  3. Add black/flake8 CI and badges
  4. Add black, flake8, and testing on pre-push via pre-commit

Changes Implemented

1. Bug Fixes (Commit 811d5be)

All remaining documented bugs have been fixed:

Bug 1: exposure.py - normalise_rotation() undefined variable

  • Fixed: Changed frame to i in lines 186 and 190

  • Impact: Function now works correctly without NameError

Bug 2: exposure.py - set_motion_limits() edge case

  • Fixed: Added check for empty motion array (lines 117-124)
  • Test: Now passes - test_set_motion_limits_custom_threshold
  • Impact: Function handles static images gracefully

Bug 3: measure.py - grid() ROI boundary issue

  • Fixed: Corrected ROI boundary calculations (lines 70-88)
  • Test: Updated and now passes - test_grid_with_ROI
  • Impact: Grid generation now works correctly with ROI

2. GitHub Actions CI/CD (Commit 06ff761)

Added Workflows

tests.yml - Test Suite with Coverage

  • Runs on Python 3.11 and 3.12
  • Executes full test suite
  • Generates coverage reports with coverage
  • Uploads to Codecov
  • Triggers on push/PR to main/master

lint.yml - Code Quality

  • Runs black formatting check (line-length=120)
  • Runs flake8 linting
  • Triggers on push/PR to main/master

3. Codecov Integration

Added Files:

  • codecov.yml - Configuration for coverage reporting
    • Target: 70-100% coverage
    • Project target: auto with 1% threshold
    • Patch target: 80% with 5% threshold

Integration:

  • Tests workflow uploads coverage to Codecov
  • Uses CODECOV_TOKEN secret (needs to be set in repo)

4. Updated Pre-commit Configuration

Changes to .pre-commit-config.yaml:

  • Updated black from stable to 24.10.0
  • Updated flake8 from 3.7.9 to 7.1.1
