I want to retry if nightwatch does not click on an element. How can I do that?
I have the following code:
this.browser.isVisible('.signUp', function (result) {
if (result.value && result.length) {
for(var i = 0; i < 3; i += 1) {
this.browser.click(this.element.login.signInBtn);
var check = this.browser.url(function(result) {
// on login page
console.log(result);
if (result.value.indexOf("#login") !== -1) {
return false;
} else {
return true;
}
});
if (check) {
break;
}
}
}
}.bind(this));
-retries n will not run before and after function so this will not work as expected. You should try --suiteRetries n.
You can retry test cases with --retries command-line option. Example nightwatch --retries 2 will retry failed test case two additional times.
However I will not recommend you using that. I would first explore other options to make sure that element can be clicked. Like example waiting for it to become visible with waitForElementVisible
this.browser.waitForElementVisible(this.element.login.signInBtn, 1000);
Here is the updated Fiddle to test.
I am trying to setup grid with the in-line editing. Why saveRow method doesnt affect update function in transport definition and doesnt exit row from edit mode ?
Also please try to change var "can_edit" to false; Why this option doesn`t affect the field "day1"
If you debug your code for detecting the pressed key:
dataBound: function (o) {
...
o.sender.element.delegate('tbody>tr', 'keypress', function (e, o) {
if (!e.altKey && !e.ctrlKey && !e.shiftKey && e.key == "Enter") {
if ($(".k-grid-edit-row").length > 0) {
grid.saveRow();
}
}
});
}
You will see that you never get to grid.saveRow(). Try using e.keyCode instead:
if (!e.altKey && !e.ctrlKey && !e.shiftKey && e.keyCode == 13) {
...
}
I am using Selenium WebDriver for crawling a web site(only for example, I will be crawling other web sites too!) which has infinite scroll.
Problem statement:
Scroll down the infinite scroll page till the content stops loading using Selenium web driver.
My Approach:
Currently I am doing this-
Step 1: Scroll to the page bottom
JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("javascript:window.onload=toBottom();"+
"function toBottom(){" +
"window.scrollTo(0,Math.max(document.documentElement.scrollHeight," +
"document.body.scrollHeight,document.documentElement.clientHeight));" +
"}");
Then I wait for some time to let the Ajax Request complete like this-
Step 2: Explicitly wait for Ajax request to be over
Thread.sleep(1000);
Then I give another java script to check if the page is scrollable
Step 3:Check if the page is scrollable
//Alternative to document.height is to be used which is document.body.clientHeight
//refer to https://developer.mozilla.org/en-US/docs/DOM/document.height
if((Long)js.executeScript("return " +
"(document.body.clientHeight-(window.pageYOffset + window.innerHeight))")>0)
If the above condition is true then I repeat the from Step 1 - 3, till condition in Step 3 is false.
The Problem:
I do not want to give the Thread.sleep(1000); in step 2, rather I would like to check using Java Script if the background Ajax request is over and then scroll down further if the condition in Step 3 is true .
PS: I am not the developer of the page so I do not have access to the code running the page, I can just inject java scripts(as in Step 1 and 3) in the web page. And, I have to write a generic logic for any web site with Ajax requests during infinite scroll.
I will be grateful to some one could spare some time here!
EDIT : Ok, after struggling for 2 days, I have figured out that the pages which I am crawling through the Selenium WebDriver can have any of these JavaScript libraries and I will have to pool according to the different Library, for example, In case of the web application using jQuery api, I may be waiting for
(Long)((JavascriptExecutor)driver).executeScript("return jQuery.active")
to return a zero.
Likewise if the web application is using the Prototype JavaScript library I will have to wait for
(Long)((JavascriptExecutor)driver).executeScript("return Ajax.activeRequestCount")
to return a zero.
Now, the problem is how do I write a generic code which could handle most the JavaScript libraries available?
