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.我只想添加简单的逻辑单元测试.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.

我将新项目添加到单元测试应用程序(Android)"类型的解决方案中.生成的项目包含带有示例测试的 TestsSample 类，但我不知道如何启动它们.我安装了 ReSharper，但是当右键单击项目/类时，我没有运行测试的选项.当我转到测试"->运行"->所有测试"时，解决方案已构建，但什么也没有发生.

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.

另一个试验是将类库(Android)"类型的新项目添加到解决方案中.之后，我安装了 nUnit nuget 包(install-package nunit，它安装了关于项目MoneyBack.Tests"的包nunit.3.6.1"，目标是MonoAndroid,Version=v6.0")，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，当右键单击测试项目时，我看到 ReSharper 的选项运行单元测试"，因此我单击它并得到以下异常:

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:

我做错了吗?还是 VS2017 的问题?我不知道我是否应该重新安装 VS2015 或者有一些解决方案.感谢您的帮助！

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:

• 这里没有什么新鲜事，这与 .Net 程序员一直在做的测试相同，与 Xamarin 平台框架无关

注意:这些测试完全独立Xamarin.Android|iOS|Mac

注意:有多个用于 NUnit、XUnit 等的设备测试包装器... Xamarin 包括一个在 Android 和 iOS<上运行的 NUnitLite 版本/code> 并提供特定于设备的 UI 来运行这些测试.Xamarin 具有为 Android 或 iOS 创建单元测试应用项目的模板.

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:这些测试可以包括平台相关的功能(网络、蓝牙、GPS、SMS 等...但没有与 GUI 相关的测试)，也可以参考用 PCL 编写的 Nunit [Test]s-基于程序集或特定于平台的库.

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.

• xUnit.net 设备运行程序
• 适用于 Xamarin 和移动设备的 NUnit 测试运行器
