如何从Cake获得TeamCity的DotCover覆盖率

我最近采用了构建工具，但我很难在TeamCity中显示DotCover单元测试覆盖率报告

我尝试了以下任务：

Task("Run-Regression-Tests")
    .IsDependentOn("Build")
    .Does(() =>
{
    var resultPath = artifactsDirectory + File("results.dcvr");
    DotCoverCover(tool => 
        {
            tool.NUnit3(new[] {
                "./Foo.UnitTests/bin/" + configuration + "/Foo.UnitTests.dll",
                "./Bar.UnitTests/bin/" + configuration + "/Bar.UnitTests.dll",
                "./Baz.IntegrationTests/bin/" + configuration + "/Baz.IntegrationTests.dll"
            }, new NUnit3Settings {
                NoResults = true
            });
        },
        resultPath,
        new DotCoverCoverSettings()
            .WithFilter("+:Foo.Domain"));

    TeamCity.ImportDotCoverCoverage(resultPath);
});

但是，这将从TeamCity生成以下输出：

// Output immediately after unit test success report:

TeamCity似乎正在尝试合并dotcover快照，但我想我没有告诉它。我还发现奇怪的是，artifacts/results.dcvr是在deploy to octopus任务启动后上传的

我尝试使用DotCovernanalyze，结果路径为“result.xml”，但TeamCity报告这是一种无效的文件格式

那么，如何使用cake和TeamCity收集和导入DotCover覆盖率？

这是我当前如何将DotCover覆盖率报告导入TeamCity的。请注意，我是如何给出DotCover.exe主目录的绝对路径以覆盖捆绑的DotCover.exe的。当捆绑的DotCover版本与您与Cake一起使用的DotCover版本（例如

\tools

文件夹中的版本）之间可能存在不兼容时，这可能非常有用

Task("Run-Unit-Tests")
    .IsDependentOn("Build")
    .Does(() =>
{
    DotCoverCover((ICakeContext c) => {
            c.NUnit3("./src/**/bin/x64/" + parameters.Configuration + "/Foo.Test.dll",
                new NUnit3Settings
                {
                    Results = parameters.Paths.TestResult,
                    TeamCity = parameters.IsTeamCity
                }
            );
        },
        parameters.Paths.CoverageResult,
        new DotCoverCoverSettings()
            .WithFilter("+:Foo")
            .WithFilter("-:Foo.Test"));
})
.Finally(() =>
{
    if(parameters.IsTeamCity)
    {
        TeamCity.ImportData("nunit", parameters.Paths.TestResult);
        TeamCity.ImportDotCoverCoverage(
            parameters.Paths.CoverageResult,
            MakeAbsolute(Directory("./tools/JetBrains.dotCover.CommandLineTools/tools")));
    }
    else
    {
        DotCoverReport(
            parameters.Paths.CoverageResult,
            parameters.Paths.CoverageResult.ChangeExtension("html"),
            new DotCoverReportSettings
            {
                ReportType = DotCoverReportType.HTML
            });
    }
});

您可以通过使用Cake的内置工具定位器获取dotcover.exe的路径来增强上述代码。然后代码看起来像

MakeAbsolute（Context.Tools.Resolve（“dotcover.exe”）.GetDirectory（）
