TestNg [TestNG]找不到测试。 DataProvider注释上没有任何运行错误

Question

我试图使用getExcelData函数从excel文件中获取测试数据，该函数收集ArrayList对象中的数据，并在执行代码的testclass中的下面。

下面是我的代码：

public class roughTest {
    public WebDriver driver;

    @BeforeMethod
    public void setUp() {

        System.setProperty("webdriver.chrome.driver", "D:\\geckodriver.exe");
        WebDriver driver = new FirefoxDriver();     
        driver.manage().window().maximize();
        driver.manage().deleteAllCookies();

        driver.get("TEST URL LINK");
    }

    @Test(dataProvider="getData")
    public void form(String firstname,String lastname,String date,String continent) {                   
        driver.findElement(By.name("firstname")).clear();
        driver.findElement(By.name("firstname")).sendKeys(firstname);

        driver.findElement(By.name("lastname")).clear();
        driver.findElement(By.name("lastname")).sendKeys(lastname);

        driver.findElement(By.xpath("(.//input[@type='text'])[4]")).clear();
        driver.findElement(By.xpath("(.//input[@type='text'])[4]")).sendKeys(date);

        Select s = new Select(driver.findElement(By.name("continents")));       
        s.selectByVisibleText(continent);

        System.out.println("Value entered successfully");
    }

    @DataProvider
    public Iterator<Object[]> getData() {
        ArrayList<Object[]> testData = getDataFromExcel.getExcelData();
        return testData.iterator();         
    }

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