Check if element is clickable in Selenium Java - java

I'm new to Selenium and need to check if element is clickable in Selenium Java, since element.click() passes both on link and label.
I tried using the following code, but it is not working:
WebDriverWait wait = new WebDriverWait(Scenario1Test.driver, 10);
if(wait.until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[#id='brandSlider']/div[1]/div/div/div/img)[50]")))==null)

elementToBeClickable is used for checking an element is visible and enabled such that you can click it.
ExpectedConditions.elementToBeClickable returns WebElement if expected condition is true otherwise it will throw TimeoutException, It never returns null.
So if your using ExpectedConditions.elementToBeClickable to find an element which will always gives you the clickable element, so no need to check for null condition, you should try as below :-
WebDriverWait wait = new WebDriverWait(Scenario1Test.driver, 10);
WebElement element = wait.until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[#id='brandSlider']/div[1]/div/div/div/img)[50]")));
element.click();
As you are saying element.click() passes both on link and label that's doesn't mean element is not clickable, it means returned element clicked but may be there is no event performs on element by click action.
Note:- I'm suggesting you always try first to find elements by id, name, className and other locator. if you faced some difficulty to find then use cssSelector and always give last priority to xpath locator because it is slower than other locator to locate an element.
Hope it helps you..:)

There are instances when element.isDisplayed() && element.isEnabled() will return true but still element will not be clickable, because it is hidden/overlapped by some other element.
In such case, Exception caught is:
org.openqa.selenium.WebDriverException: unknown error: Element is not
clickable at point (781, 704). Other element would receive the click:
<div class="footer">...</div>
Use this code instead:
WebElement element=driver.findElement(By.xpath"");
JavascriptExecutor ex=(JavascriptExecutor)driver;
ex.executeScript("arguments[0].click()", element);
It will work.

wait.until(ExpectedConditions) won't return null, it will either meet the condition or throw TimeoutException.
You can check if the element is displayed and enabled
WebElement element = driver.findElement(By.xpath);
if (element.isDisplayed() && element.isEnabled()) {
element.click();
}

There are certain things you have to take care:
WebDriverWait inconjunction with ExpectedConditions as elementToBeClickable() returns the WebElement once it is located and clickable i.e. visible and enabled.
In this process, WebDriverWait will ignore instances of NotFoundException that are encountered by default in the until condition.
Once the duration of the wait expires on the desired element not being located and clickable, will throw a timeout exception.
The different approach to address this issue are:
To invoke click() as soon as the element is returned, you can use:
new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[#id='brandSlider']/div[1]/div/div/div/img)[50]"))).click();
To simply validate if the element is located and clickable, wrap up the WebDriverWait in a try-catch{} block as follows:
try {
new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[#id='brandSlider']/div[1]/div/div/div/img)[50]")));
System.out.println("Element is clickable");
}
catch(TimeoutException e) {
System.out.println("Element isn't clickable");
}
If WebDriverWait returns the located and clickable element but the element is still not clickable, you need to invoke executeScript() method as follows:
WebElement element = new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[#id='brandSlider']/div[1]/div/div/div/img)[50]")));
((JavascriptExecutor)driver).executeScript("arguments[0].click();", element);

From the source code you will be able to view that, ExpectedConditions.elementToBeClickable(), it will judge the element visible and enabled, so you can use isEnabled() together with isDisplayed(). Following is the source code.
public static ExpectedCondition<WebElement> elementToBeClickable(final WebElement element) {
return new ExpectedCondition() {
public WebElement apply(WebDriver driver) {
WebElement visibleElement = (WebElement) ExpectedConditions.visibilityOf(element).apply(driver);
try {
return visibleElement != null && visibleElement.isEnabled() ? visibleElement : null;
} catch (StaleElementReferenceException arg3) {
return null;
}
}
public String toString() {
return "element to be clickable: " + element;
}
};
}

the class attribute contains disabled when the element is not clickable.
WebElement webElement = driver.findElement(By.id("elementId"));
if(!webElement.getAttribute("class").contains("disabled")){
webElement.click();
}

List<WebElement> wb=driver.findElements(By.xpath(newXpath));
for(WebElement we: wb){
if(we.isDisplayed() && we.isEnabled())
{
we.click();
break;
}
}
}

Selenium in Java - can't go to the next page [duplicate]

