+# E2E Tests for pos-module-payments-stripe
+
+This directory contains end-to-end tests for the Stripe payments module using Playwright.
+
+## Current Status
+
+**All tests are currently SKIPPED** because the required test application does not exist.
+
+The test app (tests/post_import/app/) with pages like `/test-stripe-payment` needs to be created before these tests can run. All 6 test files require the test app and will be skipped until it is implemented.
+
+## Overview
+
+The test suite is designed to verify the Stripe Checkout integration, including:
+- Payment page rendering
+- Checkout session creation
+- Webhook handling (success, expiration, failures)
+- Error scenarios (invalid transactions, missing API keys)
+- URL parameter preservation
+- Multiple payment attempts
+
+## Prerequisites
+
+1. **Node.js and npm** installed
+2. **Playwright** installed via `npm install`
+3. **MPKIT_URL** environment variable set to your platformOS instance
+4. **pos-cli** configured with environment access
+5. **Test application** deployed (currently missing - see note above)
+
+## Test Setup
+
+### Local Development Setup
+
+```bash
+# From the pos-module-payments-stripe directory
+
+# 1. Install dependencies
+npm install
+
+# 2. Set environment variable
+export MPKIT_URL=https://your-instance.staging.oregon.platform-os.com
+
+# 3. Run tests (currently all tests will be skipped)
+npm run pw-tests
+```
+
+### What Needs to Be Created
+
+The test application needs to be created in `tests/post_import/app/` with:
+- **Test pages**: `/test-stripe-payment` (GET), `/test-stripe-payment-post` (POST), `/test-stripe-webhook` (POST)
+- **Test configuration**: `tests/post_import/app/config.yml`
+- **Module dependencies**: core, payments, payments_stripe need to be set up for test environment
+
+Until the test app is created, all tests will be skipped.
+
+## Running Tests
+
+### Run all tests
+```bash
+npm run pw-tests
+```
+
+### Run specific test file
+```bash
+npx playwright test tests/stripe-payment-page-load.spec.ts
+```
+
+### Run tests in headed mode (see browser)
+```bash
+npx playwright test --headed
+```
+
+### Run tests with UI mode
+```bash
+npx playwright test --ui
+```
+
+### Debug a test
+```bash
+npx playwright test --debug tests/stripe-payment-page-load.spec.ts
+```
+
+## Test Structure
+
+All tests are currently skipped due to missing test app.
+
+### Existing Test Files (All Skipped)
+- **stripe-payment-page-load.spec.ts**: Would verify payment page renders correctly
+- **stripe-checkout-session-create.spec.ts**: Would test checkout session creation and Stripe redirect
+- **stripe-missing-api-key.spec.ts**: Would test graceful failure without Stripe API key
+- **stripe-url-parameters.spec.ts**: Would verify URL parameter preservation (3 test cases)
+- **stripe-multiple-attempts.spec.ts**: Would test multiple payment attempts
+- **verify-stripe-key.spec.ts**: Would verify Stripe API key is working
+
+## Test Environment Limitations
+
+### What We Can Test
+- ✅ Transaction creation
+- ✅ Checkout session URL generation
+- ✅ Webhook handler logic (via simulation)
+- ✅ Transaction status updates
+- ✅ Success/failure redirects
+- ✅ Error handling
+
+### What We Cannot Test
+- ❌ Actual Stripe checkout UI (external, hosted by Stripe)
+- ❌ Real payment processing (requires test Stripe account)
+- ❌ Webhook signature validation (requires Stripe webhook secret)
+
+## Test Pages
+
+### /test-stripe-payment (GET)
+Displays a payment form with:
+- Transaction details (amount, currency, gateway)
+- "Start Payment" button
+- Success/failure messages (based on query params)
+
+### /test-stripe-payment-post (POST)
+Handles form submission:
+- Creates a transaction via payments module
+- Generates Stripe checkout session
+- Redirects to Stripe or returns error
+
+### /test-stripe-webhook (POST)
+Webhook simulator for testing:
+- Accepts: `event_type`, `transaction_id`, `payment_status`
+- Simulates Stripe webhook payload
+- Calls transaction completion logic
+- Returns success/error response
+
+## CI Integration
+
+Tests run automatically on GitHub Actions when:
+- Pull requests are opened/updated
+- Code is pushed to main branch
+- Manual workflow dispatch
+
+The workflow:
+1. Deploys test application to staging environment
+2. Runs all E2E tests
+3. Generates HTML report
+4. Uploads test results as artifacts
+
+## Viewing Test Results
+
+### Locally
+After running tests, view the HTML report:
+```bash
+npx playwright show-report playwright-report
+```
+
+### CI
+Test reports are available as workflow artifacts in GitHub Actions.
