I am trying to mock the behaviour from my transaction module in my account_spec. I am finding it difficult. Once, I make a deposit from my account, I have to mock the behaviour for the transaction but I am finding it very hard. My test is currently returning 'Transaction' is not undefined
EDIT:
I have an account module:
function Account(statement = new Statement, transaction = new Transaction){
this._statement = statement
this._transaction = transaction
}
Account.prototype.deposit = function(amount) {
this._transaction.deposit(amount)
this._statement.storeHistory(amount, this._balance, "Deposit")
}
Account.prototype.withdraw = function(amount) {
this._transaction.withdraw(amount)
this._statement.storeHistory(amount, this._balance, "Withdraw")
}
Account.prototype.balance = function() {
return this._balance
}
module.exports = Account;
I have a transaction module:
function Transaction(){
this._balance = 0
}
Transaction.prototype.balance = function() {
return this.balance
}
Transaction.prototype.deposit = function(amount) {
this._balance += amount
}
Transaction.prototype.withdraw = function(amount) {
this._balance -= amount
}
module.exports = Transaction;
My Statement:
function Statement(){
this._logs = []
}
Statement.prototype.seeStatement = function() {
return this._logs
}
Statement.prototype.storeHistory = function(amount, balance, type) {
this._logs.push({amount: amount, balance: balance, type: type})
}
module.exports = Statement;
My Account Spec:
'use strict';
describe('Account',function(){
var account;
beforeEach(function(){
statement = new Statement
var transactionSpy = jasmine.createSpyObj('transaction',['balance','withdraw','deposit']);
account = new Account(statement, transactionSpy);
});
it('is able for a user to deposit', function(){
account.deposit(40)
// expect(account.balance()).toEqual(40)
});
it('is able for a user to withdraw', function() {
account.deposit(40)
account.withdraw(20)
// expect(account.balance()).toEqual(20)
});
it('is able for a user to check their balance', function() {
account.deposit(20)
expect(transaction.balance()).toEqual(20)
});
});
Actually I see typo here, or maybe code is incomplete:
describe('Account', function() {
var account;
var transaction;
var statement = {}; //or some mock object
beforeEach(function() {
var spy = jasmine.createSpyObj('transaction',['returnBalance','withdraw','deposit']);
account = new Account(transaction, statement)
});
it("is able to deposit money", function() {
account.deposit(40)
expect(transaction.returnBalance).toEqual(40)
});
});
The code written by Alexander is correct except one note. You need to pass spy to Account constructor. The name transaction you pass to jasmine.createSpyObj is just a name that will be used in error messages. you can omit it (in this case it will be unknown)
beforeEach(function() {
var transactionSpy = jasmine.createSpyObj('transaction',['returnBalance','withdraw','deposit']);
account = new Account(transactionSpy, statement)
});

I am struggling with the issue of Promise and async/await for last two days. I am trying to configure my protractor.conf.js that would get the browser name just at the starting of the suit and will join with the suit name. I have written jasmine allure reporter code in customized way so that I can get browser name in asynchronously and then use with the suit name. But nothing working properly. In the code I have tried, I get only suit name. Browser name in few seconds later. As a result I could not use that browser name in suit name. Here is my code in detail
Edited
var AllureReporter = function CustomJasmine2AllureReporter(userDefinedConfig, allureReporter) {
let browser = {
getCapabilities: function() {
return new Promise(resolve => {
setTimeout(() => {
resolve({
get: str => str
});
}, 2000);
});
}
};
var result;
let bName = (async () => {
try {
var result = (await browser.getCapabilities()).get('Browser Name');
return result;
} catch (err) {
return "Error or smth"
}
})();
this.suiteStarted = function(suite) {
this.allure.startSuite(suite.fullName + result);
console.log(suite.fullName + result);
};
// other methods like spec done,, spec description.
}
the index code from Allure that can be changed is
'use strict';
var assign = require('object-assign'),
Suite = require('./beans/suite'),
Test = require('./beans/test'),
Step = require('./beans/step'),
Attachment = require('./beans/attachment'),
util = require('./util'),
writer = require('./writer');
function Allure() {
this.suites = [];
this.options = {
targetDir: 'allure-results'
};
}
Allure.prototype.setOptions = function(options) {
assign(this.options, options);
};
Allure.prototype.getCurrentSuite = function() {
return this.suites[0];
};
Allure.prototype.startSuite = function(suiteName, timestamp) {
this.suites.unshift(new Suite(suiteName,timestamp));
};
module.exports = Allure;
and the Suit.js class
function Suite(name, timestamp) {
this.name = name;
this.start = timestamp || Date.now();
this.testcases = [];
}
Suite.prototype.end = function(timestamp) {
this.stop = timestamp || Date.now();
};
Suite.prototype.addTest = function(test) {
this.testcases.push(test);
};
Suite.prototype.toXML = function() {
var result = {
'#': {
'xmlns:ns2' : 'urn:model.allure.qatools.yandex.ru',
start: this.start
},
name: this.name,
title: this.name,
'test-cases': {
'test-case': this.testcases.map(function(testcase) {
return testcase.toXML();
})
}
};
if(this.stop) {
result['#'].stop = this.stop;
}
return result;
};
module.exports = Suite;
I am getting this output after edited the question.the result is undefined in the suit name

