What is detox?
Detox is an end-to-end testing and automation framework for mobile applications. It is designed to test mobile apps on both iOS and Android platforms, ensuring that the app works as expected from the user's perspective. Detox is known for its ability to handle asynchronous operations and its integration with popular mobile development frameworks like React Native.
What are detox's main functionalities?
End-to-End Testing
This code demonstrates a basic end-to-end test using Detox. It launches the app, checks for the visibility of a welcome screen, taps a button, and verifies that a 'Hello' screen is displayed.
const { device, expect, element, by } = require('detox');
beforeAll(async () => {
await device.launchApp();
});
describe('Example', () => {
it('should have welcome screen', async () => {
await expect(element(by.id('welcome'))).toBeVisible();
});
it('should show hello screen after tap', async () => {
await element(by.id('hello_button')).tap();
await expect(element(by.text('Hello!!!'))).toBeVisible();
});
});
Device Interaction
This code sample shows how to interact with the device using Detox. It includes actions like rotating the device to landscape mode and shaking the device.
const { device } = require('detox');
beforeAll(async () => {
await device.launchApp();
});
describe('Device Interaction', () => {
it('should rotate the device to landscape', async () => {
await device.setOrientation('landscape');
});
it('should shake the device', async () => {
await device.shake();
});
});
Synchronization
This code demonstrates Detox's synchronization capabilities. It waits for a specific element to become visible within a given timeout period.
const { device, element, by } = require('detox');
beforeAll(async () => {
await device.launchApp();
});
describe('Synchronization', () => {
it('should wait for element to be visible', async () => {
await waitFor(element(by.id('uniqueId'))).toBeVisible().withTimeout(2000);
});
});
