iPhone Unit Testing Toolkit
As we get in to developing iPhone/Touch applications at Carbon Five, we obviously want to bring over all our best agile practices including test driven development (TDD). I’ve been bootstrapping with the beta version of the Pragmatic iPhone SDK Development book but was disappointed to find no discussion of unit testing for the iPhone. So …
Database Testing with Spring 2.5 and DBUnit
Note: Version 0.9.1 of c5-test-support has been released. We’ve been using DB Unit on our Java projects for years and the mechanics of how it’s used has evolved over time. I’ve recently spent some time making it work a little nicer for how we typically write database tests. What I’ve created makes using DBUnit on …

Here’s …
DBUnit 2.2, Spring, and Testing

Since then I’ve discovered what the problem was and found a workaround, and while I was at it, …
Generic Custom Argument Matching in EasyMock

It provides a whole range of facilities for declaring our expectations of the method call interactions on the mock including call count, call order, return values, exceptions, and argument matchers. Unfortunately, the argument matchers provide a limited set of argument expectations and a somewhat cumbersome …
DBUnit, HSQL and the BOOLEAN data type
We have been using HSQL in-memory along with DBUnit for unit testing lately, and I found an issue using the most recent version of each. Basically, HSQL has added a new data type, BOOLEAN, which replaces BIT. But DBUnit is not updated to support this, and an error is throw when you attempt to insert …
