在 Redux 的编写测试部分,http:store.dispatch(actions.fetchTodos())
//rackt.org/redux/docs/recipes/WritingTests.html,如果 store.dispatch 确实在调用 actions.fetchTodos ,如何不调用 fetch 方法?
it('creates FETCH_TODOS_SUCCESS when fetching todos has been done', (done) => {
nock('http://example.com/')
.get('/todos')
.reply(200, { todos: ['do something'] })
const expectedActions = [
{ type: types.FETCH_TODOS_REQUEST },
{ type: types.FETCH_TODOS_SUCCESS, body: { todos: ['do something'] } }
]
const store = mockStore({ todos: [] }, expectedActions, done)
store.dispatch(actions.fetchTodos())
})
每次我尝试运行类似的东西时,我总是得到一个未定义的提取。即使我使用诺克。所以我必须监视我的行为,以免接到获取电话。
这是我的单元测试:
it('should request a password reset, and then return success on 200', (done) => {
nock('http://localhost:8080/')
.post('/password-reset-requests')
.reply(200);
var email = "test@email.com";
const expectedActions=[
{type: REQUEST_ADD_PASSWORD_RESET_REQUEST},
{type: REQUEST_ADD_PASSWORD_RESET_REQUEST_SUCCESS}
];
const store = mockStore({}, expectedActions, done);
store.dispatch(Actions.addPasswordResetRequest());
这是行动:
export default function addPasswordResetRequest(email){
return dispatch => {
dispatch(requestAddPasswordResetRequest(email));
return addPasswordResetRequestAPI(email)
.then(() =>{
dispatch(requestAddPasswordResetRequestSuccess());
})
.catch((error) => {
dispatch(requestAddPasswordResetRequestFailure(error));
});
};
}
以及调用 fetch 的函数:
export const addPasswordResetRequestAPI = (email) => {
return fetch(
SETTINGS.API_ROOT + '/password-reset-requests',
{
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
email: email,
code: NC_SETTINGS.GROUP.code
})
}
)
.then(handleResponse);
};
我不确定我正在做的方式是否足以仅用于测试操作,但是我确实遇到了 store.dispatch 的问题,它只返回了 expectedActions 的第一个元素,并且它不等于我的列表在间谍 addPasswordResetRequest 中提供。下面包括间谍行动。
it('should request a password reset, and then return success on 200', (done) => {
nock('http://localhost:8080/')
.post('/password-reset-requests')
.reply(200);
Actions.addPasswordResetRequest = spy(() => {
return ([
{type: REQUEST_ADD_PASSWORD_RESET_REQUEST},
{type: REQUEST_ADD_PASSWORD_RESET_REQUEST_SUCCESS}
]
);
});
var email = "test@email.com";
const expectedActions=[
{type: REQUEST_ADD_PASSWORD_RESET_REQUEST},
{type: REQUEST_ADD_PASSWORD_RESET_REQUEST_SUCCESS}
];
const store = mockStore({}, expectedActions, done);
store.dispatch(Actions.addPasswordResetRequest());
