(20) Increase unit testing for SpringAppController
l SpringAppController depends on HttpServletRequest, HttpservletResponse, and application Context
l The controller does not use Request and Response, so it is simply set to null
l Application Context can be loaded outside of the web container, here FileSystemXmlapplicationContext

}
}
l This is just testing the handleRequest method, check the data returned in Model.
l Load the application context in the setup method; copy the springapp / web-inf / springapp-servlet.xml to the src / web - web-inf directory, remove Messagesource, Urlmapping, ViewResolver entry L (Translator: Eclipse) JUnit, so it is easy to perform unit testing in Eclipse)
(21) Increase unit testing and new features to ProductManager
l Increaseprice in ProducTManager increasing growth price ()
