Detox Helper for CodeceptJS

Testing Mobile Apps on iOS and Android can look like this:

I.setLandscapeOrientation();
I.fillField('#text', 'a new text');
I.see('a new text', '#textValue');
I.dontSeeElement('#createdAndVisibleText');
I.click({ ios: '#GoButton', android: 'Button' });
I.waitForElement('#createdAndVisibleText', 20);
I.seeElement('#createdAndVisibleText');
I.runOnAndroid(() => {
  I.click('Save');
  I.see('Text Saved', '#message');
});
I.runOnIOS(() => {
  I.click('SAVE');
  I.see('SAVED!');
});

Example output:

CodeceptJS provides next features over standard Detox:

• Unified API. The same test can be executed in Appium or Detox. Unified API helps different teams to use the same syntax and easy port tests from one engine to another.
• Interactive pause. When starting/stopping an application takes a long time, debugging and writing tests can be hard. CodeceptJS solves this by pausing an execution and letting you try different commands and locators. With this feature a test can be writtern during one running session.
• One Test For Android and IOS. When application differs on Android and IOS you can provide corresponding system-related locators for both systems. When needed a different code can be executed for Android and IOS keeping it inside the same test.

Detox

Extends Helper

This is a wrapper on top of Detox library, aimied to unify testing experience for CodeceptJS framework. Detox provides a grey box testing for mobile applications, playing especially good for React Native apps.

Detox plays quite differently from Appium. To establish detox testing you need to build a mobile application in a special way to inject Detox code. This why Detox is grey box testing solution, so you need access to application source code, and a way to build and execute it on emulator.

Comparing to Appium, Detox runs faster and more stable but requires an additional setup for build.

Setup

1. Install and configure Detox

2. Build an application using detox build command.

3. Install CodeceptJS and detox-helper:

   npm i @codeceptjs/detox-helper --save

Detox configuration is required in package.json under detox section.

If you completed step 1 and step 2 you should have a configuration similar this:

 "detox": {
    "configurations": {
      "ios.sim.debug": {
        "device": "simulator",
        "app": "ios.debug"
      }
    },
    "apps": {
      "ios.debug": {
        "type": "ios.app",
        "binaryPath": "../test/ios/build/Build/Products/Debug-iphonesimulator/MyTestApp.app",
        "build": "xcodebuild -workspace ../test/ios/MyTestApp.xcworkspace -scheme MyTestApp -configuration Debug -sdk iphonesimulator -derivedDataPath ../test/ios/build"
      }
    },
    "devices": {
      "simulator": {
        "type": "ios.simulator",
        "device": {
          "type": "iPhone 15"
        }
      }
    }
  }

Configuration

Besides Detox configuration, CodeceptJS should also be configured to use Detox.

In codecept.conf.js enable Detox helper:

helpers: {
   Detox: {
     require: '@codeceptjs/detox-helper',
     configuration: '<detox-configuration-name>',
   }
}

It's important to specify a package name under require section and current detox configuration taken from package.json.

Options:

• configuration - a detox configuration name. Required.
• reloadReactNative - should be enabled for React Native applications.
• reuse - reuse application for tests. By default, Detox reinstalls and relaunches app.
• registerGlobals - (default: true) Register Detox helper functions by, element, expect, waitFor globally.
