flipper VS appium

Definitely switch to VS Code! I personally don't use the built in VS Code debugger, but check out Flipper as another option. It's got a lot of great tools and plugins for debugging. The Layout Inspector will be what you are looking for if you want to inspect the styling specifically.

I use Flipper with its Layout Inspector plugin

Also no folder show on sources filesystem (in Hermes Debugger) as described here: https://github.com/facebook/flipper/issues/4530

Very useful and beautiful and simply , my suggestion is to use this Flipper

You may also want to look into custom Flipper plugins to instrument your app.

Some development tools for the web are similar (Chrome debugger, mostly) to those for React Native, but other aspects are very different (working with the metro bundler, using Flipper, AsyncStorage debugging, more). Some techniques developers will use are the same (breakpoints and console logging), but others are different (knowing when to restart the packager vs reinstall the app on device).

from the GitHub, and has existed under the name flipper since mid 2018

It's not possible to use a browser to debug a JSI app, use Flipper (for android Flipper also has SQLite Database explorer).

Try to debug it with adb logcat or Android Studio or Flipper you'll find the error why is crashing :)

TestUI combines 2 different paradigm test automation frameworks, i.e., mobile (Appium) and desktop (Selenide), into one neat framework. In our opinion, it’s a great framework that offers vast functionality with easy-to-learn syntax, not to mention full access to Selenide methods in case something tricky needs to be done.

Feel free to look at the lerna/npm config: https://github.com/appium/appium

espresso is Google's general recommendation, but there are other tools out there that exist like appium or kaspresso. Sure there are more, just goigle it to see what else there is.

Appium exists from that Selenium family. That will do the job. https://appium.io/

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.

With iOS app testing, we test our iOS application on mobile devices (emulators or real devices, depending on the use case). Here, we pass it through various testing phases to ensure that the final version has minimum or no bugs. These can include manually inspecting the application like an end-user or running an automation framework like Appium or Testsigma.
