I currently run my angularjs testing environment using ngMockEE which, using a special testing module allows me to mock http responses as such;
var things = [thing01, thing02];
$httpBackend.whenGET('/v1/things?').respond(function() {return [200, things]});
In a separate file I define e2e tests which call a things.html file that includes that testing module.
I then define a e2e test like this;
browser().navigateTo('/test/thingTest.html');
expect(element('.table.things tbody tr').count()).toEqual(2);
Now, what would be nice is if I could somehow couple the two togther, so that I could write an assertion like this - avoiding hard coding that 2 which will need updating over time if I update my list of things
browser().navigateTo('/test/thingTest.html');
expect(element('.table.things tbody tr').count()).toEqual(things.length);
However I'm not quite sure if this is possible or advisable. Any thoughts?
Well, you could use an e2eData.js file containing those values, and which would be loaded both by your tests, and by the tested page:
In e2eData.js:
...
var e2eData = {
things : [thing01, thing02],
...
}
In your e2e module:
$httpBackend.whenGET('/v1/things?').respond(function() {return [200, e2eData.things]});
In your test:
expect(element('.table.things tbody tr').count()).toEqual(e2eData.things.length);

Is there way to merge 2 commands into 1 command
protractor protractor.conf --suite create_buyer --params.buyerName=Buyer1
protractor protractor.conf --suite create_buyer --params.buyerName=Buyer2
like
protractor protractor.conf --suite create_buyer,create_buyer --params.suites[0].buyerName=Buyer1 --params.suites[1].buyerName=Buyer2
to make this commad work i need to know the current suite index
is it possible?
may there is better way!
As far as i know, there is no way you can do it using Protractor. However, if you want to run the same suite twice, then there is a better way of handling this situation using data-providers. There are many ways to create a data driven framework for protractor, but the easiest one that i feel is using jasmine-data-provider, which is an npm package. Here's how you can do it -
Update conf.js file to include the suite and params -
suites: {
create_buyer: ['./firstSpec.js'] //All your specs
},
params: {
buyerName1: '',
buyerName2: ''
},
Update all test scripts file to include the dataprovider -
//Require the dataprovider
var dp = require('/PATH_TO/node_modules/jasmine-data-provider'); //Update your path where the jasmine-data-provider is installed
//Usage of dataprovider in your specs
var objectDataProvider = {
'Test1': {buyerName: browser.params.buyerName1},
'Test2': {buyerName: browser.params.buyerName2}
};
dp(objectDataProvider, function (data, description) {
//Whole describe or anything in the dp() runs twice
describe('First Suite Test: ', function(){
it('First Spec', function(){
element.sendKeys(data.buyerName); //usage of the data buyerNames
//Your code for the spec
});
//All your specs
});
});
Now pass in the parameters using command prompt -
protractor protractor.conf --suite create_buyer --params.buyerName1=Buyer1 --params.buyerName2=Buyer2
NOTE: However the issue here is that you cannot run one single suite at a single stretch with one buyerName. For ex: You cannot run all specs in the suite create_buyer at one stretch using buyerName1. Instead, one spec will run twice serially, once with buyerName1 and buyerName2, then it continues to next spec. But i guess, that should also work if your requirement is to not use a strict flow for one buyer (i.e, to complete end-to-end testing of suite create_buyer with buyerName1 and then run suite create_buyer with buyerName2 - this shouldn't be the case as the thumb rule of automation says that one test script shouldn't depend on another).
Hope it helps
I'm new to Angular and Karma and every site out there seems to recommend a different way of writing unit tests, which makes all of this very confusing. Help is appreciated!
I have a helper class that has a dependency on a service class. I am writing a unit test for the helper class. I have this:
module("myModule");
it('works!', inject(function(myHelper) {
module(function($provide) {
$provide.service('myService', function() {
payload = spyOn(myService, 'getPayload').andReturn(
{id: 1 });
});
});
expect(myHelper.getSomeData()).toEqual(exepectedData);
}));
The exception I'm getting when running the test is:
Error: [$injector:unpr] Unknown provider: myHelperProvider <- myHelper
I've tried all different ways of doing this, but haven't gotten it to work yet.
Try calling module("myModule"); in a beforeEach, i.e.:
beforeEach(module('myModule'));
You may have luck with actually calling the function returned by module("myModule"), i.e.:
module("myModule")();
... but have never tried this and I have serious doubts.
