We’ve talked about having both a test-a-thon and a doc-a-thon to get tests and documentation in shape for the upcoming tutorials at KHQ in July.
One thing that would be interesting would be to have the tests generate images for the documentation (or at least using the testing framework to generate images or even movies for the documentation). Ken Martin has done some work that exposes portions of the Qt UI to ParaView inside virtual reality; we could probably use the same technique to grab images or movies of Qt XML “tests” for the documentation.
By making portions of the documentation contribute to test results, we could catch at least some places where the documentation becomes out-of-sync with the implementation. It would also reduce the manual effort required to keep figures up-to-date as the modelbuilder UI changes.
