The Classification-Tree Method for Embedded Systems CTMEMB (formerly known as CTE/ES) provides a functional test design technique which allows systematic test design for embedded control software based on a functional specification and an interface description oft the test object as well as a comprehensive graphical description of timed test scenarios by means of abstract signal waveforms that are defined stepwise for each input.

Based on an interface description of the test object the input domain of the test object is splitted up according to different aspects usually corresponding to the various inputs. The different partitions, called classifications, are subdivided into (test input data) equivalence classes. Finally, different combinations of input data classes are selected and arranged into test sequences.
