Visual Studio 2017中的Xamarin（Android）单元测试 [英] Xamarin (Android) Unit Tests in Visual Studio 2017

问题描述

我正在使用Visual Studio 2017开发Xamarin Android应用程序。我只想添加逻辑的简单单元测试。为此，我尝试添加带有单元测试的单元测试应用程序（Android）或类库（Android）项目，但它们都不起作用。

I'm using Visual Studio 2017 to develop Xamarin Android application. I want to add simple unit tests of logic only. For that purpose, I tried adding "Unit Test App (Android)" or "Class Library (Android)" projects with unit tests and none of them work.

我将新项目添加到类型为单元测试应用程序（Android）的解决方案中。生成的项目包含带有示例测试的 TestsSample 类，但是我不知道如何启动它们。我已经安装了ReSharper，但是右键单击项目/类时，我没有选择运行测试。
当我转到测试->运行->所有测试时，解决方案已构建，但是什么也没有发生。

I add new project to my solution of type "Unit Test App (Android)". Generated project contains TestsSample class with sample tests, but I have no idea how to launch them. I have ReSharper installed, but when right clicking on the project/class I don't have option to run the tests. When I go to "Test" -> "Run" -> "All tests", the solution is built, but nothing more happens.

另一个试验是向解决方案中添加类型为类库（Android）的新项目。之后，我安装了nUnit nuget软件包（ install-package nunit ），该软件包针对项目 MoneyBack.Tests安装了软件包 nunit.3.6.1，目标是 MonoAndroid，Version = v6.0'），则安装成功。

The other trial was to add new project of type "Class Library (Android)" to the solution. After, I installed nUnit nuget package (install-package nunit which installed package 'nunit.3.6.1' with respect to project 'MoneyBack.Tests', targeting 'MonoAndroid,Version=v6.0'), installation was successful.

我添加了以下类：

using NUnit.Framework;

namespace MoneyBack.Tests
{
    [TestFixture]
    public class Class1
    {
        [Test]
        public void SampleTest()
        {
            Assert.IsTrue(true);
        }
    }
}

现在在右键单击时在测试项目中，我看到了ReSharper的选项运行单元测试，因此我单击了它并得到以下异常：

Now when right-clicking on the tests project I see ReSharper's option "Run Unit Tests", so I clicked it and got the following exception:

难道我做错了什么 ？还是VS2017的问题？我不知道是否应该重新安装VS2015或有一些解决方案。谢谢您的帮助！

Am I doing something wrong ? Or it's the issue with VS2017 ? I don't know if I should install VS2015 back or there is some solution. Thanks for your help!

推荐答案

测试分为三个基本级别：

There are three basic levels of testing:

• 这里没有什么新鲜的东西，这与.Net程序员长期以来所做的测试相同并且与Xamarin平台框架无关

注意：这些测试与完全不相关 Xamarin.Android | iOS | Mac

Note: These tests are totally independent of Xamarin.Android|iOS|Mac

注意： NUnit，XUnit等的设备测试包装器。Xamarin包含一个 NUnitLite 版本，该版本可在 Android 和<$上运行c $ c> iOS 并提供设备特定的UI来运行这些测试。 Xamarin的模板可为Android或iOS创建 Unit Test App 项目。

Note: There are multiple on device testing wrappers for NUnit, XUnit, etc... Xamarin includes a NUnitLite version that runs on Android and iOS and that provide a device specific UI to run those tests. Xamarin has templates that create a Unit Test App project for Android or iOS.

注意：这些测试可以包含平台相关的功能（网络，蓝牙，GPS，SMS等...，但不包括与GUI相关的测试），还可以引用用PCL-编写的Nunit [Test] 基于程序集或平台特定的库。

Note: These tests can include platform dependent features (Networking, Bluetooth, GPS, SMS, etc... but no GUI related tests) and can also reference Nunit [Test]s written in PCL-based assemblies or platform-specific libraries.
