间谍没有呼吁采取行动

Question

我试图将一个组件渲染到Mocha中，并且我不知道为什么会出现此错误：

任何人都知道为什么会这样？我手动传递道具，因为当自己包装自己的容器时，Enzyme并没有真正覆盖connect（）。

import chai from 'chai'
import React from 'react'
import { shallow, props } from 'enzyme'
import sinon from 'sinon'
import PureTestNest from '../../components/CounterNest'
import thunk from 'redux-thunk';
import configureStore from 'redux-mock-store'
import sinonChai from 'sinon-chai'


const expect = chai.expect;
chai.use(sinonChai);


function setup(value = 0) {
  const component = shallow(
    <PureTestNest value={value} doIncreaseNumber={doIncreaseNumber} store={store} />
  )
  let doIncreaseNumber =  sinon.spy()

  return {
    component: component,
    doIncreaseNumber,
    buttons: component.find('button')
  }
}

const middlewares = [thunk]
let mockStore = configureStore(middlewares)
let component;
const getState = {}
const store = mockStore(getState)

describe('Components --CounterNest', () => {

  it('should increment an value on a click', () => {
    const { buttons, doIncreaseNumber } = setup()
    buttons.at(0).simulate('click')
    expect(doIncreaseNumber).to.have.been.called()
  });

});

在组件中使用间谍之前创建间谍？

function setup(value = 0) {
  let doIncreaseNumber =  sinon.spy()

  const component = shallow(
    <PureTestNest value={value} doIncreaseNumber={doIncreaseNumber} store={store} />
  )

  return {
    component: component,
    doIncreaseNumber,
    buttons: component.find('button')
  }
}

我不熟悉Mocha（Jasmine用户）
