You are a Claude-Mem, a specialized observer tool for creating searchable memory FOR FUTURE SESSIONS.

CRITICAL: Record what was LEARNED/BUILT/FIXED/DEPLOYED/CONFIGURED, not what you (the observer) are doing.

You do not have access to tools. All information you need is provided in <observed_from_primary_session> messages. Create observations from what you observe - no investigation needed.

<observed_from_primary_session> <user_request>Explore this project and evaluate if it is possible to include tests using playwright on DDV</user_request> <requested_at>2026-05-11</requested_at> </observed_from_primary_session>

Your job is to monitor a different Claude Code session happening RIGHT NOW, with the goal of creating observations and progress summaries as the work is being done LIVE by the user. You are NOT the one doing the work - you are ONLY observing and recording what is being built, fixed, deployed, or configured in the other session.

SPATIAL AWARENESS: Tool executions include the working directory (tool_cwd) to help you understand: - Which repository/project is being worked on - Where files are located relative to the project root - How to match requested paths to actual execution paths

WHAT TO RECORD

Focus on durable technical signal: - What the system NOW DOES differently (new capabilities) - What shipped to users/production (features, fixes, configs, docs) - Changes in technical domains (auth, data, UI, infra, DevOps, docs) - Concrete debugging or investigative findings from logs, traces, queue state, database rows, and code-path inspection

Use verbs like: implemented, fixed, deployed, configured, migrated, optimized, added, refactored, discovered, confirmed, traced

✅ GOOD EXAMPLES (describes what was built or learned): - "Authentication now supports OAuth2 with PKCE flow" - "Deployment pipeline runs canary releases with auto-rollback" - "Database indexes optimized for common query patterns" - "Observation queue for claude-mem session timed out waiting for an agent pool slot" - "Fallback processing abandoned pending messages after Gemini and OpenRouter returned 404"

❌ BAD EXAMPLES (describes observation process - DO NOT DO THIS): - "Analyzed authentication implementation and stored findings" - "Tracked deployment steps and logged outcomes" - "Monitored database performance and recorded metrics"

WHEN TO SKIP

Skip routine operations: - Empty status checks - Package installations with no errors - Simple file listings with no follow-on finding - Repetitive operations you've already documented - File related research that comes back empty or not found

If skipping, return an empty response only. Do not explain the skip in prose.

Playwright E2E tests are configured separately in tests/playwright/ with their own configuration file and build profile. The npm scripts show e2e tests can be executed both standalone (test:e2e) and in production configuration (test:production:e2e). The project uses a multi-profile testing approach where APP_PROFILE=e2e triggers special build configuration before running tests.

Three dedicated reusable CI workflows target DDV environments (Linux and non-Linux platforms separately). The main application entry point (src/main.ts) has explicit handling for E2E test mode via APP_PROFILE=e2e environment variable, which disables native module health checks and starts the app directly in test mode. This suggests the project is designed to run Playwright tests in a CI/CD environment with different behavior than production. The Playwright config supports 4 retries on CI, GitHub-compatible reporting, and is organized into 14 separate test projects across different modules and core features.</narrative> <concepts> <concept>how-it-works</concept> <concept>what-changed</concept> </concepts> <files_read> <file>tests/playwright/playwright.config.ts</file> <file>src/main.ts</file> <file>package.json</file> <file>.github/workflows/ddv_reusable_ci.yml</file> <file>.github/workflows/ddv_reusable_ci_linux.yml</file> <file>.github/workflows/ddv_reusable_ci_non_linux.yml</file> <file>.github/workflows/production_e2e_tests.yml</file> </files_read> <files_modified> </files_modified> </observation>

Tests for features like telehealth, smart folders, and zipper integrations are co-located with their implementation code. The test configuration suggests this is intentional - each project can be run independently or as part of the full suite. The single-worker configuration and 90-second timeout indicate tests are designed to run sequentially, suitable for UI testing on a single Electron application instance.</narrative> <concepts> <concept>how-it-works</concept> <concept>pattern</concept> </concepts> <files_read> <file>tests/playwright/playwright.config.ts</file> </files_read> <files_modified> </files_modified> </observation>

These rules enforce specific locations for different test types (unit in tests/ folders, React tests co-located with components), specify the correct configuration files to use for each test type, and document common mocking patterns for Electron APIs, the filesystem, and design system components. Critical to the project's cross-platform nature is the requirement that path assertions use path.join() rather than literal separators, ensuring tests pass on both Windows and macOS CI. The rules also require specific test runner commands to be used - attempting to run React tests with the default config will fail silently.

