这需要进行集成测试内存中的测试服务器，因为该属性在处理请求管道时由框架评估。

This would need integration testing with an in-memory test server because the attribute is evaluated by the framework as it processes the request pipeline.

ASP.NET Core中的集成测试

集成测试可确保将应用程序的组件组装在一起时可以正常运行。 ASP.NET Core支持使用单元测试框架和内置的测试Web主机进行集成测试，该主机可以用于处理请求而无需网络开销。

Integration testing ensures that an application's components function correctly when assembled together. ASP.NET Core supports integration testing using unit test frameworks and a built-in test web host that can be used to handle requests without network overhead.

[Fact]
public async Task GetAsync_InvalidScope_ReturnsUnauthorizedResult() {
    // Arrange
    var server = new TestServer(new WebHostBuilder().UseStartup<Startup>());
    var client = server.CreateClient();
    var url = "api/foo";
    var expected = HttpStatusCode.Unauthorized;

    // Act
    var response = await client.GetAsync(url);

    // Assert
    Assert.AreEqual(expected, response.StatusCode);
}

您还可以创建一个专门用于测试的启动，它将替换所有依赖项如果您不希望测试打到实际的生产实现中，则可以使用存根/模拟的DI来实现。

You can also create a start up specifically for the test that will replace any dependencies for DI with stubs/mocks if you do not want the test hitting actual production implementations.
