TestNG BeforeClass BeforeMethod Test AfterClass AfterMethod

1.TestNG测试注解和Junit注解的不同以及生命周期：

TestNG测试的一个方法的生命周期：

                @BeforeClass（执行一次）

                @BeforeMethod（N个Test 方法执行N次）

                @Test Test方法（此注解可能在类上表示多个，在方法表示一个）

                @AfterMethod（N个Test 方法执行N次）

                @AfterClass（执行一次）

Junit4测试的一个方法的生命周期：

               @BeforeClass（执行一次）

              @Before（N个Test 方法执行N次）

               @Test Test方法

              @After（N个Test 方法执行N次）

              @AfterClass（执行一次）

2.测试@Test的使用范围和分组

下面为源代码自己看不解释：

3.TestNG参数化测试

        A.基于xml配置实现 需要@Parameters配合

        B.基于编码方式需要@Parameters配合

        C.基于Dataprovider数据提供者实现的。

        D.基于自定义数据提供者。

4.TestNG测试之间依赖

        A.测试分组，组间依赖   dependsOnGroups

        B.测试方法，方法名称之间的依赖   dependsOnMethods

5. TestNG @Factory测试工厂的设置

       主要设置针对测试单元的多次测试而言

6.TestNG并发测试和超时，异常的设置 threadPoolSize  singleThreaded         timeOut  expectedExceptions

7TestNG失败重新执行的策略

8TestNG和junit的整合

     A.junit3 采用反射实现调用和执行

    B.junit4采用JunitCore调用执行类。

9TestNG编码方式运行

       TestNG实现：

         

TestNG tng = new TestNG();
    tng.addListener( new MyMethodInterceptor());
    tng.setTestClasses(new Class[]{MyMethodInterceptorTest.class});
    tng.run();

Junit4实现：

  

JUnitCore.main(args);
tCore.runClasses(new class[]{Test.class,Test1.class});

10。TestNG通过注解Transformers 实现对运行时执行控制。

               主要实现IAnnotationTransformer 接口即可。

11.TestNg方法拦截器的可以修改执行的结果信息。

              主要实现IMethodInterceptor接口即可。

12 TestNG丰富的Listener监听器满足不同阶段的监听。

  IAnnotationTransformer  
  IAnnotationTransformer2  
  IHookable  
  IInvokedMethodListener  
  IMethodInterceptor  
  IReporter  
  ISuiteListener  
  ITestListener 

13.TestNG的依赖注入和不同框架的整合

    Spring，Guide等使用。

14.TestNG结果的监听和执行报告和日志的控制
