Uwe Liebold of AMD is here to talk about testing frameworks that they use in their Smalltalk applications:
The CEI application is part of their APM (Automated Precision Manufacturing) approach. The APM powered fabs are controlled by software/hardware that Uwe calls their "central nervous system". The CEI baseline began with Fab 25 in Austin, Texas in the early 90's. It's been extended, enhanced over time. Currently, they are using VisualWorks 7.2. They have:
- ~3000 classes
- ~45,000 methods
- 27 MB runtime image
They have gotten more and more interested in testing as time has gone by - they simply cannot afford downtime in a 24x7 manufacturing system. At the same time, they have continuously changing requirements, so implementation and integration are never done. They started to get more serious about unit testing after they migrated up from VW 5i.4.
They've put testing on an equal footing with development - they now run all their tests after every integration, and they use SUnit both in development and in deployment (using RuntimeTestRunner, a tool that logs results rather than reporting to a GUI). They've introduced a concept called Matric Tests, which is based on hardware test scenarios. It's a 4 step process:
- Set parameter(s)
- Run component
- Read result
- Validate result
He's wrapping up with a demo - the TestMatrix stuff is kicked off the same way that normal SUnits are - using the browser extensions, straight from the RB.
