Abstract: Aspects described herein may relate to an application code testing computing device, which may be configured to run an application code testing plug-in and a framework core. The application code testing computing device may receive a set of codeless instructions (for example a Gherkin format) for testing one or more applications associated with one of a plurality of technology types, where each of the technology types is associated with a library component supported by the framework core. The application code testing computing device determines the associated technology type from the syntax of one or more steps contained in the set of instructions. Moreover, the application code testing computing device may detect a change of the technology type when executing test script from the syntax of currently processed steps.