Problem I am facing in implementing this-
1. How do I find which JavaScript Library is being used in the Web Application(using Selenium WebDriver in Java), such that I can then write the corresponding wait methods?
Currently, I am using this
Code
2. This way I will have to write as many as 77 methods for separate JavaScript library so, I need a better way to handle this scenario as well.
In short, I need to figure out if the browser is making any call(Ajax or simple) with or without any JavaScript library through Selenium Web Driver's java implementation
PS: there are Add ons for Chorme's JavaScript Lib detector and Firefox's JavaScript Library detector which detect the JavaScript library being used.
For web pages with Ajax Response during the infinite scroll and using jQuery API(or other actions), before starting to opening the web page.
//Inject the pooling status variable
js.executeScript("window.status = 'fail';");
//Attach the Ajax call back method
js.executeScript( "$(document).ajaxComplete(function() {" +
"status = 'success';});");
Step 1: will remain the same as in the original question
Step 2 Pooling the following script(This is the one which removes the need of Thread.Sleep() and makes the logic more dynamic)
String aStatus = (String)js.executeScript("return status;");
if(aStatus!=null && aStatus.equalsIgnoreCase("success")){
js.executeScript("status = 'fail';");
break poolingLoop;
}
Step 3: No need now!
Conclusion: No need to give blunt Thread.sleep(); again and again while using Selenium WebDriver!!
This approach works good only if there's jQuery api being used in the web application.
EDIT:
As per the the link given by #jayati i injected the javascript-
Javascript one:
//XMLHttpRequest instrumentation/wrapping
var startTracing = function (onnew) {
var OldXHR = window.XMLHttpRequest;
// create a wrapper object that has the same interfaces as a regular XMLHttpRequest object
// see http://www.xulplanet.com/references/objref/XMLHttpRequest.html for reference on XHR object
var NewXHR = function() {
var self = this;
var actualXHR = new OldXHR();
// private callbacks (for UI):
// onopen, onsend, onsetrequestheader, onupdate, ...
this.requestHeaders = "";
this.requestBody = "";
// emulate methods from regular XMLHttpRequest object
this.open = function(a, b, c, d, e) {
self.openMethod = a.toUpperCase();
self.openURL = b;
ajaxRequestStarted = 'open';
if (self.onopen != null && typeof(self.onopen) == "function") {
self.onopen(a,b,c,d,e); }
return actualXHR.open(a,b,c,d,e);
}
this.send = function(a) {
ajaxRequestStarted = 'send';
if (self.onsend != null && typeof(this.onsend) == "function") {
self.onsend(a); }
self.requestBody += a;
return actualXHR.send(a);
}
this.setRequestHeader = function(a, b) {
if (self.onsetrequestheader != null && typeof(self.onsetrequestheader) == "function") { self.onsetrequestheader(a, b); }
self.requestHeaders += a + ":" + b + "\r\n";
return actualXHR.setRequestHeader(a, b);
}
this.getRequestHeader = function() {
return actualXHR.getRequestHeader();
}
this.getResponseHeader = function(a) { return actualXHR.getResponseHeader(a); }
this.getAllResponseHeaders = function() { return actualXHR.getAllResponseHeaders(); }
this.abort = function() { return actualXHR.abort(); }
this.addEventListener = function(a, b, c) { return actualXHR.addEventListener(a, b, c); }
this.dispatchEvent = function(e) { return actualXHR.dispatchEvent(e); }
this.openRequest = function(a, b, c, d, e) { return actualXHR.openRequest(a, b, c, d, e); }
this.overrideMimeType = function(e) { return actualXHR.overrideMimeType(e); }
this.removeEventListener = function(a, b, c) { return actualXHR.removeEventListener(a, b, c); }
// copy the values from actualXHR back onto self
function copyState() {
// copy properties back from the actual XHR to the wrapper
