect non-JS exceptions from JS interop (e.g., InvalidOperationException) to propagate during initial render, but ThemeProvider currently catches all exceptions in OnAfterRenderAsync and will swallow these. Either update ThemeProvider to catch only JSException (and allow other exceptions to bubble), or adjust/remove these tests to match the current implementation so the suite doesn't fail.

+	[Fact]
+	public void ThemeProviderWhenGetBrightnessThrowsNonJsExceptionPropagatesException()
+	{
+		// Arrange
+		JSInterop.Setup<string>("themeManager.getColor").SetResult("blue");
+		JSInterop.Setup<string>("themeManager.getBrightness")
+				.SetException(new InvalidOperationException("unexpected failure"));
+
+		// Act
+		var act = () => Render<ThemeProvider>();
+
+		// Assert
+		act.Should().Throw<InvalidOperationException>().WithMessage("unexpected failure");


Same issue as above: ThemeProvider currently swallows all exceptions during getBrightness initialization, so this test expecting InvalidOperationException to propagate will fail unless the component is changed to only suppress JSException.

 		adminBadge.Should().NotBeNull("Admin role should render with red-100 background");
-		adminBadge!.GetAttribute("class").Should().Contain("text-red-800");
+		adminBadge.GetAttribute("class").Should().Contain("text-red-800");


adminBadge is nullable (FirstOrDefault), and the NotBeNull() assertion doesn't inform the compiler. This introduces nullable dereference warnings on the next line. Consider using the null-forgiving operator (or extracting a non-null reference after the assertion) before calling GetAttribute.

 		authorBadge.Should().NotBeNull("Non-admin role should render with green-100 background");
-		authorBadge!.GetAttribute("class").Should().Contain("text-green-800");
+		authorBadge.GetAttribute("class").Should().Contain("text-green-800");


authorBadge is nullable (FirstOrDefault), and NotBeNull() doesn't affect nullability flow analysis. This will produce nullable dereference warnings on the following GetAttribute call unless you null-forgive or capture a non-null reference after the assertion.

Suggested change

authorBadge.GetAttribute("class").Should().Contain("text-green-800");

var authorBadgeElement = authorBadge!;

authorBadgeElement.GetAttribute("class").Should().Contain("text-green-800");