+
+## Test Configuration
+
+Configuration is in `playwright.config.ts`:
+- **Base URL**: From `MPKIT_URL` environment variable
+- **Browser**: Desktop Chrome
+- **Retries**: 2 on CI, 0 locally
+- **Workers**: 3 parallel workers
+- **Screenshots**: Only on failure
+- **Traces**: Retained on failure
+
+## Troubleshooting
+
+### Tests fail with "Cannot find module"
+```bash
+npm install
+```
+
+### Tests fail with "baseURL not set"
+```bash
+export MPKIT_URL=https://your-instance.staging.oregon.platform-os.com
+```
+
+### Tests are all skipped
+The test application does not exist yet. Create the test app in `tests/post_import/app/` following the pattern from pos-module-payments-example-gateway, then remove `.skip` from the test files.
+
+### Checkout fails with API key error
+This is expected in test environments without valid Stripe API keys. The tests are designed to handle this gracefully and verify error handling.
+
+## Writing New Tests
+
+1. Create a new `.spec.ts` file in `tests/`
+2. Import Playwright test utilities: `import { test, expect } from '@playwright/test';`
+3. Use `test.describe()` for grouping related tests
+4. Use `test.step()` for logical test steps
+5. Follow existing patterns for consistency
+
+Example:
+```typescript
+import { test, expect } from '@playwright/test';
+
+test.describe('My Test Suite', () => {

+# Stripe Checkout E2E Test Plan
+
+## Overview
+
+This test plan covers end-to-end testing of the Stripe Checkout integration for the pos-module-payments-stripe module. The tests focus on verifiable flows within our control, acknowledging that actual Stripe checkout UI and payment processing are external dependencies.
+
+## Test Environment
+
+- **Module**: pos-module-payments-stripe
+- **Dependencies**: pos-module-core, pos-module-payments
+- **Test Framework**: Playwright
+- **Browser**: Desktop Chrome
+- **Deployment**: Tests run against staging/development platformOS instances
+
+## Scope
+
+### In Scope ✅
+- Payment page rendering and UI
+- Transaction creation via payments module
+- Checkout session URL generation
+- Webhook event handling (simulated)
+- Transaction status updates
+- Success/failure redirects
+- Error handling and edge cases
+- URL parameter preservation
+
+### Out of Scope ❌
+- Actual Stripe-hosted checkout UI interaction
+- Real payment processing with cards
+- Stripe webhook signature validation (requires secrets)
+- Stripe API key validation (may not be configured in test environments)
+
+## Test Suites
+
+### Suite 1: Core Checkout Flow (Priority 1)
+
+#### Test 1.1: Payment Page Load
+**File**: `stripe-payment-page-load.spec.ts`
+
+**Steps**:
+1. Navigate to `/test-stripe-payment`
+2. Verify page heading "Stripe Payment Test" is visible
+3. Verify transaction details section exists
+4. Verify amount "$50.00 USD" is displayed
+5. Verify "Start Payment with Stripe" button exists and is clickable
+
+**Expected Results**:
+- Page loads successfully
+- All UI elements are visible and functional
+- No console errors
+
+**Status**: ✅ Implemented
+
+---
+
+#### Test 1.2: Checkout Session Creation
+**File**: `stripe-checkout-session-create.spec.ts`
+
+**Steps**:
+1. Navigate to `/test-stripe-payment`
+2. Click "Start Payment with Stripe" button
+3. Wait for navigation
+
+**Expected Results**:
+- Transaction is created in database
+- One of the following occurs:
+  - Redirect to `checkout.stripe.com` (if valid API keys)
+  - Error handling occurs gracefully (if no API keys)
+  - Redirect back to test page with error (if configuration issue)
+- No unhandled exceptions
+
+**Status**: ✅ Implemented
+
+---
+
+#### Test 1.3: Webhook - Checkout Completed (Success)
+**File**: `stripe-webhook-success.spec.ts`
+
+**Steps**:
+1. Create a transaction by submitting payment form
+2. Extract transaction ID from response
+3. Simulate `checkout.session.completed` webhook with `payment_status: 'paid'`
+4. Verify webhook response indicates success
+5. Navigate to success URL with transaction ID
+6. Verify success message is displayed
+
+**Expected Results**:
+- Webhook processes successfully
+- Transaction status updated to 'succeeded'
+- Success page displays "Payment Successful!" message
+- Transaction ID is shown on success page
+
+**Status**: ✅ Implemented
+
+---
+
+#### Test 1.4: Webhook - Checkout Expired
+**File**: `stripe-webhook-expired.spec.ts`
+
+**Steps**:
+1. Create a transaction
+2. Extract transaction ID
+3. Simulate `checkout.session.expired` webhook

+- Transaction ID displayed on result pages
+
+**Status**: ✅ Implemented
+
+---
+
+#### Test 3.2: Multiple Payment Attempts
+**File**: `stripe-multiple-attempts.spec.ts`
+
+**Steps**:
+1. Create first payment attempt
+2. Note transaction ID
+3. Navigate back to payment page
+4. Create second payment attempt
+5. Note second transaction ID
+6. Verify different transactions created
+7. Complete first transaction via webhook
+8. Verify can still initiate new payments
+
