Could we add an option that names / detects files as equivalent when they were run from .ts and transpiled .js?

Thanks for all your work! It works really well. Just a small feature request that someone or me later could pick up and add, as right now if I run a test from a ts file and run the same test from the transpiled js it doesn't recognize the snapshots but creates 2 different snapshot files.

Could be implemented as an option, or maybe even just as the default (if two files differed only in the 1 letter (j vs t in the extension), could also be added for tsx and js I guess, though if default it would be a breaking change

@emilgoldsmith I think by default we could choose to strip the file extension from the filename, for example:
example.spec.ts -> __snapshots__/example.spec.js
example.spec.js -> __snapshots__/example.spec.js
example.spec.jsx -> __snapshots__/example.spec.js

maybe this is suggested somewhere else already however.

As a temporary solution for you, you should be able to do this to modify the filename on the mocha context object. The following will remove the extension from the filename that snapshot reads

beforeEach(function(){
  this.currentTest.file = this.currentTest.file.split('.').slice(0, -1).join('.')
})
