Grafiker, a Guildhall tools applet

It's generally true that it's a good idea to write tests that target the code you've designed and implemented. But those tests themselves can be subject to an amount of bias. Random tests are one way to find bugs without the bias. This is especially true of graphics engines. Grafiker throws a lot of different kinds of graphics at the screen, random shapes, random styles, random colors, random transforms, and random clipping. If something has gone south it tends to show up pretty quickly so it can be tracked down. It also offers a pretty good measure of how well the system is performing.

Here are a few sample screens.

Next Steps

• None planned. New Grafiker features are ruled by serendipity.
