ASP.NET Core 中做集成测试的三种方案

 Mock<IBlogArticleServices> mockBlogSev = new Mock<IBlogArticleServices>(); Mock<ILogger<BlogController>> mockLogger = new Mock<ILogger<BlogController>>(); BlogController blogController;

     var container = dI_Test.DICollections();     blogArticleServices = container.Resolve<IBlogArticleServices>();     blogController = new BlogController(mockLogger.Object); }

  using (var server = CreateServer())  {      var response = await server.CreateClient()          .GetAsync(Get.ItemById(1));

 public IServiceProvider ConfigureServices(IServiceCollection servic {     // 自定义服务扩展     services.AddAppInsight(Configuration)         // and so on...         .AddCustomMVC(Configuration);
