redux-observable-apollo-mock

Easier testing for redux-observable epics that depend on apollo-client.

When to use this

• Your project uses Apollo Client for managing component GraphQL queries.
• Your project makes use of redux-observable epics.
• You are tired of the boilerplate when testing epics that depend on Apollo data.

Installation

npm i redux-observable-apollo-mock --dev

Usage

import setupReduxApolloStore from "redux-observable-apollo-mock";

import transactionEpic from "./transactionEpic";

/* Import your schema type definitions. Can be all concatenated
types combined with `concatenateTypeDefs()` as well. */
import { typeDefinitions } from "../server/graphql/schema";

import {
  BEGIN_CANCEL_TRANSACTION,
  END_CANCEL_TRANSACTION,
  CLOSE_TRANSACTION_WINDOW
} from "../actions/transaction";

const createStore = (initialState, apolloMocks) =>
  setupReduxApolloStore(
    typeDefinitions,
    transactionEpic,
    initialState,
    apolloMocks
  );

describe("transactionEpic", async () => {
  it("should cancel a transaction", async () => {
    const store = createStore({}, {});

    store.dispatch({ type: BEGIN_CANCEL_TRANSACTION });

    await store.expectActionToBeDispatched(CLOSE_TRANSACTION_WINDOW);

    expect(store.getActions()).toEqual([
      { type: BEGIN_CANCEL_TRANSACTION },
      { type: END_CANCEL_TRANSACTION },
      { type: CLOSE_TRANSACTION_WINDOW }
    ]);
  });
});
