Jenkins失败的NUnit测试(nunit xml结果文件为空)

Question

最近，我开始在Jenkins构建服务器上构建我的C#项目。

但是最近我遇到了一个问题，即报告的NUnit xml是空的(文件是创建的，但没有内容)。

控制台输出如下

进程泄漏的文件描述符。有关更多信息，请参见http://wiki.jenkins-ci.org/display/JENKINS/Spawning+processes+from+build以解析控制台日志中的警告，解析器MSBuild警告计算基于参考构建#288记录NUnit测试结果错误:由于异常而中止的步骤“发布NUnit测试结果报告”：hudson.util.IOException2:无法转换NUnit报告。请将此问题报告给hudson.plugins.nunit.NUnitArchiver.invoke(NUnitArchiver.java:65) at hudson.plugins.nunit.NUnitArchiver.invoke(NUnitArchiver.java:26) at hudson.FilePath.act(FilePath.java:990) at hudson.FilePath.act(FilePath.java:968) at hudson.plugins.nunit.NUnitPublisher.perform(NUnitPublisher.java:145) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:20) at hudson.model.AbstractBuild$AbstractBuildExecution.perform(AbstractBuild.java:782) at hudson.model.AbstractBuild$AbstractBuildExecution.performAllBuildSteps(AbstractBuild.java:723) at hudson.model.Build$BuildExecution.post2(Build.java:185) at hudson.model.AbstractBuild$AbstractBuildExecution.post(AbstractBuild.java:668

我知道问题可能是泄露的文件描述符，但我不太确定如何解决这个问题。

NUnit测试使用powershell脚本执行，该脚本获取所有必需的dll。

powershell脚本：

param(
[string] $sourceDirectory = "./trunk/TestProjects/"
, $fileFilters = @("*UnitTest*.dll")
, [string]$filterText = "*\bin*"
)

#script that executes all unit tests available.


Write-Host "Source: $sourceDirectory"
Write-Host "File Filters: $fileFilters"
Write-Host "Filter Text: $filterText"

$cFiles = ""
$nUnitExecutable = "C:\Program Files (x86)\NUnit.org\nunit-console\nunit3-console.exe"

# look through all subdirectories of the source folder and get any unit test assemblies. To avoid duplicates, only use the assemblies in the bin folder
[array]$files = get-childitem $sourceDirectory -include $fileFilters -recurse | select -expand FullName | where {$_ -like $filterText}

foreach ($file in $files)
{
    $cFiles = $cFiles + '"' + $file + '"' + " "
}

# set all arguments and execute the unit console
$argumentList = @("$cFiles", "--result=nunit-result.xml;format=nunit2","--framework=net-4.5","--process=Single")

$unitTestProcess = start-process -filepath $nUnitExecutable -argumentlist $argumentList -nonewwindow
echo "$nUnitExecutable $argumentList"


$exitCode = $unitTestProcess.ExitCode

exit $exitCode

此问题仅在脚本通过jenkins执行时才会发生。

#######################UPDATE

经过一些调查后，我发现他只会在我添加一个测试用例时发生，其中wpf控件是通过在UI线程上调用wpf控件来创建的。

        [Test Apartment(ApartmentState.STA) RunInApplicationDomain]
    public void CheckPluginModel()
    {
        var app = Application.Current ?? new Application { ShutdownMode = ShutdownMode.OnExplicitShutdown };
        PluginModel model = new PluginModel();

        var task= model.LoadPluginsFromPath(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location));


        RunApplication(() => task.IsCompleted);


        Assert.That(model.AvailablePluginControls.Count, Is.EqualTo(1));
        Assert.That(model.Workflows.Count, Is.EqualTo(1));
        Console.WriteLine("Plugin model check finished");

    }

RunApplication：

        /// <summary>
    /// Runs the application. as long as abortCriteria returns false
    /// </summary>
    /// <param name="abortCriteria">The abort criteria.</param>
    private void RunApplication(Func<bool> abortCriteria, int duetime = 100, int period=100)
    {

        Console.WriteLine("Application started");
        System.Threading.Timer timer = null;
        timer = new Timer((obj) =>
        {
            if (abortCriteria.Invoke())
            {
                Application.Current.Dispatcher.Invoke(() => Application.Current.Shutdown());
                timer.Dispose();

            }
        }, null, duetime, period); 

        Application.Current.Run();

        Console.WriteLine("Application stopped");
    }

创建所有GUI元素

await Application.Current.Dispatcher.BeginInvoke(new Action(() => AvailablePluginControls.Add((APControl)Activator.CreateInstance(item))),null);

Answer 1

问题如下：

单元测试通过powershell脚本执行。powershell启动进程不会等到进程完成。这会导致子进程未完成的问题。

为了让启动进程等到进程完成，必须添加标志-Wait。

Answer 2

Jenkins中的Nunit插件不支持Nunit 3 xml格式。我在詹金斯身上也有类似的问题。我曾将Nunit 3结果格式转换为Nunit 2格式。

"C:\NUnit 3.5.0\nunit3-console.exe" /result:\MyApplication.xml;format=nunit2 "D:\Jenkins\workspace\MyApplication.Tests.dll"
