Question

这是我的代码：

 public class Init{
    public static WebDriver driver;
    @BeforeSuite
    public static void init_method1(){
        System.setProperty("webdriver.ie.driver", "//Provide IEDriverLocation//");
        driver = new InternetExplorerDriver();  
    }

}

public class B{
    @FindBy(xpath="XXXXxxxxxx")
    WebElement b_obj;

    public B(){
        PageFactory.initElements(Init.driver, this);
    }   

    public void b_method1(){
        b_obj.sendkeys();
    }

}

public class C{
    B b =  new B();
    @Test
    public void c_method1(){
        b.b_method1;
        }
}

在TestNG.xml中，

<class name= "Package1.Init"></class>
<class name= "Package1.C"></class>

错误：
