无法解析类型名称。请检查配置文件

Question

尝试使用moq和unity对我的应用程序进行单元测试时，我遇到了错误，因为我的服务是一个接口，无法解决：

错误消息：

    Test method Ecommerce_Test.Tests.LoginSuccessfulRedirectToActionLoad threw exception: 
System.InvalidOperationException: The type name or alias Ecommerce_Test.AuthenticationMock could not be resolved. Please check your configuration file and verify this type name.

配置文件：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration"/>
  </configSections>
  <unity xmlns="http://schemas.microsoft.com/practices/2010/unity">

    <assembly  name="Ecommerce"/>
    <assembly  name="Ecommerce_Tests"/>

    <container>
      <register type="Ecommerce.Authentication.IAuthentication"
                mapTo="Ecommerce_Test.AuthenticationMock, Ecommerce_Test" />
    </container>
  </unity>
  <system.serviceModel>
      <bindings />
      <client />
  </system.serviceModel>
</configuration>

用法：

public ActionResult Login(HomeModels.LoginModel model)
        {
            var unity = new UnityContainer().LoadConfiguration(); //error fired here!!!
            var proxy = unity.Resolve<IAuthentication>();


            if (ModelState.IsValid)
            {
                try
                {
                    Login log = new Login();
                    log.Username = model.Username;
                    log.Password = model.Password;
                    int result = proxy.Login(new Login { Username = log.Username, Password = log.Password });

                }
                catch (MemberAccessException e)
                {
                    ModelState.AddModelError("Login was not successful", e);
                }
            }
            return View("Login",model);
        }

Answer 1

结果，解决方案是将程序集的名称附加到mapTo值的末尾。上面的配置文件进行了更新以反映这一点。

通过右键单击Ecommerce_Tests project > Properties找到的程序集名称。

此外，如果对注入的代码使用单独的dll，请确保目标框架相同，并且将包含注入类的dll复制到run (debug)文件夹中
