+## Real E2E Testing Strategy (No Mocks)
+
+GridPilot requires two distinct E2E testing strategies due to the nature of its automation adapters:
+
+1. **Strategy A (Docker)**: Test `BrowserDevToolsAdapter` with Puppeteer against a fixture server
+2. **Strategy B (Native macOS)**: Test `NutJsAutomationAdapter` on real hardware with display access
+
+### Constraint: iRacing Terms of Service
+
+- **Production**: nut.js OS-level automation only (no Puppeteer/CDP for actual iRacing automation)
+- **Testing**: Puppeteer CAN be used to test `BrowserDevToolsAdapter` against static HTML fixtures
+
+### Test Architecture Overview
+

+        FX[Static HTML Fixtures] --> FS[Fixture Server Container]
+        FS --> HC[Headless Chrome Container]

+    end
+```
+
+---
+
+### Strategy A: Docker-Based E2E Tests
+
+#### Purpose
+Test the complete 18-step workflow using `BrowserDevToolsAdapter` against real HTML fixtures without mocks.
+
+#### Architecture
+
+```yaml
+# docker/docker-compose.e2e.yml
+services:
+  # Headless Chrome with remote debugging enabled
+  chrome:
+    image: browserless/chrome:latest
+    ports:
+      - "9222:3000"
+    environment:
+      - CONNECTION_TIMEOUT=600000
+      - MAX_CONCURRENT_SESSIONS=1
+      - PREBOOT_CHROME=true
+    healthcheck:
+      test: ["CMD", "curl", "-f", "http://localhost:3000/json/version"]
+      interval: 5s
+      timeout: 10s
+      retries: 3
+
+  # Static server for iRacing HTML fixtures
+  fixture-server:
+    build:
+      context: ./fixture-server
+      dockerfile: Dockerfile
+    ports:
+      - "3456:80"
+    volumes:
+      - ../resources/iracing-hosted-sessions:/usr/share/nginx/html:ro
+    healthcheck:
+      test: ["CMD", "curl", "-f", "http://localhost:80/01-hosted-racing.html"]
+      interval: 5s
+      timeout: 10s
+      retries: 3
+```
+
+#### Fixture Server Configuration
+
+```dockerfile
+# docker/fixture-server/Dockerfile
+FROM nginx:alpine
+
+# Configure nginx for static HTML serving
+COPY nginx.conf /etc/nginx/conf.d/default.conf
+
+EXPOSE 80
+```
+
+```nginx
+# docker/fixture-server/nginx.conf
+server {
+    listen 80;
+    server_name localhost;
+    root /usr/share/nginx/html;
+    
+    location / {
+        try_files $uri $uri/ =404;
+        add_header Access-Control-Allow-Origin *;
+    }
+}
+```
+
+#### BDD Scenarios for Docker E2E
+
+```gherkin
+Feature: BrowserDevToolsAdapter Workflow Automation
+  As the automation engine
+  I want to execute the 18-step hosted session workflow
+  So that I can verify browser automation against real HTML fixtures
+
+  Background:
+    Given the Docker E2E environment is running
+    And the fixture server is serving iRacing HTML pages
+    And the headless Chrome container is connected
+
+  Scenario: Complete workflow navigation through all 18 steps
+    Given the BrowserDevToolsAdapter is connected to Chrome
+    When I execute step 2 HOSTED_RACING
+    Then the adapter should navigate to the hosted racing page
+    And the page should contain the create race button
+    
+    When I execute step 3 CREATE_RACE
+    Then the wizard modal should open
+    
+    When I execute step 4 RACE_INFORMATION
+    And I fill the session name field with "Test Race"
+    Then the form field should contain "Test Race"
+    
+    # ... steps 5-17 follow same pattern
+    
+    When I execute step 18 TRACK_CONDITIONS
+    Then the automation should stop at the safety checkpoint
+    And the checkout button should NOT be clicked
+
+  Scenario: Modal step handling - Add Car modal
+    Given the automation is at step 8 SET_CARS
+    When I click the "Add Car" button
+    Then the ADD_CAR modal should open
+    When I search for "Dallara F3"
+    And I select the first result
+    Then the modal should close
+    And the car should be added to the selection
+
+  Scenario: Form field validation with real selectors
+    Given I am on the RACE_INFORMATION page
+    Then the selector "input[name='sessionName']" should exist
+    And the selector ".form-group:has label:has-text Session Name input" should exist
+    
+  Scenario: Error handling when element not found
+    Given I am on a blank page
+    When I try to click selector "#nonexistent-element"
+    Then the result should indicate failure
+    And the error message should contain "not found"
+```

+### Strategy B: Native macOS E2E Tests
+
+#### Purpose
+Test OS-level screen automation using nut.js on real hardware. These tests CANNOT run in Docker because nut.js requires actual display access.
+
+#### Requirements
+- macOS CI runner with display access
+- Screen recording permissions granted
+- Accessibility permissions enabled
+- Real Chrome/browser window visible
+
+#### BDD Scenarios for Native E2E
+
+```gherkin
+Feature: NutJsAutomationAdapter OS-Level Automation
+  As the automation engine
+  I want to perform OS-level screen automation
+  So that I can interact with iRacing without browser DevTools
+
+  Background:
+    Given I am running on macOS with display access
+    And accessibility permissions are granted
+    And screen recording permissions are granted
+
+  Scenario: Screen capture functionality
+    When I capture the full screen
+    Then a valid image buffer should be returned
+    And the image dimensions should match screen resolution
+
+  Scenario: Window focus management
+    Given a Chrome window titled "iRacing" is open
+    When I focus the browser window
+    Then the Chrome window should become the active window
+
+  Scenario: Template matching detection
+    Given I have a template image for the "Create Race" button
+    And the iRacing hosted racing page is visible
+    When I search for the template on screen
+    Then the template should be found
+    And the location should have confidence > 0.8
+
+  Scenario: Mouse click at detected location
+    Given I have detected a button at coordinates 500,300
+    When I click at that location
+    Then the mouse should move to 500,300
+    And a left click should be performed
+
+  Scenario: Keyboard input simulation
+    Given a text field is focused
+    When I type "Test Session Name"
+    Then the text should be entered character by character
+    With appropriate delays between keystrokes
+
+  Scenario: Login state detection
+    Given the iRacing login page is displayed
+    When I detect the login state
+    Then the result should indicate logged out
+    And the login form indicator should be detected
+
+  Scenario: Safe automation - no checkout
+    Given I am on the Track Conditions step
+    When I execute step 18
+    Then no click should be performed on the checkout button
+    And the automation should report safety stop
+```

+ * These tests run against real Docker containers:
+ * - browserless/chrome: Headless Chrome with CDP exposed
+ * - fixture-server: nginx serving static HTML fixtures
+ * 
+ * Prerequisites:
+ * - Run `npm run docker:e2e:up` to start containers
+ * - Chrome available at ws://localhost:9222
+ * - Fixtures available at http://localhost:3456
+ * 
+ * IMPORTANT: These tests use REAL adapters, no mocks.
