I reached a significant milestone today: the first real test was run.
I completed the integration of the W3C HTML validator (with HTML5 support) into the worker HTML task driver, an overly technical way of saying that HTML validation tests are now performing actual HTML validation and reporting the results back to the core application.
The above illustration is a screenshot from a database administration tool showing the raw data for the test tasks for a completed test job run on the integration environment.
The column on the right shows the collection of HTML validator error messages formatted as a JSON document.
A second illustration shows the JSON output of the core application running in the integration environment complete with test results.
The backend distributed test system is now carrying out real tests!
I can now focus on building the frontend (which will eventually be at simplytestable.com) and see where that leads in time for the internal prototype milestone listed on the roadmap as being next Wednesday.
