Frappe CI Expert

Overview

This skill provides comprehensive guidance for setting up Continuous Integration (CI) testing for Frappe applications using GitHub Actions. It covers the complete CI setup process including database services, bench initialization, site creation, and test execution based on official Frappe and ERPNext patterns.

What This Skill Covers

Setting up CI tests for Frappe apps requires several components working together:

1. GitHub Actions Workflow - Define when and how tests run
2. Database Services - Configure MariaDB or PostgreSQL containers
3. Dependencies - Install system packages, Python packages, and Node.js
4. Bench Setup - Initialize bench and create test sites
5. Test Execution - Run server tests, UI tests, or parallel tests
6. Debugging - Access logs and troubleshoot CI failures

Quick Start

For a standard Frappe app with server tests:

1. Create .github/workflows/server-tests.yml based on references/workflow-templates.md
2. Add helper scripts from references/helper-scripts.md
3. Configure database services from references/database-services.md
4. Follow the setup steps in references/ci-setup-process.md

Reference Documentation

Workflow Templates

See references/workflow-templates.md for:

• Complete server tests workflow

• Patch migration tests workflow
• Customizing workflows for your app

Database Services

See references/database-services.md for:

• MariaDB service configuration
• PostgreSQL service configuration
• Database credentials and configuration
• Site config JSON templates

CI Setup Process

See references/ci-setup-process.md for:

• Step-by-step bench initialization
• Installing dependencies
• Creating and configuring test sites
• Process management (Procfile modifications)
• Starting bench services in CI

Helper Scripts

See references/helper-scripts.md for:

• install_dependencies.sh - System packages setup
• install.sh - Bench initialization and site creation
• Database setup scripts
• Best practices for helper scripts

Test Execution

See references/test-execution.md for:

• Running parallel tests for server
• Running UI tests with Cypress
• Test output and logging
• Code coverage setup

CI Patterns and Best Practices

See references/ci-patterns.md for:

• Caching strategies (pip, yarn, Cypress)
• Performance optimization
• Debugging CI failures
• Common pitfalls and solutions
• Multi-matrix testing strategies

Key Concepts

Services in GitHub Actions

Frappe apps typically require:

• Database: MariaDB 10.6+ or PostgreSQL 12+
• Redis: For caching and background jobs (optional for basic tests)
• SMTP: For email testing (smtp4dev)

These run as Docker containers in the GitHub Actions runner.

Test Site Configuration

CI tests use a dedicated test site (typically test_site) with:

• Specific database credentials
• Test-safe email configuration
• Monitoring and server scripts enabled
• Host entry in /etc/hosts for proper URL resolution

Bench in CI

The bench setup in CI differs from development:

• Installed via pip (not git clone)
• Uses --skip-assets flag for speed
• Disables watch/schedule processes
• Runs in background for tests

Common Use Cases

Setting Up Server Tests

Follow the complete example in references/workflow-templates.md which includes:

• Workflow triggers (PR, workflow_dispatch, schedule)
• MariaDB and PostgreSQL services
• Full setup steps
• Parallel test execution

Adding UI Tests (Cypress)

See references/workflow-templates.md for:

• Cypress binary caching
• Matrix strategy for parallel execution
• Setup wizard completion
• Headless browser configuration

Testing Database Migrations

Check references/workflow-templates.md for:

• Testing upgrades from older versions
• Restoring production backups
• Sequential migration testing

Custom App Testing

When setting up CI for your own app:

1. Start with the server tests template
2. Modify the app name and repository references
3. Add any app-specific dependencies
4. Adjust test commands if needed
5. See references/ci-patterns.md for details

Environment Details

Standard Paths

• Bench directory: ~/frappe-bench or /home/runner/frappe-bench
• Apps directory: ~/frappe-bench/apps/
• Sites directory: ~/frappe-bench/sites/
• Logs: ~/frappe-bench/logs/

Standard Configuration

• Test site name: test_site
• Database name: test_frappe
• Database user: test_frappe
• Database password: test_frappe
• Root password: travis
• Admin password: admin

Python and Node Versions

Based on Frappe requirements:

• Python: 3.10+ (typically 3.10 or 3.11)
• Node.js: 24 (use setup-node@v3 or higher with check-latest)

Debugging CI Failures

When tests fail in CI:

1. Check the logs - Workflow outputs bench logs and error logs
2. Reproduce locally - Use the same commands from the workflow
3. Enable tmate - Add debug-gha label for interactive debugging
4. Check services - Ensure database services are healthy
5. Review build output - Asset build failures are common issues

See references/ci-patterns.md for detailed troubleshooting.

Integration with Frappe Apps

For Apps in the Frappe Ecosystem

If building an app to work with ERPNext or other Frappe apps:

• Install the dependent app in your CI workflow
• Use bench get-app to fetch dependencies
• Install apps in the correct order
• Test against multiple versions if needed

For Standalone Apps

If your app doesn't depend on other Frappe apps:

• Test against the base Frappe framework only
• Keep the setup minimal
• Focus on your app's specific tests
