TODO 设计原理和实现
TestContextManager ： Spring TestContext Framework的主入口，管理单例的TestContext和所有注册的TestExecutionListeners。 TestContext TestExecutionListener ContextLoader
Context management
每个TestContext提供 context 管理， 测试实例无权配置ApplicationContext， 实例仅能获得一个ApplicationContext的引用。特别的是AbstractJUnit4SpringContextTests和AbstractTestNGSpringContextTests实现了ApplicationContextAware而且有权修改ApplicationContext。

Spring JUnit Runner

如果要使用MockitoJUnitRunner等第三方runners， 可以使用Spring JUnit Rules。
