Playwright E2e

Playwright E2E Test Workflow

Three-agent workflow for generating end-to-end tests for the Opik application:

1. Planner -> Explores the Opik UI, generates a markdown test plan with fixture/page-object references
2. Generator -> Transforms the plan into executable Playwright tests following Opik conventions
3. Healer -> Automatically fixes failing tests with Opik-specific debugging knowledge

When to Use

Use when developer requests E2E test generation or repair:

• "Generate an E2E test for the new dashboard"
• "Create automated test for the upload flow"
• "Add happy path test for experiment creation"
• "Fix the failing prompts test"

Prerequisites

# Opik must be running locally
# Frontend at http://localhost:5173
# Backend healthy

# Playwright environment
cd tests_end_to_end/typescript-tests
npm install
npx playwright install chromium

Safety: Verify Local Config

Before running any tests or SDK operations, check ~/.opik.config. The Python Opik SDK (used by the Flask test helper service) reads this file. If it points to a cloud environment, the workflow will accidentally create real data there.

cat ~/.opik.config

If url_override points to anything other than http://localhost:5173/api, back up and fix it:

cp ~/.opik.config ~/.opik.config.bak 2>/dev/null || true
cat > ~/.opik.config << 'EOF'
[opik]
url_override = http://localhost:5173/api
workspace = default
EOF

After the workflow is complete, remind the user to restore their config: cp ~/.opik.config.bak ~/.opik.config

Knowledge Base

These context files provide the domain knowledge agents need to produce accurate tests:

• opik-app-context.md - Opik entities, URL structure, dual SDK/UI pattern, Flask bridge architecture
• test-conventions.md - Import patterns, naming, tags, annotations, locator preferences, waiting strategies
• page-object-catalog.md - All page objects with method signatures and constructor info
• fixture-catalog.md - Fixture hierarchy, types, cleanup behavior, import paths

Workflow Phases

Phase 1: Planning

Agent: agents/playwright-test-planner.md Input: Running Opik app + feature description Output: tests_end_to_end/typescript-tests/specs/{feature-name}.md

Uses seed test: tests/seed-for-planner.spec.ts

Phase 2: Generation

Agent: agents/playwright-test-generator.md Input: Markdown test plan from specs/ Output: tests_end_to_end/typescript-tests/tests/{feature-area}/{test-name}.spec.ts

Uses existing fixtures and page objects. References test-conventions.md for all coding standards.

Phase 3: Healing

Agent: agents/playwright-test-healer.md Input: Failing test + error info Output: Passing test or test.fixme() if the feature is genuinely broken
