Efficient way of GUI testing in java

I need to do write testing code for GUI. I am using Jsp,java, JavaScript. I am running the testing GUI in browser, and doing some action on its, for eg. search . And than matching that source code with the expected code. This is taking really much time. And I have huge number of files. It takes around 2 hours to test every time, which is very inconvenient. Is there any efficient way Or any Improvement/ Suggestion. I attached one of my testing class.
