It's beyond twenty years since Tim O'Reilly published my little book Checking C Programs with Lint. So much has changed! In those days short books went out on paper as Nutshell Books; now they go out as Short Cut ebooks. In those days C was the leading programming language; today Java is one of the leaders, with others nipping at its heels. But one thing hasn't changed, and it hasn't changed since the days of Grace Murray Hopper: programs still have bugs. Programmers still write code with bugs. Users still find bugs in software.
While Java does a lot to prevent bugs from forming (Java's garbage collection gets rid of the majority of memory allocation and deallocation bugs), it certainly does not do everything. There is still room for additional tools to help you find bugs in your software, and for a book that tells you about some of these tools.
So. This site is about my O'Reilly e-book in this area, Checking Java Programs with Open Source Tools.
The book covers a number of topics but the major ones are:
I did not cover Program Testing with JUnit in the 2007 book as there is enough coverage in that area already. I do cover it in the video class. There is also a short section on it in my Java Cookbook.. There was comprehensive coverage in J. B. Rainsberger's excellent JUnit Recipes (Manning, 2004)), but that book covers the ancient 3.x line of JUnit, whereas the world has moved on, to JUnit 4.
