Connected Systems & HIL Validation Lab
Reproducible Python/pytest verification harness and hardware-in-the-loop roadmap for Wi-Fi sensor nodes and device APIs.
- Role
- I built the deterministic device simulator, payload contract validator, boundary/recovery test suite, defect reports and ESP32 HIL fixture specification.
- System
- Python, pytest, GitHub Actions CI, JSON payload contract checks, induced ADC/network fault injection and serial/MQTT hardware-in-the-loop test plan.
- Constraint
- Isolate intermittent failures across the sensor, firmware state machine and cloud API boundary before deploying devices in the field.
- Outcome
- Automated test suite running in CI and a repeatable methodology for connected hardware validation and remote property telemetry nodes.