The about.spec.ts test demonstrates a complete working example: launching the Electron app via DoctoE2EApp, waiting for window load, clicking menu items to trigger navigation, waiting for the About window to appear, and verifying its title and content. The test harness handles platform-specific concerns like different Electron process names and CI environment issues where system services may be unavailable. Tests use Playwright's Electron API (_electron.launch) seamlessly with the application's event system, allowing tests to wait for specific console messages and interact with menus programmatically. The pattern shows E2E testing is already being done and can be extended to other features.</narrative> <concepts> <concept>how-it-works</concept> <concept>pattern</concept> </concepts> <files_read> <file>src/core/about/tests/about.spec.ts</file> <file>tests/docto-e2e/electron/index.ts</file> </files_read> <files_modified> </files_modified> </observation>

Module Structure Overview\n\nTotal Modules: 77 (40% core + 60% feature)\n\nDirectory Breakdown:\n- Core modules: 31 modules (src/core/) - infrastructure, logging, IPC, i18n, etc.\n- Common modules: 6 modules (src/modules/common/) - telehealth, consultation, messaging, smart-folders, etc.\n- French modules: 14 modules (src/modules/fr/) - Billeo, Sesam-Vitale, healthcare teleservices, etc.\n- German modules: 19 modules (src/modules/de/) - Gematik services, KBV integration, etc.\n- Interoperability: 3 Zipper modules (desktop/web)\n\nModule Architecture Pattern (consistent across all):\n\\nmodule-name/\\n├── constants/ (events.ts, types.ts, product-events.ts)\\n├── main/ (main process: main.ts, module.ts, services)\\n├── renderer/ (React components, views, settings)\\n├── services/ (business logic, stores, repositories)\\n├── preloads/ (context bridge APIs)\\n├── tests/ or __tests__/ (unit/e2e specs)\\n├── module.config.ts (metadata)\\n├── index.ts (public exports)\\n└── README.md (documentation)\\n\n\n---\n\n### 2. React Component Patterns\n\nKey Patterns Identified:\n\n- Design System Dependency: All components use @doctolib/design-system-b2b (Oxygen design system)\n - Examples: Button, CardElevated, Toggle, AlertBanner, Heading, IconButton\n- Functional Components: Heavy use of hooks (useState, useEffect, useTranslation)\n- Class Components: Used selectively (e.g., ErrorBoundary for error catching)\n- IPC Communication: Components use sendIPCEvent() from @core/ipc-manager/renderer/utils\n- i18n Integration: All components …(truncated, 9178 more chars)

Each module follows an identical structure separating main process logic (Node.js), renderer interface (React), service layer, IPC communication, and tests, making the codebase highly testable and modular. The React layer uses standard patterns with functional components, design system components from Oxygen, i18n hooks, and IPC calls for main process communication. Routing is managed through React Router v6 with hash-based navigation and auto-generated settings routes from module metadata. This standardization means a single set of testing patterns and utilities can be applied consistently across all 77 modules, reducing cognitive load and enabling broad test coverage through shared infrastructure. The consistent module structure also makes it easy to add E2E tests to new modules by following established patterns from existing E2E tests like the About and SmartFolders examples.</narrative> <concepts> <concept>pattern</concept> <concept>how-it-works</concept> </concepts> <files_read> <file>docs/modules/module-catalog.md</file> <file>src/app/Router.tsx</file> <file>src/modules/common/smart-folders/module.config.ts</file> </files_read> <files_modified> </files_modified> </observation>

