NUnit 测试适配器：为什么单个测试执行多次？

Question

我有一个非常基本的测试示例，使用 NUnit 3.0.1、NUnitTestAdapter.WithFramework 2.0.0 和 RestSharp 105.2.3，在 VisualStudio 2015 中用 C# 编写。使用 NUnit 测试适配器运行测试时，我的测试被执行了 2 次1。似乎有 2 个测试适配器并行运行。可能是什么原因？当然，我希望它只运行一次。提前致谢！

using NUnit.Framework;
using RestSharp;
using System;

namespace Project1.Tests
    {
        public class Test1
        {
            [Test]
            public void GetTest()
            {
                var client = new RestClient("http://www.thomas-bayer.com/sqlrest/");
                var request = new RestRequest("CUSTOMER", Method.GET);
                var queryResult = client.Execute(request);
                Console.Write("result: " + queryResult.Content.Length);
                Assert.IsTrue(queryResult.Content.Length > 0);
            }
        }
    }

结果：

NUnit VS Adapter 2.0.0.0 discovering test is finished
NUnit VS Adapter 2.0.0.0 discovering test is finished
A test with the same name 'Project5.Tests.Test1.GetTest' already exists. This test is not added to the test window.

Answer 1

如果您的 NUnit 版本是 3.0.1，为什么要使用 NUnit Adapter v2？

Answer 2

您同时拥有 Visual Studio 扩展和 NUnit Test Runner 的 NuGet 包。

从 Visual Studio 扩展中删除了测试适配器。 在工具菜单上，单击扩展管理器。 在扩展管理器中找到测试适配器并单击禁用或卸载。
