Commands executed on Mink elements may fail for several reasons. ElementWrapper is introduced to automatically handle some of those situations, like StaleElementReference exceptions and ElementNotVisible exceptions. StaleElementReference exceptions are thrown when the command is executed on an element that is no longer attached to the DOM. When that happens the ElementWrapper finds again the element and executes the command again on the new element. ElementNotVisible exceptions are thrown when the command requires the element to be visible but the element is not. When that happens the ElementWrapper waits for the element to be visible before executing the command again. These changes are totally compatible with the current acceptance tests. They just make the tests more robust, but they do not change their behaviour. In fact, this should minimize some of the sporadic failures in the acceptance tests caused by their concurrent nature with respect to the web browser executing the commands. However, the ElementWrapper is not a silver bullet; it handles the most common situations, but it does not handle every possible scenario. For example, the acceptance tests would still fail sporadically if an element can become staled several times in a row (uncommon) or if it does not become visible before the timeout expires (which could still happen in a loaded system even if the components under test work right, but obviously it is not possible to wait indefinitely for them).
