Test automation has become a key competitive advantage that directly impacts product quality and development productivity. Building on its proven expertise in V2X technologies, SAESOL Tech has introduced S2X Tester 2.0, an OpenTAP®-based test automation platform.
S2X Tester 2.0 is a plugin-based platform that supports the entire testing workflow within a single environment—from Test Plan design and equipment control to test execution, result analysis, and report generation. Its greatest strength is its flexibility, enabling seamless application across a wide range of industries, including V2X, drones, defense, telecommunications, and embedded systems.
Now, let's take a closer look at the key features and newly introduced capabilities of S2X Tester 2.0.
S2X Tester 1.0 Achieved OmniAir OQTE Certification
1. Hierarchical Test Plan Structure
S2X Tester 2.0 introduces an enhanced Test Plan management system with a newly designed hierarchical structure consisting of Test Cases, Test Steps, and Child Steps. This structure enables users to organize test procedures in a logical sequence while designing even the most complex test scenarios with greater clarity and efficiency.
Within a single Test Case, multiple Test Steps can be defined, and each Test Step can contain multiple Child Steps. This hierarchical approach makes it easy to build sophisticated test workflows while maintaining a clear and intuitive structure.
For example, a "Security Authentication Test" Test Case can include Test Steps such as Certificate Request, Digital Signature Verification, and Message Transmission Validation, with each Test Step further divided into detailed Child Steps to represent individual testing actions.
This hierarchical architecture not only improves the visibility and organization of test scenarios but also simplifies test asset reuse and maintenance, providing greater efficiency for managing large-scale testing projects.
2. Reduce Repetitive Work, Maximize Reusability
S2X Tester 2.0 introduces Test Step reusability, allowing frequently used Test Steps to be created as shared assets and reused across multiple Test Cases. This enables faster development of test scenarios while ensuring greater consistency throughout the testing process.
By managing tests with reusable Test Steps, the same testing logic can be efficiently applied across multiple Test Cases, improving both test asset management and long-term maintainability.
This capability is particularly valuable for repetitive tasks such as authentication procedures and message verification. As projects grow in scale, organizations can significantly reduce test development time while improving operational efficiency through standardized and reusable test workflows.
3. A Platform Built for Scalability and Compatibility
S2X Tester 2.0 adopts OpenTAP®, a global open-source test automation framework led by Keysight, as its Core Engine for backend control.
OpenTAP® is a proven test automation framework widely used by global test and measurement companies, including Keysight, in real-world testing environments. It provides world-class stability and reliability for equipment control and test scheduling.
By delegating critical low-level control operations to the OpenTAP® engine, SAESOL Tech ensures high system integrity and reliability. Meanwhile, SAESOL Tech’s proprietary technologies focus on delivering differentiated capabilities in user experience (UI), project management, plugin architecture, and test operation workflows.
Most importantly, as S2X Tester 2.0 is built on the OpenTAP® ecosystem, it can seamlessly utilize or integrate various OpenTAP® Test Steps and Test Case assets developed for Keysight environments. This compatibility with existing OpenTAP®-based test assets significantly enhances test asset reusability and improves overall development productivity.
4. Simplified DUT and Equipment Management with Profiles
S2X Tester 2.0 enables profile-based management of DUT and Equipment configurations. Test environments can be saved as Profiles and easily loaded or reused whenever needed, allowing users to configure consistent test environments across various projects.
This capability reduces repetitive setup efforts and enables more efficient test operations.
5. Flexible DUT and Equipment Expansion with Plugin Architecture
S2X Tester 2.0 adopts a plugin-based architecture that enables flexible expansion of DUTs (Devices Under Test) and Equipment.
Even when new test instruments or testing environments are introduced, they can be easily integrated and utilized through plugins, allowing the platform to adapt quickly to diverse project requirements.
This extensible architecture also provides long-term flexibility in response to evolving test environments and the adoption of new equipment, enhancing the value of S2X Tester 2.0 as a future-ready test automation platform.
