javascript - Function not getting called in Mocha test -


i working on express.js app. current feature creating appointment post request , getting , saving data third party api, sending updated api data in subsequent request. feature working in test, function api data not getting called.

route create appointment:

app.post('/schedule', requesthandler.postschedule);

the request handler creating appointment:

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 => {       // other stuff       res.send(newappointment);     })     .catch(err => {       error(err);     }); };

function add weather data:

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');     }   }); };

function weather data api:

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);   }); };

when testing, feature fails , console logs printed except 'weather data received body' , logs in consequent functions.

here test:

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': 'testuser@test.com',       'password': hashedpass     })     .save()     .then(() => {       let options = {         'method': 'post',         'uri': testhost + '/login',         'form': {           'email': 'testuser@test.com',           'password': 'testpass'         }       };       requestwithsession(options, (err, res, body) => {         done();       });     });   }); // beforeeach    aftereach((done) => {     // remove test stuff db   }); // aftereach    it('adds weather data when appointment new city 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 add appointment data     requestwithsession(options, (err, res, body) => {       if(err) {         console.log('databaseerror in weather data');         throw {           type: 'databaseerror',           message: 'failed create test setup data'         };       }        let options = {         'method': 'get',         'uri': testhost + '/allweather'       };        // subsequesnt request 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

here terminal output:

mocha test

can please tell me doing wrong?

when run test test suite make request test server, , code handles request in test server makes another request host.

you not see 'weather data received body' because request handled test server not waiting request test server makes. addnewcityweatherdata has no callback , not return promise, code calls goes on merry way without waiting complete. should modify allow calling code wait result.

also, i'm not seeing how data request initiated test server folded request comes test suite. may have add code too, unless addweatherdatatodb(city, data); taking care of automatically somehow.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
