    Open Test Framework

    Leading development environment for creating, visualizing and maintaining a new generation of testers. Without programming knowledge, ISO 13209 (OTX) compliant test sequences can be graphically created, tested and approved.

    Technical paper "OTX in practice":

    Open Test Player

    Generic tester for easy distribution and execution of ISO 13209 (OTX) compliant test sequences.

    Open Test Runtime API

    Platform-independent runtime environment for OTX sequences according to ISO 13209. The programming interface for DotNet, Java and DCOM can be used in own applications under Windows, Linux and Linux Embedded.

    OTX Tool Chain at a Glance


    For diagnostic communication, the OTX Runtime operates on a standardized diagnostic runtime system (MVCI according to ISO 22900, ODX). There are implementations for most known runtime systems (DSA, VW, Siemens, RA-Consulting). However, proprietary systems can also be connected.

    With the development environment, OTX sequences are developed and distributed within a PTX file. In addition, a graphical user interface can be created with the Player Editor and distibuted as a PPX file.

    PTX files are ZIP archives. They contain all OTX documents and project settings. PTX files can be signed or encrypted.

    The OTX Runtime API is an easy to use programming interface in Java and DotNet for executing OTX projects (PTX). The API is available for Windows and Linux.

    The OTX Runtime API is coupled to the runtime environment via remote interface. Thus, the OTX Runtime API and also the PLayer are Remote capable.

    The OTX Runtime is multi-instance capable and platform independent. It runs under WIndows, Linux, Linux Embedded and also inside the vehicle.

    PPX files contain complete testers (players) including all needed PTX projects. They can be executed with the Open Test Player.

    The player is practically a generic interface for OTX sequences and thus a complete tester. It is completely based on the OTX Runtime API. It currently runs only under Windows. Implementations for Linux, iOS and Android are planned.