I am trying to make some tests using selenium based Katalon Studio. In one of my tests I have to write inside a textarea. The problem is that I get the following error:
...Element MyElement is not clickable at point (x, y)... Other element would receive the click...
In fact my element is place inside some other diva that might hide it but how can I make the click event hit my textarea?
Element ... is not clickable at point (x, y). Other element would receive the click" can be caused for different factors. You can address them by either of the following procedures:
Element not getting clicked due to JavaScript or AJAX calls present
Try to use Actions Class:
WebElement element = driver.findElement(By.id("id1"));
Actions actions = new Actions(driver);
actions.moveToElement(element).click().build().perform();
Element not getting clicked as it is not within Viewport
Try to use JavascriptExecutor to bring the element within Viewport:
JavascriptExecutor jse1 = (JavascriptExecutor)driver;
jse1.executeScript("scroll(250, 0)"); // if the element is on top.
jse1.executeScript("scroll(0, 250)"); // if the element is at bottom.
Or
WebElement myelement = driver.findElement(By.id("id1"));
JavascriptExecutor jse2 = (JavascriptExecutor)driver;
jse2.executeScript("arguments[0].scrollIntoView()", myelement);
The page is getting refreshed before the element gets clickable.
In this case induce some wait.
Element is present in the DOM but not clickable.
In this case add some ExplicitWait for the element to be clickable.
WebDriverWait wait2 = new WebDriverWait(driver, 10);
wait2.until(ExpectedConditions.elementToBeClickable(By.id("id1")));
Element is present but having temporary Overlay.
In this case induce ExplicitWait with ExpectedConditions set to invisibilityOfElementLocated for the Overlay to be invisible.
WebDriverWait wait3 = new WebDriverWait(driver, 10);
wait3.until(ExpectedConditions.invisibilityOfElementLocated(By.xpath("ele_to_inv")));
Element is present but having permanent Overlay.
Use JavascriptExecutor to send the click directly on the element.
WebElement ele = driver.findElement(By.xpath("element_xpath"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", ele);
I assume, you've checked already that there is no any other component overlapping here (transparent advertisement-iframes or some other component of the DOM => seen quite often such things in input/textfield elements) and, when manually (slowly) stepping your code, it's working smoothly, then ajax calls might cause this behaviour.
To avoid thread.sleep, try sticking with EventFiringWebDriver and register a handle to it.
(Depending on your application's techstack you may work it for Angular, JQuery or wicket in the handler, thus requiring different implementations)
(Btw: This approach also got me rid of "StaleElementException" stuff lots of times)
see:
org.openqa.selenium.support.events.EventFiringWebDriver
org.openqa.selenium.support.events.WebDriverEventListener
driveme = new ChromeDriver();
driver = new EventFiringWebDriver(driveme);
ActivityCapture handle=new ActivityCapture();
driver.register(handle);
=> ActivityCapture implements WebDriverEventListener
e.g. javascriptExecutor to deal with Ajax calls in a wicket/dojo techstack
#Override
public void beforeClickOn(WebElement arg0, WebDriver event1) {
try {
System.out.println("After click "+arg0.toString());
//System.out.println("Start afterClickOn - timestamp: System.currentTimeMillis(): " + System.currentTimeMillis());
JavascriptExecutor executor = (JavascriptExecutor) event1;
StringBuffer javaScript = new StringBuffer();
javaScript.append("for (var c in Wicket.channelManager.channels) {");
javaScript.append(" if (Wicket.channelManager.channels[c].busy) {");
javaScript.append(" return true;");
javaScript.append(" }");
;
;
;
javaScript.append("}");
javaScript.append("return false;");
//Boolean result = (Boolean) executor.executeScript(javaScript.toString());
WebDriverWait wait = new WebDriverWait(event1, 20);
wait.until(new ExpectedCondition<Boolean>() {
public Boolean apply(WebDriver driver) {
return !(Boolean) executor.executeScript(javaScript.toString());
}
});
//System.out.println("End afterClickOn - timestamp: System.currentTimeMillis(): " + System.currentTimeMillis());
} catch (Exception ex) {
//ex.printStackTrace();
}
}
As #DebanjanB said, your button (or another element) could be temporarily covered by another element, but you can wait and click it even if you don't know which element is covering the button.
To do this, you can define your own ExpectedCondition with the click action:
public class SuccessfulClick implements ExpectedCondition<Boolean> {
private WebElement element;
public SuccessfulClick(WebElement element) { //WebElement element
this.element = element;
}
#Override
public Boolean apply(WebDriver driver) {
try {
element.click();
return true;
} catch (ElementClickInterceptedException | StaleElementReferenceException | NoSuchElementException e) {
return false;
}
}
}
and then use this:
WebDriverWait wait10 = new WebDriverWait(driver, 10);
wait10.until(elementToBeClickable(btn));
wait10.until(new SuccessfulClick(btn));
Try Thread.Sleep()
Implicit - Thread.Sleep()
So this isn’t actually a feature of Selenium WebDriver, it’s a common feature in most programming languages though.
But none of that matter.
Thread.Sleep() does exactly what you think it does, it’s sleeps the thread. So when your program runs, in the majority of your cases that program will be some automated checks, they are running on a thread.
So when we call Thread.Sleep we are instructing our program to do absolutely nothing for a period of time, just sleep.
It doesn’t matter what our application under test is up to, we don’t care, our checks are having a nap time!
Depressingly though, it’s fairly common to see a few instances of Thread.Sleep() in Selenium WebDriver GUI check frameworks.
What tends to happen is a script will be failing or failing sporadically, and someone runs it locally and realises there is a race, that sometimes WedDriver is losing. It could be that an application sometimes takes longer to load, perhaps when it has more data, so to fix it they tell WebDriver to take a nap, to ensure that the application is loaded before the check continues.
Thread.sleep(5000);
The value provided is in milliseconds, so this code would sleep the check for 5 seconds.
I was having this problem, because I had clicked into a menu option that expanded, changing the size of the scrollable area, and the position of the other items. So I just had my program click back on the next level up of the menu, then forward again, to the level of the menu I was trying to access. It put the menu back to the original positioning so this "click intercepted" error would no longer happen.
The error didn't happen every time I clicked an expandable menu, only when the expandable menu option was already all the way at the bottom of its scrollable area.