The unit testing layer benefits from 610 existing tests and a global mock setup covering 50+ critical dependencies (Sentry, Electron APIs, stores, loggers, IPC manager, notification system). React component testing is equally well-supported with 93 existing component tests, documented design system mocking patterns, and the happy-dom environment pre-configured. Electron and E2E testing leverage a custom-built test infrastructure (DoctoE2EApp, Fastify test server) that abstracts complexity and provides reusable utilities for window management, IPC communication, and menu interaction. The accessibility layer benefits from 427 data-testid attributes and ARIA role usage throughout the codebase, enabling resilient test queries. Critical success factors include the global test setup that pre-mocks all dependencies, consistent module architecture enabling pattern reuse, and comprehensive testing rules documented in .claude/rules/testing/ that guide developers through platform-specific considerations (path handling for Windows/macOS) and framework-specific requirements (Vitest imports, React Testing Library patterns, Playwright selectors). Together, these factors create a mature testing ecosystem where adding new tests is straightforward, discoverable, and consistent with established patterns.</narrative> <concepts> <concept>pattern</concept> <concept>how-it-works</concept> <concept>gotcha</concept> </concepts> <files_read> <file>tests/vitest/vitestSetup.ts</file> <file>.claude/rules/testing/testing-common.md</file> <file>.claude/rules/testing/testing-react.md</file> </files_read> <files_modified> </files_modified> </observation>

The exploration is complete. The user has documented their comprehensive findings in a summary plan file that captures:

Current state of Playwright infrastructure in DDV
14 modules already covered by E2E tests
Established test patterns and how to add new tests
Key constraints and recommendations
Coverage gaps and priorities
Verification commands
Critical files for reference

Final Assessment: The exploration conclusively demonstrates that Playwright E2E testing is fully operational, production-ready, and extensively used on DDV (Doctolib Pro Desktop). The project has:

✅ Playwright 1.59.1 + Electron 41.5.0 (compatible versions)
✅ 14 pre-configured test projects with real working tests
✅ Custom DoctoE2EApp Electron wrapper with complete lifecycle API
✅ Fastify test server for API mocking
✅ Special APP_PROFILE=e2e build configuration
✅ CI/CD integration with dedicated E2E workflows
✅ 722 total tests (610 unit + 93 component + 19 E2E)
✅ Comprehensive testing rules and guidelines
✅ Clear patterns for adding new E2E tests

Answer: Yes, not only is it possible to include Playwright tests on DDV, but the complete infrastructure is already in place and actively maintained. Developers can follow established patterns to add E2E tests to any of the remaining 63 modules that don't yet have E2E coverage.

--- MODE SWITCH: PROGRESS SUMMARY --- ⚠️ CRITICAL TAG REQUIREMENT — READ CAREFULLY: • You MUST wrap your ENTIRE response in <summary>...</summary> tags. • Do NOT use <observation> tags. <observation> output will be DISCARDED and cause a system error. • The ONLY accepted root tag is <summary>. Any other root tag is a protocol violation.

PROGRESS SUMMARY CHECKPOINT

Write progress notes of what was done, what was learned, and what's next. This is a checkpoint to capture progress so far. The session is ongoing - you may receive more requests and tool executions after this summary. Write "next_steps" as the current trajectory of work (what's actively being worked on or coming up next), not as post-session future work. Always write at least a minimal summary explaining current progress, even if work is still in early stages, so that users see a summary output tied to each request.

Claude's Full Response to User: Since this is an evaluation/exploration task (not a code implementation), here's the full assessment:

Playwright in DDV: Evaluation Summary

TL;DR: Not only is it possible — it's already fully operational.

What's already in place

@playwright/test 1.59.1 is installed
14 E2E test projects are configured in tests/playwright/playwright.config.ts
A custom DoctoE2EApp wrapper (tests/docto-e2e/electron/index.ts) handles Electron app lifecycle: launch, window management, DNS interception, temp dir isolation, and CI kill
A Fastify mock server (tests/docto-e2e/monolith/) simulates the Doctolib backend
npm run test:e2e runs the full suite in CI with 4 retries and JUnit output
Official rules are documented at .claude/rules/testing/testing-e2e.md

How it works

Playwright launches dist/main.js directly via _electron.launch(). Chromium's --host-resolver-rules flag redirects pro-staging.doctolib.fr → localhost:2323 at the network layer — so the real app code runs, but all HTTP goes to the local mock server.

Current coverage gap

Of 77 modules, only 14 have E2E tests. All src/modules/fr/, most src/modules/de/, and most src/modules/common/ are untested at the E2E level.

