当测试运行器中的测试失败时,如何使OpenCover返回错误？

Question

使用以下Cake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的调用也不会因预期的异常而失败.

有没有办法告诉OpenCover失败,如果实际上有单元测试失败？

该OpenCoverSettings类包含ReturnTargetCodeOffset财产.通过将此值设置为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.你可以在这里找到更多相关信息.有了这个,Cake会在出现测试失败时正确处理非零退出代码,并因测试失败而抛出异常.

上面的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));
});
