c# – 错误单元测试webapi控制器

我正在使用AspNet Web Api Client 5.0,我正在尝试单元测试一个web api控制器.

var encservice = new EncryptionService();
var acctservice = FakeServices.GetAccountService();
var controller = new AccountController(acctservice,encservice);
controller.Request = new HttpRequestMessage();

当代码

controller.Request.SetConfiguration(new HttpConfiguration());

被执行我遇到异常

Message: Could not load file or assembly ‘Newtonsoft.Json,Version=4.5.0.0,Culture=neutral,PublicKeyToken=30ad4fe6b2a6aeed’ or one of its dependencies. The located assembly’s manifest deFinition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Source: System.Net.Http.Formatting

我使用的newsoft.json的版本是6.0

我的配置文件中也有一个程序集重定向

<dependentAssembly>
    <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
  </dependentAssembly>

使用的测试跑步者是MStest,VS2012

解决方法

您需要添加一个 assembly redirect：

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json"
                          publicKeyToken="30ad4fe6b2a6aeed"
                          culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

(假设Newtonsoft.Json的装配版本正好是6.0.0.0)
