IEDriver implementation fails the test - selenium-webdriver

I am using Webdriver(without IEDriver implementation) 2.23 API on windows7 machine with JDK7 and JRE7. The test scripts are working fine as expected but when i introduced IEDriver the script fails in a page with cannot click on element error message as that corresponding element is not visible. i have double checked with my application for the locator. The same can be clicked with out IEDriver implementation. I have tried by simulating all the click types including context click by Action class. No use. All click types returns the same result. Any help ?

Finally, i was manage to click the above said Element with the help of following code.
WebElement we = driver.findElement(By.name("Complete"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", we); // common for all we
The real source is here. This may helpful for someone.

As you say that the element is actually visible and the error's log says it is not, I think that the problem might be due to Internet Explorer's slowness. You could use this method for a quick test:
boolean isElementDisplayed(final WebDriver driver, final WebElement element, final int timeoutInSeconds) {
try {
ExpectedCondition condition = new ExpectedCondition<Boolean>() {
#Override
public Boolean apply(final WebDriver webDriver) {
return element.isDisplayed();
}
};
Wait w = new WebDriverWait(driver, timeoutInSeconds);
w.until(condition);
} catch (Exception ex) {
//if you get here, it's because the element is not displayed after timeoutInSeconds
return false;
}
return true;
}
Use it like this:
WebElement we = driver.findElement(By.name("Complete"));
if (isElementDisplayed(driver, we, 30)) {
we.click();
}
This will make the driver wait (30 sec max.) till the element we becomes visible and then the driver clicks on it.
If it works, then my supposition is right and you could change the method for:
void clickOn(final WebDriver driver, final WebElement element, final int timeoutInSeconds) {
try {
ExpectedCondition condition = new ExpectedCondition<Boolean>() {
#Override
public Boolean apply(final WebDriver webDriver) {
element.click();
return true;
}
};
Wait w = new WebDriverWait(driver, timeoutInSeconds);
w.until(condition);
} catch (Exception ex) {
//probably some kind of exception thrown here
}
return;
}
and use it instead of we.click(), like:
WebElement we = driver.findElement(By.name("Complete"));
clickOn(driver, we, 30);
The code above is an approximation to let you check your issue in a quick and clear way and, if you end up using it, you should adapt it to your structure of code. This kind of utility code should never appear in your tests. Your test code should be clean and the same for all the environments (browsers, version, SOs, etc.). Keep the workarounds separately, e.g. some kind of util package.
Also, the method's signature is 'overweight'. Restructuring your util code, you should be able to write in your tests just this: clickOn(element).
Hope it helps ;)
UPDATE Actually, with these components I had never run into a similar problem:
selenium-server-standalone version 2.32.0
IEDriverServer_x64_2.30.1.exe

Is there a way to do an "if I see, then…" with webdriver acceptance testing?

I'm using webdriver for acceptance testing. https://codeception.com/docs/03-AcceptanceTests#WebDriver
I'm running into a thing where depending on if new features are launched, a popup will sometimes be there to notify the user of the new features. So that popup may or may not be there depending on where we are in the release cycle. Is there a way to say: "If I see , click Close" ?
You didn't say which programming language you are using, but the following in Groovy (Java) checks for an alert/modal popup. You can dismiss it in the method or use the return value in an if statement.
You should be able to adapt it for your language.
def isAlertPresent(driver){
boolean foundAlert = false
WebDriverWait wait = new WebDriverWait(driver, 10) //time-out secs
try {
wait.until(ExpectedConditions.alertIsPresent())
foundAlert = true
} catch (TimeoutException e) {
foundAlert = false
}
return foundAlert
}
Did you checked out if Cucumber.io and Gherkin syntax works for you?
With Gherkin you’ll be able to do everything you want.

Element ... is not clickable at point (35, 37) [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.

I am getting null pointer exception for webelement defined under #FindBy annotation in page factory model