Also I always enclose my it() specs in a describe() block; not sure if strictly necessary though.
I'm part of a team that's been working on angularjs for quite a while now and our unit tests consist of files which contain both the test logic and provider mocks of each component that tested element relies on.
This is leading to more and more code duplication, can anyone recommend an angular-ey method whereby we could maintain a test infrastructure, mock a controller or service once and be able to inject that mocked service into other tests as required?
Edit The code I'm working with is proprietary but for an example consider you have 10 or 15 services which retrieve data via HTTP requests, format the data in different ways and return that data. One example might return arrays of data so in each file which relies on the service we would have initialising code like the following ( cut down and altered so please ignore any typos or other mistakes )
myDataService: {
getDataParsedLikeY: {
[{obj1},{obj2}...]
},
getDataParsedLikeX: {
[{obja},{objb}...]
}
beforeEach(angular.mock.module('myModule'));
beforeEach(angular.mock.inject(function(myDataService) {
myDataService = function( functionName ) {
return myDataService[functionName];
}
spyOn(myDataService).and.callThrough();
})
}
If you are looking for a way not to declare same mock codes in every test files, I would suggest something like below although I'm not sure this is angular-way or not.
[1] write the code to declare your mock services like below only for unit test and import after angular-mocks.js
In your-common-mocks.js(you can name the file as you like)
(function(window){
window.mymock = {};
window.mymock.prepare_mocks = function(){
module(function($provide) {
$provide.service('myDataService', function(){
this.getDataParsedLikeY = function(){
return 'your mock value';
};
});
});
};
})(window);
If you use karma, you could write like this to import the file in karma.conf.js.
files: [
...
'(somedirctory)/angular-mocks.js',
'(somedirctory)/your-common-mocks.js'
...
]
[2] use mymock.prepare_mocks function in your test files.
describe('Some Test', function() {
beforeEach(mymock.prepare_mocks);
it('getDataParsedLikeY', inject(function(myDataService){
expect('your mock value', myDataService.getDataParsedLikeY());
As a result of above, you have to write your mock code just one time and share the mock code in your every test files. I hope this could suggest you something to achieve what you want.
If your jasmine version is 2.x, you can write test code like below without writing mock service.
spyOn(YourService, 'somemethod').and.returnValue('mock value');
In jasmine 1.3 you need to adjust little bit.
spyOn(YourService, 'somemethod').andReturn('mock value');
I hope this could help you.
I have created tests for my application. Everything works but it runs slow and even though only 1/3 of the application is tested it still takes around ten minutes for protrator to create the test data, fill out the fields, click the submit button etc.
I am using Google Crome for the testing. It seems slow as I watch protractor fill out the fields one by one.
Here's an example of my test suite:
suites: {
login: ['Login/test.js'],
homePage: ['Home/test.js'],
adminPage: ['Admin/Home/test.js'],
adminObjective: ['Admin/Objective/test.js'],
adminObjDetail: ['Admin/ObjectiveDetail/test.js'],
adminTopic: ['Admin/Topic/test.js'],
adminTest: ['Admin/Test/test.js'],
adminUser: ['Admin/User/test.js'],
adminRole: ['Admin/Role/test.js']
},
This is one test group:
login: ['Login/test.js'],
homePage: ['Home/test.js'],
adminUser: ['Admin/User/test.js'],
adminRole: ['Admin/Role/test.js']
This is another test group:
adminPage: ['Admin/Home/test.js'],
adminObjective: ['Admin/Objective/test.js'],
adminObjDetail: ['Admin/ObjectiveDetail/test.js'],
adminTopic: ['Admin/Topic/test.js'],
adminTest: ['Admin/Test/test.js'],
The two groups can run independently but they must run in the order I have above. After the answers I did read about sharing but I am not sure if this helps my situation as my tests need to be run in order. Ideally I would like to have one set of tests run in one browser and the other set in another browser.
I read about headless browsers such as PhantomJS. Does anyone have experience with these being faster?
Any advice on how I could do this would be much appreciated.
We currently use "shardTestFiles: true" which runs our tests in parallel, this could help if you have multiple tests.
I'm not sure what you are testing here, whether its the data creation or the end result. If the latter, you may want to consider mocking the data creation instead or bypassing the UI some other way.