try {
self.readyState = actualXHR.readyState;
} catch (e) {}
try {
self.status = actualXHR.status;
} catch (e) {}
try {
self.responseText = actualXHR.responseText;
} catch (e) {}
try {
self.statusText = actualXHR.statusText;
} catch (e) {}
try {
self.responseXML = actualXHR.responseXML;
} catch (e) {}
}
// emulate callbacks from regular XMLHttpRequest object
actualXHR.onreadystatechange = function() {
copyState();
try {
if (self.onupdate != null && typeof(self.onupdate) == "function") { self.onupdate(); }
} catch (e) {}
// onreadystatechange callback
if (self.onreadystatechange != null && typeof(self.onreadystatechange) == "function") { return self.onreadystatechange(); }
}
actualXHR.onerror = function(e) {
ajaxRequestComplete = 'err';
copyState();
try {
if (self.onupdate != null && typeof(self.onupdate) == "function") { self.onupdate(); }
} catch (e) {}
if (self.onerror != null && typeof(self.onerror) == "function") {
return self.onerror(e);
} else if (self.onreadystatechange != null && typeof(self.onreadystatechange) == "function") {
return self.onreadystatechange();
}
}
actualXHR.onload = function(e) {
ajaxRequestComplete = 'loaded';
copyState();
try {
if (self.onupdate != null && typeof(self.onupdate) == "function") { self.onupdate(); }
} catch (e) {}
if (self.onload != null && typeof(self.onload) == "function") {
return self.onload(e);
} else if (self.onreadystatechange != null && typeof(self.onreadystatechange) == "function") {
return self.onreadystatechange();
}
}
actualXHR.onprogress = function(e) {
copyState();
try {
if (self.onupdate != null && typeof(self.onupdate) == "function") { self.onupdate(); }
} catch (e) {}
if (self.onprogress != null && typeof(self.onprogress) == "function") {
return self.onprogress(e);
} else if (self.onreadystatechange != null && typeof(self.onreadystatechange) == "function") {
return self.onreadystatechange();
}
}
if (onnew && typeof(onnew) == "function") { onnew(this); }
}
window.XMLHttpRequest = NewXHR;
}
window.ajaxRequestComplete = 'no';//Make as a global javascript variable
window.ajaxRequestStarted = 'no';
startTracing();
Or Javascript Two:
var startTracing = function (onnew) {
window.ajaxRequestComplete = 'no';//Make as a global javascript variable
window.ajaxRequestStarted = 'no';
XMLHttpRequest.prototype.uniqueID = function() {
if (!this.uniqueIDMemo) {
this.uniqueIDMemo = Math.floor(Math.random() * 1000);
}
return this.uniqueIDMemo;
}
XMLHttpRequest.prototype.oldOpen = XMLHttpRequest.prototype.open;
var newOpen = function(method, url, async, user, password) {
ajaxRequestStarted = 'open';
/*alert(ajaxRequestStarted);*/
this.oldOpen(method, url, async, user, password);
}
XMLHttpRequest.prototype.open = newOpen;
XMLHttpRequest.prototype.oldSend = XMLHttpRequest.prototype.send;
var newSend = function(a) {
var xhr = this;
var onload = function() {
ajaxRequestComplete = 'loaded';
/*alert(ajaxRequestComplete);*/
};
var onerror = function( ) {
ajaxRequestComplete = 'Err';
/*alert(ajaxRequestComplete);*/
};
xhr.addEventListener("load", onload, false);
xhr.addEventListener("error", onerror, false);
xhr.oldSend(a);
}
XMLHttpRequest.prototype.send = newSend;
}
startTracing();
And checking the status of the status vars ajaxRequestStarted, ajaxRequestComplete in the java code, one can determine if the ajax was started or completed.
Now I have a way to wait till an Ajax is complete, I can also find if the Ajax was triggered on some action
Approach 1:
Your approach is good, just a few changes would do the trick:
Step 1: Improve this step to call the toBottom function at regular interval using window.setInterval. At (c >= totalcount) call window.clearInterval
Setp 2: Instead of checking the page is yet scrollable, check if (c >= totalcount). And this condition every 200ms until (c >= totalcount) returns true.
