Systematic test design using the Classification Tree Method
The Classification Tree Editor (CTE) is a graphical editor which provides a systematic and easy understandable way to create test cases in a graphical notation. It is used to transform a (functional) specification into a set of error sensitive and low redundant test case specifications.
The CTE can be used generally, in all test phases, in all programming languages, for every application in the IT, from embedded over mobile to web applications.
The following sections outline CTE’s core feature. Your comments and questions about the CTE are appreciated.

The idea of the Classification Tree Method
With the help of the Classification Tree Method it is easily possible to design tests for different areas in software development. The following two steps are necessary
Identify the test relevant aspects (classifications) and their corresponding values (classes).
Combine the different classes from all classifications in test cases.
Create test case specifications with the graphical editor
The Classification Tree Editor (CTE) is used to design classification trees and create test case specifications in an intuitive way.
Describing the tree elements, test relevant aspects and their recursive partitioning in equivalence classes to build the classification tree.
Setting the values on the elements of the tree and combining classes of the tree to specify inputs and expected results within a combination table leads to the creation of test cases.
The result will be a comprehensible test case specification: The description text of marked tree elements and its values are used to generate the test case specification.
The test case specifications can be exported to *.xml, *.xlsx, *.txt, *.svg, *.png, *.jpg.
Key features
Create error sensitive and low-redundant test cases
Create, import and export classification trees
Define dependency rules between test aspects
Automated generation of test case specifications
Automatic validation checks
Statistics data
Customizable auto-layout
In addition CTE provides features for more detailed test case specifications, for subdividing a tree in subtrees as well as an easy navigation through subtrees and elements and simplified handling by drag and drop and short keys.
Your benefits
A systematic and easy understandable way to create test cases in a graphical editor.
Partly automated generation of test case specifications.
Export of test data for further use by other tools, e.g. TESSY.
Available as integrated version into TESSY or as standalone version for Windows 7/8/10/11 (64bit)
