This is a sample benchmark.net test app that can be used to measure Blazor components.

Read the documentation for benchmark.net to learn how to use it.

The BenchmarkRenderer

A minimal Blazor renderer is included in the form of the BenchmarkRenderer, that just allows rendering of a component one or more times, with or without a ParameterView passed in. It does not produce any markup or output.

Usage:

To create an instance of the BenchmarkRenderer, do the following:

var renderer = new BenchmarkRenderer();

To enable services to be injected into the component being measured, do the following:

var services = new ServiceCollection();

// Add services to inject into components
// rendered with the renderer here, e.g.:
services.AddSingleton<IFoo, Foo>();

var renderer = new BenchmarkRenderer();

To render a component (any type that implements IComponent), do the following:

// Render without parameters passed to Component1
var component = await renderer.RenderAsync<Component1>(ParameterView.Empty);

// Render with parameters passed to Component1
component = await renderer.RenderAsync<Component1>(ParameterView.FromDictionary(new Dictionary<string, object?>()
{
    { "Text", "Foo" }
}));

To re-render and optionally pass new parameters to a component, do the following:

// Set new parameters and re-render
await renderer.SetParametersAsync(component, ParameterView.FromDictionary(new Dictionary<string, object?>()
{
    { "Text", "Foo" }
}));

// Re render without setting new parameters
await renderer.SetParametersAsync(component, ParameterView.Empty);

Tips:

• Get the number of render cycles performed by the BenchmarkRenderer through BenchmarkRenderer.RenderCount property.
• Get any unhandled exception thrown during rendering via the BenchmarkRenderer.UnhandledException property. This is reset at the beginning of calls to BenchmarkRenderer.Render() and BenchmarkRenderer.SetParametersAsync().
