+# Pretix Widget E2E Tests
+
+End-to-end tests for the pretix widget using Python Playwright and pytest.
+
+## Overview
+
+These tests verify the complete widget experience from a user's perspective, including:
+- Widget embedding and initialization
+- Product browsing and variations
+- Quantity controls and free price inputs
+- Cart management and checkout flows
+- Iframe/new tab integration
+- Responsive behavior and accessibility
+
+## Installation
+
+### Prerequisites
+
+- Python 3.11+
+- Virtual environment activated
+- Django test database configured
+
+### Setup
+
+1. **Activate the virtual environment:**
+   ```bash
+   source env/bin/activate
+   ```
+
+2. **Install pytest-playwright:**
+   ```bash
+   pip install pytest-playwright
+   ```
+
+3. **Install browser binaries:**
+   ```bash
+   # Install all browsers (Chromium, Firefox, WebKit)
+   python -m playwright install
+
+   # Or install specific browsers only
+   python -m playwright install chromium
+   python -m playwright install firefox
+   ```
+
+4. **Verify installation:**
+   ```bash
+   pytest src/tests/e2e/ --collect-only
+   ```
+
+## Running Tests
+
+### Basic Usage
+
+```bash
+# Run all E2E tests
+pytest src/tests/e2e/
+
+# Run specific test file
+pytest src/tests/e2e/test_widget_embedding.py
+
+# Run specific test
+pytest src/tests/e2e/test_widget_cart.py::TestCartBasics::test_add_to_cart_and_open_checkout
+```
+
+### Browser Selection
+
+```bash
+# Run with specific browser (default: chromium)
+pytest src/tests/e2e/ --browser firefox

+```
+
+## Test Organization
+
+```
+src/tests/e2e/
+├── conftest.py                    # Shared fixtures and configuration
+├── test_widget_embedding.py       # Widget loading and initialization
+├── test_widget_variations.py      # Product variations and expansion
+├── test_widget_quantity_controls.py  # Quantity inputs, checkboxes, free price
+└── test_widget_cart.py            # Cart management and checkout flow
+```
+
+### Key Fixtures
+
+Defined in `conftest.py`:
+
+- **`widget_organizer`** - Creates test organizer (testorg)
+- **`widget_event`** - Creates test event (testevent)
+- **`widget_items`** - Creates General Admission ($50) and VIP Ticket ($150)
+- **`widget_item_with_variations`** - Creates t-shirt with S/M/L/XL sizes
+- **`widget_item_single_select`** - Creates item with order_max=1 (checkbox)
+- **`widget_item_free_price`** - Creates pay-what-you-want donation item
+- **`widget_item_sold_out`** - Creates sold out item
+- **`widget_event_series`** - Creates event series with 15 subevents
+- **`widget_page`** - Enhanced page object with helper methods
+- **`live_server_url`** - Django live server URL
+
+### WidgetPage Helper Methods
+
+The `widget_page` fixture provides convenient methods:
+
+```python
+def test_example(widget_page, live_server_url, widget_event, widget_items):
+    # Navigate to event
+    widget_page.goto_event(live_server_url, 'testorg', 'testevent')
+
+    # Wait for widget to load
+    widget_page.wait_for_widget_load()
+
+    # Select item quantity
+    widget_page.select_item_quantity('General Admission', 2)
+
+    # Expand variations
+    widget_page.expand_variations('Event T-Shirt')
+
+    # Select variation quantity
+    widget_page.select_variation_quantity('Event T-Shirt', 'Medium', 1)
+
+    # Click buy button
+    widget_page.click_buy_button()
+
+    # Wait for iframe checkout
+    iframe = widget_page.wait_for_iframe_checkout()
+
+    # Close iframe
+    widget_page.close_iframe()
+```
+
+## Common Test Patterns
+
+### Basic Widget Load Test
+
+```python
+@pytest.mark.django_db
+def test_widget_loads(page, live_server_url, widget_organizer, widget_event, widget_items, widget_page):
+    widget_page.goto_event(live_server_url, widget_organizer.slug, widget_event.slug)
+    widget_page.wait_for_widget_load()
+
+    # Verify content
+    expect(page.locator(f'text="{widget_event.name}"')).to_be_visible()
+```
+
+### Variation Interaction Test
+
+```python
+@pytest.mark.django_db
+def test_variations(page, live_server_url, widget_organizer, widget_event, widget_item_with_variations, widget_page):
+    item, variations = widget_item_with_variations
+
+    widget_page.goto_event(live_server_url, widget_organizer.slug, widget_event.slug)
+    widget_page.wait_for_widget_load()
+
+    # Expand variations
+    widget_page.expand_variations(item.name)
+
+    # Verify all variations visible
+    for variation in variations:
+        expect(page.locator(f'text="{variation.value}"')).to_be_visible()
+```
+
+### Cart Flow Test
+
+```python
+@pytest.mark.django_db
+def test_checkout(page, context, live_server_url, widget_organizer, widget_event, widget_items, widget_page):
+    widget_page.goto_event(live_server_url, widget_organizer.slug, widget_event.slug)
+    widget_page.wait_for_widget_load()
+
+    # Add items
+    widget_page.select_item_quantity(widget_items[0].name, 2)
+    widget_page.click_buy_button()
+
+    # Wait for checkout to open
+    page.wait_for_timeout(2000)
+
+    # Verify cookies set
+    cookies = context.cookies()
+    assert len(cookies) > 0
+```
+
+## Debugging
+
+### View Browser in Action
+
+Run tests with `--headed` flag to see the browser:
+
+```bash
+pytest src/tests/e2e/test_widget_embedding.py::TestWidgetEmbedding::test_widget_loads_successfully --headed
+```
+
+### Slow Down for Observation
+
+Use `--slowmo` to slow operations (milliseconds):
+
+```bash
+pytest src/tests/e2e/ --headed --slowmo 1000
+```
+
+### Interactive Debugging
+
+Use `--pdb` to drop into debugger on failure:
+
+```bash
+pytest src/tests/e2e/test_widget_cart.py --headed --pdb
+```
+
+### Record Videos
+
+Generate video recordings of test runs:
+
+```bash
+pytest src/tests/e2e/ --video on
+
+# Videos saved to: test-results/
+```
+
+### Generate Trace Files
+
+For detailed debugging with Playwright Inspector:
+
+```bash
+pytest src/tests/e2e/ --tracing on
+
+# View traces with:
+playwright show-trace test-results/.../trace.zip
+```
+
+## Troubleshooting
+
+### Browser binaries not found
+
+**Error:** `playwright._impl._errors.Error: Executable doesn't exist`
+
+**Solution:**
+```bash
+python -m playwright install chromium
+```
+
+### Django database errors
+
+**Error:** `django.db.utils.OperationalError: no such table`
+
+**Solution:**
+```bash
+# Run migrations in test settings
+DJANGO_SETTINGS_MODULE=tests.settings python manage.py migrate
+```
+
+### Live server not starting
+
+**Error:** `OSError: [Errno 98] Address already in use`
+
+**Solution:** Kill processes using the port or let pytest assign random ports automatically (default behavior).
