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!');
});
CodeceptJS provides next features over standard 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 an 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.
Build an application using detox build command.
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": {
"binaryPath": "ios/build/Build/Products/Debug-iphonesimulator/example.app",
"build": "xcodebuild -project ios/example.xcodeproj -scheme example -configuration Debug -sdk iphonesimulator -derivedDataPath ios/build",
"type": "ios.simulator",
"name": "iPhone 7"
}
}
}
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.configSaves a screenshot to the output dir
