I am trying to test a flow
1.Ajax Request > Loader is visible
2.Response Received > a.Loader is hidden
b.Redirect to another page(where a interstitial is visible)
White testing them with casperJS I use the waitFor method, something like this.
casper.waitFor(function check() {
return this.evaluate(function() {
return $("#loader").is(":hidden");
});
}, function then() {
this.test.pass("Ajax request");
this.waitDone();
}, function timeout() { // step to execute if check has failed
this.echo("Timeout: page did not load in time...").exit();
},4000);
The thing is even if the condition is passed in check, then is not executed until the page is not redirected(read the flow, I am trying to test) and the test suite won't move to the next step.
Is there something I am missing here ?
Make sure your reference 'this' is located within a casper block:
casper.then(function() {
this.waitFor(function check() {
Possible quick fix without knowing more detail. Pass jQuery variable to evaluate.
this.evaluate(function($) {
You could also try:
casper.waitWhileVisible('#loader', function() {
// executes when #loader is hidden
});

Lets say we have a form with a jquery validation. Now we create a simple Jasmine spec and want to test if the error message is visible if we submit an empty form.
My first step is to trigger the submit form event after that jquery validate will work and show the error messages. The time window until the error message will be displayed is really small (2ms) but too big for a Jasmine test. Currently with a setTimeout() it works but I think that is a bad way :(
I am new to Jasmine and I think there must be a better way? Something with spy?
Dummy spec for example:
describe("Lorem Impsum: ", function () {
it("Form validation shows error messages.", function () {
$("#MyForm").submit();
expect($(".error")).toBeVisible();
});
});
Using setTimeout or setInterval for polling may not be a bad way. If the page is complicated, periodic checks are simpler, than using MutationObserver. (This is a unit test; not an application.) If you choose the polling interval short enough, the test will not be so slow. For example:
describe("Lorem Impsum: ", function () {
it("Form validation shows error messages.", function (done) {
$("#MyForm").submit();
waitForElement(".error", function () {
expect($(".error")).toBeVisible();
done();
});
});
});
function waitForElement(selector, callback) {
var interval;
if ($(selector).length) {
callback();
} else {
interval = setInterval(function () {
if ($(selector).length) {
clearInterval(interval);
callback();
}
}, 10);
}
}
You will need to declare and call the done callback, so that Jasmine gets notified, when the test spec has finished.
I am experimenting with the new way of handling page events in jqM and have run into a curious issue. When handling the pagecontainerbeforechange event
$(document).on('pagecontainerbeforechange',function(e,u){test(e,u,'changing');})
function test(e,u,msg){console.log($(u.toPage));}
Attempting to put a jQuery object wrapper around u.toPage - as done above - produces strange behavior.
Check out this fiddle to see what I mean
Click on the Second Page button and then view the console. Nothing will happen (the second page is not shown) and you will see a message along the lines of *Uncaught error:syntax error, unrecognized expression http://jsfiddle.net/egn7g5xb/1/show/#second
Now comment out Line 7 and run the fiddle again. No such issue this time and the second page gets shown.
Perhaps someone here might be able to explain what is going on here?
On initial run, jQuery Mobile creates a fake page before navigating to first page in DOM. At that stage, pagecontainerbeforechange fires twice and returns .toPage as an object.
Later on, upon navigating to other pages, it fires twice again; however, it returns a string first time (URL/hash) and second time it returns an object which is the page itself.
Therefore, when using that event, you have to determine whether .toPage is an object or a string.
$(document).on("pagecontainerbeforechange", function (e, data) {
if (typeof data.toPage == "string") {
/* parse url */
}
if (typeof data.toPage == "object") {
/* manipulate page navigating to */
}
});
Note that pagecontainerbeforetransition is similar to beforechange, however, it fires once and returns .toPage as an object.
First, create your pagecontainer events within $(document).on("pagecreate", "#first", function(){ .. }).
