// Automated CI/CD & Testing Strategy
Overview & My Role
Implementing user stories, fixing bugs, and maintaining a robust CI/CD pipeline for industrial motion firmware.
- >Developed and maintained GitHub Actions workflows for automated builds and deployments.
- >Authored IEC tests specifically for motion functionalities on real hardware.
- >Full-cycle feature implementation from story to production-ready firmware.
// System Summary
• Rack Setup: Physical PLCs mapped in a structured environment.
• VM Environment: VMs specialized by build & execute queues.
• Scope: Integrated end-to-end regression validation.
> Infrastructure
Git Versioning Repo
Central GitLab repository managing codebase history, branches, and Webhook pipeline integrations.
Static Analysis Engine
Automated code complexity audit and security vulnerability checking utilizing Coverity, Squore, and Klocwork.
FW Builder VM
Dedicated virtual builder nodes compiling firmware binaries dynamically for target RTOS platform.
Runner VMs (1, 2, 3)
Parallel virtual test executors connected to target setups to flash binaries and trigger test programs.
PLC Test Systems (1, 2, 3)
Physical industrial PLC systems (IEC 61131-3) mounted on dedicated racks to execute motion tests.
> Automation
A rapid developer feedback loop is essential during feature development. Integrating automated static code analysis ensures high code quality and early mitigation of cybersecurity vulnerabilities, while running automated regression tests on actual target hardware guarantees real-world performance and integration stability before release.
