Question

我很难解决这个问题。任何帮助是极大的赞赏。我的restClient.Object获取一个null异常。当我检查restClient的.Object时，我得到了

消息：调用目标已抛出异常。

内部异常：值不能为null。参数名称：source

是的，我指的是这行代码：

var client = new IncidentRestClient(**restClient.Object**);

我是否错误地嘲笑对象？

[Test]
public void Insert_Method_Throws_exception_if_response_StatusCode_is_not_Created()
{
    //Arrange
    var restClient = new Mock<RestClient>();
    restClient.Setup(x => x.Execute<RootObject>(It.IsAny<IRestRequest>()))
        .Returns(new RestResponse<RootObject>
        {
            StatusCode = HttpStatusCode.BadRequest 
        });

    var client = new IncidentRestClient(restClient.Object);

    Assert.Throws<Exception>(() => client.CreateNewIncident(insertIncidentRequest));
}

Answer 1

卸载并重新安装Moq对我不起作用。相反，将Mock对象上的CallBase属性设置为true可以解决问题：

var restClientMock = new Mock<RestClient> { CallBase = true };

Answer 2

问题已经解决。我不得不卸载并重新安装Moq与nuget。
