I have seen lots of questions about this but all of the fixes simply does not work with my code.
What am I doing wrong? My beforeEach doesnt get executed.
This is the unit test code:
var assert = require('assert');
var environmentConfiguration;
var fs = require('fs');
var expect = require('chai').expect;
describe('environmentConfiguration', function() {
beforeEach('some description', function() {
console.log("hello")
});
describe('#configFile null configFile', function() {
var result = environmentConfiguration.load(null)
var expectedConfiguration = JSON.parse(fs.readFileSync('./ISPRemotingService.config.json'));
it('should return current ISP environment configuration', function() {
assert(result, expectedConfiguration);
});
});
});
I have also applied simpler versions from Mocha's documentation and beforeEach doesn't gets executed.
Another exception was blocking the unit tests to even reach there. My bad

My Protractor test fails with below error
Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL.
This is my spec file.
let common=require('./Objects/common.js')
describe('Cloud testing', function() {
it('Cloudtest1', function() {
let EC=protractor.ExpectedConditions;
browser.waitForAngularEnabled(false);
browser.get(common.loginURL);
common.txtUserName.sendKeys('aqaasdas#hkm.com');
common.txtPword.sendKeys('asdasd##$');
common.btnLogin.click();
browser.wait(EC.visibilityOf(element(by.xpath("//a[#class='btn btn-success']"))));
element(by.xpath("//a[#class='btn btn-success']")).click();
common.btnCrtPcr.click();
});
});
Any help is appreciated, I tried answers to similar questions posted here but nothing works for me. I'm running the latest Protractor and Chrome versions.
Have you tried by asyn test? Sometimes even backend response or browser performance may affect the test cases.
Refer: https://jasmine.github.io/2.0/introduction.html#section-Asynchronous_Support
describe("Your module", function() {
var originalTimeout;
beforeEach(function() {
originalTimeout = jasmine.DEFAULT_TIMEOUT_INTERVAL;
jasmine.DEFAULT_TIMEOUT_INTERVAL = 10000;
});
it("takes a long time", function(done) {
let EC=protractor.ExpectedConditions;
browser.waitForAngularEnabled(false);
browser.get(common.loginURL);
common.txtUserName.sendKeys('aqaasdas#hkm.com');
common.txtPword.sendKeys('asdasd##$');
common.btnLogin.click();
browser.wait(EC.visibilityOf(element(by.xpath("//a[#class='btn btn-success']"))));
element(by.xpath("//a[#class='btn btn-success']")).click();
common.btnCrtPcr.click();
});
afterEach(function() {
jasmine.DEFAULT_TIMEOUT_INTERVAL = originalTimeout;
});
});
Your callback was later than your Jasmins default timout time. You might want to use async/await in your it block even though you have used expected condition.
it('Cloudtest1', async () => {
let EC=protractor.ExpectedConditions;
browser.waitForAngularEnabled(false);
browser.get(common.loginURL);
await common.txtUserName.sendKeys('aqaasdas#hkm.com');
await common.txtPword.sendKeys('asdasd##$');
await common.btnLogin.click();
browser.wait(EC.visibilityOf(element(by.xpath("//a[#class='btn btn-success']"))));
element(by.xpath("//a[#class='btn btn-success']")).click();
await common.btnCrtPcr.click();
});
Suggestion: Perform action in page object or before each/all. Use it block for expect statement.
example:
describe('When user logged Into account ', () => {
beforeAll(async () => {
await browser.waitForAngularEnabled(false);
await loginPO.login();
});
it('Browser title should be displayed.', async () => {
expect(await browser.getTitle()).toBe('test');
});
});
I just started learning Jasmine test cases for angularjs. I am unable to test below code.Kindly help
$scope.getConstants = function(lovName) {
ConstantService.getConstants(lovName).then(function(d) {
switch (lovName) {
case 'WORKFLOW':
$scope.workflowTypes = d;
$scope.loadCounterpartyTmp();
break;
--------Other Cases
}
My ConstantService is defined as
App.factory('ConstantService', [ '$http', '$q', function($http, $q) {
return {
getConstants : function(lovName) {
return $http.post('/sdwt/data/getConstants/', lovName).then(function(response) {
return response.data;
}, function(errResponse) {
return $q.reject(errResponse);
});
}
I want to test getConstants function.I need to create a mock of ConstantService and pass the data to it.
