Abstract

Generation of test models from Behavior Driven Development scenarios based on Behavior Driven Development step definitions and similarity analysis using Neuro Linguistic Programming and machine learning mechanisms The present invention pertains to a method for automated verification of a software program in a Behavior-Driven Development (BDD) environment and a data processing system configured to execute such a method. Individual test steps of BDD test scenarios are first matched and then assigned to existing test step definitions from a BDD framework. If a one-to- one matching is not possible, natural language processing (NLP) is used to decide if an assignment is possible with a certain matching probability. The assigned test step definitions are used to generate graphical test models for the test scenarios, e.g. UML diagrams. Finally, executable test scripts are generated to test the software program. The present invention relates particularly to Behavior-Driven Development (BDD) and combines traditional BDD advantages with Model Based Testing (MBT) for improved convenience and automatization in case of complex software packages. The automated step matching allows an efficient mapping of BDD step phrases to a test automation framework and supports the structured development of the necessary framework code. The graphical test models add an additional abstraction layer and provide the opportunity to check BDD scenarios for consistency and completeness.

Description

technical field [0001] The present invention relates to a computer-implemented method for automatic verification of software programs in a behavior-driven development environment. The invention further relates to a device comprising a processor configured to perform such a method. In particular, the present invention relates to Behavior Driven Development (BDD). Background technique [0002] In recent years, BDD has emerged as an agile software development methodology for the specification and execution of automated acceptance tests for software programs. BDD was introduced by Dan North in 2006 to simplify Test Driven Development (TDD), see for example "Drei Methoden, ein Ziel: Testautomatisierung mit BDD, MBT und KDT imVergleich", Brandel et al., Softwaretechnik-Trends, 35(3), 2015 . TDD is a software development methodology that essentially stipulates that for each unit of software, the software developer must first define a specific set of tests for the unit, then impl...
