The Classification Tree Method (CTM)
It is an approach to testing which uses a descriptive tree-like notation. It is especially suited for automation since:
[a] it decomposes the test case design process into several steps that can be automated individually allowing the tool [Classification Tree Editor CTE] to appropriately guide the user and [b] it offers a graphical notation well suited for visualisation in a modern Graphical User Interface (GUI).
Test cases are built to exercise a combination of classes from different classifications [across a number of aspects].
The technique is easy to apply and is easily scaleable with the use of the tool, Some practice at identifying classes within classifications and the production of the tree is required but once the basics are understood the technique is very simple.

Technique steps:
- Identify the input aspects and classifications
- Produce the Classification Tree
- Select the input combinations to test based on risk
- Prioritise and execute the tests based on risk
