'Assert cannot be resolved' is displayed when i tries to insert an Assert command
String menu1 = driver.findElement(By.xpath("value")).getText();
System.out.println(menu1);
if(Assert.assertEquals(menu1,"About Us"))
{
}
please add the below import statement to your code. it may resolve your issue.
import org.testng.Assert;
assertEquals doesn't return any value.
You can't put inside a if clause. please remove if statement.
just add only the assert statement.
Assert.assertEquals(menu1,"About Us");
