So the @Timed annotation will fail if the test takes more than the milliseconds parameter provided. Maybe you want to test some process time that should not take too long or maybe you need to test the response of the external call to another system that should not exceed the time you specified. And the @Repeat annotation will repeat the test as many times as the number provided. You can use the @Repeat in a test when you need to measure the average of process executing by repeating the same test several times. Summary In this chapter, I covered the Spring Framework Testing extension. You discovered how easy it is to use it. In previous chapters, you instantiated the ApplicationContext with the ClassPathXMLApplicationContext class and every time you needed a bean you had to call the getBean method. But thanks to the annotations provided by the Spring Framework Test extension, you can have better readable code and faster development because you can focus on the test cases. If you download the companion source code, you can find other versions of the classes, which convert to the Spring Test extension, even the Groovy classes. 85
