3.Category的用法：測試用例分組，看看下面的代碼和結(jié)果清楚了

using System;
using System.Text;
using NUnit.Framework;

namespace NUnitTest
{
    [TestFixture]
    public class CaculatorTest
    {
        private Caculator cac;
        private int a;
        private int b;

        /// <summary>
        /// 聲明為TestFixtureSetUp的方法將在所有選中的TestCase調(diào)用之前調(diào)用，通常用來初始化數(shù)據(jù)庫連接

        public void InitUtility()
        {
            Console.Write("Caculator Invoked!");

        }

        [TearDown]
        public void Destroy()
        {

            Assert.AreEqual(8， result);

        [Test]

運(yùn)行結(jié)果：

若選中Exclude these Category，運(yùn)行結(jié)果
