Question

在我的传奇中，我有以下代码：

export function* removeProfile(auth, database, action){
try{  
    const url = `/users/${action.user.uid}` 

    const {ref} = database
    const result = yield call([database, ref], url)
    const {remove} = database.ref()  
    yield call([result, remove])      

    const deleteFunction = () => action.user.delete()
    yield call([action.user, deleteFunction])

    //yield action.user.delete() && database.ref(url).remove()
    yield put(ActionCreator.removeProfileSuccess()) 
    yield destroyAuth(auth)  
}catch({message}){
     yield put(ActionCreator.removeProfileFailure(message))      
}     
}

在我的测试中，我有这个：

describe('should test removeProfile', () => {
const actionMock = {
    user: {
        uid: undefined,
        delete : jest.fn()
    }
}
const deleteFunction = () => actionMock.user.delete()
const url = `/users/${actionMock.user.uid}`

const databaseMock = {
    ref: jest.fn()
}
const {ref} = databaseMock
const removeFunction = () => databaseMock.ref

const authMock = {
    delete: jest.fn()
}

const it = sagaHelper(removeProfile(authMock, databaseMock, actionMock))
it('should call api ref and remove from database', result => {
    let newResult = ''
    expect(result).toEqual(newResult = call([databaseMock, ref], url))
    expect(newResult).toEqual(call([newResult, removeFunction]))
})
it('should call api delete user from authentication', result => {
    expect(JSON.stringify(result)).toEqual(JSON.stringify(call([actionMock.user, deleteFunction]))) 
})  
it('should put removeProfileSuccess', result => {
    expect(result).toEqual(put(ActionCreator.removeProfileSuccess()))
}) 
})

我需要在测试的let newResult = ''中取一个值，并传递给其他等号以完成测试，“应该调用api ref并从数据库中删除”。但是我的方法却行不通。如何将期望值的结果传递给使用此值进行新呼叫的另一个呼叫？ let newResult = '' expect(result).toEqual(newResult = call([databaseMock, ref], url)) expect(newResult).toEqual(call([newResult, removeFunction]))

我需要在另一个中使用一个Expect（）。equal（）的返回值
