# Wait until the test condition is true or a timeout occurs. Useful for waiting
# on a server response or for a ui change (fadeIn, etc.) to occur.

# @param testFx javascript condition that evaluates to a boolean,
# it can be passed in as a string (e.g.: "1 == 1" or "$('#bar').is(':visible')" or
# as a callback function.
# @param onReady what to do when testFx condition is fulfilled,
# it can be passed in as a string (e.g.: "1 == 1" or "$('#bar').is(':visible')" or
# as a callback function.
# @param timeOutMillis the max amount of time to wait. If not specified, 3 sec is used.
