Appium Java client 8.3.0 not detecting @AndroidFindBy and @iOSXCUITFindBy

IMOBILETester · July 10, 2023, 4:06am

appiumDriver = (AppiumDriver) driver;
PageFactory.initElements(new AppiumFieldDecorator(appiumDriver, Duration.ofSeconds(30)), this);

I tried above and i can see it’s taking AppiumDriver instead of WebDriver. But same error when i use @AndroidFindBy
rg.openqa.selenium.InvalidSelectorException: Unsupported CSS selector ‘*[name=‘xxxxx’]’. Reason: ‘‘name’ is not a valid attribute. Supported attributes are ‘checkable, checked, clickable, enabled, focusable, focused, long-clickable, scrollable, selected, index, instance, description, resource-id, text, class-name, package-name’’

But you can not casting the driver to the appium driver, but declare it as such?

IMOBILETester · July 10, 2023, 4:48am

Tried that. I removed my base class extends pageObject class. but throwing error like blow

java.lang.NullPointerException: Cannot invoke “xxx.Page.click_Btn(String)” because “this.page” is null. How do i invoke page class from step class without PageObject class extends?

razz_el · July 14, 2023, 2:37am

I have exactly same problem using PageFactory.

Same code works when I use AppiumBy or even By but fails when I try to use Page Object Model concept. It always points toward CSS selector in java console and appium console.

Maybe I will ask different question - I don’t have to use POM concept. I have to write a single test, which will choose pick from one of two locators. I was using
AndroidFindBy
iOSFindBy
public WebElement X

but I don’t know what happend, it stopped working with iosXCUITFindBy and AndroidFindBy in Appium 8.3.0

Now I am using:
FindAll ({
FindBy xpath
FindBy xpath
)}
And the script chooses whatever is available, but I am literally limited to xpath. I tried different things, waits, AppiumFieldDecorator (which gives me NullPointerExeption), using specific IOSDriver/AndroidDriver instead of Appium Driver. I cant find solution for that for MONTHS now. topics are literally dying. Is this Appium version bugged or what?

IMOBILETester · July 14, 2023, 7:47am

Thanks for suggestion:) It works for me too. Just wanna confirm FindAll is not working with id? Is it works only with xpath?

razz_el · July 14, 2023, 10:02am

It works only with xpath.

But it is not a solution. It is not even a workaround. Thats like riding a bike with one leg.

I spent countless hours looking for a solutions and most of the topic have either:

appium field decorator (sometimes works)
wait (never worked)
incorrect passing of the driver (never worked)

99% are unsolved. The truth is that is the bug and nobody knows the real reason for it.

The workaround would be using something else but I cant find any alternative to the need I posted - idk maybe try catch blocks for each elements?

That sucks.

Aleksei · July 14, 2023, 10:18am

the real reason in your code. put it all into git. give link. it should help more to understand your issue.

razz_el · July 14, 2023, 10:24am

I was hoping to hear something like that. I will do that ~2hrs

remove static here and EVERYWHERE in elements.

replace with

PageFactory.initElements(new AppiumFieldDecorator(driver, Duration.ofSeconds(sec)), this);

better use constructor like

public class LoginPage {
    @iOSXCUITFindBy(id = "Allow")
    private WebElement allowButton; // elements ARE private. it is better not share them outside class. ONLY actions are public!

    @iOSXCUITFindBy (id = "xxx")
    private WebElement logo;

   public LoginPage(AppiumDriver driver) {
        PageFactory.initElements(new AppiumFieldDecorator(driver, Duration.ofSeconds(sec)), this);
    }
}

after open driver use something like:

LoginPage loginPage = new LoginPage(driver);
// now any actions
loginPage
.setEmail("my_email")
.tapLoginButton()...

razz_el · July 14, 2023, 1:23pm

Yes Sir, working on it, I will let you know in a minute

razz_el · July 14, 2023, 2:14pm

I used getters to get the private values.

Anyway, I added whatever you posted here and:

using appium field decorator gives me NPE
using constructor with initElements gives me NPE
using default constructor and calling the method gives me NPE

NPE is in the line where it checks if the element is displayed

That’s my LoginPage now:

public LoginPage(AppiumDriver driver){
        PageFactory.initElements(new AppiumFieldDecorator(driver, Duration.ofSeconds(10)),LoginPage.class);
}
@iOSXCUITFindBy(xpath= "//XCUIElementTypeOther[@name=\"Sauce Labs Backpack\"]")
private WebElement backpack;
@iOSXCUITFindBy(accessibility = "longpress reset app")
private WebElement logo;

public WebElement getLogo(){
        return logo;
}

public WebElement getBackpack(){
        return backpack;
}

And that is my main (without caps)

 AppiumDriver driver = new AppiumDriver(url, caps);

LoginPage loginPage = new LoginPage(driver);

Thread.sleep(3000);

System.out.println(loginPage.getLogo().isDisplayed());
System.out.println(loginPage.getBackpack().isDisplayed());

EDIT:

I made it work, with your requirements, but with a slight change. It was not working with LoginPage.class in initElements method, but I had to use “this”.

I’ve added locators for Android and it worked.

@Aleksei, Please accept my sincere apologies for ever doubting the Appium Team and saying such a bad words.

@IMOBILETester try to follow Aleksei’s advices, but use “this” in the method. If not, let me know, I will share the working code with you.

IMOBILETester · July 15, 2023, 4:22am

Can anybody help me to resolve mine?

1)I have initialised iOS driver with AppiumDriver.

XCUITestOptions ios =
new XCUITestOptions()
.setPlatformName(“iOS”)
.setDeviceName(“iPhone 14 Plus”)
.setOrientation(PORTRAIT)
.setBundleId((“xxx”))
.setAutomationName(“XCUITest”)
.setNoReset(true)
.setApp(app.getAbsolutePath());

driver = new AppiumDriver(url, ios);

Base class which extends pageObject to initiate driver

public class baseClass extends PageObject {

public BaseClass(WebDriver driver) {
    PageFactory.initElements(new AppiumFieldDecorator(driver, Duration.ofSeconds(30)), this);
}.  **// I can't use AppiumDriver as parameter as PageObject din't have AppiumDriver. So it will throw error.** But still it's invoking AppiumDriver only even in my page class when i try to print the driver name

Page class

public class page extends baseClass {

public page(WebDriver driver) {
    super(driver);   //** I can't use AppiumDriver as parameter as PageObject din't have AppiumDriver. So it will throw error.** But still it's invoking AppiumDriver only even in my page class when i try to print the driver name

}

@iOSXCUITFindBy(accessibility = "Account")
public WebElement account;

public void click_Btn() {
account.click();
}

4)POM

Can anybody please correct my code?

Aleksei · July 15, 2023, 7:13am

Try

PageFactory.initElements(new AppiumFieldDecorator((AppiumDriver) driver, Duration.ofSeconds(30)), this);

IMOBILETester · July 15, 2023, 7:49am

Thanks @Aleksei for suggestion. i tried above ,no luck same error from appium

eventhough i gave accessibility or xpath in locator.

Aleksei · July 15, 2023, 11:20am

So what issue? Element not found? Share page source.

Yes, org.openqa.selenium.NoSuchElementException: Timed out after 2 seconds. Element not found It’s thrown.I increased time,but still same issue.

In my pagesource ,it says accessible false. but in appium inspector i can see it’s true for same locator. Is that the issue?

IMOBILETester · July 25, 2023, 2:37am

resolved this issue by passing -Dcontext=ios in property and it’s detecting properly. Not sure is there any other way to achieve this?