I have written below test case but the test case is not working.Please let me know how to test the above code
describe('getConstantsForMurexEntity', function() {
it('testing getConstantsForMurexEntity function', function() {
var d=[];
d.push(
{id:1,value:'ABC'},
{id:2,value:'DEF'},
{id:3,value:'IJK'},
{id:4,value:'XYZ'},
);
//defined controller
spyOn(ConstantService, 'getConstants').and.returnValue(d);
$scope.getConstants('WORKFLOW');
expect($scope.workflowTypes).toBe(d);
The above test case is not working as it is saying "ConstantService.getConstants(...).then is not a function".
Your ConstantService.getConstants() function returns a promise, which your actual code is using, with the .then() call. This means means that when you spy on it, you also need to return a promise, which you are not doing. Because you are not returning a promise, when your actual call tries to call .then(), it is undefined, which is the reason for the error message.
Also, you aren't using Array.push correctly.
Your test should probably look something like the following (note, this is untested):
describe('getConstantsForMurexEntity', function() {
it('should set workflowTypes to the resolved value when lovName is "WORKFLOW"', inject(function($q) {
var deferred = $q.defer();
spyOn(ConstantService, 'getConstants').and.returnValue(deferred.promise);
var d = [
{id:1,value:'ABC'},
{id:2,value:'DEF'},
{id:3,value:'IJK'},
{id:4,value:'XYZ'},
];
$scope.getConstants('WORKFLOW');
deferred.resolve(d);
$scope.$apply();
expect($scope.workflowTypes).toBe(d);
}));
});
I have a suite which includes multiple specs. Each spec uses code on some libraries that return a rejected promise upon failure.
I can easily catch those rejected promises inside my spec. What I'm wondering about is that if I can make Protractor exit the whole suite inside that catch function, because the next specs inside the same suite are dependent on the success of the previous specs.
Pretend I have a suite called testEverything which has these specs openApp,signIn,checkUser,logout. If openApp fails, all next specs will fail due to dependency.
Consider this code for openApp:
var myLib = require('./myLib.js');
describe('App', function() {
it('should get opened', function(done) {
myLib.openApp()
.then(function() {
console.log('Successfully opened app');
})
.catch(function(error) {
console.log('Failed opening app');
if ( error.critical ) {
// Prevent next specs from running or simply quit test
}
})
.finally(function() {
done();
});
});
});
How would I exit the whole test?
There is a module for npm called protractor-fail-fast. Install the module npm install protractor-fail-fast. Here's an example from their site where you would place this code into your conf file:
var failFast = require('protractor-fail-fast');
exports.config = {
plugins: [{
package: 'protractor-fail-fast'
}],
onPrepare: function() {
jasmine.getEnv().addReporter(failFast.init());
},
afterLaunch: function() {
failFast.clean(); // Cleans up the "fail file" (see below)
}
}
Their url is here.
I have managed to come up with a workaround. Now the actual code that I used is way more complex, but the idea is the same.
I added a global variable inside protractor's config file called bail. Consider the following code at the top of config file:
(function () {
global.bail = false;
})();
exports.config: { ...
The above code uses an IIFE (Immediately Invoked Function Expression) which defines bail variable on protractor's global object (which would be available throughout the whole test).
I also have written asynchronous wrappers for the Jasmine matchers I need, which would execute an expect expression followed by a comparison, and return a promise (using Q module). Example:
var q = require('q');
function check(actual) {
return {
sameAs: function(expected) {
var deferred = q.defer();
var expectation = {};
expect(actual).toBe(expected);
expectation.result = (actual === expected);
if ( expectation.result ) {
deferred.resolve(expectation);
}
else {
deferred.reject(expectation);
}
return deferred.promise;
}
};
}
module.exports = check;
Then at the end of each spec, I set the bail value based on the spec's progress, which would be determined by the promise of those asynchronous matchers. Consider the following as first spec:
var check = require('myAsyncWrappers'); // Whatever the path is
describe('Test', function() {
it('should bail on next spec if expectation fails', function(done) {
var myValue = 123;
check(myValue).sameAs('123')
.then(function(expectation) {
console.log('Expectation was met'); // Won't happen
})
.catch(function(expectation) {
console.log('Expectation was not met'); // Will happen
bail = true; // The global variable
})
.finally(function() {
done();
});
});
});
Finally, on the beginning of next specs, I check for bail and return if necessary:
describe('Test', function() {
it('should be skipped due to bail being true', function(done) {
if ( bail ) {
console.log('Skipping spec due to previous failure');
done();
return;
}
// The rest of spec
});
});
Now I want to mention that there's one module out there called protractor-fail-fast which bails on the whole test whenever an expectation fails.