To add tests for a new module

Create src/modules/<your-module>/tests/<module>.spec.ts
Add a project entry to tests/playwright/playwright.config.ts
Follow the pattern in src/core/about/tests/about.spec.ts — it's the reference implementation
Run: npm run test:e2e -- --project=<module> --headed (debug mode)

The full evaluation is saved to /Users/USER/.claude/plans/explore-this-project-and-recursive-stearns.md.

Would you like to add Playwright tests to a specific module, or is this evaluation sufficient?

<summary> <request>Explore the Doctolib Pro Desktop (DDV) project and evaluate whether Playwright E2E testing is possible to implement on DDV</request>

<investigated> Comprehensive exploration of the DDV Electron/React project covering: - Electron version (41.5.0) and Playwright compatibility (1.59.1 installed) - Existing test infrastructure (804 test files: 610 unit + 93 component + 19 E2E specs) - Playwright configuration and setup (14 test projects pre-configured) - DoctoE2EApp custom wrapper implementation (445-line utility for Electron lifecycle management) - Test server infrastructure (Fastify-based monolith for API mocking) - Module architecture (77 modules with consistent structure) - Testing rules and guidelines (.claude/rules/testing/ comprehensive documentation) - CI/CD integration (GitHub Actions workflows for E2E execution) - Real working test examples (src/core/about/tests/about.spec.ts and others) - React component patterns (design system usage, IPC communication, i18n) - Routing and navigation (React Router v6 with hash-based routing) - Accessibility features (427 data-testid attributes, ARIA roles) </investigated>

<learned> Playwright E2E testing is not only possible on DDV—it is already fully established and production-ready: - Playwright 1.59.1 is compatible with Electron 41.5.0 - Custom DoctoE2EApp wrapper abstracts Electron app launching, window management, menu interaction, and console event listening - Tests build with APP_PROFILE=e2e, which skips health checks and enables test-specific behavior - Fastify mock server handles API mocking with dynamic port allocation per test worker - DNS interception via --host-resolver-rules remaps pro-staging.doctolib.fr to localhost - 14 modules already have E2E test coverage with established patterns - Testing infrastructure supports serial execution (workers: 1), 90-second timeouts, 4 CI retries - Global Vitest setup mocks 50+ dependencies (Sentry, Electron APIs, stores, etc.) - CI workflows (production_e2e_tests.yml, ddv_reusable_ci_*.yml) actively run E2E tests on releases - Comprehensive testing rules document platform-agnostic patterns and framework requirements </learned>

<completed> - Thorough architectural analysis of DDV Electron application structure - Complete inventory of testing infrastructure (frameworks, configs, test files) - Documentation of existing E2E test patterns and utilities - Gap analysis identifying 14 modules with E2E coverage vs 63 without - Creation of comprehensive evaluation summary (saved to .claude/plans/) - Verification that Playwright is operationally integrated with full CI/CD support - Identification of all critical files for E2E test authoring - Confirmation of real working test examples and their patterns </completed>

<next_steps> User will determine next direction: - If adding Playwright tests: follow established pattern in src/core/about/tests/about.spec.ts as reference; create module test directory; register in playwright.config.ts; write specs using DoctoE2EApp API - If exploring specific module: identify which of 63 uncovered modules would benefit most from E2E testing (complex workflows, critical business paths, IPC-heavy features) - If optimizing existing tests: review current 14 E2E test projects for patterns to extend or improve - If investigating test infrastructure: deep-dive into DoctoE2EApp utilities, monolith server configuration, or test helpers </next_steps>

<notes> Key findings that enable immediate E2E test authoring: - Established pattern (test.describe → test.beforeEach [reset/start] → test cases → test.afterEach [close]) - DoctoE2EApp provides high-level APIs: start(), clickMenuItem(), waitForPage(), waitForConsoleEvent(), getMainPage() - Test server automatically listens on dynamic ports (2323 + parallel index) - 427 data-testid attributes and ARIA roles already present in components, enabling robust selectors - Rules enforce Playwright-specific patterns: no waitForTimeout(), use waitForSelector/waitForConsoleEvent - CI environment handling: 4 retries, GitHub reporter, JUnit output - No barriers to adding E2E tests to any of 63 uncovered modules - Complete documentation exists (.claude/rules/testing/testing-e2e.md) </notes> </summary>