I want to get browser name after the the line 'Test Suites & Specs:' and want to add the name with suit name.
The function where you want to use await should be async.
I have made a small example for you. hope it will help
//The function we want to use wait in should be async!
async function myFunction() {
//Using callback
thisTakeSomeTime().then((res) => console.log(res)); //Will fire when time out is done. but continue to the next line
//Using await
let a = await thisTakeSomeTime();
console.log(a);//will fire after waiting. a will be defined with the result.
}
function thisTakeSomeTime() {
return new Promise((res) => {
setTimeout(()=>{res("This is the result of the promise")}, 5000)

I'm currently working on a Alexa Skill for my Smart Home.

I use the "request" module for my http-request, I think you all know this module.
When I test my function, it gives me NO runtime error!
but the anonymous functions from the MakeRequest call and the request.get call wont execute, and I don't know why.
For Example the console output:
Hallo!,
Asd (very funny.. it gets the params for the request.get.. the bug has to be between the second param(the anon function itself?) in the call and the start of the anon function),
hffggh,
asdww
-the console.logs in the anon. functions doesn't show.
I maybe undestand why the MakeRequest funct. doesn't run -> because the callback from it never came. But why does the request.get not work?? I pasted the necessary parts (the MakeRequest and the helper functions) in a normal node projekt, and it worked!!? -facepalm.... im nearly crying..
My Goal: I want to receive a response from the server.. - thats all. But it just wont go into the function where I can access the response object(s).
(Scroll down to the helper functions)
Please help me out guys, I could really hit my head against the wall.

I need to use $q to wait until my async function has completed and then do something.
However I have tried injecting $q into my angular module as well as my angular functions and I am getting the message $q is undefined.
Can someone tell me how I can go about being able to use this in my code?
Here is the code for the module and the function I want to use $q in respectively
Module
var droidSync = angular.module('droidSync', ['ionic', 'ngRoute', 'ui.router']);
Controller and FunctionIn this case I want to wait for the results.forEach to finish then I want to hide my loading screen using $ionicLoading.hide()
droidSync.controller('mainController', function ($scope, $ionicLoading) {
$scope.syncContacts = function () {
//Display a loading screen while sync is in execution
$ionicLoading.show({
template: '<p>Syncing Contacts...</p><ion-spinner class="spinner-calm" icon="crescent"/>'
});
var table = AzureService.getTable('contact');
table.read().done(function (results) {
results.forEach(function (result) { //THIS NEEDS TO BE COMPLETE BEFORE HIDING LOAD SCREEN
console.log('result is', result);
// If the contact is flagged as deleted check if its on the device and delete it
if (result.isdeleted == true) {
var options = new ContactFindOptions();
options.filter = result.id;
options.multiple = false;
var fields = ["*"];
navigator.contacts.find(fields, findSuccess, findError, options);
function findSuccess(contact) {
if (contact.length > 0) {

contactToDelete.id = contact[0].id;

console.log('we want to delete this', contactToDelete);
contactToDelete.remove();
console.log('Contact Deleted');
}
else {
console.log('Contact to delete not present on device. Checking next contact');
}
}
function findError() {
console.log('Contact search failed: Deleted Contact Search');
}
}
else {
//create a contact object to save or update
var emails = [];
var phoneNumbers = [];
var name = new ContactName();

var options = new ContactFindOptions();
options.filter = result.id;

