Unit testing in Delphi - how are you doing it?

I'm wondering how the few Delphi users here are doing unit testing, if any? Is there anything that integrates with the IDE that you've found works well? If not, what tools are you using and do you have or know of example mini-projects that demonstrate how it all works?

Update:

I forgot to mention that I'm using BDS 2006 Pro, though I occasionally drop into Delphi 7, and of course others may be using other versions.

DUnit is a xUnit type of unit testing framework to be used with win32 Delphi. Since Delphi 2005 DUnit is integrated to a certan point into the IDE. Other DUnit integration tools for the Delphi IDE can be found here. DUnit comes with documentation with examples.

There are some add-ons for DUnit, maybe this is worth a new entry on SO. Two which I can put on the list now are

  1. FastMM4 integration: Unit tests will automatically detect memory leaks (and other things), works with DUnit 9.3 and newer
  2. OpenCTF is a 'component test framework' based on DUnit, it creates the tests dynamically for all components in the project's forms, frames and datamodules, and tests them using customized rules (open source)

Usually I create a Unit test project (File->New->Other->Unit Test->Test Project). It contains the stuff I need so it's been good enough so far.

I use delphi 2007 so I don't really know if this is available in 2006.

We do unit testing of all logic code using DUnit and use the code coverage profiler included in AQTime to check that all paths through the code are executed by the tests.

We have two approaches, first we have Dunit tests that are run buy the developers - these make sure that the code that has just been changed still works as before. The other approach is to use CruiseControl.NET to build executables and then run the dunit tests everytime a change is made, to ensure that there are no unintended consequences of the change.

Much of our codebase has no tests, so the automatic tests are a case of continuous development in order to ensure our applications work as we think they should.

We tried to use DUnit with Delphi 5, but it didn't work well. Specially if you are implementing COM interfaces, we found many dependencies to setup all the test infrastructure. I don't know if the test support has improved in newer versions.
