NUnit for Portable Class 库测试

Question

尝试运行测试使用 NUNit 在常规 PCL 库中编写的测试。它只是一个空项目，只有一个测试什么都不做。

NUnit 控制台运行ner 显示消息

The NUnit 3.0 driver does not support the portable version of NUnit. Use a platform specific runner.

并且 Resharper 运行ner 崩溃并显示消息

Unit Test Runner failed to run tests

和堆栈跟踪：

根据 this 的评论，PCL 应该可以，但没有。如果我们在没有 Xamarin 的情况下使用 PCL，执行测试的选项是什么？

Answer 1

要运行可移植测试，您需要使用 NUnitLite to create a self-executing test runner. Basically, you create a .NET 4.5.x console application, reference NUnitLite and your test assembly. You then run the console application to run your tests. See Testing .NET Core using NUnit 3 作为步骤，除了它使用 .NET Core 而不是 .NET 4.5 来运行测试。

如果您正在测试的程序集是 PCL 但目标是 .NET 4.5，则更简单的方法是将测试程序集创建为 .NET 4.5.x 并引用 PCL 正在测试的组件。这将使您的测试引用 NUnit 框架的完整版本，并允许您运行在 Visual Studio 中或使用 Resharper 进行测试。仅仅因为您正在处理的代码是 PCL，并不意味着您的测试需要是 PCL.
