Description

when I use 5.0.0beta1 java-client,I can't find any element.the wrong is:

java.lang.ClassCastException: org.openqa.selenium.remote.RemoteWebElement cannot be cast to io.appium.java_client.MobileElement

Environment

• java client build version or git revision if you use some shapshot:5.0.0 beta1 from maven
• Appium server version or git revision if you use some shapshot:1.6.0 and 1.6.3
• Mobile platform/version under test:ios 10.2,xcode 8.2.1
• Real device or emulator/simulator:real

Details

public class Test {

	private IOSDriver<MobileElement> driver = null;

	@BeforeClass
	public void beforeclass() {
		DesiredCapabilities capabilities = new DesiredCapabilities();
		capabilities.setCapability(MobileCapabilityType.PLATFORM_NAME, "IOS"); 
		capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, "XCUITest"); 
		capabilities.setCapability(MobileCapabilityType.DEVICE_NAME, "111"); 
		capabilities.setCapability(MobileCapabilityType.APP, "my app"); 
		capabilities.setCapability(MobileCapabilityType.UDID, "my udid"); 

		try {
			driver = new IOSDriver<MobileElement>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
		} catch (MalformedURLException e) {
			e.printStackTrace();
		}
	}

	@Test
	public void element() throws InterruptedException {
		Thread.sleep(10000);
		MobileElement element = (MobileElement) driver.findElement(By.className("XCUIElementTypeScrollView"));
		element.getSize();
		Thread.sleep(10000);
	}

	@AfterClass(alwaysRun = true)

I have exactly the same issue.

Appium version (or git revision) that exhibits the issue: 1.6.1-beta
Desktop OS/version used to run Appium: OS X 10.12.2
Node.js version (unless using Appium.app|exe): 6.9.1
Mobile platform/version under test: iOS 10.0
Real device or emulator/simulator: simulator
Appium CLI or Appium.app|exe: Appium CLI
Coding language: java-client 5.0.0-BETA1

I am upgrading from iOS 9.3 to 10.0. So I changed to xcode8 and got the new java-client.
I was frighten to have lot of problems with the migration from the uiautomation to the NSPredicats, but first there occurs some strange cast errors.

AppiumDriver<IOSElement> driver = new IOSDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), caps);
List<IOSElement> allTravelActions = driver.findElementsById("travelActions.title");
allTravelActions.get(0).click();

The last line with .click() leads to the following error:

org.openqa.selenium.remote.RemoteWebElement cannot be cast to io.appium.java_client.ios.IOSElement
And also in a for each loop this error occurs

ArrayList<IOSElement> top10list = driver.findElementsById("stationSearch.station.name");
for (IOSElement item : top10list){
}

Debugging shows me, that "driver.findElementsByAccessibilityId" returns a List of RemoteWebElements (screenshot01 + 02)

Why do I get RemoteWebElements from my AppiumDriver ?

@iriszhang1986
Guys, could you invoke the

driver.getSessionDetails()

and show the result map here?

[TikhomirovSergey]

It is defenetely the bug but now I'm trying to get my local Mac machine fixed

[derunewige]

At which place in the code?

[saikrishna321]

@derunewige

AppiumDriver<IOSElement> driver = new IOSDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), caps);
driver.getSessionDetails();

@derunewige @saikrishna321 @SrinivasanTarget
It seemst that there are two problems.
The first problem is that we didn't expect that session can't contain any information about platform/automation. I think we can resolve it on the client side.

The second probled. Why does it not contain that info when app is started on a real iPhone/iPad? May be there is server side bug.

Any thoughts?

[saikrishna321]

@TikhomirovSergey

The first problem is that we didn't expect that session can't contain any information about platform/automation

All the details are received from server including the automation and platform and lot more. Sample response

"status": 0,
 "value": {
 "platform": "LINUX",
 "webStorageEnabled": false,
 "takesScreenshot": true,
 "javascriptEnabled": true,

 },
 "sessionId": "0ac42e16-65c3-40ec-bcf0-fae7d9dd9a4a"
}

let me try on real device

[SrinivasanTarget]

I see Automation Name or Platform Details is not coming up in session details at times when we run on XCUITMode (Only in XCUITMode) even on simulators.

[SrinivasanTarget]

@iriszhang1986 @derunewige Please do a run without below capabilities and send us entire server logs.

caps.setCapability(IOSMobileCapabilityType.AUTO_ACCEPT_ALERTS, Boolean.TRUE);
caps.setCapability(IOSMobileCapabilityType.SEND_KEY_STRATEGY, SendKeyStrategy.SET_VALUE);
caps.setCapability(MobileCapabilityType.NO_RESET, Boolean.TRUE);
caps.setCapability(MobileCapabilityType.FULL_RESET, Boolean.FALSE);

Between i'm debugging it as well.

[saikrishna321]

@SrinivasanTarget @TikhomirovSergey with legacy driver i get the below response, which looks fine to me. May be as srini mentioned could be with XCUITest

public void iosSetup() throws MalformedURLException {
 caps.setCapability(MobileCapabilityType.UDID, "xxx");
 caps.setCapability(MobileCapabilityType.DEVICE_NAME, "iPhone SE");
 caps.setCapability(MobileCapabilityType.PLATFORM_VERSION, "9.3.2");
 caps.setCapability(IOSMobileCapabilityType.BUNDLE_ID, "xxx");
 caps.setCapability(MobileCapabilityType.APP,"/Users/saikrisv/Downloads/debug.ipa");
 driver = new IOSDriver<MobileElement>(new URL("http://0.0.0.0:4723/wd/hub"), caps);

 }

{"webStorageEnabled":false,"locationContextEnabled":false,"browserName":"","platform":"MAC","javascriptEnabled":true,"databaseEnabled":false,"takesScreenshot":true,"networkConnectionEnabled":false,"app":"/Users/saikrisv/Downloads/XXX-debug.ipa","bundleId":"XXX","udid":"XXXXX","platformName":"iOS","deviceName":"iPhone SE","platformVersion":"9.3.2","desired":{"app":"/Users/saikrisv/Downloads/XXX-debug.ipa","bundleId":"XXX","udid":"XXX","platformName":"iOS","deviceName":"iPhone SE","platformVersion":"9.3.2"}}

[SrinivasanTarget]

Yes it is fine in legacy driver and UIAutomator2 mode but Automation Name is not coming if we didn't specify it explicitly in desired caps and running on iOS10 sims.