Injecting in Data
One thing that you can do that will give you a major boost in performance is to not double test. What I mean by this is that you end up filling in dummy data a number of times to get to a step. Its also one of the major reasons that people need tests to run in a certain order (to speed up data entry).
An example of this is if you want to test filtering on a grid (data-table). Filling in data is not part of this action. Its just an annoying thing that you have to do to get to testing the filtering. By calling a service to add the data you can bypass the UI and seleniums general slowness (Id also recommend this on the server side by injecting values directly into the DB using migrations).
A nice way to do this is to add a helper to your pageobject as follows:
module.exports = {
projects: {
create: function(data) {
return browser.executeAsyncScript(function(data, callback) {
var api = angular.injector(['ProtractorProjectsApp']).get('apiService');
api.project.save(data, function(newItem) {
callback(newItem._id);
})
}, data);
}
}
};
The code in this isnt the cleanest but you get the general gist of it. Another alternative is to replace the module with a double or mock using [Protractor#addMockModule][1]. You need to add this code before you call Protractor#get(). It will load after your application services overriding if it has the same name as an existing service.
You can use it as follows :
var dataUtilMockModule = function () {
// Create a new module which depends on your data creation utilities
var utilModule = angular.module('dataUtil', ['platform']);
// Create a new service in the module that creates a new entity
utilModule.service('EntityCreation', ['EntityDataService', '$q', function (EntityDataService, $q) {
/**
* Returns a promise which is resolved/rejected according to entity creation success
* #returns {*}
*/
this.createEntity = function (details,type) {
// This is your business logic for creating entities
var entity = EntityDataService.Entity(details).ofType(type);
var promise = entity.save();
return promise;
};
}]);
};
browser.addMockModule('dataUtil', dataUtilMockModule);
Either of these methods should give you a significant speedup in your testing.
Sharding Tests
Sharding the tests means splitting up the suites and running them in parallel. To do this is quite simple in protractor. Adding the shardTestFiles and maxInstences to your capabilities config should allow you to (in this case) run at most two test in parrallel. Increase the maxInstences to increase the number of tests run. Note : be careful not to set the number too high. Browsers may require multiple threads and there is also an initialisation cost in opening new windows.
capabilities: {
browserName: 'chrome',
shardTestFiles: true,
maxInstances: 2
},
Setting up PhantomJS (from protractor docs)
Note: We recommend against using PhantomJS for tests with Protractor. There are many reported issues with PhantomJS crashing and behaving differently from real browsers.
In order to test locally with PhantomJS, you'll need to either have it installed globally, or relative to your project. For global install see the PhantomJS download page (http://phantomjs.org/download.html). For local install run: npm install phantomjs.
Add phantomjs to the driver capabilities, and include a path to the binary if using local installation:
capabilities: {
'browserName': 'phantomjs',
/*
* Can be used to specify the phantomjs binary path.
* This can generally be ommitted if you installed phantomjs globally.
*/
'phantomjs.binary.path': require('phantomjs').path,
/*
* Command line args to pass to ghostdriver, phantomjs's browser driver.
* See https://github.com/detro/ghostdriver#faq
*/
'phantomjs.ghostdriver.cli.args': ['--loglevel=DEBUG']
}
Another speed tip I've found is that for every test I was logging in and logging out after the test is done. Now I check if I'm already logged in with the following in my helper method;
# Login to the system and make sure we are logged in.
login: ->
browser.get("/login")
element(By.id("username")).isPresent().then((logged_in) ->
if logged_in == false
element(By.id("staff_username")).sendKeys("admin")
element(By.id("staff_password")).sendKeys("password")
element(By.id("login")).click()
)
I'm using grunt-protractor-runner v0.2.4 which uses protractor ">=0.14.0-0 <1.0.0".
This version is 2 or 3 times faster than the latest one (grunt-protractor-runner#1.1.4 depending on protractor#^1.0.0)
So I suggest you to give a try and test a previous version of protractor
Hope this helps
Along with the great tips found above I would recommend disabling Angular/CSS Animations to help speed everything up when they run in non-headless browsers. I personally use the following code in my Test Suite in the "onPrepare" function in my 'conf.js' file:
onPrepare: function() {
var disableNgAnimate = function() {
angular
.module('disableNgAnimate', [])
.run(['$animate', function($animate) {
$animate.enabled(false);
}]);
};
var disableCssAnimate = function() {
angular
.module('disableCssAnimate', [])
.run(function() {
var style = document.createElement('style');
style.type = 'text/css';
style.innerHTML = '* {' +
'-webkit-transition: none !important;' +
'-moz-transition: none !important' +
'-o-transition: none !important' +
'-ms-transition: none !important' +
'transition: none !important' +
'}';
document.getElementsByTagName('head')[0].appendChild(style);
});
};
browser.addMockModule('disableNgAnimate', disableNgAnimate);
browser.addMockModule('disableCssAnimate', disableCssAnimate);
}
Please note: I did not write the above code, I found it online while looking for ways to speed up my own tests.
