Groovy动态语言 运行在JVM中的动态语言 可以方便的处理业务逻辑变化大的业务

				package groovy.mock.example
				
				class CheeseSlicer {
				
				    void slice(String name) {
				        throw new RuntimeException('whatever nasty behavior that needs to be mocked...')
				    }
				
				    void coffeeBreak(String name) {
				        // dum didum didum *slurp*, *spill*
				    }
				
				}
