I use Selenium and PHPUnit. In my testcases, I use
PHPUnit_Extensions_SeleniumTestCase::waitForElementPresent($xpath);
to wait for some time until element specified by $xpath becomes present. Is there any way to change the maximum time of waiting?
waitForElementPresent() takes two arguments. The first one is the locator and the other is Timeout in miliseconds.
Example :
waitForElementPresent("Your xpath","80000").
This will wait for the given xpath for 80 seconds.

For example, HTML:
<input type="hidden" name="ie" value="utf-8">
this element don't have child element, when I use code:
List<WebElement> childElements = ele.findElements(By.xpath("./*"));
the program uses a very long time (about 30s) return a result. And the result size is right which is zero.
So how can I resolve this problem? Thanks.
As per the documentation findElements() method is affected by the implicit wait duration in force at the time of execution. When implicitly waiting, findElements() method will return as soon as there are more than 0 items in the found collection, or will return an empty list if the timeout is reached.
Possibly you have set implicitlyWait() somewhere before this block of code and configured as 30 seconds. Hence the TimeOut occurs at 30 seconds.
I need to change timeout for waiting particular webElements. For all of others default is pretty fine. Default timeout could be changed in settings:
timeout.wait.element=10
How to change timeout only for given elements?
For setting specific timeout on element you can use
textField.setWaitTimeout(10);
textField.input("TEXT");
But if you also has some waiting criteria and want to do something after it becomes true you can use
String text = textField.wait(w -> w.getText(), t -> t.equals("test"), 10);
or textField.wait(w -> w.getText().equals("test"), 10); if you just want to wait something
For setting specific implicit timeout on element you can use #WaitTimeout(sec)
#WaitTimeout(sec) — set sec seconds implicit wait for the element
or if you just want to wait until element is present in DOM:
someWebElement.waitFor(10).displayed();
I'm trying to click a specific link in the web page with specific text.
However, if the link is not present, it takes 1 minute before it prints out element is not found. How do I reduce this time for faster execution?
try{
if (!driver.findElements(By.xpath("//a[text()='specifictext']/#href")).isEmpty())
{
By loadMoreComment=By.linkText("specifictext");
driver.findElement(loadMoreComment).click();
}
}
catch (NoSuchElementException e)
{
logger.warn("Specific text not found");
}
That would only happen because of implicit waits. Look at below definition
Implicit Waits
An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance.
So you should lower that implicit wait if you want an early failure
driver.manage().timeouts().implicitlyWait(2, TimeUnit.SECONDS);
The above call before your code, will ensure the failure happens within 2 seconds
Use Implicit wait to reduce tag waiting time.
Implicit waits are used to provide a waiting time (say 30 seconds)
between each consecutive test steps across the entire test script or
program. Next step only executed when the 30 Seconds (or whatever time
is given is elapsed) after execution of previous step.
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
Implicit Wait : If wait is set, it will wait for specified amount of time for each findElement/findElements call. It will throw an exception if action is not complete.
Assume we set implicit wait to 10 secs. My question is will selenium move on to next step if findElement action is complete before 10 secs?
Yes. Setting implicit wait causes the driver object to wait for the set time if the element it is looking for is not found immediately. The driver object keeps polling the DOM every 500 milliseconds until it finds the element or the time-out expires.
This is the explanation from official Selenium documentation page:
An implicit wait is to tell WebDriver to poll the DOM for a certain
amount of time when trying to find an element or elements if they are
not immediately available. The default setting is 0. Once set, the
implicit wait is set for the life of the WebDriver object instance.
So, to answer your question in short, yes it continues with executing next steps as soon as it finds the element(s) it is looking for. You may also understand that to be the case from a simple experiment like #sircapsalot has shown in his answer.
Answer:
Yes. It will continue with the next step if it finds the element before the implicit timeout is hit.
Proof of concept:
#Test
public void test29800926() {
driver.get("http://ddavison.io/tests/getting-started-with-selenium.htm");
driver.manage().timeouts().implicitlyWait(30000, TimeUnit.MILLISECONDS);
System.out.println(driver.findElement(By.id("click")).getText());
}
Instead of waiting the total of 30 seconds that I set the implicit wait to (30000ms / 1000 = 30sec), it found it immediately and continued to print the text of the element.
I have been using Selenium WebDriver. I want to wait until the element is present on the webpage, for which i am using:
WebDriverWait wait = new WebDriverWait(driver, Long.parseLong(timeout));
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(locator)));
but my test get stucks in the second line if the element I am looking for, is not present and even beyond the timeout. Pls Help. Thanks.
Maybe:
- the element is present, so no exception is thrown
- then gets stuck because you are not doing anything else afterwards
Try printing smt after the until call. My guess is it will get printed.
Otherwise maybe it's the timeout:
It must be in seconds, not milli seconds.
http://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/support/ui/WebDriverWait.html#WebDriverWait(org.openqa.selenium.WebDriver, long)
I got it worked. I changed the timeout from 60000 to 60 since it takes the second argument as seconds and not millisecs.
