moq 4.5.29 - 出现错误“'Moq.Proxy.CastleProxyFactory' 的类型初始值设定项抛出异常。”

Question

我正在使用 xUnit 2.x 和最小起订量 4.5 以及 castle.core 3.3.0.0。我在与我的单元测试不同的程序集（但属于同一解决方案的一部分）中有 IAssessmentsRepository 接口。我正在引用 IAssessmentsRepository 所在的程序集。但是当我尝试模拟时，它会出现 "Type initilization" 错误，这意味着最小起订量无法加载类型，即 IAssessmentsRepository 。现在我不明白为什么？如果有人遇到同样的问题，请提出建议。

  [Fact]
            [UnitTest]
            public void DeleteAssessment_ShouldCall_AssessmentsRepository_DeleteAssessment_Method()
            {
                //Arrange
                var assessmentRepoMock = new Mock<Data.Assessments.IAssessmentsRepository>();
                assessmentRepoMock.Setup(x => x.DeleteAssessment(It.IsAny<int>(), It.IsAny<string>())).Returns(true);

                var assessmentService = new AssessmentService(assessmentRepoMock.Object);

                //Act
                var testResult = assessmentService.DeleteAssessment(It.IsAny<int>(), It.IsAny<string>());

                //Assert

                assessmentRepoMock.Verify(r => r.DeleteAssessment(It.IsAny<int>(), It.IsAny<string>()), Times.Once);

            }

以下是错误的堆栈跟踪，

Answer 1

我找到了问题的根本原因，这有点奇怪。它与我在测试项目中的 app.config 文件有关。当我遇到这个问题时，我的 app.config 如下所示：

<configuration>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
                <bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
    <configSections>
    </configSections>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>
</configuration>

我需要做的就是确保 configSections 标记是我的根元素的第一个子元素，所以我更新了我的 app.config 文件如下：

<configuration>
    <configSections>
    </configSections>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
                <bindingRedirect oldVersion="0.0.0.0-9.0.0.0" newVersion="9.0.0.0" />
            </dependentAssembly>
        </assemblyBinding>
    </runtime>

    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>
</configuration>

瞧，问题解决了。错误信息太混乱了。
