Learn about React Native apps, and get expert advice on how to do React Native testing with Appium. React Native lets you create truly native apps and doesn't compromise your users' experiences. The way to find which is a first name and which is a last name with no unique IDs is by using the context and the labels next to each. Let’s take a look at Appium and Espresso, the two most popular automated frameworks for Android testing. This article is based on a webinar that was hosted by HeadSpin in June 2019. While inspecting the elements through Appium desktop or the Macaca inspector, you will face some challenges. The example below demonstrates the object tree of a React Native application. First, we’ll need to add Appium and a couple of other libraries to our project. Unfortunately, building native apps on different mobile platforms (Android and iOS) often involves using a host of different tools and methodologies, based on whatever Google or Apple dictate to their developer communities. You can now upload your React Native application to 21, author tests in minutes, even without IDs, and execute them on simulators or Perfecto’s real devices with a single click. Setting up your testing environment — testing can be done locally which is limited in scale and maintenance, or through the. Changing the API response format — XML requires parsing and traversing which is slower than direct object access using self.useJSONSource=True in the desired capabilities. Direct object pulling reduced execution time by ~20%. A lot of "mosts"—need some iOS/Android experience, Mostly no need to learn iOS or Android app dev, Reliant on RN team for SDK compatibility updates, Good debugging toolkit for rapid development, Difficult to write truly platform-specific UX, Reliant on project owned by FB (though now under MIT license). Testing React Native Apps Using Appium. Finally, we added neighboring elements and context. Appium is an open-source test automation framework that allows creating tests for mobile web, hybrid and native applications. JavaScriptCore is an execution engine — the same as in Safari Browser — which runs the React Native code. It functions same like Selenium server which runs in the background like a Selenium server. Detox, unlike Appium, is packed into the app so it will have insight into the application it is testing. It does so by using the React Native bridge. Since React Native apps are executed inside JavaScriptCore, in most cases the WebDriver will not be exposed to the IDs unless the developers have plugged in special-purpose test IDs/accessibility IDs.

The end-user experience is (at least in principle) exactly the same as any native mobile app built with the first-party platform SDKs, but the developer experience is that of a web developer, writing in React-flavoured JavaScript, and using JSX along with a CSS equivalent for structure and styling. It provides a core set of platform agnostic native components like View, Text, and Image that map directly to the platform’s native UI building blocks.

Developing a mobile app for iOS and Android can be accomplished either using Native Swift and Java or by using hybrid frameworks. Oops! NOTE Choosing to build a hybrid app was always a way out of the double-platform problem, but hybrid apps came with lots of perceived UX issues. Currently, there are especially two end-to-end testing frameworks which are interesting for React Native developers: Detox and Appium. Appium is an open-source tool for automating UI tests for cross platform application and mobile applications. But the developer experience is that of a web developer, writing in React-flavored JavaScript, and using JSX along with a CSS equivalent for structure and styling. It’s also fairly complicated. To overcome the challenges mentioned above and make Appium work well with React Native applications, my company 21 implemented a number of changes: To expedite the process, we combined multiple solutions: Think about a registration form with three TextEdit elements located next to each other. It means that we have to take care of launching and terminating the packager too. Appium is based on a client-server architecture. Note. Appium is an open source, cross-platform test automation tool for native, hybrid and mobile web and desktop apps. Jest can be combined with another library (like react-native-testing-library), to get a little more fancy and test at the component level (though again, this is not testing involving native UI components, only virtual components). – duncwa Apr 19 '17 at 1:20 For apps build on React Native use Appium to work with the Native!
