org.safs.selenium.ThreadedSelectWindow

All Implemented Interfaces:

Used to workaround a defect in Selenium's selectWindow method. The method sometimes locks-up indefinitely if the sought item is still being loaded or otherwise is not yet ready for testing.

Method Detail

run

public void run()

Implements the Runnable Interface. Attempt a selenium.selectWindow(target_id) call. This should be executed via a call to a new Thread using a ThreadedSelectWindow instance and then invoking start() on that new Thread instance.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread

isSelected

public boolean isSelected()

Returns:

true if the target item was found within the timeout period.

isSearching

public boolean isSearching()

Returns:

true if the search is still in-progress.

searchSeconds

public long searchSeconds()

Returns:

how long the search took, or has taken so far, in seconds.