I'm new in Selenium learning. I'm getting null pointer exception when I try to use web element - Milestone_Tile_Text.click; in my code but it works fine when I use
LoginTestScript.fd.findElement(By.linkText("Milestone")).click();
Please see below code I have used PageFactory.initElements as well but not sure how to solve this error.
public class MilestoneTileModel
{
GenerateTestData objtestdata = new GenerateTestData() ;
public MilestoneTileModel() //constructor
{
PageFactory.initElements(LoginTestScript.fd, this);
}
#FindBy(xpath="//a[text()='Milestone']")
WebElement Milestone_Tile_Text;
public void Milestone_Tile_Click()
{
Milestone_Tile_Text.click();
LoginTestScript.fd.findElement(By.linkText("Milestone")).click();
LoginTestScript.fd.findElement(By.xpath("//*#id='CPH_btnAddNewMilestoneTop']")).click();
}
}
Timing issues might occur more often when you use an init method.
The timing issue is when you init an element the driver immediately try to find the elements, on failure you will get no warning but the elements will refer null.
The above can occur for example because the page was not fully rendered or the driver see an older version of the page.
A fix can be to define the elements as a property and on the get of the property use the driver to get the element from the page
Please note that selenium does not promise the driver sees the latest version of the page so even this might break and on some situations a retry will work.
First problem what I see: You didn't set LoginTestScript
Following documentation at first you need to set PageObject variable:
GoogleSearchPage page = PageFactory.initElements(driver, GoogleSearchPage.class);
The best way to rich that point is separate Page Object Model and scenario scipt
You fist file POM should contain:
LoginTestPOM
public class LoginTestPOM {
#FindBy(xpath="//a[text()='Milestone']")
WebElement MilestoneTileText;
public void clickMilestoneTitleText(){
MilestoneTitleText.click();
}
}
TestScript
import LoginTestPOM
public class TestLogin {
public static void main(String[] args) {
// Create a new instance of a driver
WebDriver driver = new HtmlUnitDriver();
// Navigate to the right place
driver.get("http://www.loginPage.com/");
// Create a new instance of the login page class
// and initialise any WebElement fields in it.
LoginTestPOM page = PageFactory.initElements(driver, LoginTestPOM.class);
// And now do the page action.
page.clickMilestoneTitleText();
}
}
This is basis of Page Object Pattern.
NOTE: I'm writing that code only in browser so it could contain some mistakes.
LINK: https://github.com/SeleniumHQ/selenium/wiki/PageFactory
The "ugly" solution without page object pattern is:
UglyTestScript
public class UglyTestLogin {
public static void main(String[] args) {
// Create a new instance of a driver
WebDriver driver = new HtmlUnitDriver();
// Navigate to the right place
driver.get("http://www.loginPage.com/");
// DON'T create a new instance of the login page class
// and DON'T initialise any WebElement fields in it.
// And do the page action.
driver.findElement(By.xpath("//a[text()='Milestone']").click()
}
}

Are there situations where an ExplictWait is not working?

I know about the three different types of waiting you can use in Selenium. I know why Thread.Sleep and ImplicitWait are never a good choice. So I'm always using ExplicitWaits, for instance to wait till a button is clickable. However, from time to time one or two tests in a collection of hundred tests fails because the Explictwait seems to fail.
I read the very interesting article: https://bocoup.com/weblog/a-day-at-the-races
about the reason why tests can fail from time to time and Explicit wait as the solution for this intermittent failures. This made me even more convinced about using ExplictWaits.
So I wonder is there anybody who knows situations were an Explicitwait is not doing the right job.
This is my C# code for waiting till a Webelement is clickable:
public static Boolean waitElementToBeClickable(IWebDriver driver, int seconds, IWebElement webelement)
{
Boolean clickable = true;
try
{
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(seconds));
wait.Until(ExpectedConditions.ElementToBeClickable(webelement));
}
catch
{
clickable = false;
}
return clickable;
}

Alert doesn't close using Selenium WebDriver with Google Chrome.

I have the following Selenium script for opening alert on rediff.com:
public class TestC {
public static void main(String[] args) throws InterruptedException, Exception {
System.setProperty("webdriver.chrome.driver", "driver/chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://www.rediff.com/");
driver.findElement(By.xpath("//*[#id='signin_info']/a[1]")).click();
driver.findElement(By.id("btn_login")).click();
Thread.sleep(5000);
Alert alert=driver.switchTo().alert();
alert.accept();
}
}
This very same script is working fine in Firefox and IE9, however using Google Chrome after opening the alert, rest of the code is not working. The main thing is that does not shows any exception, error or anything.
Please provide any solution as soon as possible.
Thanks a lot!
Note: If we need to change any setting of browser or any thing please let me know.
Selenium version:Selenium(2) Webdriver
OS:Windows 7
Browser:Chrome
Browser version:26.0.1410.64 m
I'm pretty sure your problem is a very common one, that's why i never advise using Thread.sleep(), since it does not guarantee the code will run only when the Alert shows up, also it may add up time to your tests even when the alert is shown.
The code below should wait only until some alert is display on the page, and i'd advise you using this one Firefox and IE9 aswell.
public class TestC {
public static void main(String[] args) throws InterruptedException, Exception {
System.setProperty("webdriver.chrome.driver", "driver/chromedriver.exe");
WebDriver driver = new ChromeDriver();
WebDriverWait wait = new WebDriverWait(driver, 5);
driver.get("http://www.rediff.com/");
driver.findElement(By.xpath("//*[#id='signin_info']/a[1]")).click();
driver.findElement(By.id("btn_login")).click();
wait.until(ExpectedConditions.alertIsPresent());
Alert alert = driver.switchTo().alert();
alert.accept();
}
}
Mostly all that is done here, is changing Thread.sleep(), for a condition that actually will only move forward on the code as soon a alert() is present in the page. As soon as someone does, it wil switch to it and accept.
You can find the Javadoc for the whole ExpectedConditions class here.
Unfortunately AlertIsPresent doesn't exist in C# API
http://selenium.googlecode.com/git/docs/api/dotnet/index.html
You can use something like this:
private static bool TryToAcceptAlert(this IWebDriver driver)
{
try
{
var alert = driver.SwitchTo().Alert();
alert.Accept();
return true;
}
catch (Exception)
{
return false;
}
}
public static void AcceptAlert(this IWebDriver driver, int timeOutInSeconds = ElementTimeout)
{
new WebDriverWait(driver, TimeSpan.FromSeconds(timeOutInSeconds)).Until(
delegate { return driver.TryToAcceptAlert(); }
);
}
