Question

我正在测试以下saga函数

export function* fetchMessages(channel) {
    yield put(requestMessages())
    const channel_name = channel.payload
    try {
        const response = yield call(fetch,'/api/messages/'+channel_name)

        if(response.ok){
            const res = yield response.json();

            const date = moment().format('lll');
            yield put(receiveMessages(res,channel.payload,date))
        }


    } catch (error){
        yield put(rejectMessages(error))
    }
}

这些是我对第3和第4产量的测试：

const gen = onFetchMessages(fetchMessages(channel))
////where export const fetchMessages = createAction(LOAD_MESSAGES);
const channel = "channel 9"
const response = []

    assert.deepEqual(
        gen.next(response).value,
        response.json,
        'should convert response to json'
    )

    const date = Date.now();
    assert.deepEqual(
        gen.next(response,channel,date).value,
        put(receiveMessages(response,channel,date)),
        'should dispatch LOAD_MESSAGES_SUCCESS with payloads of response, channel and date'
    )

实际返回undefined，即gen.next（响应，通道，日期）.value返回undefined。你能告诉我正确的测试方法吗？感谢

不太确定您的代码尝试做什么。对此功能的正确测试可能如下所示：

SELECT A.EMPLOYEE, A.PHONE AS CELL, B.PHONE AS OFFICE, C.PHONE AS HOME
FROM PHONE_NUMBERS A, PHONE_NUMBERS B, PHONE_NUMBERS C
WHERE A.EMP_NUM = B.EMP_NUM
AND A.EMP_NUM = C.EMP_NUM
AND A.PHONE_TYPE = 'CELL' (+)
AND B.PHONE_TYPE = 'OFFICE' (+)
AND C.PHONE_TYPE = 'HOME' (+)

为redux-saga编写测试