Explicit wait for two elements using OR operator in Selenium

I am trying to find either one of the 2 elements in selenium (java). If anyone is found then that should be clicked. following is not working;                                                            
WebDriverWait wait5 = new WebDriverWait(driver, 5);
wait5.until(ExpectedConditions.elementToBeClickable(By.xpath("//a[#data-period='R6M'] || //span[#title='FYTD']"))).click();
The xpath is invalid, or is a single |
wait5.until(ExpectedConditions.elementToBeClickable(By.xpath("//a[#data-period='R6M'] | //span[#title='FYTD']"))).click();
You can also use ExpectedConditions.or fo this
wait5.until(ExpectedConditions.or(
ExpectedConditions.elementToBeClickable(By.xpath("//a[#data-period='R6M']")),
ExpectedConditions.elementToBeClickable(By.xpath("//span[#title='FYTD']"))));
To get WebElement from one of two conditions you can build your own implementation
public ExpectedCondition<WebElement> customCondition(By... locators) {
#Override
public WebElement apply(WebDriver d) {
for (By locator in locators) {
return ExpectedConditions.elementToBeClickable(locator).apply(d);
}
}
}
WebElement element = wait4.until(customCondition(By.xpath("//a[#data-period='R6M']"), By.xpath("//span[#title='FYTD']")));
To induce WebDriverWait for either one of the 2 elements using Selenium java client you can use the following Locator Strategy:
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.or(
ExpectedConditions.elementToBeClickable(By.xpath("//a[#data-period='R6M']")),
ExpectedConditions.elementToBeClickable(By.xpath("//span[#title='FYTD']"))
));

How to wait for either of the two elements in the page using selenium xpath

How can I check if a non-input text element is clickable in Selenium? (Java)