Then the selector for these events should be $(":mobile-pagecontainer") or $("body") NOT $(document).
function test(e,u,msg)
{
console.log(msg);
var IsJQ = u.toPage instanceof $;
console.log(IsJQ);
if (IsJQ){
console.log(u.toPage.data());
} else {
console.log(u.toPage);
}
console.log('---');
}
$(document).on("pagecreate", "#first", function(){
$(":mobile-pagecontainer").on('pagecontainerbeforechange', function (e, u) {
test(e,u,'changing');
});
$(":mobile-pagecontainer").on('pagecontainerchange',function(e,u){
test(e,u,'changed');
});
});
Updated FIDDLE
In a test spec, I need to click a button on a web page, and wait for the new page completely loaded.
emailEl.sendKeys('jack');
passwordEl.sendKeys('123pwd');
btnLoginEl.click();
// ...Here need to wait for page complete... How?
ptor.waitForAngular();
expect(ptor.getCurrentUrl()).toEqual(url + 'abc#/efg');
Depending on what you want to do, you can try:
browser.waitForAngular();
or
btnLoginEl.click().then(function() {
// do some stuff
});
to solve the promise. It would be better if you can do that in the beforeEach.
NB: I noticed that the expect() waits for the promise inside (i.e. getCurrentUrl) to be solved before comparing.
I just had a look at the source - Protractor is waiting for Angular only in a few cases (like when element.all is invoked, or setting / getting location).
So Protractor won't wait for Angular to stabilise after every command.
Also, it looks like sometimes in my tests I had a race between Angular digest cycle and click event, so sometimes I have to do:
elm.click();
browser.driver.sleep(1000);
browser.waitForAngular();
using sleep to wait for execution to enter AngularJS context (triggered by click event).
You don't need to wait. Protractor automatically waits for angular to be ready and then it executes the next step in the control flow.
With Protractor, you can use the following approach
var EC = protractor.ExpectedConditions;
// Wait for new page url to contain newPageName
browser.wait(EC.urlContains('newPageName'), 10000);
So your code will look something like,
emailEl.sendKeys('jack');
passwordEl.sendKeys('123pwd');
btnLoginEl.click();
var EC = protractor.ExpectedConditions;
// Wait for new page url to contain efg
ptor.wait(EC.urlContains('efg'), 10000);
expect(ptor.getCurrentUrl()).toEqual(url + 'abc#/efg');
Note: This may not mean that new page has finished loading and DOM is ready. The subsequent 'expect()' statement will ensure Protractor waits for DOM to be available for test.
Reference: Protractor ExpectedConditions
In this case, you can used:
Page Object:
waitForURLContain(urlExpected: string, timeout: number) {
try {
const condition = browser.ExpectedConditions;
browser.wait(condition.urlContains(urlExpected), timeout);
} catch (e) {
console.error('URL not contain text.', e);
};
}
Page Test:
page.waitForURLContain('abc#/efg', 30000);
I typically just add something to the control flow, i.e.:
it('should navigate to the logfile page when attempting ' +
'to access the user login page, after logging in', function() {
userLoginPage.login(true);
userLoginPage.get();
logfilePage.expectLogfilePage();
});
logfilePage:
function login() {
element(by.buttonText('Login')).click();
// Adding this to the control flow will ensure the resulting page is loaded before moving on
browser.getLocationAbsUrl();
}
Use this I think it's better
*isAngularSite(false);*
browser.get(crmUrl);
login.username.sendKeys(username);
login.password.sendKeys(password);
login.submit.click();
*isAngularSite(true);*
For you to use this setting of isAngularSite should put this in your protractor.conf.js here:
global.isAngularSite = function(flag) {
browser.ignoreSynchronization = !flag;
};
to wait until the click itself is complete (ie to resolve the Promise), use await keyword
it('test case 1', async () => {
await login.submit.click();
})
This will stop the command queue until the click (sendKeys, sleep or any other command) is finished
If you're lucky and you're on angular page that is built well and doesn't have micro and macro tasks pending then Protractor should wait by itself until the page is ready. But sometimes you need to handle waiting yourself, for example when logging in through a page that is not Angular (read how to find out if page has pending tasks and how to work with non angular pages)
In the case you're handling the waiting manually, browser.wait is the way to go. Just pass a function to it that would have a condition which to wait for. For example wait until there is no loading animation on the page
let $animation = $$('.loading');
await browser.wait(
async () => (await animation.count()) === 0, // function; if returns true it stops waiting; can wait for anything in the world if you get creative with it
5000, // timeout
`message on timeout`
);
Make sure to use await
you can do something like this
emailEl.sendKeys('jack');
passwordEl.sendKeys('123pwd');
btnLoginEl.click().then(function(){
browser.wait(5000);
});
browser.waitForAngular();
btnLoginEl.click().then(function() { Do Something });
to solve the promise.