But in my case, I needed to set that bail global variable depending on which type of expectation has been failed. I ended up writing a library (really small) that distinguishes failures as critical and non-critical and then using that, specs would be stopped only if a critical failure has occurred.
Here are 2 samples of the same test. The only difference is that first one uses a promise in beforeAll block to assign a value to the variable while the second one assigns the value directly.
I raised a similar question Running spec after promise has been resolved with one of the comments pointing to this issue https://github.com/jasmine/jasmine/issues/412 which says that this is not supported in Jasmine. Has somebody figured out any workaround?
This fails with TypeError: Cannot read property 'forEach' of undefined
describe('Async car test', function () {
var cars;
beforeAll(function (done) {
// getCars() is a promise which resolves to ['audi', 'bmw']
getCars().then(function (data) {
cars = data;
console.log(cars) // ['audi', 'bmw']
done();
});
});
cars.forEach(function (car) {
it('car ' + car, function () {
expect(car).toBe(car);
});
});
});
This works fine
describe('Car test', function () {
var cars = ['audi', 'bmw'];
cars.forEach(function (car) {
it('car ' + car, function () {
expect(car).toBe(car);
});
});
});
Posting it as an answer, because I can't see things properly in comments.
I'm actually generating tests in my spec as well, and I'm using https://www.npmjs.com/package/jasmine-data-provider , I think you probably cannot generate it directly from resolved promise. And wrapping in another it doesn't work for you. This should work:
var using = require('jasmine-data-provider');
using(cars.forEach, function (car) {
it(car + ' should be' + car, function () {
expect(car).toBe(car);
});
});
This is not an issue with jasmine, it is an issue with your code.
beforeAll does not block subsequent code below the statement. it blocks code that is defined in it('should ...', (done)=>{...});
it('should have cars', (done) => {
cars.forEach(function (car) {
expect(car).toBe(car);
});
});
Since Jasmine does not support adding tests at runtime, the trick is to request the asynchronous data before starting Jasmine, and then using the retrieved data during runtime instead. This can be achieved with a singleton and programmatically starting Jasmine.
See here for a working example.
// car-collection.js
class CarCollection {
static load() {
return this.request()
then((data) => this.cars = data);
}
static request() {
// in practice this function would do something cooler
return Promise.resolve(['audi', 'bmw']);
}
}
modules.export = CarCollection;
Since CarCollection has methods that are static they will be shared across imports and this.cars will persist.
// launcher.js
const Jasmine = require('jasmine');
const CarCollection = require('./car-collection');
CarCollection.load()
.then(() => {
console.log(`car count is ${CarCollection.cars.length}`); // prints: car count is 2
const jasmine = new Jasmine();
jasmine.loadConfigFile(...); // path to jasmine.json
jasmine.execute();
});
An important step here is configure jasmine to know where to look for the test files. Either by loading a config or passing specifics into the execute function.
// car.spec.js
const CarCollection = require('./car-collection');
describe('test', function () {
CarCollection.cars.forEach((car) => {
it('test' + car, () => {
expect(car).toBe(car);
});
});
});
Now run node ./launcher.js and the tests should run.
describe('my homepage', function() {
var ptor = protractor.getInstance();
beforeEach(function(){
// ptor.ignoreSynchronization = true;
ptor.get('http://localhost/myApp/home.html');
// ptor.sleep(5000);
})
describe('login', function(){
var email = element.all(protractor.By.id('email'))
, pass = ptor.findElement(protractor.By.id('password'))
, loginBtn = ptor.findElement(protractor.By.css('#login button'))
;
it('should input and login', function(){
// email.then(function(obj){
// console.log('email', obj)
// })
email.sendKeys('josephine#hotmail.com');
pass.sendKeys('shakalakabam');
loginBtn.click();
})
})
});
the above code returns
Error: Error while waiting for Protractor to sync with the page: {}
and I have no idea why this is, ptor load the page correctly, it seem to be the selection of the elements that fails.
TO SSHMSH:
Thanks, your almost right, and gave me the right philosophy, so the key is to ptor.sleep(3000) to have each page wait til ptor is in sync with the project.
