Parallel ThreadLocal

[M_i]

The app runs, but only one of the two runs or stops in the middle.

I need to use “ThreadLocal” but I can’t.

Can you help me?

	protected static AppiumDriver<MobileElement> driver;

		@Parameters({"device", "apppackage", "activity","version","appiumServer"})
		@BeforeClass
		public void deviceSetUp(String device, String apppackage, String activity, String version, String appiumServer) throws InterruptedException, MalformedURLException, InterruptedException {
			System.out.println("****************************************");
			System.out.println("Setting up device and desired capabilities");
			
			DesiredCapabilities cap = new DesiredCapabilities();
			
			cap.setCapability(MobileCapabilityType.DEVICE_NAME, device);

			cap.setCapability("autowebview","false");
			
			URL url = new URL(appiumServer);

			driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
		}

I used thread local but couldn’t find the driver in @test.

It’s been a week since the challenge… can you help?

MobileElement arrow = driver.findElementByAccessibilityId(“next”);

Can’t find “driver” in this code…

import io.appium.java_client.AppiumDriver;

	@Test
	public void onboarding() throws MalformedURLException, InterruptedException  {
	
		System.out.println("_3_Onboarding Start");
	
		MobileElement arrow = driver.findElementByAccessibilityId("next"); 
 	 
		arrow.click();
		Thread.sleep(2000);
		
		arrow.click();
		Thread.sleep(2000);
		arrow.click();
		Thread.sleep(2000);
		System.out.println("next-done");
	}

@M_i

class _2_Deviceinfo

This is BaseTest. Any test should extend it. Driver inside BaseTest is

public ThreadLocal<AppiumDriver> driver = new ThreadLocal<>();

[M_i]

I can not understand…!

Please look at the image
The Threadlocal driver does not support AccessiBility iD

[Aleksei]

This is threadLocal variable. You can use it directly.

You need use get or set.

E.g. driver.get().findElement…

[M_i]

thank you first
I tried apium while checking your posts and comments written in other places.

So appium is running successfully.
and I found that you have to use threadlocal because of you.

But I think there is another problem
I can’t see “findElementByAccessibilityId()” in my parallel test scrpit as in the image below.

I’ve checked my maven, testng again but can’t find the problem.

I think this is causing “java.lang.NullPointerException”

Do you have any idea how to solve the problem?

Just cast with Android or iOS driver.

((AndroidDriver) driver.get()).find...
