Cypress: Check if element exists & throw an exception when element doesn't - testing

I'm trying to check if an element exists or not. If the element exists, I want to click on the button X, I want to click on the button Y.
However, when the element does not exist Cypress throws an exception and it stops the test.
Code Sample:
let elementKey = '#up-picker'
Cypress.get('body').then($res=>{
if($res.find(elementKey).length>0){
// click on button X
}else{
// click on button Y
}
})
I have an element with this id, but sometimes because the logic in the UI changes it, Cypress can find this element.
I checked more posts in Stackoverflow and no answer works for me.

What's working for my tests (close to your example):
cy.get('body').then($body => {
if ($body.find('your-selector').length) {
// do stuff
}
});

How to get Position of button in selenium c#

One Video is there below that one button is there i need to automate that button wheather that button is present below that video or not any one please help me to resolve this
If the button is a part of the page DOM and it can be searched by Selenium you should be able to access it's Location property like:
System.Drawing.Point location = driver.FindElement(By.XPath("//your_element_locator")).Location;
Console.WriteLine("My element location: " + location);
If you want to conditionally execute this or that code block depending on presence/absence of the element you can go for FindElements() function like
if (driver.FindElements(By.XPath("//your_element_locator")).Count > 0)
{
// element is present
}
else
{
//element is absent
}
If the button is not present in the DOM and it's a part of video - you will have to go for image recognition frameworks like AForge.NET, Emgu CV or SeeTest

chromeless- Clicking on an element in the next page is not working

On one of my tests I log in and move to the next page.
In the next page when I try to click on the profile element with .click nothing seems to be happening.
When I use the .exists function it returns false.
Why can't chromeless recognize element after changing the DOM?
async func(){
try {
this.chromeless
.goto(this.url)
.click(this.switchToLogIn)
.type(this.email, this.emaillAddressInput)
.type(this.password, this.passwordInput)
.click(this.logInButton )
.click(this.myProfile)
.screenshot()
}
catch(err) {
console.log(err)
}
Anything that was not already available in the DOM tree when the previous action in the chain was performed (with the exception of goto() and possibly some other methods) has to be waited for using the wait() method.
So, assuming that this.myProfile is a CSS selector string for an element to be clicked:
// Unchanged code omitted
.click(this.logInButton)
// Since the previous click loads a new page and/or shows new content, we need to wait
.wait(this.myProfile)
.click(this.myProfile)
Alternatively, the implicitWait Chromeless constructor option could be set to true, as long as that does not affect anything else negatively.

Visibility of element- selenium webdriver

My script creates a new article: fills few fields and click "Submit button" at end of page.
I have written Click() function in util class like :
public void click(String xpathKey)
{
WebElement myDynamicElement = (new WebDriverWait(driver, 60))
.until(ExpectedConditions.visibilityOfElementLocated(
By.cssSelector(prop.getProperty(xpathKey))));
try
{
myDynamicElement.click();
}
catch (Exception e)
{
e.printStackTrace();
throw e;
}
}
Waiting for visibility of element means it will wait until element will be visible on the page or on screen? My script clicks on submit button while it's not exactly visible on the page.
I am running this script since months and it's running perfectly fine. Suddenly it started giving error element is not clickable at point(213, 415). It never appeared before. Anyone has an idea, why it could have happened?
I have done many cases, where the element is not exactly visible, generally button at end of page. selenium does not scroll itself, it finds the element and performs operation.
Try this.
public void click(String xpathKey)
{
WebElement myDynamicElement = (new WebDriverWait(driver, 60))
.until(ExpectedConditions.visibilityOfElementLocated(
By.cssSelector(prop.getProperty(xpathKey))));
try
{
Actions act = new Actions(driver);
act.moveToElement(myDynamicElement);
act.click();
act.build().perform();
}
catch (Exception e)
{
e.printStackTrace();
throw e;
}
}
The error message you are getting indicates that there is an element covering the element you are trying to click. If you read the error message carefully, it will tell you the HTML of the blocking element and that will help you find it on the page. Without more info, it's hard to tell exactly what the situation is but there are a few common causes.
You may have just closed a dialog/popup and it's not quite completely gone before you try to click. In this case, wait for some element that's part of the dialog to be invisible generally solves this problem.
There may be some wait/loading/spinner control that appears and disappears but you are clicking before it's completely gone. The solution is the same as #1, wait for some element that's part of the spinner to be invisible.
There may be some UI element like a header, footer, sidebar that is floating that covers the element you are trying to click if it's at the very bottom/top/etc of the page. These can be a real pain because you never know when the elements are going to align and be covered. One solution is to use JS to scroll the page a little more. For example, if you script is at the top of the page and you want to click something at the bottom. Doing a click will scroll the page to show that element but that puts the element at the very bottom of the page and under a floating footer. You try to click but catch the exception. Since you know you're at the bottom of the page, you scroll the page downwards by X pixels. This brings your desired element out from behind the floating footer and now you can click it.
NOTE: If you are going to click an element right after waiting for it, you should use .elementToBeClickable(locator) instead of .visibilityOfElementLocated(). It won't solve your current problem but it's a more complete and proper wait for what you are wanting to do.

stale element exception : click on report link in page then back button and so on

