Quick reference for common development workflows in the WordPress ActivityPub plugin.

Quick Reference

Environment Management

npm run env-start    # Start WordPress at http://localhost:8888.
npm run env-stop     # Stop WordPress environment.

Testing Commands

npm run env-test                      # Run all PHP tests.
npm run env-test -- --filter=pattern  # Run tests matching pattern.
npm run env-test -- path/to/test.php  # Run specific test file.
npm run env-test -- --group=name      # Run tests with @group annotation.
npm run test:e2e                      # Run Playwright E2E tests.
npm run test:e2e:debug                # Debug E2E tests.

Code Quality

composer lint         # Check PHP coding standards.
composer lint:fix     # Auto-fix PHP issues.
npm run lint:js       # Check JavaScript.
npm run lint:css      # Check CSS styles.
npm run format        # Format all code (wp-scripts).

Building Assets

npm run build         # Build for production (formatted and minified).
npm run dev           # Start development watch mode.

Code Coverage

npm run env-start -- --xdebug=coverage    # Start with coverage support.
npm run env-test -- --coverage-text       # Generate text coverage report.
npm run env-test -- --coverage-html ./coverage  # Generate HTML report.

Comprehensive Documentation

See docs/development-environment.md for detailed setup instructions.

See tests/README.md for comprehensive testing guidance.

See docs/code-linting.md for linting configuration and standards.

Pre-commit Hooks

The repository uses automated pre-commit hooks (.githooks/pre-commit) that run automatically on git commit:

1. Sort PHP imports - Automatically organizes use statements.
2. Check unused imports - Prevents unused use statements.
3. Validate test patterns - Blocks remove_all_filters('pre_http_request').
4. Run PHPCS auto-fix - Applies coding standards automatically.
5. Format JavaScript - Runs wp-scripts formatter.

IMPORTANT: Hooks modify staged files automatically. Always review changes before committing. If hooks make changes, you'll need to stage them and commit again.

Setup: Hooks are installed by npm run prepare (runs automatically after npm install).

Common Development Workflows

Initial Setup

git clone git@github.com:Automattic/wordpress-activitypub.git
cd wordpress-activitypub
npm install           # Also runs 'npm run prepare' to install hooks.
composer install
npm run env-start     # WordPress at http://localhost:8888.

Making Changes Workflow

# 1. Make code changes.

# 2. Run relevant tests.
npm run env-test -- --filter=FeatureName

# 3. Check code quality (optional - pre-commit hook does this).
composer lint
npm run lint:js

# 4. Commit (pre-commit hook runs automatically).
git add .
git commit -m "Description"
# Hook may modify files - review and stage again if needed.

Before Creating PR

# Run full test suite.
npm run env-test

# Build assets.
npm run build

# Final lint check.
composer lint
npm run lint:js

Debugging Failing Tests

# Run with verbose output.
npm run env-test -- --verbose --filter=test_name

# Run single test file to isolate issue.
npm run env-test -- tests/phpunit/tests/path/to/test.php

# Check test groups.
npm run env-test -- --list-groups
npm run env-test -- --group=specific_group

Fresh Environment

npm run env-stop
npm run env-start
# wp-env automatically sets up WordPress with debug mode and test users.