I'm triyng to build a simple animation jQuery-plugin. The main idea is to take an element and manipulate it in some way repeatedly in a fixed intervall which would be the fps of the animation.
I wanted to accomplish this through events. Instead of using loops like for() or while() I want to repeat certain actions through triggering events. The idea behind this: I eventualy want to be able to call multiple actions on certain events, like starting a second animation when the first is done, or even starting it when one animation-sequence is on a certain frame.
Now I tried the following (very simplified version of the plugin):
(function($) {
$.fn.animation = function() {
obj = this;
pause = 1000 / 12; //-> 12fps
function setup(o) {
o.doSomething().trigger('allSetUp');
}
function doStep(o, dt) {
o.doSomething().delay(dt).trigger('stepDone');
}
function sequenceFinished(o) {
o.trigger('startOver');
}
function checkProgress(o) {
o.on({
'allSetup': function(event) {
console.log(event); //check event
doStep(o, pause);
},
'stepDone': function(event) {
console.log(event); //check event
doStep(o, pause);
},
'startOver': function(event) {
console.log(event); //check event
resetAll(o);
}
});
}
function resetAll(o) {
/*<-
reset stuff here
->*/
//then start over again
setup(o);
}
return this.each(function() {
setup(obj);
checkProgress(obj);
});
};
})(jQuery);
Then i call the animation like this:
$(document).ready(function() {
$('#object').animation();
});
And then – nothing happens. No events get fired. My question: why? Is it not possible to use events like this inside of a jQuery plugin? Do I have to trigger them 'manualy' in $(document).ready() (what I would not prefer, because it would be a completely different thing – controling the animation from outside the plugin. Instead I would like to use the events inside the plugin to have a certain level of 'self-control' inside the plugin).
I feel like I'm missing some fundamental thing about custom events (note: I'm still quite new to this) and how to use them...
Thx for any help.
SOLUTION:
The event handling and triggering actually works, I just had to call the checkProgress function first:
Instead of
return this.each(function() {
setup(obj);
checkProgress(obj);
});
I had to do this:
return this.each(function() {
checkProgress(obj);
setup(obj);
});
So the event listening function has to be called before any event gets triggered, what of course makes perfect sense...
You need set event on your DOM model for instance:
$('#foo').bind('custom', function(event, param1, param2) {
alert('My trigger')
});
$('#foo').on('click', function(){ $(this).trigger('custom');});
You DOM element should know when he should fire your trigger.
Please note that in your plugin you don't call any internal function - ONLY DECLARATION
I am using jConfirm for confirm dialog with success.
For first time i tried to call it inside the ajax success but seems to fail.
Here is the code:
success: function (j) {
if(j.status)
{
jConfirm('File Already exist.Are you sure you want to replace ?', 'File Exist', function(r) {
if (r==true)
{ }
else
{
//code for cancel
}
});
}
}//success
The problem is that the dialog is show but does not wait for user answer and continues.
When change to classic javascript confirm everything works fine!
jConfirm is an asynchronous method.
As you've noticed, it returns immediately, without waiting for the user to close the dialog.
You need to put all of your code in the jConfirm callback.
