Compatibility with React Native New Architecture

[JulienLeal]

Hi team,

I would like to confirm Maestro's compatibility with React Native's New Architecture (Fabric and TurboModules). As React Native evolves, tools like Detox have had some challenges with supporting the New Architecture fully.

• Does Maestro officially support React Native's New Architecture?
• Are there any known limitations or issues when testing apps that are built with Fabric and TurboModules enabled?

I couldn't find specific details in the documentation about this, and I want to ensure a smooth integration for my project.

Thank you in advance for your time and for building such a great tool!

MA-2807 Compatibility with React Native New Architecture

There's nothing in New Architecture that should prevent Maestro from working - Maestro is implementation agnostic. So long as it's still 'accessible' (in both the technical and a11y meanings) then I'd expect it to work.

I'd also expect that given how long New Architecture has been kicking around that we'd have seen a lot of complaints by now if it weren't working.

Reopening this, given some info from Slack that implies that this could end up as a bug rather than a question.

Me:

I don't believe the RN architecture is relevant to Maestro. There's no special code to deal with RN, Flutter, Kotlin MP, etc. It's all just UI components once they're rendered.

Brett:

Normally I would agree. I have run it successfully on the new arch, but the test app was pretty small. I guess the reason they are asking is because RN moved from natively rendering inputs etc, to I think with Fabric using a pixel rendering system like Flutter used to do too.

This could really use someone pointing at an example app in the New Architecture that would help us know one way or another.

@Fishbowler awesome, thanks to give more context about the internal discussion.
To bring more for this, I also saw that react native is using maestro for their first e2e tests and as you can see on the source code, they're validating the new react architecture with maestro tests
