what's the equivalent of waitForPageLoad in webdriver

[shen xieyin]

Hi,

I am now doing a pilot work to migrate our test code from selenium1 to
selenium2, when I use findElement(By).click to find the target
element, which cause a page to reload or to load to a new page, so
what method can I call to wait for page load to be finished, just like
waitForPageLoad in Selenium interface originally?


Thanks,
-Jovi

You dont need to use any wait for page load method. Driver instance you have created should take care of the page. Whenever a page is loaded completely then only it will perform further actions.,, However if you want to use any wait for page to load then you can design one with Thread.sleep(1000) method using a for loop and a break. However driver instance created in Webdriver takes care of page loading automatically.

Hope this helps.

Just to clarify:  WebDriver.get() will block until the page has loaded - this corresponds to the firing of the onload event.  To make sure the elements you want to interact with are present on the page, you should use one of the wait mechanisms.  There are two possibilities:

1. Use implicit waits. Here the driver will wait up until the designated timeout until the element is found.  Be sure to read the javadoc for the caveats.  Usage:

  driver.get("http://www.google.com");

  driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

  WebElement element = driver.findElement(By.name("q"));

  driver.manage().timeouts().implicitlyWait(0, TimeUnit.SECONDS);

  // continue with test...

2. Use the org.openqa.selenium.support.ui.WebDriverWait class.  This will poll until the expected condition is true, returning that condition's result (if it's looking for an element).  This is much more flexible than implicit waits, as you can define any custom behavior.  Usage:

Function<WebDriver, WebElement> presenceOfElementLocated(final By locator) {

  return new Function<WebDriver, WebElement>() {

    public WebElement apply(WebDriver driver) {

      return driver.findElement(locator);

    }

  };

}

// ...

driver.get("http://www.google.com");

WebDriverWait wait = new WebDriverWait(driver, /*seconds=*/3);

WebElement element =

    wait.until(presenceOfElementLocated(By.name("q"));

Thanks Jason

Just wondering if webdriverwait class is available with .net libraries of webdriver.. as i am using C# for doing automation.

However methods you have suggested looks interesting Thanks a lot!!!

thanks, but further question is you say that "Driver instance you

have
created should take care of the page. Whenever a page is loaded
completely

then only it will perform further actions" so what if -

1. sometimes when we play an action, it does not cause page reload,
what will the action (i.e. click) execute, will it automatically
defect the page status and take the right action or something else?
can you explain more internal details?

2. if webdriver can take care of the page load automatically, is there
a way to set the timeout for the page load wait time like selenium1.0?

Assume it doesn't block in those cases, and make use of the
WebDriverWait class and the matching Wait interface.

How it's implemented depends on the browser, but we tend to do some
basic checks before starting an action to see if it's a sensible thing
to do.
