Stylistically i'd prefer moving this function out of diffImageToSnapshot and renaming to something like writeFileWithHooks and have it take runtimeHooksPath as a third argument. that way it more clearly differentiates the custom writeFileSync from fs.writeFileSync
as an example:
| const writeFileSync = (pathToFile, content) => { | |
| const writeFileWithHooks = (pathToFile, content, runtimeHooksPath) => { |

I won't have time to do this modification right now, but I'll do it in the next few days!
Thanks for the review 🙇♂️

FYI: I'd need 5 arguments as testPath & currentTestName are also used inside of this writeFileSync

Description
Add a new top level option
runtimeHooksPaththat contains a potential path to a JS file.This file can contain multiple hooks when
diffSnapshotis called, likeonBeforeWriteToDiscPath(to be able to inject EXIF data to PNGs without building this feature into this library).The reason why I exposed that via a path to a JS file instead of exposing a function, is because
diffSnapshotis sometimes called from a worker, and we cannot serialize properly functions.For now there is only
onBeforeWriteToDiscPathbut I made that generic enough to be able to add more features to it in the future.Motivation and Context
Fixes: #332
