Understanding and utilizing Open Test Sequence Exchange (OTX) can significantly enhance the efficiency and quality of your testing processes, especially in the automotive industry. In this article, we delve into the intricacies of OTX, exploring its architecture, components, and functionalities to help you make the most out of this powerful tool.
OTX System Architecture Overview
OTX is a standardized platform and format designed for describing and executing test sequences. It is based on the ISO 13209 standard and aims to provide an executable test sequence description format independent of the tester. This architecture allows for the exchange of test knowledge across departments, tools, and processes, ensuring that technical expertise stored in sequences does not get lost over time.
OTX architecture is characterized by its verifiable quality, platform independence, and ability to connect with different standards, making it a coordinated and integrated solution.
Components of OTX System Architecture
The OTX system architecture is primarily composed of the following core components:
| Component | Description |
|---|---|
| OTX Core (Core) | Contains all general logic activities, such as process calls, assignments, branches, loops, parallel execution activities, and error handling. It is the core of the OTX architecture, providing the basic building blocks for test sequences. |
| OTX Extension Libraries | Extend the independent-running core with specific functionalities. These include various extensions, such as HMI (Human-Machine Interface), Quantities (Physical Unit Calculation), EventHandling (Event Processing), and Measurement (Measurement and Control Tasks). These extension libraries provide rich functionalities, enabling test sequences to describe more complex test scenarios. |
| Mapping Layer | Allows for the integration of user interfaces, environmental data, state information, or any device driver through the mapping layer. This enables the same OTX sequence to run on different test benches, simply by exchanging an XML file. |
| Tool Support | Includes tools for creating, editing, and executing OTX test sequences, such as OTXstudio. These tools provide a graphical user interface, making it easier for testers to create and manage test sequences. |
Functional Characteristics of OTX System Architecture
OTX system architecture boasts several functional characteristics:
- Standardization: OTX architecture is standardized, ensuring consistency and compatibility across different systems and tools.
- Interoperability: It allows for the exchange of test sequences between different systems and tools, facilitating collaboration and knowledge sharing.
- Scalability: OTX architecture can be easily scaled to accommodate the growing complexity of test sequences and requirements.
- Reusability: Test sequences created using OTX can be reused across different projects and test benches, saving time and effort.
- Extensibility: The architecture supports the addition of new functionalities and extensions, making it adaptable to evolving testing needs.
By leveraging the power of OTX, you can streamline your testing processes, improve the quality of your products, and enhance your overall efficiency.
