[英]How to test post calls in axios with jest and axios-mock-adapter
i have this action that i have to test 我有这个动作我必须测试
export function addContractorToJob(values) {
return dispatch => {
axios.post(`${API_URL}add-contractor`, values)
.then((job) => {
if(job) {
dispatch(sendSuccessMessage(ADD_CONTRACTOR, "You have successfully applied for this job."));
}
});
}
} }
its using thunk to dispatch an action when i receive a conformation of a contractor being added to the database through an api. 当我收到通过api添加到数据库的承包商的构想时,使用thunk调度操作。
this is what i have tryed so far but it always says that i cannot Cannot read property 'then' of undefined but this is how i have been testing many of my other dispatches that are not using thunk. 到目前为止,这是我一直尝试的结果,但它总是说我无法读取未定义的属性“ then”,但这就是我一直在测试许多其他未使用thunk的调度的方式。
const middlewares = [thunk];
const mockStore = configureStore(middlewares);
const mock = new MockAdapter(axios);
it('should call success message action on successfully adding contractor to job', () => {
mock.onPost(`${actions.API_URL}add-contractor`).reply(200,
[{id: 123, jobTitle: 'the job title'}]);
const store = mockStore();
store.dispatch(actions.addContractorToJob(1001)).then(() => {
expect(store.getActions()[0].type).toEqual(actions.ADD_CONTRACTOR);
expect(store.getActions()[0].payload).toEqual("You have successfully applied for this job.");
});
});
does anyone have any idea where i am going wrong at all? 有谁知道我哪里出错了?
try returning the promise from your Axios.post call which will return it back through the instantiating call: 尝试从您的Axios.post调用返回诺言,该诺言将通过实例化调用返回:
return dispatch => {
return axios.post(`${API_URL}add-contractor`, values)
.then((job) => {
