Over the last 6+ months, I have been using Hudson in conjunction with Windmill very heavily for continuous integration. For the most part using the build step specific to whatever the slave OS requires has worked sufficiently well until recently when my needs changed.

I use the ‘configuration matrix’ option to build a matrix of browsers to run the tests, this way I can have one job that represents a test run on multiple boxes and multiple browsers on each box. Drilling down allows me to see the results for each of these test runs within the job. (Configuration Matrix is awesome btw, except for one really annoying bug for, which there is a reasonable workaround)

Having many build resources, sometimes I want to move a job from one machine to another in order to equalize load on the different machines or to have a job running in ff2 and ie6 instead of ff3 and ie7. Thus the need for a uniform build step that will run the same way regardless of the machine or installed browsers, became necessary. Additionally the commands for running tests got bigger and less manageable all the time, so the time for a clean user interface finally came. This way I can automatically append arguments like ‘exit’ to keep the build step interface simple and clean.

The other simplification is that in the Hudson configuration page for the Windmill Test plug-in you can tell it to automatically call the contrib ‘clean_run.py’ script with the correct arguments (assuming clean_run.py can be found in your path).

As I am relatively new to the Java world, I struggled through the development process but thanks to some reasonable plug-in documentation, responses from the hudson dev mailing list and some IRC conversations with Kohsuke (thanks so much) I finally have something that sufficiently addresses my needs.

Project

The code is all available on GitHub and I welcome any improvements or input from the community as I know that continuous integration is a very important piece of the utility provided by Windmill and this pieces should be as easy as possible to setup.

The combination of this plug-in, and others like the amazon s3 plug-in or the hudson VMware plugin bring us that much closer to seamlessly creating test resources, running our functional web tests across all of our supported platforms and then throwing it away until it’s again needed (or using the CLOUD).I have also done some integration with virtual box that I have found to be very successful.
