|
|
* For a {@link Condition} or function, the wait will repeatedly

* the condition has been satisfied. Note the resolution time for a promise
|

*
|
|
* Note, if the provided condition is a {@link WebElementCondition}, then

* to fail the command if the promise does not resolve before the timeout
|

|
|
* _Example:_ Suppose you have a function, `startTestServer`, that returns a

|
* WebElements, WebDriver will use the first element. For example, to find the
|
|
* first visible link on a page, you could write:
|
|
*
|
|
* var link = driver.findElement(firstVisibleLink);
|
|
*
|
|
* function firstVisibleLink(driver) {
|
|
* var links = driver.findElements(By.tagName('a'));
