teamcity - 如何从 Cake 获取 TeamCity 中的 DotCover 覆盖率

Question

我最近采用了构建工具 Cake ，但我正在努力让 DotCover 单元测试覆盖率报告显示在 TeamCity 中。

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);
});

然而，这会从 TeamCity 产生以下输出:

似乎 TeamCity 正在尝试合并 dotcover 快照，但我认为我没有告诉它这样做。我还发现在部署到 Octopus 任务开始后上传 artifacts/results.dcvr 很奇怪

我已经尝试使用 DotCoverAnalyze 和“result.xml”的 resultPath，但 TeamCity 报告它是一种无效的文件格式。

那么，您如何使用 cake 和 TeamCity 收集和导入 DotCover 覆盖范围？

Answer 1

这就是我目前将 dotCover 覆盖率报告导入 TeamCity 的方式。请注意我如何提供 DotCover.exe 主目录的绝对路径以覆盖捆绑的 DotCover.exe。当捆绑的 DotCover 版本与您在 Cake 中使用的版本(例如，在您的 .\tools 文件夹中找到的版本)不兼容时，这可能很有用。

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
            });
    }
});