+
+### Widget not loading
+
+**Issue:** Widget displays loading spinner indefinitely
+
+**Debug steps:**
+1. Check browser console for JavaScript errors:
+   ```python
+   page.on("console", lambda msg: print(f"Console: {msg.text}"))
+   ```
+
+2. Verify widget JavaScript is built:
+   ```bash
+   ls -l src/pretix/static/pretixpresale/widget/dist/
+   ```
+
+3. Check Django static files are served:
+   ```bash
+   DJANGO_SETTINGS_MODULE=tests.settings python manage.py collectstatic --noinput
+   ```
+
+### Timeout errors
+
+**Error:** `playwright._impl._errors.TimeoutError: Timeout 10000ms exceeded`
+
+**Solution:** Increase timeout for specific operations:
+```python
+page.wait_for_selector('.pretix-widget', timeout=30000)
+```
+
+Or globally in conftest.py:
+```python
+@pytest.fixture
+def page(context):
+    page = context.new_page()
+    page.set_default_timeout(30000)  # 30 seconds
+    yield page
+    page.close()
+```
+
+### Cookie issues
+
+**Issue:** Cart cookies not being set
+
+**Debug:**
+```python
+# Print all cookies
+cookies = context.cookies()
+for cookie in cookies:
+    print(f"{cookie['name']}: {cookie['value']}")
+```
+
+Check domain/path settings match your test server.
+
+## CI/CD Integration
+
+### GitHub Actions Example
+
+```yaml
+name: E2E Tests
+
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+
+      - name: Set up Python
+        uses: actions/setup-python@v4
+        with:
+          python-version: '3.11'
+
+      - name: Install dependencies
+        run: |
+          pip install -r requirements.txt
+          pip install pytest-playwright
+          python -m playwright install --with-deps chromium
+
+      - name: Run E2E tests
+        run: |
+          pytest src/tests/e2e/ --browser chromium --video on
+
+      - name: Upload test artifacts
+        if: always()
+        uses: actions/upload-artifact@v3
+        with:
+          name: test-results
+          path: test-results/
+```
+
+## Configuration
+
+### setup.cfg
+
+Playwright configuration is in `/home/rash/Projects/pretix/src/setup.cfg`:
+
+```ini
+[tool:pytest]
+DJANGO_SETTINGS_MODULE = tests.settings
+addopts = -rw
+# Uncomment for debugging:
+# addopts = -rw --headed --slowmo 500
+# --browser chromium
+```
+
+### Browser Context Args
+
+Customize in `conftest.py`:
+
+```python
+@pytest.fixture(scope="session")
+def browser_context_args(browser_context_args):
+    return {
+        **browser_context_args,
+        "viewport": {"width": 1280, "height": 720},
+        "locale": "en-US",
+        "timezone_id": "America/New_York",
+    }
+```
+
+## Writing New Tests
+
+### Test Structure
+
+```python
+import pytest
+from playwright.sync_api import Page, expect
+
+
+@pytest.mark.django_db
+class TestFeatureName:
+    """Test description."""
+
+    def test_specific_behavior(
+        self,
+        page: Page,
+        live_server_url: str,
+        widget_organizer,
+        widget_event,
+        widget_items,
+        widget_page
+    ):
+        """
+        Test should description.
+
+        Given: initial state
+        When: action occurs
+        Then: expected outcome
+        """
+        # Arrange
+        widget_page.goto_event(live_server_url, widget_organizer.slug, widget_event.slug)
+        widget_page.wait_for_widget_load()
+
+        # Act
+        widget_page.select_item_quantity(widget_items[0].name, 1)
+
+        # Assert
+        expect(page.locator('.some-element')).to_be_visible()
+```
+
+### Best Practices
+
+1. **Use descriptive test names** - `test_variation_quantity_updates_on_input` vs `test_var`
+2. **Use WidgetPage helpers** - Encapsulate common interactions
+3. **Wait for elements** - Use `expect().to_be_visible()` instead of `wait_for_timeout()`
+4. **Mark Django tests** - Always use `@pytest.mark.django_db` when accessing database
+5. **Clean test data** - Use fixtures, let pytest handle cleanup
+6. **Verify user-visible behavior** - Test what users see, not implementation details
