ATLAS
Test Case Generator
The Challenges
- ADAS & autonomous driving systems require level of safety critical embedded software testing never seen before by Tier1 & Tier 2 in the automotive industry (ISO 26262)
- Aircraft systems require level of safety critical embedded software testing never seen before by Tier1 & Tier 2 in the aerospace industry (DO-178C, MIL-HDBK-516C)
- Legacy Embedded systems & software: the requirements were not defined in a standard way and sometimes may be hidden in various documents such specification, user guide, instructions. Most of the time the ‘experts’ on these systems left the workforce. Identifying requirements may be a truly hassle
- New embedded systems & software: their complexity and number of functionalities grow: the number of requirements grow exponentially causing more testing work to generate the artifacts such as test cases, scripts, data reviews
Our Solution
In this context, CS has developed ATLAS which is a software suite that:
- parses multiple type of documents.
- identifies hand-written english requirements
- parses these requirements and convert them in test cases in compliance with usual standards such as DO-178C and ISO-26262
For example, from the requirement: “Pressing the safety button 3 times will trigger a GCS pairing request”
The following test cases (positive and negative) are generated:
Test Case 1: Verify that the GCS pairing request is triggered when the safety button is pressed 3 times.
Test Case 2: Verify that the GCS pairing request is triggered when the safety button is pressed more than 3 times.
Test Case 3: Verify that the GCS pairing request is NOT triggered when the safety button is pressed less than 3 times.
Test Case 4: Verify that the GCS pairing request is NOT triggered when the safety button is pressed 3 times.
Innovation Component
- ATLAS is based on open source and proprietary source code. A part of the source code use machine-learning techniques.
- ATLAS was developed using real use cases from Aerospace OEMs.
- Main interface is based on Jupyter NoteBook that can be faciliate the integration to third-party platforms or infrastructures.
- ATLAS was architected to be installed on single machines or on servers (including secured ITAR infrastuctures).
Benefits to Customers
- Accelerate system and software test process by 20%
- Time savings on client teams to identify the real requirements
- Mechanize the generation and standardization of test cases artefacts in compliance with DO-178C from a large number of requirements (millions)
- Acceleration of the testing to reduce time-to-market
Why CS ?
- 17 years hands-on experience in V&V.
- CS is recognized for its expertise in embedded software and systems in the Automotive, Aerospace & Defense industries.
