这个项目的 packages.config 文件是这样的:
在测试程序集构建步骤中使用的值:
执行选项
测试程序集:***Tests.dll;-:**obj**
启用代码覆盖:true
高级执行选项
VSTest:版本
VSTest 版本:最新
自定义适配器的路径为空，但工具提示指出自动搜索 Nuget 恢复的适配器.
报告选项
平台:$(BuildPlatform)
配置:$(BuildConfiguration)
所以它似乎(对我来说)它可以找到正确的文件(MyClassLibrary.Tests.dll)，但没有选择测试方法(标记为 [Fact] 或[理论]).
有人知道我做错了什么吗?
更新
解决方案中的所有项目都是.NET 4.5
我在切换到 xUnit 后遇到了同样的问题，经过多次反复试验和搜索，我发现 xUnit 测试运行程序只能在面向 .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).
这里的文档有点模糊，因为 xUnit 入门 指南并没有真正提到这一点，它只提到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，您正在测试的项目仍然可以面向 .NET 4.5.就我而言，我只是将我的测试程序集切换到面向 .NET 4.5.2，但所有其他项目仍然面向 .NET 4.5，并且运行良好.

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.core" version="2.2.0" targetFramework="net45" /> <package id="xunit.extensibility.core" version="2.2.0" targetFramework="net45" /> <package id="xunit.extensibility.execution" version="2.2.0" targetFramework="net45" /> <package id="xunit.runner.msbuild" version="2.1.0" 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
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.
