将SQL Server单元测试项添加到Visual Studio 2017中的单元测试项目时出错

Question

将Visual Studio单元测试项添加到Visual Studio 2017中的单元测试项目时,我收到以下错误:

The reference "Microsoft.VisualStudio.QualityTools.UnitTestFramework, 
Version=15.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a, 
processorArchitecture=MSIL" could not be added to the project. 
This wizard will continue to run, but the resulting project may not build properly.

该项目似乎在之后构建良好,但所有sql单元测试失败并出现以下错误:

Test Name:  SqlTest1
Test FullName:  UnitTestProject1.SqlServerUnitTest1.SqlTest1
Test Source:    c:\[path]\SqlServerUnitTest1.cs : line 34
Test Outcome:   Failed
Test Duration:  0:00:00.0278356

Answer 1

这似乎与自动引用的包中的测试工具的不匹配版本有关.

这是我做的修复它:

1. 删除项目的引用Microsoft.VisualStudio.TestPlatform.TestFramework和Microsoft.VisualStudio.TestPlatform.TestFramework.Extensions从项目中删除引用.

2. 然后添加一个新的引用Microsoft.VisualStudio.QualityTools.UnitTestFramework.您可以在参考对话框的Assemblies - > Extensions列表中找到它.您可能会发现有两个副本,都列为版本10.1.0.0.在这种情况下,你应该检查每个的文件版本,你会发现一个是14.0.23107.0,一个是15.0.26228.0这是你想要的15.x.

更改这些参考后,一切都很好.
