Parameter 'browser' is required by @Configuration on method setUp but has not been marked @Optional or defined

[meetparag81]

Hello,
I am getting "Parameter 'browser' is required by @configuration on method setUp but has not been marked @optional or defined" message while running my test class
I have extended my base class to test class as well as I have added browser and url values in testng xml
Please refer code below

Base class
public class Baseclass_1
{
public static WebDriver driver;

@Parameters({"browser","url"})
@BeforeClass
public  void setUp(String browser,String url)
{
	if(browser.equalsIgnoreCase("firefox"))
	{
		System.setProperty("webdriver.gecko.driver","G:\\Javaprogramming\\Selenium\\Selenium Setup\\geckodriver.exe");
		driver=new ChromeDriver();
		
	}
	else if(browser.equalsIgnoreCase("chrome"))
	{
		
		
	}
	driver.get(url);
	driver.manage().window().maximize();
	
	driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
	
	
}

@AfterClass
public void tearDown()
{
	driver.quit();
		
}

===================================================================
Test class
public class FBTestnew extends Baseclass_1
{
WebDriver driver;

@Test	
public void LogintoFB()
{
	
	// Baseclass_1.setUp("firefox","https://www.facebook.com/");
	FBHome FB_Hpme =PageFactory.initElements(driver, FBHome.class);
	FB_Hpme.LogintoFB("username", "password");
	
}

}

Testng xml

	<classes>
		<class name="Com.Browser.Baseclass_1" />
	</classes>
</test>

But running a test class or testng xml The browser is not launched. Execuring RunAs TestNG class from test class following error seen

FAILED CONFIGURATION: @BeforeClass setUp
org.testng.TestNGException:
Parameter 'browser' is required by @configuration on method setUp but has not been marked @optional or defined

Where as on running testng by executing Run As TestNG Suite, following error seen.

Hi meetparag81,
Your are getting this error because you must be executing Baseclass_1.java file. You need to execute Testng XML file.

Thank you!

Hey, I am also getting this error even I am executing my Testng.xml file.
Please help.

Hi,
Since you are sending browser and url parameters, you need to also add Parameter tag in Testng.xml file after "test" tag.

<parameter name="browser" value="chrome"/>
<parameter name="url" value="https://www.google.com"/>

Please find below code format in Testng.xml file:

<suite name="Sample suite">
  <test thread-count="5"
   name="Test `name">`
   <parameter name="browser" value="chrome"/>
   <parameter name="url" value="https://www.google.com"/>
   <classes>
      <class name="Packagename.Classname"/> 
    </classes>
   </test>
   </suite>

@meetparag81 In Testng.xml file use standartd DTD type its causing the problem. In my case I was getting same problem as mentioned in the main question, Testng.xml file was generated at runtime and it was missing the below DTD after adding this to the Testng.xml the problem gone away

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

Hi @AutomationBatch2019, can you share the code snippet/repo for your test?

Hi @AutomationBatch2019,

From the shared snippet, it looks like you are having issues initiating browser drivers on your local system.

System.setProperty("webdriver.chrome.driver", "/home/ambrish/Lockdown_Tets/SeleniumPractice/drivers/chromedriver");

System.setProperty("webdriver.gecko.driver","/home/ambrish/Lockdown_Tets/SeleniumPractice/drivers/geckodriver");

This repository contains sample code to run tests on BrowserStack's cloud infrastructure using TestNG.
