The Classification Tree Method is a method for test design, as it is used in different areas of software development (e.g. embedded systems …). Classification Trees in terms of the Classification Tree Method must not be confused with decision trees.
The classification tree method consists of two mayor steps: (1) Identification of test relevant aspects (so called classifications) and their corresponding values (called classes) as well as (2) Combination of different classes from all classifications into test cases.
The identification of test relevant aspects usually follows the (functional) specification (e.g. requirements, uses cases …) of the system under test. These aspects form the input and output data space of the test object.
The second step of test design then follows the principles of combinatorial test design.
