Question

我有这样的动作：

export const loadPositions = (accountId, filter) => dispatch => {
  dispatch({ type: ActionTypes.SEARCH_RESULTS_PENDING });

  return ServiceManager.call(someUrl, {
    method: 'GET',
  })
    .then(({ _embedded: { positions } }) => {
      dispatch(updatePositions(positions));
      dispatch(filterPositions(filter));
    })
};

并测试：

it('should filter positions giving no results', () => {
  return store.dispatch(loadPositions(accountId, filter)).then(() => {
    const filterAction = findActionByType(store.getActions(), ActionTypes.SEARCH_RESULTS_UPDATED);
    const {
      payload: { instruments },
    } = filterAction;

    expect(instruments).toEqual([]);
  });
});

我正在使用import configureMockStore from 'redux-mock-store';

进行测试

问题在于，正在调度filterPositions的{{1}}从以下调用开始：

SEARCH_RESULT_UPDATED

这取决于应该由export const filterPositions = filter => (dispatch, getState) => { const positions = selectors.getPositions(getState()); ... }动作（特别是一个减速器，侦听此动作创建者分配的动作）预先设置的状态。

如何对此进行测试？我猜不可能将reducer插入模拟存储吗？
