Xamarin.mac单元测试项目 [英] Xamarin.mac unit test project

问题描述

我正在尝试为Xamarin Mac类库项目创建一个单元测试项目.

I am trying to create a unit test project for a Xamarin Mac Class Library project.

.NET NUnit库项目无法正常工作，因为我无法添加对Xamarin Mac类库的引用，因此我尝试创建一个新的Xamarin Mac类库项目并向其添加了NUnit Nuget包.

.NET NUnit Library Project it doesn't work because I can't add a reference to my Xamarin Mac Class Library so I tried creating a new Xamarin Mac Class Library project and added NUnit Nuget package to it.

<package id="NUnit" version="3.5.0" targetFramework="xamarinmac20" />

它之所以起作用，是因为测试在测试管理器"中可见，但是不幸的是，每次我尝试运行单元测试时，都会收到加载失败"的消息.

For the first part it worked because the tests are visible in Test Manager but unfortunately every time I try to run the unit tests I receive "Load failed".

发生一个或多个错误.

推荐答案

Xamarin.Mac需要相当大的帮助才能将本机支持库放置在正确的位置/加载所有内容，然后确保只调用一次NSApplication.Init.，无论测试数量如何，等等.

Xamarin.Mac requires significant hand holding to place native support libraries in the right place / load everything up, and then assurance that you call NSApplication.Init only one time, no matter the number of tests, and so on.

让nunit做到这一点并非易事.我建议尝试 https://github.com/mono/guiunit .

Getting nunit to do that is non-trivial. I suggest trying https://github.com/mono/guiunit.

有两种使用guiunit的方法:

There are two ways to use guiunit:

• 将程序集与guiunit打包在一起并运行它们的传统方式: https://developer.xamarin.com/samples/mac/guiunit-example/
• 创建XM应用程序并直接包含guiunit的不太标准的方法:传统方法更易于集成到现有的nunit工作流程中，而更新的非标准方法则更易于调试.

  The traditional way is easier to integrate into existing nunit workflows, while the newer less standard way is easier to debug.
