How do I create Page Object Model that works for Android AND iOS

[Matt882]

I have created a Page Object in Java that is currently working for an Android app as shown below:

public class MattVerifyPage extends PageObject{

private AppiumDriver driver = FrameworkInitialize.driver;

By verifyTitle = By.xpath("/hierarchy/android.widget.TextView");

public void verifyTitle(String expectedTitle){

    String actualTitle = driver.findElement(verifyTitle).getText();

However, I need it to work an the Android app and the iOS app, the xpath selector is different for both apps. I think I need to do something like this:

@AndroidFindBy(xpath = “androidxpath”)
@iOSFindBy(xpath = “iOSxpath”)
public MobileElement verifyTitle ;

However, when I do this, the driver.findElement line (String actualTitle = driver.findElement(verifyTitle).getText() shows the following error:

findElement
(org.openqa.selenium.By)
in DefaultGenericMobileDriver cannot be applied
to
(io.appium.java_client.MobileElement)

I think I am comparing AppiumElements with SeleniumElements but I’m not sure how to resolve it.

Any help would be greatly appreciated.

Thanks

Matt

@Matt882 when you use Appium annotation they already do all job to find element. All left is use it.

@AndroidFindBy(xpath = “androidxpath”)
@iOSFindBy(xpath = “iOSxpath”)
public MobileElement verifyTitle ;

String actualTitle = verifyTitle.getText();

first example from google search to see all PageObject - > https://blog.testproject.io/2018/07/31/page-object-model-appium-java-android/

or some example at java-client Appium code: https://github.com/appium/java-client/blob/master/src/test/java/io/appium/java_client/pagefactory_tests/MobileBrowserCompatibilityTest.java

Thanks Aleksei. I have changed my page object to look like this:

public class MattVerifyPage extends PageObject{
private AppiumDriver driver;

public MattVerifyPage(AppiumDriver driver) {
    this.driver = driver;
    PageFactory.initElements(new AppiumFieldDecorator(driver), this);
}


@AndroidFindBy(xpath = "Androidxpath")
@iOSFindBy(xpath = "iOSxpath")
public MobileElement verifyTitle ;


public void verifyTitle(String expectedTitle){

    String actualTitle =verifyTitle.getText();

}

In my test step file the page is instantiated using this code:

MattVerifyPage VerifyPage = new MattVerifyPage(driver);

However, when I run the test I get the error shown below. I am also using Serenity so if there is no obvious problem with my code above it must be a Serenity issue:

It is problem in your serenity/cucumber. Your example works correctly in pure Java.

One suggestion is move constructor to basePage.
