There are tests whose baselines cannot be written. When early models of a production car first roll off the line
they are subjected to special usability tests. These are conducted by drivers expert in the specifications of the car and
the expectations of users. Armed with enough monitoring gadgetry to sink a boat, they drive the car along lanes and
motorways, through mud, rain, and snow. Their objective is to fractionally improve the overall handling of the car.
Their results are fed back to the powertrain, steering, suspension, and braking specialists of the production line. Their
baseline is essentially their experience of cars and their expectations.

about how to walk: you could ask, but the centipede would fall over. In practice centipedes
walk and (games) programmers program. While games programmers may appear to work in
an unstructured manner, in reality they create and tear down structures as they need them.
Thus if there??™s a need for a video insert, be sure that one will be scripted and built in. The
tester must create what baselines are required if only by writing them himself. Such baselines
can be minimal and make sense to the testers alone. If you don??™t have baselines you can use a
notation like the ones discussed in section A.
