Unable to locate elements via Selenium if ran via Bitbucket pipeline - java

I am currently working on integration tests in Selenium. I have some testset, which tests presence of webelements and their behaviour. Everything works perfectly if I run these tests on my local machine. As a WebDriver I use ChromeDriver.
But some of these tests fail, if I run them in pipeline on bitbucket. It fails because it was not able to locate element, the worst thing is that in pipeline it behaves sort of undeterministic - that it sometimes locate this element and sometimes it doesn't (no code changed between run in which element was found and in which element was not found, Website tested was not changed either between runs.)
Expected condition failed: waiting for presence of element located by... (tried for 300 second(s) with 500 milliseconds interval)
On my local machine, which is not really fast one, 30s timeout is perfectly enough for me. And tests always pass on my local machine. Is it that pipeline on bitbucket runs extremely slowly or do I miss something?
webDriver.get(getTerminalUrl());
WebDriverWait wait = new WebDriverWait(webDriver, 60);
wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("//*[text()='Sign In']")));
WebElement login = webDriver.findElement(By.xpath("//*[text()='Sign In']"));
login.click();
I use this kind of pattern in all my tests.

Try doing like this:
webDriver.get(getTerminalUrl());
WebDriverWait wait = new WebDriverWait(webDriver, 60);
boolean elementPresent = driver.findElements(By.xpath("//*[text()='Sign In']")).size() > 0;
if(elementPresent){
Thread.sleep(3000);
WebElement login = webDriver.findElement(By.xpath("//*[text()='Sign In']"));
Thread.sleep(3000);
login.click();
}

Does Selenium WebElement.Click() wait until the next page is loaded?

I tell Selenium to wait until it sees an element - Selenium sees it
I tell Selenium to click on this element, it is a button to link to a new page - Selenium click on it.
The problem is that after clicking it, Selenium will then wait until the next page is fully loaded (the page sometimes loads in a second, or waits for ages, I think it's a problem with Zen Desk Live Chat on that page).
When it is fully loaded it will then throw an error and say that the element it clicked on cannot be seen (naturally it can't because it is now on a new page)
I have tried changing the wait time with
driver.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);
however this doesn't help.
I have also tried
wait.until(ExpectedConditions.visibilityOfElementLocated(
By.xpath(element)));
However this has the same problem.
Below is the code I am currently using.
try {
wait.until(ExpectedConditions.visibilityOfElementLocated(
By.xpath(element)));
WebElement we = driver.findElement(By.xpath(element));
we.click();
System.out.println("Clicked: " + element);
}catch (Exception e){
System.out.println(e.getMessage());
}
I expect that once the element has been clicked on, that Selenium just carries on without caring if the next page has loaded up or not.
However what happens is when the 2nd page loads up, sometimes the page gets stuck "waiting for widget-mediator.zopim.com" and Selenium will not progress past the click() line until the the WebDriverWait time has expired (60 seconds)
After the 60 seconds has expired I see this error in the Console Output:
[1561374309.111][SEVERE]: Timed out receiving message from renderer: 60.000
[1561374309.112][SEVERE]: Timed out receiving message from renderer: -0.002
Is something else happening here? Or does Click() wait until the page has loaded, if that click takes it to a new page? If it does is there a way to tell it to stop waiting? I have other code to check if the page has loaded or not, but I don't need Click() to do this.
Thanks in advance.
Selenium’s (or more correctly, WebDriver’s) behavior on click is governed by the W3C WebDriver Specification. In that document, the full algorithm is defined for what happens when an element click is requested. In general, if the click will navigate to a new page, the driver will wait for that new page to be “loaded” (scare quotes intentional) according to the page load strategy until the page load timeout.
The page load strategy defaults to “normal”, or waiting for the document’s readyState to be complete. If you set it to “none” in the capabilities requested during driver instantiation, the driver will not wait at all. Choosing that route would mean you would need to handle all synchronization for pages being loaded. Note there is a third page load strategy, “eager”, but at the time of this writing, not all WebDriver implementations (most notably chromedriver) support it.
You can adjust the page load timeout at runtime in your Selenium code. One approach might be to lower the timeout to a relatively low value for the duration of clicking on this particular element, then restoring it to its prior value afterward. The drawback here is that you will have to catch the timeout exception that is thrown when the page load times out before continuing.

