Playwright E2E Test Guide

Quick Start

pnpm test                 # Run all tests (fresh containers)
pnpm run test:local       # Run against http://localhost:5678

Test Commands

# By Mode
pnpm run test:standard    # Basic n8n
pnpm run test:postgres    # PostgreSQL
pnpm run test:queue       # Queue mode
pnpm run test:multi-main  # HA setup

# Development
pnpm test --grep "workflow"           # Pattern match

Test Tags

test('basic test', ...)                              // All modes, fully parallel
test('postgres only @mode:postgres', ...)            // Mode-specific
test('needs clean db @db:reset', ...)                // Sequential per worker
test('chaos test @mode:multi-main @chaostest', ...) // Isolated per worker

Tips

• test:* commands use fresh containers (for testing)
• VS Code: Set N8N_BASE_URL in Playwright settings to run tests directly from VS Code
• Pass custom env vars via N8N_TEST_ENV='{"KEY":"value"}'

Project Layout

• composables: Multi-page interactions (e.g., WorkflowComposer.executeWorkflowAndWaitForNotification())
• config: Test setup and configuration (constants, test users, etc.)
• fixtures: Custom test fixtures extending Playwright's base test
• pages: Page Object Models for UI interactions
• services: API helpers for E2E controller, REST calls, etc.
• utils: Utility functions (string manipulation, helpers, etc.)
• workflows: Test workflow JSON files for import/reuse
