Java user agent parser

I was searching for a good Java USerAgent parser and I found http://use开发者_StackOverflow中文版r-agent-utils.java.net/

How can I test it to see if I get the correct results?

You can get a look at UADetector, it seems better supported than user-agent-utils (up to date parser, actively developed, monthly releases)

One of they official tests can be seen here