ExplicitWait taking more time if an element removed from DOM

I'm automating this website But facing the issue with ExplicitWaitConditions to manage the time.
Scenario is When i click on Login link or Submit button after send username, It shows a loader during the process, once process has completed the loader get removed from DOM.
I have used condition for invisibilityOfElementLocated like below
new WebDriverWait(driver, 60).until(ExpectedConditions.invisibilityOfElementLocated(By.id("loading-bar")));
But this can't predict correct time it taking more time (not exectly 60 sec but around 15-20 or may be 30 sec.) then allow to execute next command.
The same line i have to put before 4 commands to do complete login process. So it seems to consumed around 90 second to do login.
If i do not use Explicitwait or remove Impliciwait wait then script failed all time as loader get click instead of some other element.
The code i tried so far :
WebDriver driver = new FirefoxDriver();
System.out.println("Browser Opened");
driver.manage().window().maximize();
driver.get("https://www.rcontacts.in");
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
System.out.println("URL Opened");
new WebDriverWait(driver, 60).until(ExpectedConditions.invisibilityOfElementLocated(By.id("loading-bar")));
driver.findElement(By.cssSelector(".ng-scope>a span[translate='login.register']")).click();
System.out.println("Register Link Clicked");
driver.findElement(By.name("userId")).sendKeys("9422307801");
new WebDriverWait(driver, 60).until(ExpectedConditions.invisibilityOfElementLocated(By.id("loading-bar")));
driver.findElement(By.xpath("//button[#type='submit']")).click();
System.out.println("Mobile number entered");
new WebDriverWait(driver, 60).until(ExpectedConditions.invisibilityOfElementLocated(By.id("loading-bar")));
Is there any solution that as soon as loader get removed it start performing actions ?
OR is there any way that I can wait until loader element get removed from DOM. Once removed then i can continue the further actions ?.
According to the docs,
WARNING: Do not mix implicit and explicit waits. Doing so can cause unpredictable wait times.
That's likely the cause of your issues. It's recommended to not use implicit waits. I would remove them and then add explicit waits as needed and see how that goes.
I took your code and rewrote it (below) and it's working every time for me.
String url = "https://www.rcontacts.in";
driver.navigate().to(url);
waitForLoader();
driver.findElement(By.cssSelector("span[translate='login.register']")).click();
waitForLoader();
driver.findElement(By.cssSelector("input[name='userId']")).sendKeys("9422307801");
driver.findElement(By.cssSelector("button[translate='common.btns.next']")).click();
The issue I was having at times was that many times the script was jumping ahead. I added code to waitForLoader() to wait for the loader to appear (be visible) and then disappear (be invisible). Once I did that, it worked 100% of the time.
public static void waitForLoader()
{
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.id("loading-bar")));
wait.until(ExpectedConditions.invisibilityOfElementLocated(By.id("loading-bar")));
}
First and foremost, you have induced implicitlyWait() as follows:
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
As well as WebDriverWait() as follows:
new WebDriverWait(driver, 60).until(ExpectedConditions.invisibilityOfElementLocated(By.id("loading-bar")));
As per the documentation of Explicit and Implicit Waits it is clearly mentioned that:
Do not mix implicit and explicit waits. Doing so can cause unpredictable wait times. For example setting an implicit wait of 10 seconds and an explicit wait of 15 seconds, could cause a timeout to occur after 20 seconds.
Again, it seems changing the ExpectedConditions clause from invisibilityOfElementLocated(By.id("loading-bar") to elementToBeClickable(By.xpath("//span[contains(text(),'Register')]") gives me a success rate of 80%. Here is the effective code block on my Windows 8 box:
System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.rcontacts.in");
System.out.println("URL Opened");
WebDriverWait wait = new WebDriverWait (driver, 15);
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("//span[contains(text(),'Register')]")));
driver.findElement(By.xpath("//span[contains(text(),'Register')]")).click();
System.out.println("Register Link clicked");
Note: Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully to ensure that no dangling instance of geckodriver is present (through Task Manager) while you initiate the execution.

How to get PhantomJSDriver to work in selenium?

