Playwright Test

Instructions

Step 1: Read the Handbook FIRST

CRITICAL: Before generating any tests, read and apply ALL patterns from:

openmetadata-ui/src/main/resources/ui/playwright/PLAYWRIGHT_DEVELOPER_HANDBOOK.md

The handbook contains:

• Testing philosophy (user-centric, behavior-focused)
• Anti-flakiness patterns (the :visible selector chain pattern, etc.)
• Test timeout strategies (test.slow() vs test.setTimeout())
• Common test patterns (form submission, dropdowns, multi-role testing)
• Locator priority guidelines
• Support classes reference
• Domain tags
• Validation checklist

Apply ALL handbook principles before proceeding.

Step 2: Generate Test Using Handbook Template

Use the Test File Structure Template from the handbook. It includes:

• Proper imports (performAdminLogin, entity classes, utilities)
• test.describe with domain tags
• beforeAll/afterAll for entity lifecycle via API
• test.slow() for timeout handling
• test.step() for clear organization
• API response validation pattern

Step 3: Apply Common Test Patterns from Handbook

Reference the Common Test Patterns section for:

• Form submission with API validation
• Dropdown selection (with :visible chain pattern)
• Multi-role permission testing
• Data persistence verification
• Navigation patterns
• Search and filter patterns

Step 4: Run ESLint Check

Before returning the generated test, run the Playwright linter to catch anti-patterns automatically:

cd openmetadata-ui/src/main/resources/ui
yarn lint:playwright

Error-level rules (no-networkidle, no-page-pause, no-focused-test) will block CI. Fix any errors before finalizing. See the handbook's ESLint Enforcement section for the full rule reference.

Step 5: Validate Against Handbook Checklist

Before returning the generated test, verify ALL items from the handbook's Validation Checklist:

• ✅ Structure & Organization (test.step, domain tags, imports, beforeAll/afterAll)
• ✅ Anti-Flakiness (no waitForTimeout, no networkidle, no force: true, no positional selectors, no stored :visible locators)
• ✅ API & Network (waitForResponse before actions, status code validation)
• ✅ Waits & Assertions (waitForAllLoadersToDisappear, semantic locators, proper assertions)
• ✅ ESLint (yarn lint:playwright passes with zero errors)
• ✅ Coverage & Roles (multi-role tests, data persistence, error handling)

Key Reminders

All patterns, rules, and best practices are in the handbook.

Read and apply the handbook sections in order:

1. Anti-Flakiness Patterns (CRITICAL - #1 cause of flaky tests)
2. Test File Structure Template (for proper test structure)
3. Common Test Patterns (for specific scenarios)
4. ESLint Enforcement (run yarn lint:playwright — errors block CI)
5. Validation Checklist (before returning generated test)

Final Notes

• Generate production-ready tests that pass 10/10 times
• Follow ALL patterns from the handbook exactly
• No comments for obvious code (e.g., // Create entity before entity.create())
• Test independence - each test runs in any order
• Reference examples: playwright/e2e/Pages/DataContractInheritance.spec.ts, playwright/e2e/Features/Table.spec.ts

Generate tests that are production-ready, maintainable, and zero-flakiness by following the handbook patterns exactly.
