Test PR Skill

Overview

Test a pull request to ensure code quality, functionality, and compatibility before merging.

Inputs

• PR number or URL
• Optional: specific test patterns to run

Safety

• Never modify code in this skill
• Only read and test
• Generate artifacts in .local/ directory
• Do not push changes

Execution Contract

1. Fetch PR metadata
2. Checkout PR branch in isolated worktree
3. Install dependencies
4. Run test suite
5. Run pre-commit hooks
6. Generate structured test results
7. Output recommendation

Steps

1. Initialize PR Testing

# Get PR metadata
PR_NUMBER=$1
gh pr view $PR_NUMBER --json number,title,author,headRefName,baseRefName > .local/pr-meta.json

# Create isolated worktree
git worktree add .worktrees/pr-$PR_NUMBER origin/main
cd .worktrees/pr-$PR_NUMBER

# Fetch PR branch
git fetch origin pull/$PR_NUMBER/head:pr-$PR_NUMBER
git checkout pr-$PR_NUMBER

2. Install Dependencies

# Install with frozen lockfile
uv sync --frozen

# Verify installation
uv run python -c "import bindu; print(bindu.__version__)"

3. Run Test Suite

# Run all tests with coverage
uv run pytest --cov=bindu --cov-report=json --json-report --json-report-file=.local/test-results.json

# Extract coverage percentage
COVERAGE=$(jq -r '.totals.percent_covered' coverage.json)
echo "Coverage: $COVERAGE%"

4. Run Pre-Commit Hooks

# Run all hooks
uv run pre-commit run --all-files > .local/precommit-results.txt 2>&1

# Check exit code
if [ $? -eq 0 ]; then
    echo "✅ All pre-commit hooks passed"
else
    echo "❌ Some pre-commit hooks failed"
fi

5. Check for Common Issues

# Check for print statements (should use logger)
grep -r "print(" bindu/ --include="*.py" | grep -v "# noqa" || echo "✅ No print statements"

# Check for TODO comments
grep -r "TODO\|FIXME\|XXX" bindu/ --include="*.py" || echo "✅ No TODO comments"
