        WebElement signout=driver.findElement(By.xpath("//a[@id='nav-item-signout']/span"));
        signout.click();
        Reporter.log("Successfuly signout.......",true);
        driver.quit();
    }
}

When I run this programme using TestNG script, I get the following error:

Parameter 'userName' is required by @Test on method enterCreditial but has not been marked @Optional or defined in C:\Users\jahansalia\AppData\Local\Temp\testng-eclipse-1960767273\testng-customsuite.xml

Answer 1

I looks like you are not using testng.xml

The list of variables used to fill the parameters of this method. These variables must be defined in your testng.xml file. For example

@Parameters({ "xmlPath" })
@Test
public void verifyXmlFile(String path) { ... }

and in testng.xml you need to give detail like this:

<parameter name="xmlPath" value="account.xml" />