I got the same error message (Angular 1.2.13). My tests were kicked off too early and Protractor didn't seem to wait for Angular to load.
It appeared that I had misconfigured the protractor config file. When the ng-app directive is not defined on the BODY-element, but on a descendant, you have to adjust the rootElement property in your protractor config file to the selector that defines your angular root element, for example:
// protractor-conf.js
rootElement: '.my-app',
when your HTML is:
<div ng-app="myApp" class="my-app">
I'm using ChromeDriver and the above error usually occurs for the first test. I've managed to get around it like this:
ptor.ignoreSynchronization = true;
ptor.get(targetUrl);
ptor.wait(
function() {
return ptor.driver.getCurrentUrl().then(
function(url) {
return targetUrl == url;
});
}, 2000, 'It\'s taking too long to load ' + targetUrl + '!'
);
Essentially you are waiting for the current URL of the browser to become what you've asked for and allow 2s for this to happen.
You probably want to switch the ignoreSynchronization = false afterwards, possibly wrapping it in a ptor.wait(...). Just wondering, would uncommenting the ptor.sleep(5000); not help?
EDIT:
After some experience with Promise/Deferred I've realised the correct way of doing this would be:
loginBtn.click().then(function () {
ptor.getCurrentUrl(targetUrl).then(function (newURL){
expect(newURL).toBe(whatItShouldBe);
});
});
Please note that if you are changing the URL (that is, moving away from the current AngularJS activated page to another, implying the AngularJS library needs to reload and init) than, at least in my experience, there's no way of avoiding the ptor.sleep(...) call. The above will only work if you are staying on the same Angular page, but changing the part of URL after the hashtag.
In my case, I encountered the error with the following code:
describe("application", function() {
it("should set the title", function() {
browser.getTitle().then(function(title) {
expect(title).toEqual("Welcome");
});
});
});
Fixed it by doing this:
describe("application", function() {
it("should set the title", function() {
browser.get("#/home").then(function() {
return browser.getTitle();
}).then(function(title) {
expect(title).toEqual("Welcome");
});
});
});
In other words, I was forgetting to navigate to the page I wanted to test, so Protractor was having trouble finding Angular. D'oh!
The rootElement param of the exports.config object defined in your protractor configuration file must match the element containing your ng-app directive. This doesn't have to be uniquely identifying the element -- 'div' suffices if the directive is in a div, as in my case.
From referenceConf.js:
// Selector for the element housing the angular app - this defaults to
// body, but is necessary if ng-app is on a descendant of <body>
rootElement: 'div',
I got started with Protractor by watching the otherwise excellent egghead.io lecture, where he uses a condensed exports.config. Since rootElement defaults to body, there is no hint as to what is wrong with your configuration if you don't start with a copy of the provided reference configuration, and even then the
Error while waiting for Protractor to sync with the page: {}
message doesn't give much of a clue.
I had to switch from doing this:
describe('navigation', function(){
browser.get('');
var navbar = element(by.css('#nav'));
it('should have a link to home in the navbar', function(){
//validate
});
it('should have a link to search in the navbar', function(){
//validate
});
});
to doing this:
describe('navigation', function(){
beforeEach(function(){
browser.get('');
});
var navbar = element(by.css('#nav'));
it('should have a link to home in the navbar', function(){
//validate
});
it('should have a link to search in the navbar', function(){
//validate
});
});
the key diff being:
beforeEach(function(){
browser.get('');
});
hope this may help someone.
I was getting this error:
Failed: Error while waiting for Protractor to sync with the page: "window.angular is undefined. This could be either because this is a non-angular page or because your test involves client-side navigation, which can interfere with Protractor's bootstrapping. See http://git.io/v4gXM for details"
The solution was to call page.navigateTo() before page.getTitle().
Before:
import { AppPage } from './app.po';
describe('App', () => {
let page: AppPage;
beforeEach(() => {
page = new AppPage();
});
it('should have the correct title', () => {
expect(page.getTitle()).toEqual('...');
})
});
After:
import { AppPage } from './app.po';
describe('App', () => {
let page: AppPage;
beforeEach(() => {
page = new AppPage();
page.navigateTo();
});
it('should have the correct title', () => {
expect(page.getTitle()).toEqual('...');
})
});
If you are using
browser.restart()
in your spec some times, it throws the same error.
Try to use
await browser.restart()
