Tasks

• Gather context and read codebase (C fan daemon project)
• Understand existing functionality
• Write tests in test.c:
  • curve interpolation (curve_get_value: below min, above max, exact point, between points, single-point curve)
  • curve create/destroy lifecycle
  • sensor create/destroy (including offset)
  • fan create/destroy (path construction verified)
  • zone create/attach/destroy
  • zone attachment limit enforcement (MAX_ZONE_SIZE)
  • config loading: valid YAML, missing file, empty zones, multiple zones
• Update Makefile with a test target (make test builds and runs test_runner)
• Commit and push changes

GitHub Actions Workflow

Due to GitHub App permission restrictions, I cannot create files in .github/workflows/ directly. Please create .github/workflows/test.yml manually with the following content:

name: Tests

on:
  push:
    branches: ["**"]
  pull_request:
    branches: ["**"]

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4

      - name: Install dependencies
        run: sudo apt-get install -y libyaml-dev

      - name: Build and run tests
        run: make test

Summary

test.c — Replaced the stub with a full test suite (no external framework required):

Test group	Tests
Curve	create/destroy, below min, above max, exact point, linear interpolation, single-point
Sensor	create/destroy, with offset
Fan	create/destroy, path construction
Zone	create/destroy, attach sensor, attach fan, attachment limit
Config	load valid YAML, missing file, empty zones, multiple zones

Makefile — Added:

test:
    $(CC) $(CFLAGS) fan.c sensor.c zone.c curve.c config.c test.c -o test_runner
    ./test_runner

Run locally with make test.
