Detox VS async-storage

Nope. Not even on 0.71 yet https://github.com/wix/Detox/issues/3884

This article offers an overview of React Native testing, but there’s so much more to learn! I encourage you to explore other testing techniques and tools, like Snapshot Testing, Detox, and React Native Testing Library. Choose the ones that work best for your project, and keep learning!

I used Detox to test React Native apps. At that time, Detox was so "cool", saving both the time and effort of the dev team and the tester team. However, later on, I saw the complexity, as well as the "difficulty" with new team members, and that's when Maestro came to me as a savior. I know Maestro through an article on dev.to, but my team's "noob" is true 😂 (but my teammates don't believe it).

End-to-end testing is completely different on React Native, however. None of the Selenium-based E2E testing tools will work; neither will newer tools like Cypress or Playwright. You may have expected this - these are all DOM-based, and there’s no DOM in React Native. So instead developers will have to learn Detox or Appium.

Detox is a testing and automation tool for React Native and React web applications. It can be used to automate the process of testing an iOS app by simulating user interactions and then verifying that the app functions as expected.

I haven't used it yet, but it seems detox is a fine e2e testing tool for react native. something like cypress in the web. I think it's a little hard to configure, but in the end, it's really helpful.

The standard is React Native Testing Library for unit and integration tests, and Detox for E2E tests.

We also improved our React Native support by adding the possibility to generate a Detox config for Expo applications.

Copy & paste the content of the equivalent file from the detox example app for RN, into it. Don't forget to change the package name to your project's package name.

Detox is great for React Native: https://wix.github.io/Detox/

\[@RNC/AsyncStorage\]: NativeModule: AsyncStorage is null. To fix this issue try these steps: • Rebuild and restart the app. • Run the packager with \`--reset-cache\` flag. • If you are using CocoaPods on iOS, run \`pod install\` in the \`ios\` directory and then rebuild and re-run the app. • If this happens while testing with Jest, check out docs how to integrate AsyncStorage with it: https://react-native-async-storage.github.io/async-storage/docs/advanced/jest If none of these fix the issue, please open an issue on the Github repository: https://github.com/react-native-async-storage/async-storage/issues 5 | import { ReactQueryDevtools } from '@tanstack/react-query-devtools'; 6 | import { Platform } from 'react-native'; > 7 | import AsyncStorage from '@react-native-async-storage/async-storage';

Storage: redux-persist, @react-native-async-storage/async-storage

You want this: react-native-async-storage

What do you mean by local storage? The browser based localStorage API does not exist by default in react-native. There is an analogue though... The most basic package that most people use, AsyncStorage is just a string based key-value store: https://github.com/react-native-async-storage/async-storage . It's very useful for anything simple. It also has a merge function which lets you automatically update stringified JSON objects without unpacking them and doing the modifications yourself.

Since the original React Native AsyncStorage was deprecated, you may be using the community solution: react-native-async-storage. I would personally recommend it!

I think that you using a deprecated package to store your state. Verify if you are using https://github.com/react-native-async-storage/async-storage.

State management, orchestrating HTTP requests, synchronizing client and server state: all these things will apply to React Native. The differences will only arise when the device layer comes into play (for example, if you have to store data on the client, window.localStorage doesn’t exist, but AsyncStorage does.)
