如何在redux中有条件地分派/级联操作

当然 可能的 要通过重击实现此功能:

export const dragOverAction = function(payload: DragOverActionPayload) {
  return function(dispatch: Dispatch, getState: () => GlobalStateTree) {
      // Various business logic
      if (someCondition) {
        return;
      }

      if (anotherCondition) {
        dispatch(doSomething({
          <snip>
        }));
      } else if (anotherCondition) {
        dispatch(doSomethingElse({
          <snip>       
        }));
      }

      // Otherwise, don't dispatch anything.
  }
}

测试并没有我预想的那么糟糕:

import configureMockStore from "redux-mock-store";
import thunk from "redux-thunk";

export const mockStore = configureMockStore([thunk]); 
import * as allActions from "../app/actions/index";

describe("dragOverAction", function() {
    it("should <blah blah>", async function() {
        let store = mockStore();
        await store.dispatch<any>(allActions.dragOverAction({
            foo: bar,
            <snip>
        }));
        const actions = store.getActions();

        expect(actions).toBe(<snip>);
    });
});