var fields = ["*"];
navigator.contacts.find(fields, foundSuccess, foundError, options);
function foundSuccess(contact) {
if (contact.length > 0) {
//The contact has been found on the device. Pass in ids for contact, emails and phone numbers to update.
console.log('object to update is object is', contact);
console.log('contact array length is ', contact.length);
contactToUpdate.id = contact[0].id;
contactToUpdate.rawId = contact[0].rawId;
contactToUpdate.phoneNumbers[0].id = contact[0].phoneNumbers[0].id;
contactToUpdate.phoneNumbers[1].id = contact[0].phoneNumbers[1].id;
contactToUpdate.emails[0].id = contact[0].emails[0].id;
console.log('about to save this', contactToUpdate);
contactToUpdate.save(upSuccess, upError);
function upSuccess() {
console.log('updated a contact!');
}
function upError(ContactError) {
console.log('error updating a contact!');
}
}
else {
//The contact does not exist on the device. Just save it.
console.log('non existent contact: ', contactToUpdate);
contactToUpdate.save(saveSuccess, SaveError);
function saveSuccess() {
console.log('saved a contact!');
}
function SaveError() {
console.log('error saving a contact!');

}
function foundError() {
console.log('Contact search failed: Undeleted Contact Search');
}
} // end else
})) // end forEach
}) // table.read()
}; // scope.syncContacts()
});
So i'd probably do something like this
This is completely untested code so take that for what you will
$q.all is what your going to want to look into
droidSync.controller('mainController', ["$scope", "$q", "$ionicLoading",
function ($scope, $q, $ionicLoading) {
var loop = function(result){
var deferred = $q.defer();
deferred.resolve(// your loop stuff);
return deferred.promise;
};
var loopingFunction = function(results){
var promises = [];
results.forEach(function(result){
promises.push(loop(result));
});
return $q.all(promises);
};
$scope.syncContacts = function () {
//Display a loading screen while sync is in execution
$ionicLoading.show({
template: '<p>Syncing Contacts...</p><ion-spinner class="spinner-calm" icon="crescent"/>'
});
var table = AzureService.getTable('contact');
table.read().done(function (results) {
loopingFunction(results).then(function(){
// do something after it finishes
$ionicLoading.hide()
});
});
};
}]);

The answer is to make sure to effect the model. For example: uwrl.alpha[0].customerName instead of urwl.beta
I'm building an offline HTML page using Angular and using ydn-db for offline storage.
I have a database service like so,
demoApp.SericeFactory.database = function database() {
var database = {
dataStore: null,
admins: [],
students: [],
errors: [],
getadmindata: function(username) {
self = null, that = this
database.dataStore.get('admins', username).done(function(record) {
that.self = record;
return record;
}).fail(function(e) {
console.log(e);
database.errors.push(e);
});
return self; //This does not change.
}
};
database.dataStore = new ydn.db.Storage('DemoApp');
angular.forEach(INITSTUDENTS, function(student) {
database.dataStore.put('students', student, student.matricno);
database.students.push(student);
});
angular.forEach(INITADMINS, function(admin) {
database.dataStore.put('admins', admin, admin.username);
database.admins.push(admin);
});
return database;
I also have a controller that attempts to use the database;
function AppCntl ($scope, database) {
var user = database.getadmindata('user'); //I get nothing here.
}
What I have tried,
I have tried making changing self to var self
I have tried splitting the function like so
rq = database.dataStore.get('admins', 'user');
rq.done(function(record), {
self = record;
alert(self.name) //Works.
});
alert(self) //Doesn't work.
I have gone through questions like this o StackOverflow but nothings seems to be working for me or maybe I have just been looking in the wrong place.
Database request are asynchronous and hence it executes later after end of execution of the codes.
So when the last alert execute, self is still undefined. Secound alert execute after db request completion and it is usual right design pattern.
EDIT:
I have success with following code:
// Database service
angular.module('myApp.services', [])
.factory('database', function() {
return new ydn.db.Storage('feature-matrix', schema);
}
});
// controller using database service
angular.module('myApp.controllers', [])
.controller('HomeCtrl', ['$scope', 'utils', 'database', function($scope, utils, db) {
var index_name = 'platform, browser';
var key_range = null;
var limit = 200;
var offset = 0;
var reverse = false;
var unique = true;
db.keys('ydn-db-meta', index_name, key_range, limit, offset, reverse, unique)
.then(function(keys) {
var req = db.values('ydn-db', keys);
req.then(function(json) {
$scope.results = utils.processResult(json);
$scope.$apply();
}, function(e) {
throw e;
}, this);
});
}])
