Snapshot testing differences between local machine and Xcode Cloud

Hi,

I’m using the snapshot testing library from https://github.com/pointfreeco/swift-snapshot-testing

I recorded the snapshot tests on the iPhone 15 pro simulator on iOS 17.4 and Xcode 15.3 On my M1 Max MacBook Pro

Within the tests found in https://github.com/fespinoza/sample-json-app/blob/84b81ee3fa1d24e97bbeded65487b32258a42325/SampleProjectTests/MovieDetails/MovieDetailsViewTests.swift

I try to control all the traits and properties I can, to make sure the test is run in the same environment in Xcode Cloud

For some reason though, on Xcode Cloud, Text with multiline strings have a different line height than on my machine and thus the test fail

I don’t understand:

  • why that happens
  • how to debug this situation

Does anyone here have any pointers?

from Xcode Cloud

P.S. thread initially posted in https://github.com/pointfreeco/swift-snapshot-testing/discussions/842 but i haven’t gotten any answers, trying here instead

Did you compare the supported languages between your local simulator and CI simulator? The line height increases when you add a language like Hindi or Arabic as a supported language.

Which reminded me that I hadn't set up a test plan for the project. A test plan is one way to configure the language/region of the the app, which I set the same as I had locally on my machine, then, with this configuration, the test passed as expected
