Change default strategy for @HowToUseLocators programatically

Inizia leggendo la sezione Page-objects.md e il Javadoc di HowToUseLocators, quindi esamina come PageFactory.initElements e AppiumFieldDecorator applicano le strategie di localizzazione. Definisci come un valore predefinito a livello di pagina debba coesistere con le annotazioni a livello di elemento e conferma che le strategie esplicite esistenti rimangano efficaci. Il lavoro è completato quando un’unica configurazione a livello di pagina funziona per gli elementi altrimenti privi di annotazioni ed è coperta da test.

Description

Appium provides a way to use multiple locator startegies via @HowToUseLocators annotation. The default starategy is set to LocatorGroupStrategy.CHAIN, so if we want to use the alternative strategy i.e. LocatorGroupStrategy.ALL_POSSIBLE, then we need to annotate our WebElements via

@HowToUseLocators(androidAutomation = ALL_POSSIBLE, iOSAutomation = ALL_POSSIBLE)
@FindAll{@FindBy(someStrategy1), @FindBy(someStrategy2)}) 
@AndroidFindBy(someStrategy1) @AndroidFindBy(someStrategy2) 
@iOSFindBy(someStrategy1) @iOSFindBy(someStrategy2) 
RemoteWebElement someElement;

More on this here:
https://github.com/appium/java-client/blob/master/docs/Page-objects.md#--any-possible
https://www.javadoc.io/doc/io.appium/java-client/latest/io/appium/java_client/pagefactory/HowToUseLocators.html

The problem is that we have many WebElements and almost all of them use the LocatorGroupStrategy.ALL_POSSIBLE. This means that for each of the WebElement we have to write an additional line to annotate it with @HowToUseLocators(androidAutomation = ALL_POSSIBLE, iOSAutomation = ALL_POSSIBLE). This causes alot of repetitive code which could be avoided by changing the default strategy in one place.

I am looking for a way to set the default strategy at single place, so it can be applied to all the WebElements unless it is annotated differently.

Is there a way to achieve this currently? If not, would you be interested in adding this functionality to page objects?

Environment

• Appium Java client 9.1.0

Details

Perhaps we can set this via following ways by passing an extra parameter which changes the default strategy for web elements of page:

PageFactory.initElements(new AppiumFieldDecorator(searchContext, 
	    new TimeOutDuration(15, TimeUnit.SECONDS),
            HowToUseLocators(androidAutomation = ALL_POSSIBLE, iOSAutomation = ALL_POSSIBLE)
            ), 
           pageObject
);
