Summary

Closes #88
Depends on #89 (framework extension)

Adds initial board qualification tests for user-accessible pins on the edge connector and crocodile clip pads. These tests verify basic GPIO/ADC functionality of each pin.

Note: Full pin testing requires a physical test bench (jig). Current tests cover basic ADC reads and digital pull-up reads. More comprehensive loopback/continuity tests will be added once the test bench hardware is designed.

Scenario: tests/scenarios/board_pins.yaml

Analog pin tests (ADC read)

Test Pin STM32WB55
P0 analog read P0 PC4
P1 analog read P1 PA5
P2 analog read P2 PC5
P3 analog read P3 PA2
P4 analog read P4 PA4
P10 analog read P10 PA6

Digital pin tests (pull-up read)

Test Pin STM32WB55
P6 digital pull-up P6 PC3
P7 digital pull-up P7 PA9
P8 digital pull-up P8 PA15
P9 digital pull-up P9 PC2
P12 digital pull-up P12 PC6
P16 digital pull-up P16 PE4

How to test

# Mock tests (no regression)
pytest tests/ -k mock

# Collect pin board tests
pytest tests/ -k board_pins --collect-only

# Run on hardware (requires STeaMi board)
pytest tests/ --port /dev/ttyACM0 -k board_pins -s -v

Test results

$ pytest tests/ -k mock -q
41 passed, 95 deselected

$ pytest tests/ -k board_pins --collect-only -q
12 tests collected (6 analog + 6 digital)

$ pytest tests/ -k board_pins -q  # (sans --port)
12 skipped  # correctly skipped without hardware

$ pytest tests/ --port /dev/ttyACM0 -k board_pins -s -v

Hardware test results will be added after board validation on test bench.

Test plan

  • ruff check tests/ — passed
  • pytest tests/ -k mock — 41 passed (no regression)
  • 12 pin board tests correctly collected and skipped without --port
  • Hardware validation on STeaMi board with test bench (pending)

Pull request overview

Adds an initial board-level qualification scenario to exercise user-accessible pins on the STeaMi edge connector/croc pads using the new type: board scenario support (from #89).

Changes:

  • Introduces tests/scenarios/board_pins.yaml as a type: board scenario.
  • Adds 6 analog (ADC) smoke tests and 6 digital pull-up read tests for user pins.

💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

Corrections suite à la review Copilot (f3fbfc9) :

  • Commentaire header reformulé : précise que ce sont des smoke tests (configuration + readback), pas des tests de continuité électrique. Mentionne explicitement que la continuité nécessite un banc d'essai avec des tensions connues.
  • Tests ADC simplifiés : adc.read_u16() suivi de result = True au lieu du tautologique 0 <= raw <= 65535. Le test vérifie que l'ADC peut être configuré et lu sans erreur.