I'm trying to check the clickability of a non-input text element (which can only be viewed but not edited). I have a test that where I want to assert that the view only text element (Ex: First Name) displayed on page can not be clicked.
I have tried using the isEnabled() method to check if the view only text element is enabled or not but the assertion is not happening correctly.
This is Bobcat Selenium code
Step definition code:
#Then("^I should verify that the First Name is not clickable$")
public void iShouldVerifyThatTheFirstNameIsNotClickable() {
assertEquals("Error: First Name is clickable", true,
fullName.verifyClick());
}
Page Object code:
public boolean verifyClick() {
if (firstName.isEnabled()) {
return true;
}
else {
return false;
}
}
Expected result: Since firstName is a view only element, the result of the verifyClick() method should be false so my #Then("^I should verify that the First Name is not clickable$") result should fail since the assertion is failing.
Actual result: #Then("^I should verify that the First Name is not clickable$") result is success.
There is a part of the selenium Java bindings that could be useful to you here. In ExpectedConditions you'll find a function called elementToBeClickable(). This returns a boolean that's false whenever the element is not clickable for any reason, and true when it can receive a click. So you just want to wait and see if that function returns true. Selenium handles that as well with the WebDriverWait class.
So you'll need to import both of those, and then you can do something like this:
//setting the timeout for our wait to be 20 seconds (you can use whatever you want)
WebDriverWait myWaitVar = new WebDriverWait(driver,20);
try {
WebElement myElement = myWaitVar.until(ExpectedConditions.elementToBeClickable(firstName)));
//assert test failed!
}
catch(timeoutException timeout) {
//whatever you want to do when the element is not clickable
}

Identifying which web form element is selected after pressing tab key via selenium web-driver java?

I am using the sendKeys(key,Keys.TAB) method to navigate through a form.
Actions action = new Actions(driver);
CharSequence key = null;
for(int i=0;i<42;i++)
{
action.sendKeys(key,Keys.TAB).build().perform();
}
At the end of every action(a tab key press) I want to know which form element is selected
I want to reach to the 42nd element of the form and cross check whether its the desired element and for that i need to retrieve some of its information.
I am new to selenium and I am not able to figure out a way to achieve this.
You can use WebDriver's TargetLocator class for this purpose.
WebElement currentElement = driver.switchTo().activeElement();
This will return you with current element it focussed currently. If no element is focussed it will return you the body element, which is the case when u launch your browser.
Internally it will be returning u the element returned by document.activeElement. So to verify u can always run as:
JavascriptExecutor js = (JavascriptExecutor) driver;
WebElement currentElement = (WebElement) js.executeScript("return document.activeElement");

