Disabling cache in testing or clearing the cache between tests?

[NullVoxPopuli]

I ran in to an issue between tests when I upgraded today (to beta.4), where having the cache no by default (previous version I was using didn't have cache), records were mistakenly being kept between tests.

I have this at the moment

import localforage from 'localforage';

async function cleanEverything() {
  // specifically, offline storage
  await localforage.clear();
  await localStorage.clear();
}

export function clearLocalStorage(hooks: NestedHooks) {
  hooks.beforeEach(async function() {
    await cleanEverything();
  });

  hooks.afterEach(async function() {
    await cleanEverything();
  });
}

with

export default LFAdapter.extend({
  namespace: 'emberclear',
  caching: 'none',
  // ...

and that gets all my tests passing! :tada:

but for having cache, (cause I assume this would make overall app usage slightly quicker?), I need a way to clear the cache between tests such that the same behavior as my cleanEverything function will still work -- is there a way to do this? (or is this a coming feature?)

The way I did it yesterday.

1. call setupTest(hooks).
2. in each test, lookup the adapter in the container.
3. in each test, clear the cache.

Maybe wrap in a function.
