Matchers

toHaveStored

import { Storage } from '@universal-packages/storage'

import config from './config'

it('should store file', async () => {
  const storage = new Storage(config)

  await storage.store({ name: 'file.png', data: buffer })

  expect(storage).toHaveStored('./path/to/file.png')

  // Or against the Storage class
  expect(Storage).toHaveStored('./path/to/file.png')
})

toHaveStoredVersion

import { Storage } from '@universal-packages/storage'

import config from './config'

it('should store file', async () => {
  const storage = new Storage(config)

  const key = await storage.store({ name: 'file.png', data: buffer })
  await storage.storeVersion(key, { width: 100, height: 100 })

  expect(storage).toHaveStoredVersion('./path/to/file.png', { width: 100, height: 100 })

  // Or against the Storage class
  expect(Storage).toHaveStoredVersion('./path/to/file.png', { width: 100, height: 100 })
})

toHaveDisposed

import { Storage } from '@universal-packages/storage'

import config from './config'

it('should dispose file', async () => {
  const storage = new Storage(config)

  const key = await storage.store({ name: 'file.png', data: buffer })

  await storage.dispose(key)

  expect(storage).toHaveDisposed(key)

  // Or against the Storage class
  expect(Storage).toHaveDisposed(key)
})

toHaveDisposedVersion

import { Storage } from '@universal-packages/storage'

import config from './config'

it('should dispose file', async () => {
  const storage = new Storage(config)

  const key = await storage.store({ name: 'file.png', data: buffer })
  await storage.storeVersion(key, { width: 100, height: 100 })

  await storage.disposeVersion(key, { width: 100, height: 100 })

  expect(storage).toHaveDisposedVersion(key, { width: 100, height: 100 })

  // Or against the Storage class
  expect(Storage).toHaveDisposedVersion(key, { width: 100, height: 100 })
})

Typescript

In order for typescript to see the global types you need to reference the types somewhere in your project, normally ./src/globals.d.ts.

/// <reference types="@universal-packages/storage-jest" />

This library is developed in TypeScript and shipped fully typed.
