Question

我正在@Test中运行浏览器实例（dataprovider ..方法。但是我无法将驱动程序实例传递给Test方法，

这是我的代码，在最后一个语句中我得到一个零点异常。

我的问题是，如何将驱动程序实例传递给测试方法

@Test (dataProviderClass=GetData.class)

public class createUserPageTest {

private WebDriver driver;
private String baseUrl;
private StringBuffer verificationErrors = new StringBuffer();
private MailCode openMail;

@BeforeMethod
public void setUp() throws Exception {
driver = new FirefoxDriver();
baseUrl = “http://demo.mysite.com”;
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.get(baseUrl + “/pageLink/Home.action”);
}
@Test(dataProvider=”RegisterUserStage1″)
public void NewUsrStage1(String name,String email,String password)
{
CreateUserPage createuser = PageFactory.initElements(driver, CreateUserPage.class);
createuser.CreateUserStage1(driver,name,email,password);
try {
openMail.testValidateEmail(driver);

显示的错误消息是

我的DataProvider名称如下

@DataProvider(name="RegisterUserStage1")
    public static Object[][] getTestData() throws Exception
    {
        Object retObject[][]=getTableArray("src\\resource\\TestData.xls", 0, "NewUserStage1");
        return retObject;
    }