From what I know:
run test in parallel
inject data in case you are only testing a UI element
use CSS selectors, no xpath (browsers have a native engine for CSS, and the xpath engine is not performance as CSS engine)
run them on high performant machines
use as much as possible beforeAll() and beforeEach() methods for instructions that you repeat often in multiple test
Using Phantomjs will considerably reduce the duration it takes in GUI based browser, but better solution I found is to manage tests in such a way that it can be run in any order independently of other tests, It can be achieved easily by use of ORM(jugglingdb, sequelize and many more) and TDB frameworks, and to make them more manageable one can use jasmine or cucumber framework, which has before and after hookups for individual tests. So now we can gear up with maximum instances our machine can bear with "shardTestFiles: true".
A hot discussion raised between me and my boss about Angular E2E testing. according to vojitajina pull request we need to run a server in order to run the e2e tests. So, running e2e test involves a real server, a real server involves DB. This makes test slow.Ok, now the question is how to test e2e without involving a real server ? is there a way to use httpBackend to and the e2e angular API where I can use browser(), element(), select(), for my tests ?
[see edit below] We use a shell script to periodically capture curl requests from our seeded test server. These responses are then returned via $httpBackend.whenGet(...).respond() to intercept and return that data.
So, in our index.html
if (document.location.hash === '#test') {
addScript('/test/lib/angular-mocks.js');
addScript('/test/e2e/ourTest.js');
window.fixtures = {};
addScript('/test/fixtures/tasks/tasks_p1.js');
// the tasks_p1.js is generated and has "window.fixtures.tasks_p1 = ...json..."
addScript('/test/fixtures/tasks/tasks_p2.js');
// the tasks_p2.js is generated and has "window.fixtures.tasks_p2 = ...json..."
addScript('/test/e2e/tasks/taskMocks.js\'><\/script>');
}
ourTest.js
angular.module('ourTestApp', ['ngMockE2E','taskMocks']).
run(function ($httpBackend, taskMocks) {
$httpBackend.whenGET(/views\/.*/).passThrough();
$httpBackend.whenGET(/\/fixtures.*\//).passThrough();
taskMocks.register();
$httpBackend.whenGET(/.*/).passThrough();
});
taskMocks.js
/*global angular */
angular.module('taskMocks', ['ngMockE2E']).
factory('taskMocks', ['$httpBackend', function($httpBackend) {
'use strict';
return {
register: function() {
$httpBackend.whenGET(..regex_for_url_for_page1..).respond(window.fixtures.tasks_p1);
$httpBackend.whenGET(..regex_for_url_for_page2..).respond(window.fixtures.tasks_p2);
}
};
}]);
In a few cases our data is related to the current date; e.g. "tasks for this week", so we massage the captured data in the register() method.
EDIT
We now use Rosie to create factories for our mocked objects. So, no more CURLing test server for expected json responses. index.html no longer loads these ".js" fixtures and the mocks look like:
taskMocks.js
/*global angular */
angular.module('taskMocks', ['ngMockE2E']).
factory('taskMocks', ['$httpBackend', function($httpBackend) {
'use strict';
var tasks_p1 = [ Factory.build('task'), Factory.build('task')],
tasks_p2 = [ Factory.build('task'), Factory.build('task')]
return {
register: function() {
$httpBackend.whenGET(..regex_for_url_for_page1..).respond(tasks_p1);
$httpBackend.whenGET(..regex_for_url_for_page2..).respond(tasks_p2);
}
};
}]);
To answer your question, yes there is a way to do it without involving a real server and you can use $httpBackend to mock responses in e2e tests, but it is not as straightforward as with mocking them in the unit tests. You also need to include angular-mocks.js in the index.html as well as 'ngMockE2E' in app.js.
