RestSharp Moq 对象空异常 C# REST 单元测试

Question

我在尝试解决这个问题时遇到了困难。任何帮助是极大的赞赏。我的 restClient.Object 得到一个空异常。当我检查 restClient 的 .Object 时，我得到

消息：调用目标抛出异常。

内部异常：值不能是null.Parameter名称：来源

顺便说一句，我指的是这行代码：

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

我是否错误地模拟了对象？

[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

问题已解决。我不得不用 nuget 卸载并重新安装 Moq。

Answer 2

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 就可以了：

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