SimpleTest is all the rage in Drupal 7, and it's even finding its way into quite a few contrib modules for Drupal 6, not to mention its use at some big Drupal 6 projects, like the Economist. You can also integrate SimpleTest's test results into a Hudson setup using a script like the one provided by ComputerMinds.co.uk. (Tree House Agency has recently updated this script to work with SimpleTest 6.x-2.9 and submitted it to Pressflow and d.o proper.)
What if you're building an install profile and want to run SimpleTests against it? The default DrupalWebTestCase will install the default profile and any extra modules that you specify when the setUp() method is called.
Here is the skeleton of a subclass of DrupalWebTestCase that will install an install profile of your choice, and then test functionality inside of that install profile. Note that if you make any changes to the default profile installation form, they will not be accounted for when setUp() is called, since it will not be submitted.

To use, enter your profile name in the appropriate places, and then subclass this class to make a set of tests for your install profile.
Support for this has been integrated into the Pressflow mainline for quite some time.
