Microsoft.AspNetCore.Mvc.Testing 10.0.0-preview.3.25172.1

About

Microsoft.AspNetCore.Mvc.Testing provides support for writing integration tests for ASP.NET Core apps that utilize MVC or Minimal APIs.

Key Features

• Copies the dependencies file (.deps.json) from the System Under Test (SUT) into the test project's bin directory
• Sets the content root to the SUT's project root so that static files are found during test execution
• Provides the WebApplicationFactory class to streamline bootstrapping the SUT with TestServer

How to Use

To use Microsoft.AspNetCore.Mvc.Testing, follow these steps:

Installation

To install the package, run the following command from the directory containing the test project file:

dotnet add package Microsoft.AspNetCore.Mvc.Testing

Configuration

To configure the test app, follow these steps:

1. Specify the Web SDK in the test project file (<Project Sdk="Microsoft.NET.Sdk.Web">).
2. Add references to the following packages:
   • xunit
   • xunit.runner.visualstudio
   • Microsoft.NET.Test.Sdk
3. Add a test class to the test project:

   public class BasicTests
       : IClassFixture<WebApplicationFactory<Program>>
   {
       private readonly WebApplicationFactory<Program> _factory;
   
       public BasicTests(WebApplicationFactory<Program> factory)
       {
           _factory = factory;
       }
   
       [Theory]
       [InlineData("/")]
       [InlineData("/Index")]
       [InlineData("/About")]
       [InlineData("/Privacy")]
       [InlineData("/Contact")]
       public async Task Get_EndpointsReturnSuccessAndCorrectContentType(string url)
       {
           // Arrange
           var client = _factory.CreateClient();
   
           // Act
           var response = await client.GetAsync(url);
   
           // Assert
           response.EnsureSuccessStatusCode(); // Status Code 200-299
           Assert.Equal("text/html; charset=utf-8",
               response.Content.Headers.ContentType.ToString());
       }
   }