+**Expected Results**:
+- Each attempt creates a new transaction
+- Transaction IDs are unique
+- Completing one transaction doesn't block new payments
+- Old transactions remain accessible
+
+**Status**: ✅ Implemented
+
+---
+
+## Test Data
+
+### Transactions
+- **Amount**: $50.00 (5000 cents)
+- **Currency**: USD
+- **Gateway**: stripe
+- **Payer ID**: test_payer
+
+### Webhook Events
+- `checkout.session.completed` - Successful payment
+- `checkout.session.expired` - Expired session
+- `checkout.session.async_payment_succeeded` - Async payment success (future)
+- `checkout.session.async_payment_failed` - Async payment failure (future)
+
+## Test Execution
+
+### Prerequisites
+1. platformOS instance deployed with test files
+2. `MPKIT_URL` environment variable set
+3. Node.js and Playwright installed
+
+### Run All Tests
+```bash
+npm run pw-tests
+```
+
+### Run Specific Suite
+```bash
+npx playwright test tests/stripe-payment-page-load.spec.ts
+npx playwright test tests/stripe-webhook-success.spec.ts
+```
+
+## Success Criteria
+
+- ✅ All tests pass on clean deployment
+- ✅ Tests are deterministic (consistent results)
+- ✅ Tests complete in reasonable time (< 5 minutes total)
+- ✅ Test failures clearly indicate the problem
+- ✅ No false positives or flaky tests
+- ✅ Tests work in CI environment
+
+## Known Limitations
+
+1. **Stripe Checkout UI**: Cannot test the actual Stripe-hosted checkout page UI or payment form interactions
+2. **Payment Processing**: Cannot test real card processing without live Stripe integration
+3. **Webhook Signatures**: Webhook signature validation is not tested (requires Stripe signing secret)
+4. **API Keys**: Tests assume API keys may not be configured and handle that gracefully

+# Stripe Payments Module - API Test Plan
+
+## Application Overview
+
+This test plan provides comprehensive API test coverage for the pos-module-payments-stripe module. The module integrates Stripe payment processing with platformOS through the generic payments module, providing Stripe Checkout sessions, Connected Accounts for marketplace functionality, webhook handling, payment operations (charges, refunds, payment intents), and customer management.
+
+**Testing Approach:**
+Since this is an API-focused module without a user interface, tests use Playwright's request context to make API calls to platformOS pages/endpoints that invoke Liquid commands. The module exposes functionality through:
+- Liquid commands (invoked via test pages)
+- Webhook endpoints (POST /payments/stripe/webhooks)
+- Transaction management (via payments module)
+
+**Test Environment Requirements:**
+- Stripe test API keys configured (sk_test_...)
+- Module deployed to test environment
+- Test pages created to invoke commands
+- Stripe webhook endpoints configured
+
+**Key Test Areas:**
+1. Transaction Management - Core payment transaction lifecycle
+2. Checkout Sessions - Stripe Checkout integration
+3. Connected Accounts - Marketplace/platform account management
+4. Webhooks - Event handling and signature validation
+5. Payment Operations - Charges, refunds, payment intents
+6. Customer Management - Stripe customer storage/retrieval
+7. Error Handling - Validation, API errors, edge cases
+8. Balance & Reporting - Transaction history and balance queries

+# Stripe Payments Module - Webhook API Test Plan
+
+## Application Overview
+
+This test plan provides comprehensive API test coverage for the pos-module-payments-stripe webhook endpoints. The module exposes three webhook endpoints that can be tested directly without requiring additional test infrastructure:
+
+1. `/payments/stripe/webhooks` - Handles standard Stripe events (charge.succeeded, charge.pending, charge.failed, checkout.session.expired, setup_intent.succeeded)
+2. `/payments/stripe/webhooks_connect` - Handles Stripe Connect events (payout.paid, account.updated)
+3. `/payments/stripe/checkout_session_completed_webhook` - Handles checkout.session.completed events
+
+**Testing Approach:**
+All tests use Playwright's request context to send HTTP POST requests directly to webhook endpoints. Tests verify:
+- Webhook signature validation (valid/invalid signatures)
+- Event processing logic for different event types
+- Transaction status updates after webhook processing
+- Error handling (missing signatures, invalid payloads, non-existent transactions)
+- Idempotency (duplicate webhook handling)
+- Multi-tenant routing (webhooks from different hosts)
+
+**Key Constraints:**
+- Tests work against deployed module without modification
+- No test pages or helper endpoints required
+- Tests use GraphQL queries to verify transaction state changes
+- Webhook signatures must be generated correctly using HMAC-SHA256
+
+**Prerequisites:**
+- Module deployed to platformOS instance
+- Stripe API key configured (stripe_sk_key variable)
+- Webhook endpoints registered in Stripe
+- Test environment URL set in MPKIT_URL environment variable
+
