在测试项目中安装以下NuGet包：

• bunit
• Microsoft.AspNetCore.Components.WebAssembly.Testing
• Microsoft.AspNetCore.Components.Testing

引用以下命名空间：

• Bunit
• Microsoft.AspNetCore.Components.WebAssembly.Testing
• Microsoft.AspNetCore.Components.Testing

创建测试类并使用Bunit的测试工具和AntBlazor组件进行初始化：

using Bunit;
using Microsoft.AspNetCore.Components.Testing;
using Microsoft.Extensions.DependencyInjection;
using Xunit;

namespace MyProject.Tests
{
    public class MyComponentTests : TestContext
    {
        public MyComponentTests()
        {
            Services.AddScoped();

            // You can add other services that your component needs here.

            // Set up AntBlazor's configuration.
            Services.AddAntBlazor();

            // Add your component to the test context.
            // Note: AntBlazor's CSS is not loaded by default in bUnit, so we set it up here.
            // For more information, see https://ant.design/docs/react/use-with-create-react-app#Change-default-Theme.
            var cssFilePath = Env.ContentRootPath + "../../node_modules/antd/dist/antd.css";
            Services.ConfigureCss(cssFilePath);

            // Add the required JavaScript files for AntBlazor's features.
            var jsFilePaths = new[]
            {
                Env.ContentRootPath + "../../node_modules/moment/moment.js",
                Env.ContentRootPath + "../../node_modules/antd/dist/antd.js",
                Env.ContentRootPath + "../../node_modules/@ant-design/icons/dist/anticons.min.js"
            };
            Services.ConfigureJs(jsFilePaths);
            
            // Use the test renderer for AntBlazor.
            Renderer = Services.GetService();
        }
        
        [Fact]
        public void MyTest()
        {
            // Arrange
            var myComponent = Renderer.RenderComponent();

            // Act
            // Do stuff with your component.

            // Assert
            // Assert something about your component's output.
        }
    }
}

运行测试即可。
