使用 Xunit 运行单元测试

Question

I have added a unit testing class and added the below references to my main class library in the UWP project.

When I add a new class library and add my test classes there the test methods on the class library execute but the test methods on the main project throw the below exception.

System.InvalidOperationException: The following test container was not found: 'F:\test\WinApp\bin\x64\Debug\WinApp.exe'. This can be resolved by one or more of the following steps:
1. The test container does not exist on disk and the corresponding project might need to be built successfully.
2. For .NET Core based test projects, please ensure that a nuget package reference to "Microsoft.NET.Test.SDK" exists and that it uses the latest stable version.
3. For .NET based test projects, the project might be marked as a non-test project through an msbuild property, "IsTestProject". Please consider clearing it or set "<IsTestProject>true</IsTestProject>" in a "<PropertyGroup>" in the test project.

I tried the above approaches but no use.

I want to write my test classes inside my main class library which is executable any suggestions.I am trying this as I cannot add references to the main class library from the test project and run it.Below error throws if I try to do so.

My test project is a Unit Test App(Universal Windows)

I am not running in a build server

Answer 1

A conflict is occurring since there are 2 Default.rd.xml files are available for the project.

A runtime directives (.rd.xml) file is an XML configuration file that specifies whether designated program elements are available for reflection. (Reference: Runtime Directive Documentation by Microsoft

So, if your Unit Test Project isn't using Reflection, then it should be safe to remove Default.rd.xml file from the Test Project (the one in F:\test\UnitTestProject2\Properties).

Do a complete rebuild and you should be good to go.
