How to use assertEquals in appium by using selenium java

[vaibhav_khachane]

I just tries to compare actual result with expected result , using assertEquals, but getting error. I think i have made basic mistake. provide any example for compare text result

WebElement result= (WebElement)driver.findElementsByXPath("//android.widget.TextView[contains(@resource-id,'formula')]");
Assert.assertEquals(result, "9");

[Lee]

result is a webelement object, you should compare result.getText() and "9"

[vaibhav_khachane]

WebElement result= (WebElement) driver.findElementsByXPath("//android.widget.TextView[contains(@resource-id,'formula')]");
Assert.assertEquals(result.getText(), "9");
I have wrote code above but getting following error
java.util.ArrayList cannot be cast to org.openqa.selenium.WebElement

[Telmo_Cardoso]

findElementsByXPath returns a List. You probably want:

WebElement result= (WebElement) driver.findElementByXPath("//android.widget.TextView[contains(@resource-id,'formula')]");
Assert.assertEquals(result.getText(), "9");

Thanks for quick reply . I have tried but getting following error
java.util.ArrayList cannot be cast to org.openqa.selenium.WebElement

[Telmo_Cardoso]

Post your code please...

[igal_epshtein]

WebElement result= (WebElement) driver.findElementsByXPath("//android.widget.TextView[contains(@resource-id,'formula')]");

findElements return list of WebElements, you are assign it to WebElement ...

You should assign it to List list = driver.findElementsByXPath ....

WebElement result= (WebElement) driver.findElementsByXPath("//android.widget.TextView[contains(@resource-id,'formula')]");

You still have

...findElementsByXPath...

instead of

...findElementByXPath...

notice the 's' on findElements vs findElement

I have made changes but still getting following error

Requested a new session but one was in progress

launch your appium server with parameter

--session-override

or stop and start server before launching your test

[vaibhav_khachane]

getting same error after killing server and restart it again

[vaibhav_khachane]

Its working by using String
String result = driver.findElement(By.className("android.widget.EditText")).getText();

Please tell me how to terminate app forcefully and how to view html result in TestNG

Hi telmo,

How to verify List of texts coming post swipe and have to Assert each text post scroll.
had tried this approach.

public void listOnmenuItemTextViewBurgers() {
String[] expected = {“SomeName”, “Double Meat”, " Avocado Bacon Burger"};

	HashSet<String> uniqueList = new HashSet<String>();
	for (int i = 0; i < 3; i++) {
		List<MobileElement> list1 = listBurgersCategory;
		String text1 = null;
		List<String> textlist = new ArrayList<String>();
		for (int j = 0; j < list1.size(); j++) {
			text1 = list1.get(j).getText();
			textlist.add(text1);
		}
		uniqueList.addAll(textlist);
		list1.clear();
		comlib.HorizontalSwipe(driver, 0.40);
	}
	log.stepLog("**********Verify Burgers Category List***********");
	for (String Burger : uniqueList) {
		Assert.assertEquals(Burger.contains("SomeName"), expected[0]);
	}
}

This approach fails since:
FAILED: VerifyAssertListByOrderScreen
junit.framework.AssertionFailedError:
expected: but was: SomeName