FYI: If the Step 1 doesn't work in all the browsers then probably, you can refer to line 5210 of Tata-Nano-Reviews-925076578.js and call this with cvariable checking.
Approach 2:
Go to jQuery API and type "ajax". You can find some callback handlers which could be used for ajax requests.
Probably, set a variable before the request is been sent and after it is been received appropriately.
And in between use your original method of scrolling to bottom at regular interval, unless you can no more scroll. At this point clear the interval variable.
Now, regularly check if that interval variable is null or not. Null would mean that you have reached the bottom.
We had to solve the same problem, and managed using a long Javascript function. Just need to add checks to see which library is not undefined.
PS Thanks for giving me an easy answer for how to check for in progress Prototype requests!
eg. Handle JQuery and XHR/Prototype
var jsExecutor = /*Get your WebDriverInstance*/ as IJavaScriptExecutor;
while(/*your required timeout here*/)
{
var ajaxComplete =
jsExecutor.ExecuteScript("return ((typeof Ajax === 'undefined') ||
Ajax.activeRequestCount == 0) && ((typeof jQuery === 'undefined') || $.active == 0)");
if (ajaxIsComplete)
return
}
I'm loading a page into a div. I'm also attempting to establish a waypoint, so that when the user scrolls down the page, the menu will change colors.
The problem I am having is the new height of the div is not recognized by the browser once the ajax content is loaded.
Here's what I have:
$(".cta").live('click', function () {
$('#faq').load('about-us/faqs/index.html'),
function () {
$("#faq").waypoint(function (event, direction) {
if (direction === 'up') {
$("#siteNav li a").removeClass("siteNavSelected");
$("#siteNav li.nav3 a").addClass("siteNavSelected");
}
}, {
offset: function () {
return $.waypoints('viewportHeight') - $("#faq").outerHeight();
}
});
}
return false;
});
Any ideas? Thanks.
Use $.waypoints('refresh');, from the documentation:
This will force a recalculation of each waypoint’s trigger point based on its offset option. This is called automatically whenever the window is resized or new waypoints are added. If your project is changing the DOM or page layout without doing one of these things, you may want to manually call it.
I'm not familiar with the intrinsics of the waypoint plugin, but you could also bind a scroll event and then capture the .scrollTop() value. Would look something like this:
$(document).bind('scroll', function(event) {
var scrollTop = $(window).scrollTop();
if (scrollTop < 1000 && $('siteNav li').hasClass('styleA')) { return; }
else {
$('siteNav li').removeClass('styleB');
$('siteNav li').addClass('styleA');
}
if (scrollTop > 1000 && $('siteNav li').hasClass('styleB')) { return; }
else {
$('siteNav li').removeClass('styleA');
$('siteNav li').addClass('styleB');
}
});
You have to play with the values a little to get it acting at the right spot. Also you have to use a greater or less than value in the test as if a user is at the top of the page and uses the scroll-wheel on his mouse to fly down the page, you don't get every value in between.
I am having trouble with animating my sprite in Java ME.
if ((k & FIRE_PRESSED) != 0) {
spriteActive = true;
boxer.nextFrame();
if (boxer.getFrame() == boxer.getFrameSequenceLength() - 6) {
spriteActive = false;
}
}
}
// TO re-start a game...
public void update() {
if(boxer.getRawFrameCount() == 5 && spriteActive == false){
boxer.setFrame(0);
}
}
When the enter key is pressed, spriteActive is set true but only changes the frame by one. I intend to have it animating the entire sequence but it is not doing that. Just animates 1 frame at a time with every press.
Does anyone have any ideas/advice of how I should approach this?
Thanks for the time and help!
Do you have any code that checks whether spriteActive is true and then sets the next frame?
I am no expert on Java but I would suspect you'd need to implement something like this:
if (spriteActive == true)
{
boxer.nextFrame();
}
