Interview | @CacheLookup - in Page Object Model | Page Factory

@CacheLookup, as the name suggests helps us control when to cache a WebElement and when not to.

This annotation when applied over a WebElement instructs Selenium to keep a cache of the WebElement instead of searching for the WebElement every time from the WebPage. This helps us save a lot of time.

Syntax:
 @FindBy(how = How.NAME, using = "firstname")
 @CacheLookup
 public WebElement firsNameCached;

Interview question | Page Factory | Lazy loading

Here is the interview question:

As per "Page Factory", all the elements will be initialized at the time of page load.
But in dynamic applications how page factory works?
Ex: Assure a drop down content ( options)  loads on click of the respected select box, how can you implement page factory for this?, as page factory initializes elements at the time of page load only.

Answer:
Lazy load concept.

AjaxElementLocatorFactory is a lazy load concept in Page Factory pattern to identify WebElements only when they are used in any operation
i.e. a timeOut for a WebElement can be assigned to the Object page class with the help of AjaxElementLocatorFactory.

Syntax : ( similer to plain "Page Factory init elemnts"  method )

PageFactory.initElements(new c(driver, 30), this);

If element not found in 30 secs, NoSuchElemementException throws.

happy coding.
