+# Support for render modes and `RendererInfo`
+This article explains how to emulate different render modes and `RendererInfo` in bUnit tests.
+
+Render modes in Blazor Web Apps determine the hosting model and interactivity of components. A render mode can be applied to a component using the `@rendermode` directive. The [`RendererInfo`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.components.rendererinfo?view=aspnetcore-9.0) allows the application to determine the interactivity and location of the component. For more details, see the [Blazor render modes](https://learn.microsoft.com/en-us/aspnet/core/blazor/components/render-modes?view=aspnetcore-9.0) documentation.
+
+## Setting the render mode for a component under test
+Setting the render mode can be done via the <xref:Bunit.ComponentParameterCollectionBuilder`1.SetAssignedRenderMode(Microsoft.AspNetCore.Components.IComponentRenderMode)> method when writing in a C# file. In a razor file use the `@rendermode` directive. Both take an [`IComponentRenderMode`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.components.icomponentrendermode?view=aspnetcore-9.0) object as a parameter. Normally this is one of the following types:
+ * [`InteractiveAutoRenderMode`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.components.web.interactiveautorendermode?view=aspnetcore-9.0)
+ * [`InteractiveServerRendeMode`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.components.web.interactiveserverrendermode?view=aspnetcore-9.0)
+ * [`InteractiveWebAssemblyRenderMode`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.components.web.interactivewebassemblyrendermode?view=aspnetcore-9.0)
+
+For ease of use the [`RenderMode`](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.components.web.rendermode?view=aspnetcore-9.0) class defines all three of them.
+
+For example `MovieComponent.razor`:
+```razor
+@if (AssignedRenderMode is null)
+{
+    // The render mode is Static Server
+    <form action="/movies">
+        <input type="text" name="titleFilter" />
+        <input type="submit" value="Search" />
+    </form>
+}
+else
+{
+    // The render mode is Interactive Server, WebAssembly, or Auto
+    <input @bind="titleFilter" />
+    <button @onclick="FilterMovies">Search</button>
+}
+```
+
+The following example shows how to test the above component to check both render modes:
+
+# [C# test code](#tab/csharp)
+
+```csharp
+[Fact]
+public void InteractiveServer()
+{
+  // Act
+  var cut = RenderComponent<MovieComponent>(ps => ps
+    .SetAssignedRenderMode(RenderMode.InteractiveServer));
+
+  // Assert
+  cut.MarkupMatches("""
+                    <input diff:ignoreAttributes />
+                    <button>Search</button>
+                    """);
+}
+
+[Fact]
+public void StaticRendering()
+{
+  // Act
+  var cut = RenderComponent<MovieComponent>();
+  // This is the same behavior as:
+  // var cut = RenderComponent<MovieComponent>(ps => ps
+  //  .SetAssignedRenderMode(null));
+
+  // Assert
+  cut.MarkupMatches("""
+                    <form action="/movies">
+                    <input type="text" name="titleFilter" />
+                    <input type="submit" value="Search" />
+                    </form>
+                    """);
+}
+```
+
+# [Razor test code](#tab/razor)
+
+```razor
+@inherits TestContext
+@code {
+  [Fact]
+  public void InteractiveServer()
+  {
+    // Act
+    var cut = Render(@<MovieComponent @rendermode="RenderMode.InteractiveServer" />);
+
+    // Assert
+    cut.MarkupMatches(@<text>
+                        <input diff:ignoreAttributes />
+                        <button>Search</button>
+                       </text>);
+  }
+
+  [Fact]
+  public void StaticRendering()
+  {
+    // Act
+    var cut = Render(@<MovieComponent />);
+
+    // Assert
+    cut.MarkupMatches(@<form action="/movies">
+                          <input type="text" name="titleFilter" />
+                          <input type="submit" value="Search" />
+                        </form>);
+  }
+}
+```
+
+***
+
+## Setting the `RendererInfo` during testing
+To control the `ComponentBase.RendererInfo` property during testing, use the <xref:Bunit.TestContextBase.SetRendererInfo(Microsoft.AspNetCore.Components.RendererInfo)> method on the `TestContext` class. The `SetRendererInfo` method takes an nullable `RendererInfo` object as a parameter. Passing `null` will set the `ComponentBase.RendererInfo` to `null`. 
+
+A component (`AssistentComponent.razor`) might check if interactivity is given to enable a button:
+
+```razor
+@if (RendererInfo.IsInteractive)
+{
+    <p>Hey I am your assistant</p>
+}
+else
+{
+    <p>Loading...</p>
+}
+```
+
+In the test, you can set the `RendererInfo` to enable or disable the button:
+
+```csharp
+[Fact]
+public void SimulatingPreRenderingOnBlazorServer()
+{
+  // Arrange
+  SetRendererInfo(new RendererInfo(rendererName: "Static", isInteractive: false));
+
+  // Act
+  var cut = RenderComponent<AssistentComponent>();
+
+  // Assert
+  cut.MarkupMatches("<p>Loading...</p>");
+}
+
+[Fact]
+public void SimulatingInteractiveServerRendering()
+{
+  // Arrange
+  SetRendererInfo(new RendererInfo(rendererMode: "Server", isInteractive: true));
+
+  // Act
+  var cut = RenderComponent<AssistentComponent>();
+
+  // Assert
+  cut.MarkupMatches("<p>Hey I am your assistant</p>");
+}
+```
+
+> [!NOTE]
+> If a component under test uses the `ComponentBase.RendererInfo` property and the `SetRendererInfo` on `TestContext` hasn't been passed in a `RendererInfo` object, the renderer will throw an exception.
