Make the placement of the snapshot directory configurable via a single entry point

[saren-tech]

My problem
I have a project with around ~100 modules, many of these modules have a test target that takes snapshots.
These tests are in folders eg:
root/logic/ManagerSpec.swift
Which results in the snapshots being recorded in
root/logic/__snapshots__/ManagerSpec/.....png

If these files are not ignored Xcode generates warnings like

found 21 file(s) which are unhandled; explicitly declare them as resources or exclude from the target

However excluding every nested snapshot directory is a lot of 'effort' and if for some reason test are removed, renamed, moved then you also have to update the package file which is additional manual labor.
Since the package file does not seem to support pattern matching like cocoapods we sadly cannot do

exclude: ["/**/__snapshots__"]

(or please correct me if I am wrong).

Solutions?
So my question would be does anyone here have a nice solution for this?

Some ideas of mine

• place it all in the root folder: root/__snapshots__/[all files]
• don't flatten the directory structure but inserts __snapshots__ in between like: root/__snapshots__/logic/ManagerSpec/...
• Any other ideas?

Changing this in the library would break current tests so if something like this would be implemented (would still prefer a pattern ignore) we could introduce a enum like SnapshotDirectoryStrategy and have it configurable like public var isRecording = false

The enum could then be something like

public enum SnapshotDirectoryStrategy {
  case nextToTests // current value
  case flatRoot
  case root
  case custom((...) -> URL)
}
