1,演示环境:windows 10企业版+Visual Studio 2019;.NET Core3.1;xUnit 2.4.1;.NET Standard 2.0.3
2,日期:2020/03/20
3,场景描述:测试调用目标微服务的暴露的某个模块的接口;需要按顺序执行创建表,查询表,修改表,删除表接口;
本文只粘贴了核心的代码,详细demo代码地址可以前往github下载:https://github.com/SaorenXi/XunitTestDemo.git
4,思路:在xUnit的xunit.core程序集中的Xunit.Sdk命名空间下;有一个用于控制执行顺序的接口:ITestCaseOrderer
如下代码为原程序集定义:
#region 程序集 xunit.core, Version=2.4.1.0, Culture=neutral, PublicKeyToken=8d05b1bb7a6fdb6c // C:\Users\Administrator\.nuget\packages\xunit.extensibility.core\2.4.1\lib\netstandard1.1\xunit.core.dll #endregion using System.Collections.Generic; using Xunit.Abstractions; namespace Xunit.Sdk { // // 摘要: // A class implements this interface to participate in ordering tests for the test // runner. Test case orderers are applied using the Xunit.TestCaseOrdererAttribute, // which can be applied at the assembly, test collection, and test class level. public interface ITestCaseOrderer { // // 摘要: // Orders test cases for execution. // // 参数: // testCases: // The test cases to be ordered. // // 返回结果: // The test cases in the order to be run. IEnumerable<TTestCase> OrderTestCases<TTestCase>(IEnumerable<TTestCase> testCases) where TTestCase : ITestCase; } }
5,为了做方法顺序控制;定义一个名为OrderAttribute属性标签,标签上有个名为Sort的int型属性,用于标记方法的顺序;如下定义(示例是定义在:XUnitTest.Orders命名空间下)
using System; namespace XUnitTest.Orders { /// <summary> /// 测试方法的执行顺序 /// </summary> [AttributeUsage(AttributeTargets.Method)] public class OrderAttribute : Attribute { /// <summary> /// 顺序 /// </summary> public int Sort { get; set; } public OrderAttribute(int sort) { this.Sort = sort; } } }
6,实现ITestCaseOrderer接口(//按照Order标签上的Sort属性,从小到大的顺序执行),如下定义(示例定义在:SchemaTest命名空间下)
using System.Collections.Generic; using System.Linq; using Xunit.Abstractions; using Xunit.Sdk; using XUnitTest.Orders; namespace SchemaTest { /// <summary> /// 单元测试的排序策略 /// </summary> public class TestOrders : ITestCaseOrderer { /// <summary> /// 执行顺序 /// </summary> /// <typeparam name="TTestCase"></typeparam> /// <param name="testCases"></param> /// <returns></returns> public IEnumerable<TTestCase> OrderTestCases<TTestCase>(IEnumerable<TTestCase> testCases) where TTestCase : ITestCase { string typeName = typeof(OrderAttribute).AssemblyQualifiedName; ; var result = testCases.ToList(); result.Sort((x, y) => { var xOrder = x.TestMethod.Method.GetCustomAttributes(typeName)?.FirstOrDefault(); if (xOrder == null) { return 0; } var yOrder = y.TestMethod.Method.GetCustomAttributes(typeName)?.FirstOrDefault(); if (yOrder == null) { return 0; } var sortX = xOrder.GetNamedArgument<int>("Sort"); var sortY = yOrder.GetNamedArgument<int>("Sort"); //按照Order标签上的Sort属性,从小到大的顺序执行 return sortX - sortY; }); return result; } } }
7,使用;在目标的单元测试类上打上标签使用顺序执行实现类的标签;如下定义(示例中的目标类为:SchemaTest命名空间下的SchemaApiTest类)
//省略其他代码 using Xunit; using XUnitTest.Orders; namespace SchemaTest { //[TestCaseOrderer("ITestCaseOrderer的实现类名称", "ITestCaseOrderer的实现类所在的程序集名称")] [TestCaseOrderer("SchemaTest.TestOrders", "SchemaTest")] public class SchemaApiTest { //省略其他代码 } }
8,在目标的测试方法上打上Order标签,定义执行顺序,如下定义(示例使用的是mock数据和接口)
using Xunit; using XUnitTest.Orders; namespace SchemaTest { [TestCaseOrderer("SchemaTest.TestOrders", "SchemaTest")] public class SchemaApiTest { private string _testSchemaCode = $"xunittest123"; private static SchemaDTO _schemaDto = null; /// <summary> /// 创建记录 /// </summary> [Fact, Order(1)] public void AddSchema() { var response = new MockClient().AddSchema(new SchemaDTO { SchemaCode = _testSchemaCode, Name = "哈哈" }); Assert.True(response); } /// <summary> /// 查询刚刚创建的记录 /// </summary> [Fact, Order(2)] public void GetSchema() { var response = new MockClient().GetSchema(_testSchemaCode); //临时记录 _schemaDto = response; Assert.NotNull(response); Assert.Equal(_testSchemaCode, response.SchemaCode); Assert.Equal("哈哈", response.Name); } /// <summary> /// 更新刚刚创建的数据记录 /// </summary> [Fact, Order(3)] public void UpdateSchema() { _schemaDto.Name = "jiujiu"; var response = new MockClient().UpdateSchema(_schemaDto); Assert.True(response); } /// <summary> /// 查询更新后的记录 /// </summary> [Fact, Order(4)] public void GetAfterUpdatedSchema() { var response = new MockClient().GetSchema(_testSchemaCode); Assert.NotNull(response); Assert.Equal(_testSchemaCode, response.SchemaCode); Assert.Equal("jiujiu", response.Name); } /// <summary> /// 删除记录 /// </summary> [Fact, Order(5)] public void RemoveSchema() { var response = new MockClient().RemoveSchema(_testSchemaCode); Assert.True(response); } } }
9,测试
