unit-testing - Howto resolve .net test hangs on "Starting test execution, please wait..."

问题描述

I am trying to execute dotnet test from the command line on our Jenkins build server, but it just hangs on:

Starting test execution, please wait...

It works fine when running this command locally

If I switch to using dotnet xunit it fails with the following:

15:42:57 Locating binaries for framework netcoreapp2.1...
15:42:58 Running .NET Core 2.1 tests for framework netcoreapp2.1...
15:42:58 The specified framework version '2.1' could not be parsed
15:42:58 The specified framework 'Microsoft.NETCore.App', version '2.1' was not found.
15:42:58   - Check application dependencies and target a framework version installed at:
15:42:58       C:\Program Files\dotnet\
15:42:58   - Installing .NET Core prerequisites might help resolve this problem:
15:42:58       http://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
15:42:58   - The .NET Core framework and SDK can be installed from:
15:42:58       https://aka.ms/dotnet-download
15:42:58   - The following versions are installed:
15:42:58       2.0.6 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
15:42:58       2.0.9 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
15:42:58       2.1.2 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
15:42:58       2.1.3 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
15:42:58       2.1.4 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

As per the error message, we have installed the dotnet core SDK on the server but we seem to be missing something.

My test project looks like:

<Project Sdk="Microsoft.NET.Sdk">    
  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>    
    <IsPackable>false</IsPackable>
  </PropertyGroup>    
  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc.Core" Version="2.1.1" />
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.7.0" />
    <PackageReference Include="Moq" Version="4.10.0" />
    <PackageReference Include="RichardSzalay.MockHttp" Version="5.0.0" />
    <PackageReference Include="xunit" Version="2.3.1" />
    <PackageReference Include="xunit.runner.console" Version="2.4.0" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.3.1" />
    <DotNetCliToolReference Include="dotnet-xunit" Version="2.3.1" />
  </ItemGroup>        
</Project>

解决方案

版本控制是一个红鲱鱼，结果证明是一个简单得多的问题。我的测试正在测试异步控制器方法，而我的非异步测试正在执行：

var result = controller.PostAsync(request).Result;

一旦我将测试本身更改为使用 async/await 模式，它们就可以正常工作：

var result = await controller.PostAsync(request);

帮助我诊断问题的方法是使用dotnet test --verbosity d论点。使用它时，它会输出一些正在通过的测试，而不仅仅是“开始测试执行，请稍候”。有趣的是，每次我运行该命令时，它都会在出现卡住之前执行不同数量的测试。这表明可能存在某种线程死锁问题，导致我找到了解决方案。我仍然不确定为什么该命令在我的本地机器上运行良好，但不是我们的 Jenkins 代理。
