How to Run Detox Tests

This guide will help you set up and run Detox tests for your project.

Install Dependencies

First, navigate to the root directory of your project and install the necessary dependencies by running:

npm install

navigate to the detox folder and run npm install

Configure your server details

in detox/e2e/support/test_config.ts will provide some default values for your server, if they differ you can:

• use environment variables

  export SITE_1_URL="http://your-server:8065"
  export ADMIN_USERNAME="your-username"
  export ADMIN_PASSWORD="your-password"
  export ADMIN_EMAIL="your-email"

• create a .env file in the detox folder providing the values:

  # detox/.env
  SITE_1_URL=http://localhost:8065
  ADMIN_USERNAME=your-username
  ADMIN_PASSWORD=your-password
  ADMIN_EMAIL=your-email@example.com

Note: no need to provide all variables, only the ones that differ.

Android

Build Detox Android App

To build the Detox Android app, navigate to the detox folder and run:

npm run e2e:android-inject-settings

npm run e2e:android-build

The debug apk will be built and available at android/app/build/outputs/apk/debug/app-debug.apk

Run Detox Android Tests

Create emulator

./create_android_emulator.sh SDK_VERSION AVD_NAME

# example ./create_android_emulator.sh 34 pixel_5a_avd
# example ./create_android_emulator.sh 34 pixel_5a_avd --headless
# If we want to see the emulator logs. Run it in debug mode example ./create_android_emulator.sh 34 pixel_5a_avd --debug

To execute the Detox tests on Android, navigate to the detox folder and run:

npm run e2e:android-test

# To run a particular tests

npm run e2e:android-test <path to test file>

iOS

Build iOS Simulator

To build the iOS simulator for Detox, from the project folder run:

npm run e2e:ios-build

This will build the Simulator .zip file at the root folder.

Create a folder named mobile-artifacts at the project root. Move the zip file under mobile-artifacts and unzip it there.

# From project root
mkdir mobile-artifacts

Configure your local

Update detox/.detoxrc.json to specify which device you want to run it. Change:

 "device": {
     "type": "__DEVICE_NAME__",
     "os": "__DEVICE_OS_VERSION__"
 },

to something like:

 "device": {
     "type": "iPhone 17 Pro",
     "os": "iOS 26.4"
 },

To get your values run xcrun simctl list devices to find both the device and iOS version.

Run iOS Tests

To execute the Detox tests on iOS, navigate to the detox folder and run:

npm run e2e:ios-test

# To run a particular tests

npm run e2e:android-test path to test file.

Disabling Password Autofill

from iOS v26 password autofill can interfere with login tests by automatically filling credentials. To disable this feature on your simulator:

# Interactive mode - select simulator from list
npm run e2e:ios-disable-autofill

# Or specify simulator ID directly
npm run e2e:ios-disable-autofill -- --simulator-id SIMULATOR_UDID

When to use this:

• if using iOS 26 or later
• Before running iOS E2E tests if you notice password fields being auto-filled
• When login tests fail unexpectedly due to autofill interference
• After creating a new iOS simulator for testing

Note: CI environments automatically disable this setting, so this is only needed for local development.

Finding your simulator ID:

xcrun simctl list devices | grep Booted

TIP : For iOS, you can download the simulator from ~Mobile: Test build or ~Release: Mobile Apps channel in the community.

Results

The Local Runs generate artifacts under detox/artifacts/ios-debug-** or detox/artifacts/android-debug-**. You can see the html report, failure screenshot under that folder.

Playbooks Tests (AI-Powered Testing)

The Playbooks tests leverage AI-powered testing through the Wix Pilot framework, enabling natural language test creation and execution.

How It Works

The Playbooks tests utilize the pilot library, which connects to Anthropic Claude via the ClaudePromptHandler. This innovative approach allows you to:

• Write tests using natural language prompts
• Automatically translate prompts into executable test steps
• Maintain tests more intuitively through conversational interfaces
• Handle complex scenarios with AI-generated test logic

The system integrates seamlessly with your existing Detox test infrastructure while adding AI capabilities.

Best Practices

For reliable and effective Playbooks tests, follow these guidelines from the Pilot Best Practices Guide:

1. Prompt Clarity:

   • Write clear, concise prompts
   • Use specific action-oriented language
   • Avoid ambiguous phrasing

2. Test Design:

   • Keep prompts focused on single scenarios
   • Use deterministic language to prevent flaky tests
   • Structure complex tests as sequences of simple prompts

3. Maintenance:

   • Review AI-generated test steps before committing
   • Version control both prompts and generated code
   • Monitor test stability regularly

4. Integration:

   • Combine AI tests with traditional assertions
   • Use AI for complex scenarios, traditional methods for simple verifications
   • Document which tests are AI-generated

Getting Started

To run Playbooks tests:

1. Set up your environment:

   export ANTHROPIC_API_KEY='your-api-key-here'
   

2. Run tests normally:

   • The system will automatically initialize the ClaudePromptHandler when the API key is detected
   • No additional configuration is required beyond the API key

3. Execution examples:

   # Run all Playbooks tests
   npm run e2e:android-test tests/playbooks/
   
   # Run a specific Playbook test
   npm run e2e:ios-test tests/playbooks/playbooks_basic.e2e.ts
   

Technical Notes

• The Pilot framework handles the translation between natural language prompts and executable code
• Tests are cached locally after generation for faster subsequent runs
• All AI interactions are logged in the test artifacts for debugging
• The system falls back to traditional testing methods if the API key isn't available
