Detox VS react-native-circleci-orb

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.

I mostly started with the RN community orb (https://github.com/react-native-community/react-native-circleci-orb), then bolted on the fastlane process later. One thing worth changing is that CircleCI now has an Android machine image that can run the emulator (https://discuss.circleci.com/t/early-preview-new-android-machine-image/39016). Since it's based on the Linux image, it's much cheaper than the MacOS insurance. Fastlane has a lot of documentation, so it's mostly a matter of seeing up the lanes to build the right versions. And definitely do the match based codesigning repo they suggest for the iOS side.

Add this to your /app/build.gradle since we are going to use the react-native-circleci-orb.
