Test assemblies构建步骤中使用的值:

执行选项

测试程序集:**\*Tests.dll;-:**\obj\**

高级执行选项

VSTest:Version
VSTest版本:Latest

自定义适配器的路径为空，但工具提示显示为Nuget restored adapters are automatically searched for.

报告选项

平台:$(BuildPlatform)
配置:$(BuildConfiguration)

在我看来，它可以找到正确的文件(MyClassLibrary.Tests.dll)，但没有使用测试方法(标记为[Fact]或[Theory]的测试方法)./p>

有人知道我做错了什么吗?

更新

解决方案中的所有项目均为.NET 4.5

解决方案

在经过反复试验和搜索之后，我切换到xUnit之后遇到了同样的问题，我发现xUnit测试运行程序只能是在针对.NET 4.5.2或更高版本的程序集中运行，否则无法加载(因此将找不到测试).

这里的文档有点含糊，因为 xUnit入门指南并没有真正提及这一点，它仅提及创建一个新的类库项目针对.NET 4.5.2(或更高版本)" .

但这仅适用于包含实际测试的程序集，正在测试的项目仍可以针对.NET 4.5.就我而言，我只是将测试程序集切换到.NET 4.5.2，但是所有其他项目仍然以.NET 4.5为目标，并且效果很好.

The packages.config file for this project is this:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  ...
  <package id="xunit" version="2.2.0" targetFramework="net45" />
  <package id="xunit.abstractions" version="2.0.1" targetFramework="net45" />
  <package id="xunit.assert" version="2.2.0" targetFramework="net45" />

  <package id="xunit.runner.visualstudio" version="2.2.0" targetFramework="net45" developmentDependency="true" />
</packages>

The values used in the Test assemblies build step:

Execution options

Test assembly: **\*Tests.dll;-:**\obj\**
Code coverage enabled: true

Advanced Execution options

VSTest: Version
VSTest version: Latest

Path to custom adapters is empty, but the tooltip states Nuget restored adapters are automatically searched for.

Reporting options

Platform: $(BuildPlatform)
Configuration: $(BuildConfiguration)

So it seems (to me) that it can find the proper file (MyClassLibrary.Tests.dll), but doesn't pick up the test methods (which are marked as [Fact] or [Theory]).

Anybody has an idea what I do wrong?

update

All projects in the solution are .NET 4.5

解决方案

I had the same issue once I made the switch to xUnit, after lots of trial-and-error and searching I found that the xUnit test runner can only be run in an assembly targeting .NET 4.5.2 or above, otherwise it cannot be loaded (and thus the tests will not be found).

The documentation is a bit vague here, since the Getting Started with xUnit guide doesn't really mention this, it only mentions to create a new class library project "targeting .NET 4.5.2 (or later)".

But this is only for the assembly containing the actual tests, your projects being tested can still target .NET 4.5. In my case I simply switched my test assemblies to target .NET 4.5.2, but all the other projects still target .NET 4.5 and it works very well.
