How does @CacheLookup work in WebDriver?

Question

I\'m not sure that I understand the caching principle :

@CacheLookup
@FindBy(how = How.ID, using = namespace + signifLvl)
private WebElement sigLvl;
<         


        

Answer 1

Page Factory works on the principle of configuring the proxies when Page Factory is initialized and every time you use a WebElement it will go and search for the element.

Now what cachelookup does is it stores elements having @cachelookup annotation applied over it and then stores this element for further reference/s. For example:

  public class SearchPage {
 // The element is now looked up using the name attribute,
  // and we never look it up once it has been used the first time
  @FindBy(how = How.NAME, using = "q")
  @CacheLookup
  private WebElement searchBox;
  public void searchFor(String text) {
  // We continue using the element just as before
   searchBox.sendKeys(text);
  searchBox.submit();
   } }

What this annotation does is it stores the value the searchBox element and now there is no need to search for this element on webpage again.
