Unit testing 在单元测试用例中重置模拟数据

我正在使用Rhino Mock，希望根据单元测试中传递的参数设置不同的数据。当我单独运行它们时，它们按预期运行，但是当我并行运行它们时，数据集一次不会改变，尽管if-else代码会执行

public SetMockData(bool pass=true)
    {
       var jsonDataPass = "{\"results\":[{\"a\":\"12345\",\"StatusId\":\"12\",\"Id\":\"30\",\"PrimaryId\":\"1\"}";
       var jsonDataFails = "{\"results\":[{\"a\":\"12875\",\"StatusId\":\"13\",\"Id\":\"34\",\"PrimaryId\":\"2\"}";

      var apiClient = MockRepository.GenerateMock<IApiClient>();
      apiClient.Stub(x => x.GetApiUrl(null, null)).IgnoreArguments().Return("");
      if (pass)
      {
        apiClient.Stub(x => x.ExecuteAsync<JToken>(Arg<string>.Is.Anything, Arg<HttpMethod>.Is.Anything, Arg<StringContent>.Is.Anything)).IgnoreArguments().Return(Task.FromResult(new ServiceResponse<JToken>
        {
          Data = JObject.Parse(jsonDataPass),
          Outcome = Success
        }));
        apiClient.Stub(x => x.ExecuteAsync<JToken>(Arg<string>.Is.Anything, Arg<string>.Is.Anything, Arg<HttpMethod>.Is.Anything, Arg<StringContent>.Is.Anything)).IgnoreArguments().Return(Task.FromResult(new ServiceResponse<JToken>
        {
          Data = JObject.Parse(jsonDataPass),
          Outcome = Success
        }));
      }
      else
      {
        apiClient.Stub(x => x.ExecuteAsync<JToken>(Arg<string>.Is.Anything, Arg<HttpMethod>.Is.Anything, Arg<StringContent>.Is.Anything)).IgnoreArguments().Return(Task.FromResult(new ServiceResponse<JToken>
        {
          Data = JObject.Parse(jsonDataFails),
          Outcome = Success
        }));
        apiClient.Stub(x => x.ExecuteAsync<JToken>(Arg<string>.Is.Anything, Arg<string>.Is.Anything, Arg<HttpMethod>.Is.Anything, Arg<StringContent>.Is.Anything)).IgnoreArguments().Return(Task.FromResult(new ServiceResponse<JToken>
        {
          Data = JObject.Parse(jsonDataFails),
          Outcome = Success
        }));
      }
      IoCFactory.RegisterInstance(typeof(IApiClient), apiClient); 
    }

public SetMockData（bool pass=true）
{
var jsonDataPass=“{\'结果\”：[{\'a\'：\'12345\，\'StatusId\'：\'12\，\'Id\'：\'30\，\'PrimaryId\'：'1\'；
var jsonDataFails=“{\'results\”：[{\'a\'：\'12875\，\'StatusId\'：\'13\，\'Id\'：\'34\，\'PrimaryId\'：'2\'；
var apiClient=MockRepository.GenerateMock（）；
apiClient.Stub（x=>x.GetApiUrl（null，null））.IgnoreArguments（）.Return（“”）；
如果（通过）
{
apiClient.Stub（x=>x.ExecuteAsync（Arg.Is.Anything，Arg.Is.Anything，Arg.Is.Anything））.IgnoreArguments（）.Return（Task.FromResult（new ServiceResponse
{
Data=JObject.Parse（jsonDataPass），
结果=成功
}));
apiClient.Stub（x=>x.ExecuteAsync（Arg.Is.Anything，Arg.Is.Anything，Arg.Is.Anything，Arg.Is.Anything，Arg.Is.Anything））.IgnoreArguments（）.Return（Task.FromResult（new ServiceResponse
{
Data=JObject.Parse（jsonDataPass），
结果=成功
}));
}
其他的
{
apiClient.Stub（x=>x.ExecuteAsync（Arg.Is.Anything，Arg.Is.Anything，Arg.Is.Anything））.IgnoreArguments（）.Return（Task.FromResult（new ServiceResponse
{
Data=JObject.Parse（jsonDataFails），
结果=成功
}));
apiClient.Stub（x=>x.ExecuteAsync（Arg.Is.Anything，Arg.Is.Anything，Arg.Is.Anything，Arg.Is.Anything，Arg.Is.Anything））.IgnoreArguments（）.Return（Task.FromResult（new ServiceResponse
{
Data=JObject.Parse（jsonDataFails），
结果=成功
}));
}
IoCFactory.RegisterInstance（类型为（IapClient），ApicClient）；
}

为什么要让模拟数据设置并行运行？这会带来各种各样的问题
