Class WebDriverWait

java.lang.Object

org.openqa.selenium.support.ui.WebDriverWait

All Implemented Interfaces:

Wait<org.openqa.selenium.WebDriver>

public class WebDriverWait
extends Object
implements Wait<org.openqa.selenium.WebDriver>

An implementation of the Wait interface that makes use of WebDriver. The expected usage is in conjunction with the ExpectedCondition interface.

Because waiting for elements to appear on a page is such a common use-case, this class will silently swallow NotFoundException whilst waiting.

Constructor Detail

WebDriverWait

public WebDriverWait(org.openqa.selenium.WebDriver driver,
                     long timeOutInSeconds)

Parameters:

driver - The WebDriver instance to pass to the expected conditions

timeOutInSeconds - The timeout in seconds when an expectation is called

WebDriverWait

protected WebDriverWait(org.openqa.selenium.support.ui.Clock clock,
                        org.openqa.selenium.WebDriver driver,
                        long timeOutInSeconds,
                        long sleepTimeOut)

Parameters:

clock - The clock to use when measuring the timeout

driver - The WebDriver instance to pass to the expected conditions

timeOutInSeconds - The timeout in seconds when an expectation is

sleepTimeOut - The timeout used whilst sleeping. Defaults to 500ms called

Method Detail

until

public <T> T until(com.google.common.base.Function<org.openqa.selenium.WebDriver,T> isTrue)

Description copied from interface: Wait

Implementations should wait until the condition evaluates to a value that is neither null nor false. Because of this contract, the return type must not be Void.

If the condition does not become true within a certain time (as defined by the implementing class), this method will throw a non-specified Throwable. This is so that an implementor may throw whatever is idiomatic for a given test infrastructure (e.g. JUnit4 would throw AssertionError.

Specified by:

until in interface Wait<org.openqa.selenium.WebDriver>

Type Parameters:

T - the return type of the method, which must not be Void

Parameters:

isTrue - the parameter to pass to the ExpectedCondition

throwTimeoutException

protected void throwTimeoutException(String message,
                                     Exception lastException)

Override this method to throw an exception that is idiomatic for a given test infrastructure. E.g. JUnit4 should throw an AssertionError
