Test redux-observable epics with ease.

"I've written unit tests for my redux-observable epic(s) and have a lot of test boilerplate. How can I reduce this barrier-to-test?"

expectEpic(
  epic: (action$: Observable<any>, store: ReduxStore) => Observable<any>,
  condition$: Observable,
  expect$: Observable,
  assert: (a: any, b: any) => ?boolean,
  done: () => ?any,
  store: ReduxStore
)

• epic: The redux-observable 'epic' function you would like to test.
• condition$: The input actions for the test case.
• expect$: The stream of actions to be compared with the stream returned from epic.
• assert: A function which compares actions from the epic with the contents of expect$
• done: Completion callback (usually provided by your test runner).
• store: (Optional) A redux store, will be needed if your epic consumes data from the store.

import expectEpic from 'redux-observable-expect'

expectEpic(
  myAwesomeEpic
  of({ type: TRIGGER_TYPE }),
  of(
    { type: EXPECTED_TYPE },
    { type: ANOTHER_EXPECTED_TYPE }
    ),
  (a, b) => expect(a).toEqual(b),
  done
)
