React Native 0.47.2 timeout issues

[SMJ93]

Description

We spiked detox a couple of months ago on:

• React Native: 0.45
• Detox: 5.3.0
• Jest: 20.0.4

Everything worked as expected.

We have now upgraded to React Native 0.47.2, but detox doesn't seem to be working. We have followed the getting started guide multiple times with different versions of detox with both mocha and jest:

5.6.0+ hangs on the white screen - this is a known issue

< 5.5.1 throws a timeout error - The app launches on the simulator as expected, but then hangs until the tests time out in both Release and Debug mode:

** BUILD SUCCEEDED **

Steps to Reproduce

• Create a react native project version 0.47.2
• Install and run detox using the getting started guide

Node, Device, Xcode and macOS Versions

• Node: 8.1.0
• Device: iPhone 6 iOS 10.3
• Xcode: 8.3.3
• macOS: 10.12.6

Any help would be greatly appreciated. We have spent days trying to debug this, but keep going round in circles.

React Native changed implementation to the C++ bridge in 0.45, and synchronization broke. We fixed that in 5.6.1. So using a modern (0.45.0+) RN with an old build is not supported. I will close this issue as it cannot be meaningfully debugged. Instead, we should focus on fixing #155.

[LeoNatan]

Hm, I'm actually mistaken. The improvement was done in 5.2.0.
I have not tested yet Detox with 0.47.2, so there may have been introduced new issues. Let's keep the issue open.

[heuism]

I guess the app is terminated like what i have ran into and refers to #279 as well

[LeoNatan]

@Kureev If you enable synchronization debug, what do you see?

[Kureev]

@LeoNatan sure thing, I can take care if you elaborate what "synchronization debug" means :)

[SMJ93]

I think this is related to issue #270 so I will close for the time being.
