Feature Request: reuse the same snapshot in multiple places

[andykais]

I have a use case like so:

it('should make sure the return value doesnt change', async () => {
  const resultPre = getResult()
  expect(resultPre).to.matchSnapshot()
  await runSomeSideEffect()
  const resultPost = getResult()
  expect(resultPost).to.matchSnapshot()
})

exports['should make sure the return value doesnt change 1'] = ...
exports['should make sure the return value doesnt change 2'] = ...

This works fine by ensuring that the snapshots do not change, but it duplicates what is the same output and gives a slightly misleading error if it fails.

It would be great if there was a way to specify reusing the same snapshot in different places. For example:

import { createSnapshotKey } from 'chai-jest-snapshot'
const snapshotKey = createShapshotKey()

it('should make sure the return value doesnt change', () => {
  ...
  expect(resultPre).to.matchSnapshot(snapshotKey)
  ...
  expect(resultPost).to.matchSnapshot(snapshotKey)
  // both reference exports['should make sure the return value doesnt change 1']=...
})

arg wait! I found an obvious solution

it('should make sure the return value doesnt change', async () => {
  const resultPre = getResult()
  expect(resultPre).to.matchSnapshot()
  await runSomeSideEffect()
  const resultPost = getResult()
  expect(resultPost).to.deep.equal(resultPre)
})

Im closing this now, but feel free to open it again if there is anything else to discuss
