James, using sugar-launch, do you think I could get a hold of any output the activity writes to stdout? I've been thinking that maybe I could have a test mode where the activity would run tests internally and report the results to stdout. The test program would just parse the output then... -Taylor <div class="gmail_quote">On Thu, May 3, 2012 at 3:56 PM, James Cameron <<a href="mailto:quozl@laptop.org" target="_blank">quozl@laptop.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> I have not seen any activity with unit tests. I have seen and maintained Python code with tests that are implemented as conditional blocks at the end of each source file except the main source file. These conditional blocks are predicated on execution of the file alone, and not on import. The main source file was in the directory above, with all the imported files in a directory below. So running the tests was: for x in directory/*/py; do python $x; done However, since most source files in a Sugar activity tend to depend on GTK+ or Sugar, this approach is not as useful. This approach can be used for the model third of the model view controller style. Taylor, sugar-launch can be used to launch an activity in a testing environment, but scripted control of the launched activity is your next challenge. -- James Cameron <a href="http://quozl.linux.org.au/" target="_blank">http://quozl.linux.org.au/</a> </blockquote></div>