AS shown in the image : i want to click on each link one by one , on clicking :window does not gets change but it refresh.
clicking in the report link navigate to the next page, where clicking on back link it navigates back to the same page.
once it take back to the same page , locator no longer identify the next report link & throws stale element exception
public void getreports(String reportname) throws Exception
List<WebElement> li=driver.findElements(By.xpath(".//tbody/tr/th/following::
tr/td//div/a"));
for(WebElement e: li) {
if(reportname.equalsIgnoreCase(e.getText())) {
utilities.wait_control(e);
e.click();
break;
}
else if(reportname.equalsIgnoreCase("all"))
{
utilities.wait_control(e);
e.click();
NetReports ld = PageFactory.initElements(driver, NetReports .class);
ld.Netsubcategoryreport_backbutton.click();
Thread.sleep(2000);
} }
I think you just need a small adjustment to your loop:
String selector = ".//tbody/tr/th/following::tr/td//div/a";
List<WebElement> li=driver.findElements(By.xpath(selector));
for (int i = 0; i < li.length; i++) {
li=driver.findElements(By.xpath(selector));
WebElement e = li.get(i);
//Rest of your logic goes here
}
StaleElementReferenceException -
As the name suggests this exception occurs when the element stale, which means the element reference on which you are trying to take a action upon is no longer available on the page or has changed. 
To avoid this exception, try to find the element as and when you need to
take an action upon it rather than getting the element at some point of code
and then reusing it at different places.

Dojo:how to find if the widget has focus in dojo

how do I find out if my custom widget has focus in Dojo?
i have dojo editor i wnat to know if the editor has already focus or not?
you can use the module dijit/focus to find out the focus
FROM DOJO DOCS
Tracking active widgets
At any point in time there is a set of (for lack of a better word)
“active” or “focused” widgets, meaning the currently focused widget
and that widget’s ancestors. “Ancestor” can mean either DOM ancestor
(ex: TextBox –> Form), or a logical parent-child relationship (ex:
TooltipDialog –> DropDownButton).
For example, if focus is on a TextBox inside a TabContainer inside a
TooltipDialog triggered by a DropDownButton, the stack would be
TextBox –> ContentPane –> TabContainer –> TooltipDialog –>
DropDownButton.
The activeStack[] parameter indicates this set of widgets, and an app
can monitor changes to activeStack[] by:
require([ "dijit/focus" ], function(focusUtil){
focusUtil.watch("activeStack", function(name, oldValue, newValue){
console.log("Focused widget + ancestors: ", newValue.join(", "));
});
});
the question in title has a different answer than the one in the descriptions.
there are two ways achieving the question in the title, by using dojo's focusUtil ("dijit/focus"). both ways give you something that you could find the widget using it and the dijit's registry ("dijit/registry").
focusUtil.curNode: gives you the DOM Node that currently has the focus. the function below, you could get the widget reference.
function getWidgetByNode(node){
var result;
while (!result && node){
result = registry.byNode(node);
if (node.parentElement)
node = node.parentElement;
else
node = null;
}
return result;
}
var focusedWidget = getWidgetByNode(focusUtil.curNode)
focusUtil.activeStack: gives you an array of the widgets (parent to child) that has the focus. so the last item in the array is the direct widget which has the focus. index values are widget ids, so you should get the widget by the following code
var focusedWidgetId = focusUtil.activeStack[focusUtil.activeStack.length-1];
var focusedWidget = registry.byId(focusedWidgetId);
now if you want to know if the currently focused widget is some specific one, it depends on what you have in hands from that specific widget:
widget itself: like the return values of above samples. now you have to compare if these are the same thing. you can not compare two widget objects using the == operator. you could compare their ids like this:
myWidget.id == focusedWidget.id
widget's id: this way you just easily get the id of the current node from focusUtil and compare it with the id you have liek this:
myWidgetId == focusedWidgetId
references:
http://dojotoolkit.org/reference-guide/1.9/dijit/focus.html
http://dojotoolkit.org/reference-guide/1.9/dijit/registry.html
require([ "dijit/focus" ], function(focusUtil){
var activeElement = focusUtil.curNode; // returns null if there is no focused element
});
check blow url here you can see some examples
http://dojotoolkit.org/reference-guide/1.8/dijit/focus.html#dijit-focus
a) For dojo 1.6: call dijit.getFocus(). This will return an object containing the currently focused dom node, among other things (selected text, etc.). To get the corresponding widget, simply do:
var activeElement = dijit.getEnclosingWidget(dijit.getFocus().node);
This is the full reference for dijit.getFocus(), from the source code:
// summary:
// Called as getFocus(), this returns an Object showing the current focus
// and selected text.
//
// Called as getFocus(widget), where widget is a (widget representing) a button
// that was just pressed, it returns where focus was before that button
// was pressed. (Pressing the button may have either shifted focus to the button,
// or removed focus altogether.) In this case the selected text is not returned,
// since it can't be accurately determined.
//
// menu: dijit._Widget or {domNode: DomNode} structure
// The button that was just pressed. If focus has disappeared or moved
// to this button, returns the previous focus. In this case the bookmark
// information is already lost, and null is returned.
//
// openedForWindow:
// iframe in which menu was opened
//
// returns:
// A handle to restore focus/selection, to be passed to `dijit.focus`.
b) For dojo 1.7 and up, use dijit/focus:
require([ "dijit/focus" ], function(focusUtil) {
var activeElement = focusUtil.curNode; // returns null if there is no focused element
});
