C# 当测试运行程序中的测试失败时，如何使OpenCover返回错误？

使用以下脚本时：

Task("Test-xUnit")
    .WithCriteria(() => DirectoryExists(parameters.Paths.Directories.PublishedxUnitTests))
    .Does(() =>
{
    EnsureDirectoryExists(parameters.Paths.Directories.xUnitTestResults);

    OpenCover(tool => {
        tool.XUnit2(GetFiles(parameters.Paths.Directories.PublishedxUnitTests + "/**/*.Tests.dll"), new XUnit2Settings {
            OutputDirectory = parameters.Paths.Directories.xUnitTestResults,
            XmlReport = true,
            NoAppDomain = true
        });
    },
    parameters.Paths.Files.TestCoverageOutputFilePath,
    new OpenCoverSettings()
        .WithFilter(testCoverageFilter)
        .ExcludeByAttribute(testCoverageExcludeByAttribute)
        .ExcludeByFile(testCoverageExcludeByFile));
});

即使存在一些失败的测试，对OpenCover的调用也不会像预期的那样出现异常

如果单元测试确实失败了，是否有方法告诉OpenCover失败？

该类包含该属性。通过将其设置为0，您告诉OpenCover返回目标进程的返回代码，而不是它自己的返回代码。你可以找到更多关于这方面的信息。这样，当测试失败时，Cake将正确处理非零退出代码，并由于测试失败而引发异常

上述代码段应更改为以下内容：

Task("Test-xUnit")
    .WithCriteria(() => DirectoryExists(parameters.Paths.Directories.PublishedxUnitTests))
    .Does(() =>
{
    EnsureDirectoryExists(parameters.Paths.Directories.xUnitTestResults);

    OpenCover(tool => {
        tool.XUnit2(GetFiles(parameters.Paths.Directories.PublishedxUnitTests + "/**/*.Tests.dll"), new XUnit2Settings {
            OutputDirectory = parameters.Paths.Directories.xUnitTestResults,
            XmlReport = true,
            NoAppDomain = true
        });
    },
    parameters.Paths.Files.TestCoverageOutputFilePath,
    new OpenCoverSettings { ReturnTargetCodeOffset = 0 }
        .WithFilter(testCoverageFilter)
        .ExcludeByAttribute(testCoverageExcludeByAttribute)
        .ExcludeByFile(testCoverageExcludeByFile));
});
