Google have a nice equals method to make boiler plate equals easier to read. Particularly good if you have many attributes in the method. http://publicobject.com/2007/09/coding-in-small-with-google-collections_8175.html
Be careful to check that your objects are consistent with equals though. I have mentioned this before.

Test anti-patterns project, contributors wanted!
I deliberately wrote a poor quality test, so that I could show how easy it is to re-factor it to a better one. I was driven by having seen lots of such poor tests and to be honest I don’t want to see another of its ilk again. I might write a test like this myself, but I would never leave it like this. Its part finished, littered with cut and paste, poorly named methods and hard coded values.
I show how to re-factor the test using several patterns for test fixtures. The setup stage is often the worst bit of a bad test. If you want to contribute some of your own bad tests and example improvements, read the blog, download the project and contribute!
