录制的传奇再次变空

Question

我正在使用recordSaga测试模式来测试我的Sagas：

recordSaga.js

import { runSaga } from "redux-saga";
export default async function recordSaga(saga, initialAction) {
  const dispatched = [];

  await runSaga(
    {
      dispatch: action => {
        dispatched.push(action);
        console.log(dispatched);
      }
    },
    saga,
    initialAction
  ).done;
  console.log(dispatched);

  return dispatched;
}

dealAction.test.js

describe("getDealsSaga", () => {
    it("dispatches a success action with the fetched deals", async () => {
      const dispatched = await recordSaga(getDealsSaga, startAction);
      console.log(dispatched);

      expect(dispatched).toContainEqual(successAction);
    });
  });

dealActions.js

export function* getDealsSaga(): Saga<void> {
  try {
    const rawDeals: Object[] = yield call(getDealsApi);
    const deals: Deal[] = rawDeals.map(p => Deal.fromApi(p));
    console.log("getDealsSaga", deals.length, "deals");
    yield put({ type: "GET_DEALS_SUCCESS", deals });
  } catch (error) {
    console.log("getDealsSaga", "error:", error);
    yield put({ type: "GET_DEALS_FAILURE", error });
  }
}

export default function* dealSaga(): Saga<void> {
  yield all([yield takeEvery("GET_DEALS_START", getDealsSaga)]);
}

测试失败，收到一个空数组。但是，传奇中的以及recordSaga 中的日志语句确认传奇正在运行，并且recordSaga中的回调也正在工作。

    console.log recordSaga.js:15
      []
    console.log __tests__/dealActions.test.js:46
      []
    console.log src/redux/actions/dealActions.js:27
      getDealsSaga 10 deals
    console.log recordSaga.js:9
      [ { type: 'GET_DEALS_SUCCESS',
          deals:
           [ [Deal],
             [Deal],
             [Deal],
             [Deal],
             [Deal],
             [Deal],
             [Deal],
             [Deal],
             [Deal],
             [Deal] ] } ]

日志的顺序表示recordSaga或测试中的异步性有问题。

我很困惑，因为我已经将此模式与确切的代码（相同的recordSaga文件，saga / actions / tests，除了其数据详细信息相同）一起用于其他几个项目中，并且从来没有这个问题。
