VS自身的单元测试方法DEMO

 ///用来修饰测试类

        [TestMethod()]
        public void Add()
        {
            bool t = a == 10;
            Assert.AreEqual(true, t);
        }

        [TestMethod()]
        public void Sub()
        {
            int a = 0;
            int b = 10 / a;
            Assert.AreEqual(true, true);
        }
        public void Ignore()
        {
            Assert.AreEqual(true, true);
        }


    }

区别 VS没有Ignore，没有异常属性
