The Challenge

In-house tools are double-edge swords for many companies. On one side, you have a tool especially designed for you and your company’s needs; on the other, they cultivate dependency on an easily obsoleted product. An aeronautics and aerospace manufacturer found themselves facing a similar issue with an in-house tool using scripts and requiring manual testing. Manual processes add to the stress and strain of workload for employees and are less efficient. This company sought out a solution that could handle their certification process and integration testing for regulatory compliance.

The Solution

HCL OneTest Embedded offered qualification kits for DO-178C and other standards, and this kit was very important for this aeronautic manufacturer to ensure regulatory compliance with standards. During development, complexity analysis was incorporated using static analysis capabilities in HCL OneTest Embedded. Additionally, HCL OneTest Embedded tests both low-level requirements and high-level requirements, which was critical to meet the DO-178C standard.

The Results

HCL OneTest Embedded was able to successfully demonstrate automation across all the customer’s applications and interfaces and integrate the build chain to provide test and runtime analysis results. Benefits included environment integration using the Target Deployment Port and testing across multiple different compilation units. HCL OneTest Embedded tested both low-level requirements and high-level requirements, and this customer achieved 100% coverage of their low-level requirements – meeting the DO-178C standard. Testing also covered functions in isolation and calls to external functions, both stubbed and real. High-level requirements were able to be tested across multiple source files and projects, and verification artifacts can be stored in configuration management for audit history. They were also able to achieve instrumentation coverage without code behavior modification. The integration of HCL OneTest Embedded results in automated evaluation of expected results, removing manual processes, was a key result. This aeronautics and aerospace company’s adoption of HCL OneTest Embedded results in a truly innovative future. Showcasing how with HCL OneTest Embedded, the sky is the limit.