I am trying to use the PhantomJSDriver. The code below works with
FirefoxDriver but will not work with PhantomJSDriver. The error is:
[ERROR - 2016-02-12T16:02:47.717Z] WebElementLocator -
_handleLocateCommand - Element(s) NOT Found: GAVE UP. Search Stop Time: 1455292967683 org.openqa.selenium.NoSuchElementException: Error
Message => 'Unable to find element with id 'email''
Is there any clear guides on how to do this in Java, or can anyone get this working to login? I'm struggling to find some clarity on this topic.
I'm assuming the error is something to do with the browser being headless which therefore messes up with the paths but I have seen others using similar code and it works for them.
WebDriver driver = new PhantomJSDriver();
try {
System.out.println("Logging in to Facebook...");
driver.get("https://www.facebook.com/login");
System.out.println(driver.getTitle());
driver.findElement(By.id("email")).sendKeys("USERNAME");
driver.findElement(By.id("pass")).sendKeys("PASS");
driver.findElement(By.id("loginbutton")).click();
}
catch (Exception e) {
e.printStackTrace();
}
There's hundreds of similar questions to this one, e.g. this one. It's an issue that applies more or less equally to all browsers, and is a major cause of test instability.
Basically you're asking the Driver to find id="email" almost immediately (within milliseconds) after the page has been requested, and almost certainly before it has finished loading or that web element has been created in the DOM.
The solution is to wait until the element is ready before trying to send keys to it. See these examples. E.g.
System.out.println(driver.getTitle());
WebDriverWait wait = new WebDriverWait(driver, 10); // 10 secs max wait
wait.until(ExpectedConditions.presenceOfElementLocated( By.id("email") ));
driver.findElement(By.id("email")).sendKeys("USERNAME");
Once you know the DOM is loaded, there's no need to wait for the other elements.

Appium's implicitlyWait does not work

I am using Appium to automate an iOS app but met a problem, is there anyone meet the same problem before?
Appium's implicitlyWait API seems to not work. I am using Java and JUnit to run the test, here is the line of code:
driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS);
I have checked the debug info in the appium console, it looks correctly:
info: [debug] Set iOS implicit wait to 50000ms
My Environment:
Latest Appium 1.2.1, Java client library 1.6.1, Selenium Java language binding 2.42.2 and sample app 'UICatalog'provided by Sauce Lab.
Thanks in advance for the reply.
The code you have posted manages the timeout to wait for a maximum of 50 seconds. It doesn't make the driver wait 50 seconds. You can use the wait like:
driver.wait(); //this will wait a max of 50 seconds cuz you said so
If you ask me the proper way you would want to use waiting on Webdriver is:
WebDriverWait wait;
wait = new WebDriverWait(driver, 60);
wait.until(ExpectedConditions.elementToBeClickable(By.id("blabla"));
The code above checks if blabla is clickable until that condition is proved or 60 seconds(stated above) passes the driver waits.
In Appium it is possible to set implicit way in this way:
Java code:
AppiumFieldDecorator decorator = new AppiumFieldDecorator(driver);
decorator.resetImplicitlyWaitTimeOut(50, TimeUnit.SECONDS);
PageFactory.initElements(decorator, this /* refers to current page object class*/);
Such timeout will work for the whole time.
It is not possible (at least I don't know) to change it.
As when web drivers are used you can do this with:
driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS);
// some actions for which you don't want to wait implicitly
driver.manage().timeouts().implicitlyWait(50, TimeUnit.SECONDS);
Try this:
public static void WaitForElementPresent1(String locator, int timeout)
{
WebDriverWait wait = new WebDriverWait(driver, timeout);
try{
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(locator)));
} catch (Exception e){
e.printStackTrace();
}
}
If you are using PageFactory model, you can specify the implicit wait with initElements() method as given below -
PageFactory.initElements(new AppiumFieldDecorator(driver, 10, TimeUnit.SECONDS), this);
I have tried this with Appium 1.6 and it works fine.
The new way of setting the implicit time out is using the code
AppiumFieldDecorator decorator = new AppiumFieldDecorator(mobDriver);
decorator.DEFAULT_IMPLICITLY_WAIT_TIMEOUT = longValue;
decorator.DEFAULT_TIMEUNIT = TimeUnit.TimeUnit ;
Hope this helps

Setting timeout with testNG and Selenium in Java

I've got a problem with testing in Java. I'm using TestNG & Selenium. I wanted to run a method with annotaion #Test on long period of time, but it stopped in about 5000 seconds. I've tried to set attribute Timeout, but it didn't work for me. How can I control execution time of test method?
Sometimes I've noticed that my test method before stop after around 5000 seconds threw exception "org.openqa.selenium.remote.SessionNotFoundException: Session ID is null".
Use WebDriver Wait and Wait Until Expected Conditions before Performing Any Action on Any Element, So that testcases Never Fails due to Timing Issues
WebDriverWait wait = new WebDriverWait(driver, 80);// Maximum TimeOut
PageUtil.refreshObject(driver, By.linkText("Link_yu_want_to_click"));
wait.until(ExpectedConditions.elementToBeClickable(By.linkText("Link_yu_want_to_click")));
