Spring：如果无法扩展AbstractTestNGSpringContextTests，如何在Testng测试类中获取spring applicationContext

Question

My test already extends an abstract BaseIntegrationTest class, so can't extends AbstractTestNGSpringContextTests class - as we normally do with Testng Spring integration tests, and I don't want my BaseIntegrationTest to load the spring application context (by extends AbstractTestNGSpringContextTests ) because there are a lot more sub-class tests that don't need the context (which has a DB entity), and most of the time I will exclude current test that requires the DB connection for integration test. So once in a while I need to run this Testng based test, which extends some class already and still needs to contextAware (I have tried implements ApplicationContextAware which doesn't work for me, maybe I was doing it it wrong?). How would you do it?

That's just how Spring integrates with TestNG - you have to extend AbstractTestNGSpringContextTests . Alternatively you can manually instantiate Spring in your tests:

new ClassPathXmlApplicationContext("context1.xml", "context2.xml")

But that won't allow you to use other kind of annotations like @Transactional . Potentially you could write your own integration with Spring over TestNG listeners (hm.. why Spring didn't use it instead?), but that's going to take some time to implement and debug :)

Also, I'd like to mention that extending your own base classes is not a good idea . Though it's very common unfortunately. A much better (easier to read, OOP-friendlier) way would be to create separate classes and functions with your common logic. And then invoke those explicitly in your tests.
