[BUG] measure code is running under incorrect Node.js configuration

See original GitHub issue

I’m getting this message when running yarn reassure:

console.error ❌ Reassure: measure code is running under incorrect Node.js configuration. Performance test code should be run in Jest with certain Node.js flags to increase measurements stability. Make sure you use the Reassure CLI and run it using “reassure” command.

Same with npx reassure or yarn node --expose_gc $(yarn bin reassure).

reassure: v0.4.1 node: v14.17.6 yarn: v1.22.19 jest: v26.6.3 MBP M1 macOS: v12.4

Removing jest-expo and setting preset: react-native worked 🎉 The test was very slow though (200s)

What if you replaced jest-expo preset with react-native? Would be great if you tried running our examples and see if there’s anything in your environment that gets in the way
