我正在使用Express.js应用程序。目前的功能是创建与发布请求的约会，并从第三方API获取和保存数据，然后在后续请求中发送更新的API数据。该功能完全正常，但在测试中，获取API数据的功能没有被调用。摩卡测试中没有调用函数
路线创建约会：
app.post('/schedule', requestHandler.postSchedule);
创建约会请求处理程序：
requestHandler.postSchedule = function (req, res) {
let appointment = {
// posted data
};
new Appointment(appointment)
.save()
.then(newAppointment => {
if(req.body.cityName && req.body.cityName !== '') {
console.log('req.body.cityName', req.body.cityName);
weatherHelper.addNewCityWeatherData(req.body.cityName);
}
return newAppointment;
})
.then(newAppointment => {
// do some other stuff
res.send(newAppointment);
})
.catch(err => {
error(err);
});
};
功能添加天气数据：
exports.addNewCityWeatherData = (city) => {
console.log('City in addNewCityWeatherData', city);
getCurrentTrackingCities(cities => {
if(cities.indexOf(city) < 0) {
console.log(city + ' data not in weather');
getWeatherData(city, data => {
console.log('Got weather data');
addWeatherDataToDB(city, data);
});
} else {
console.log('City exists');
}
});
};
函数来获取从API气象数据：
getWeatherData = (city, callback) => {
console.log('getWeatherData called', city);
let url = `http://api.apixu.com/v1/forecast.json?key=${weatherApiKey}&q=${city}&days=${10}`
request(url, (err, res, body) => {
console.log('Weather data received body');
callback(body);
});
};
测试时，此功能失败，除了'天气数据收到正文'以及所有功能的日志外，所有控制台日志都会打印。
这里是我的测试：
describe.only('Weather data', function() {
let requestWithSession = request.defaults({jar: true});
let hashedPass = bcrypt.hashSync('testpass', null);
beforeEach((done) => {
new User({
'name': 'Test User',
'email': '[email protected]',
'password': hashedPass
})
.save()
.then(() => {
let options = {
'method': 'POST',
'uri': testHost + '/login',
'form': {
'email': '[email protected]',
'password': 'testpass'
}
};
requestWithSession(options, (err, res, body) => {
done();
});
});
}); // beforeEach
afterEach((done) => {
// remove test stuff from db
}); // afterEach
it('Adds weather data when an appointment with new city is posted', (done) => {
let options = {
'method': 'POST',
'uri': testHost + '/schedule',
'form': {
'title': 'Test title',
'description': 'Test description',
'start_date_time': '2017-07-19 01:00',
'end_date_time': '2017-07-19 02:00',
'cityName': 'New York',
'isTrackingWeather': 'true'
}
};
// post request to add appointment data
requestWithSession(options, (err, res, body) => {
if(err) {
console.log('DatabaseError in Weather Data');
throw {
type: 'DatabaseError',
message: 'Failed to create test setup data'
};
}
let options = {
'method': 'GET',
'uri': testHost + '/allweather'
};
// subsequesnt request to get updated weather data
requestWithSession(options, (err, res, body) => {
let found = false;
weatherData = JSON.parse(body);
// console.log('weatherData in test', weatherData);
weatherData.forEach(weather => {
if(weather.location && weather.location.name === 'New York') {
found = true;
}
});
expect(found).to.be.true;
done();
});
});
});
}); // Weather Data
这里是终端输出：
谁能请告诉我，我究竟做错了什么？
