About

Microsoft.AspNetCore.TestHost provides an ASP.NET Core web server for testing middleware in isolation.

Key Features

  • Instantiate an app pipeline containing only the components that you need to test
  • Send custom requests to verify middleware behavior

How to Use

To use Microsoft.AspNetCore.TestHost, follow these steps:

Installation

dotnet add package Microsoft.AspNetCore.TestHost

Usage

To set up the TestServer, configure it in your test project. Here's an example:

[Fact]
public async Task MiddlewareTest_ReturnsNotFoundForRequest()
{
    // Build and start a host that uses TestServer
    using var host = await new HostBuilder()
        .ConfigureWebHost(builder =>
        {
            builder.UseTestServer()
                .ConfigureServices(services =>
                {
                    // Add any required services that the middleware uses
                    services.AddMyServices();
                })
                .Configure(app =>
                {
                    // Configure the processing pipeline to use the middleware
                    // for the test
                    app.UseMiddleware<MyMiddleware>();
                });
        })
        .StartAsync();

    var response = await host.GetTestClient().GetAsync("/");

    Assert.Equal(HttpStatusCode.NotFound, response.StatusCode);
}

Main Types

The main types provided by this package are:

  • TestServer: An IServer implementation for executing tests
  • TestServerOptions: Provides options for configuring a TestServer