Test if an element is present using Selenium WebDriver

Is there a way how to test if an element is present? Any findElement method would end in an exception, but that is not what I want, because it can be that an element is not present and that is okay. That is not a fail of the test, so an exception can not be the solution.
I've found this post: Selenium C# WebDriver: Wait until element is present.
But this is for C#, and I am not very good at it. What would the code be in Java? I tried it out in Eclipse, but I didn't get it right into Java code.
This is the code:
public static class WebDriverExtensions{
public static IWebElement FindElement(this IWebDriver driver, By by, int timeoutInSeconds){
if (timeoutInSeconds > 0){
var wait = new WebDriverWait(driver, TimeSpan.FromSeconds(timeoutInSeconds));
return wait.Until(drv => drv.FindElement(by));
}
return driver.FindElement(by);
}
}
Use findElements instead of findElement.
findElements will return an empty list if no matching elements are found instead of an exception.
To check that an element is present, you could try this
Boolean isPresent = driver.findElements(By.yourLocator).size() > 0
This will return true if at least one element is found and false if it does not exist.
The official documentation recommends this method:
findElement should not be used to look for non-present elements, use findElements(By) and assert zero length response instead.
Use a private method that simply looks for the element and determines if it is present like this:
private boolean existsElement(String id) {
try {
driver.findElement(By.id(id));
} catch (NoSuchElementException e) {
return false;
}
return true;
}
This would be quite easy and does the job.
You could even go further and take a By elementLocator as a parameter, eliminating problems if you want to find the element by something other than an id.
I found that this works for Java:
WebDriverWait waiter = new WebDriverWait(driver, 5000);
waiter.until( ExpectedConditions.presenceOfElementLocated(by) );
driver.FindElement(by);
public static WebElement FindElement(WebDriver driver, By by, int timeoutInSeconds)
{
WebDriverWait wait = new WebDriverWait(driver, timeoutInSeconds);
wait.until( ExpectedConditions.presenceOfElementLocated(by) ); //throws a timeout exception if element not present after waiting <timeoutInSeconds> seconds
return driver.findElement(by);
}
I had the same issue. For me, depending on a user's permission level, some links, buttons and other elements will not show on the page. Part of my suite was testing that the elements that should be missing, are missing. I spent hours trying to figure this out. I finally found the perfect solution.
It tells the browser to look for any and all elements based specified. If it results in 0, that means no elements based on the specification was found. Then I have the code execute an *if statement to let me know it was not found.
This is in C#, so translations would need to be done to Java. But it shouldn’t be too hard.
public void verifyPermission(string link)
{
IList<IWebElement> adminPermissions = driver.FindElements(By.CssSelector(link));
if (adminPermissions.Count == 0)
{
Console.WriteLine("User's permission properly hidden");
}
}
There's also another path you can take depending on what you need for your test.
The following snippet is checking to see if a very specific element exists on the page. Depending on the element's existence I have the test execute an if else.
If the element exists and is displayed on the page, I have console.write let me know and move on. If the element in question exists, I cannot execute the test I needed, which is the main reasoning behind needing to set this up.
If the element does not exist and is not displayed on the page, I have the else in the if else execute the test.
IList<IWebElement> deviceNotFound = driver.FindElements(By.CssSelector("CSS LINK GOES HERE"));
// If the element specified above results in more than 0 elements and is displayed on page execute the following, otherwise execute what’s in the else statement
if (deviceNotFound.Count > 0 && deviceNotFound[0].Displayed){
// Script to execute if element is found
} else {
// Test script goes here.
}
I know I'm a little late on the response to the OP. Hopefully this helps someone!
Try this:
Call this method and pass three arguments:
WebDriver variable. Assuming driver_variable as the driver.
The element which you are going to check. It should provide a from By method. Example: By.id("id")
Time limit in seconds.
Example: waitForElementPresent(driver, By.id("id"), 10);
public static WebElement waitForElementPresent(WebDriver driver, final By by, int timeOutInSeconds) {
WebElement element;
try{
driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS); // Nullify implicitlyWait()
WebDriverWait wait = new WebDriverWait(driver, timeOutInSeconds);
element = wait.until(ExpectedConditions.presenceOfElementLocated(by));
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); // Reset implicitlyWait
return element; // Return the element
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
This works for me:
if(!driver.findElements(By.xpath("//*[#id='submit']")).isEmpty()){
// Then click on the submit button
}
else{
// Do something else as submit button is not there
}
You can make the code run faster by shorting the Selenium timeout before your try-catch statement.
I use the following code to check if an element is present.
protected boolean isElementPresent(By selector) {
selenium.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);
logger.debug("Is element present"+selector);
boolean returnVal = true;
try{
selenium.findElement(selector);
} catch (NoSuchElementException e) {
returnVal = false;
} finally {
selenium.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
}
return returnVal;
}
Write the following function/methods using Java:
protected boolean isElementPresent(By by){
try{
driver.findElement(by);
return true;
}
catch(NoSuchElementException e){
return false;
}
}
Call the method with the appropriate parameter during the assertion.
If you are using rspec-Webdriver in Ruby, you can use this script, assuming that an element should really not be present, and it is a passed test.
