C#版本的xUnit的测试框架模型和xUnit.NET开源项目

1. 参考kent beck的测试驱动写的C#测试框架模型

a) 测试用例： WasRun, 基类为TestCase

b) 框架： TestCaseTest用来测试TestCase，本身也是它的子类，可使用run调用自己的方法

c）重点：为WasRun和TestCase，添加setUp，tearDown功能

d）然后，TestResult用来返回和传递结果，主要是计数的结果

e) 最后，TestSuite封装一组测试，并在TestCaseTest中测试

WasRun<=>TestCase<=>TestSuite<=>TestCaseTest<=> Main

2.另外开源完整的测试框架可参考这里 https://github.com/xunit/xunit

贴上模型的代码，大家自己按类区分吧。

namespace xUnit
{
    class Program
    {
        static void Main(string[] args)
        {
            //(new TestCaseTest("testTemplateMethod")).run();

//(new TestCaseTest("testTemplateMethod")).run();
            //(new TestCaseTest("testResult")).run();
            //(new TestCaseTest("testFailedResultFormatting")).run();
            //(new TestCaseTest("testFailedResult")).run();

(new TestCaseTest("testSuite")).run(new TestResult());

Console.ReadLine();
        }
    }
}

namespace xUnit
{
    class TestResult
    {
        private int runCount;
        private int errorCount;
        public TestResult()
        {

            errorCount = 0;
        }
        public string summary()
        {
            string sumStr = "" + runCount + " run, " + errorCount + " failed";
            return sumStr;
        }

            runCount++;
        }

        {
            errorCount++;
        }
    }
