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