First, write this method first from your class RB file:
class Test
def element_present?
begin
browser.find_element(:name, "this_element_id".displayed?
rescue Selenium::WebDriver::Error::NoSuchElementError
puts "this element should not be present"
end
end
Then, in your spec file, call that method.
before(:all) do
#Test= Test.new(#browser)
end
#Test.element_present?.should == nil
If your element is not present, your spec will pass, but if the element is present, it will throw an error, and the test failed.
Personally, I always go for a mixture of the above answers and create a reusable static utility method that uses the size() > 0 suggestion:
public Class Utility {
...
public static boolean isElementExist(WebDriver driver, By by) {
return driver.findElements(by).size() > 0;
...
}
This is neat, reusable, maintainable, etc.—all that good stuff ;-)
public boolean isElementDisplayed() {
return !driver.findElements(By.xpath("...")).isEmpty();
}
This should do it:
try {
driver.findElement(By.id(id));
} catch (NoSuchElementException e) {
//do what you need here if you were expecting
//the element wouldn't exist
}
I would use something like (with Scala [the code in old "good" Java 8 may be similar to this]):
object SeleniumFacade {
def getElement(bySelector: By, maybeParent: Option[WebElement] = None, withIndex: Int = 0)(implicit driver: RemoteWebDriver): Option[WebElement] = {
val elements = maybeParent match {
case Some(parent) => parent.findElements(bySelector).asScala
case None => driver.findElements(bySelector).asScala
}
if (elements.nonEmpty) {
Try { Some(elements(withIndex)) } getOrElse None
} else None
}
...
}
so then,
val maybeHeaderLink = SeleniumFacade getElement(By.xpath(".//a"), Some(someParentElement))
The simplest way I found in Java was:
List<WebElement> linkSearch= driver.findElements(By.id("linkTag"));
int checkLink = linkSearch.size();
if(checkLink!=0) {
// Do something you want
}
To find if a particular Element is present or not, we have to use the findElements() method instead of findElement()...
int i = driver.findElements(By.xpath(".......")).size();
if(i=0)
System.out.println("Element is not present");
else
System.out.println("Element is present");
This is worked for me...
You can try implicit wait:
WebDriver driver = new FirefoxDriver();
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10));
driver.Url = "http://somedomain/url_that_delays_loading";
IWebElement myDynamicElement = driver.FindElement(By.Id("someDynamicElement"));
Or you can try explicit wait one:
IWebDriver driver = new FirefoxDriver();
driver.Url = "http://somedomain/url_that_delays_loading";
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
IWebElement myDynamicElement = wait.Until<IWebElement>((d) =>
{
return d.FindElement(By.Id("someDynamicElement"));
});
Explicit will check if the element is present before some action. Implicit wait could be called in every place in the code. For example, after some Ajax actions.
More you can find at SeleniumHQ page.
I am giving my snippet of code. So, the below method checks if a random web element 'Create New Application' button exists on a page or not. Note that I have used the wait period as 0 seconds.
public boolean isCreateNewApplicationButtonVisible(){
WebDriverWait zeroWait = new WebDriverWait(driver, 0);
ExpectedCondition<WebElement> c = ExpectedConditions.presenceOfElementLocated(By.xpath("//input[#value='Create New Application']"));
try {
zeroWait.until(c);
logger.debug("Create New Application button is visible");
return true;
} catch (TimeoutException e) {
logger.debug("Create New Application button is not visible");
return false;
}
}
In 2022 this can now be done without an annoying delay, or affecting your current implicit wait value.
First bump your Selenium driver to latest (currently 4.1.2).
Then you can use getImplicitWaitTimeout then set timeout to 0 to avoid a wait then restore your previous implicit wait value whatever it was:
Duration implicitWait = driver.manage().timeouts().getImplicitWaitTimeout();
driver.manage().timeouts().implicitlyWait(Duration.ofMillis(0));
final List<WebElement> signOut = driver.findElements(By.linkText("Sign Out"));
driver.manage().timeouts().implicitlyWait(implicitWait); // Restore implicit wait to previous value
if (!signOut.isEmpty()) {
....
}
Try the below code using the isDispplayed() method to verify if the element is present or not:
WebElement element = driver.findElements(By.xpath(""));
element.isDispplayed();
There could be multiple reasons due to which you might observe exceptions while locating a WebElement using Selenium driver.
I would suggest you to apply the below suggestions for different scenarios:
Scenario 1: You just want to find out if a certain WebElement is present on the screen or not. For example, the Save button icon will only appear until the form is fully filled and you may want to check if Save button is present or not in your test.
Use the below code -
public Boolean isElementLoaded(By locator){
return !getWebElements(this.driver.findElements(locator), locator).isEmpty();
}
Scenario 2: You want to wait before a WebElement becomes visible in the UI
public List<WebElement> waitForElementsToAppear(By locator) {
return wait.until(visibilityOfAllElementsLocatedBy(by));
}
Scenario 3: Your test is flaky because the WebElement becomes stale sometimes and gets detached from the DOM.
protected final List<Class<? extends WebDriverException>> exceptionList =
List.of(NoSuchWindowException.class,
NoSuchFrameException.class,
NoAlertPresentException.class,
InvalidSelectorException.class,
ElementNotVisibleException.class,
ElementNotSelectableException.class,
TimeoutException.class,
NoSuchSessionException.class,
StaleElementReferenceException.class);
public WebElement reactivateWebElement(By by, WebElement element){
try {
wait.ignoreAll(exceptionList)
.until(refreshed(visibilityOf(element)));
logger.info(("Element is available.").concat(BLANK).concat(element.toString()));
} catch (WebDriverException exception) {
logger.warn(exception.getMessage());
} return this.driver.findElement(by);
}
