This command will take a while to add the Detox to HelloDetox app. React Natives project has a package.json file so we can add the Detox library to our project using the following command. $ brew tap wix/brewĭetox comes with great CLI tools, which can be used to set up and execute UI tests from the command line or from CI server.
#Android emulator react native on mac hot reload install#
In order to enable the support for Detox, we have to install the applesimutils library and Detox command-line tools using the following commands.
#Android emulator react native on mac hot reload code#
Tools like Appium allow test developers to create separate repositories for testing code which doesn’t always fit for CI/CD pipelines. Configure DetoxĪs Detox is a grey-box UI testing framework, we have to add the Detox code inside the main app repository. Now we have a basic React Native app ready for UI testing. This app has a welcome text with a couple of buttons links to another screen. When you hot reload app using CMD+R, you will see the app in the simulator.
For the purpose of this tutorial, let’s build a few buttons by adding this code. The React Native tutorial provides lots of examples. Now we can edit app.js file to display the content on the screen.

Let’s run the app inside the iOS simulator using the following command $ cd HelloDetoxĪlternatively, you can launch the Metro Bundler in the background and run the app from Xcode.
#Android emulator react native on mac hot reload android#
You can run the app inside the Android emulator or iOS simulator if you got any simulator open. $ npm install -g react- native-cliĪt this point, React Native will generate the boilerplate code for building both Android and iOS apps. Now you can install React Native globally and create our first HelloDetox app. Once you get the node installed, you should be able to access the ‘npm’ commands from the terminal. You can easily install those packages with Homebrew. We need a node and watchman package, to get going with React Native. We can easily create a sample app by installing a few dependencies from macOS. React Native has great documentation to get started with the basic app. To recap, you will need the followingĪs part of this tutorial, we will create a simple, new React Native app, HelloDetox and enable UI testing support using Detox.

You also need to install Node and Homebrew to download the packages required for running React Native apps. As a pre-requisite, you need a macOS with Xcode installed on it. In this tutorial, we will focus on iOS but Android-specific setup would be fairly easy once you get on with iOS. If you are already running your React Native apps, the basic requirements for running iOS and Android app in the simulator must be fulfilled. The process of setting up Detox for your existing React Native app would be fairly simple. React Native developers would love Detox as it’s faster, debuggable and can be used with any test runner like Jest or Mocha.ĭetox currently has limited support for iOS real device testing but if your app doesn’t have hardware interface then you can easily skip that part to compensate on faster and less flaky UI testing.Detox is awesome for fast feedback on your E2E testing which doesn’t need the connection to real devices.Detox is easy to be connected to any CI systems and popular cloud testing services.It’s an in-process tool and doesn’t use client-server architecture for test execution so it’s way faster than Appium or other third-party mobile test automation frameworks. Detox is a grey-box testing tool so it can access the code and data from your mobile apps.Detox monitors the asynchronous operations in the app to reduce the flakiness of finding the async elements in the app UI.Some of Detox’s great features are as follows Detox is designed to solve the problem of slowness and flakiness for mobile UI testing. The tools like Appium are completely black-box and uses client-server architecture which causes flakiness in the UI tests. Detox: End-to-End Mobile UI TestingĪs you may have known, the major problems in the mobile UI testing are slowness and flakiness. In this tutorial, we will set up some Detox tests for a simple, new React Native app. Appium is widely used for UI testing but Detox is a grey-box, faster and easy to learn tool for the UI testing of React Native apps. There are two great UI testing frameworks for React Native apps – Appium and Detox. In recent years, React Native has become a very popular technology in the race of cross-platform mobile application development but choosing a UI testing tool for React Native apps might be quite tricky.
