MSTest和Xunit细节区别

1.多实例参数化测试
Xunit参数不匹配会报错，MSTest不会；

//MSTest
public class Solution103Tests
    {
        [TestMethod()]
        [DataRow(new object[]{ 3, 9, 20, null, null, 15, 7 },2,"2" )]//这里测试参数不匹配无法调试测试，而Xunit参数不匹配会报错
        public void ZigzagLevelOrderTest(object[] array)
        {
            //Arrange 
            var expected =
                new List> {new List() {3}, new List() {20, 9}, new List() {15, 7}};
            //Act
            var actual = new Solution103().ZigzagLevelOrder(array.CreateTree());

            //Assert
            for (int i = 0; i < actual.Count; i++)
            {
                Assert.IsTrue(expected[i].SequenceEqual(actual[i]));
            }

            Assert.That.SequenceEqual2(expected, actual, "You are wrong!!!");
            Assert.AreEqual(expected.Count, expected.Count, "You are wrong!!!");
            var typ = expected.GetType();
            Assert.IsInstanceOfType(actual, typ);

        }
    }

2.MSTest是单例模式，Xunit构造函数protect修改
这导致MSTest.That有更好的扩展性；

using System.Collections.Generic;
using System.Linq;
using Microsoft.VisualStudio.TestTools.UnitTesting;

{
    public static class AssertExtend
    {
        /// 
        /// list判断内容是否相等
        /// 
        /// 
        /// Examples
        /// Assert.That.SequenceEqual(list1, list2, "You are wrong!!!");
        /// 
        /// Assert.That单例
        /// 集合1
        /// 集合2
        /// 错误信息
        public static void SequenceEqual(this Assert assert, IList list1, IList list2, string msg)
        {
            if (list1.Count != list2.Count)
                Assert.Fail(msg);
            var ok = list1.SequenceEqual(list2); 
            Assert.IsTrue(ok, msg);
        }

        /// 
        /// 嵌套list判断内容是否相等
        /// 
        /// 
        /// Examples
        /// Assert.That.SequenceEqual2(list1, list2, "You are wrong!!!");
        /// 
        /// Assert.That单例
        /// 集合1
        /// 集合2
        /// 错误信息
        public static void SequenceEqual2(this Assert assert, IList>? list1, IList>? list2, string msg)
        {
            if (list1 == null || list2 == null)
                Assert.Fail(msg);
            if (list1.Count != list2.Count)
                Assert.Fail(msg);
            var ok = true;
            for (int i = 0; i < list1.Count; i++)
            {
                ok = ok && list1[i].SequenceEqual(list2[i]);
            }
            Assert.IsTrue(ok, msg);
        }
    }
}
