在同一类文件的第二个@test方法中使用数据提供程序的java未成功运行

Question

在我的要求，我有“添加”按钮在屏幕上的“C类”。它打开弹出式模块。在那里我可以添加更多的值并保存

我的代码使用一个带有数据提供程序迭代的@Test方法运行。但在一次迭代后失败了。因此，我用数据提供者创建了一个额外的@test方法

成功运行第一个@test方法后获取代码失败。找不到第一个元素属于第二个@test方法

Failed: columns("Encounter", "account", "Encounter")
org.openqa.selenium.TimeoutException Expected condition failed:
waiting for visibility of element located by By.xpath:
//*[@id='txtDisplayName'] (tried for 4 second(s) with 500 milliseconds interval).

public class classc extends classb {
    
    @Test
    public void Create()
    {
    // Redirection to the screen
        obj1.actiononMenu(driver, wait, "//abbr[@class='ti-settings']", "//samp[text() = 'Focus']", "//li[2]/ul/li[1]/a");

    long focusauditTimetaken = (long) obj1.javatimeout(driver);
        this.wait = obj1.explicitWait(driver, (int) focusauditTimetaken);

        // Clicking add button
        WebElement addButton = obj1.selectElement(wait, "//div[2]/button");
        obj1.clickElement(addButton);
    
    }
    
    @Test(dataProvider = "addingColumns")
    public void columns(String displayName, String columnName, String uniqueName)
    {
        // Passing first value from the DataProvider (displayName)  
        WebElement displayColumn = obj1.selectElement(wait, "//*[@id='txtDisplayName']");
        obj1.clickElement(displayColumn);
        obj1.sendtext(displayColumn, displayName);
        
    // Passing second value from the DataProvider (columnName)  
        WebElement columnDropdown = obj1.selectElement(wait, "//div[contains(text(), 'Select Column Name')]");
        obj1.clickElement(columnDropdown);
        
        obj1.dropdownfilter(driver, wait, "//div[@class='filter']/input", columnName);
        
    // Passing thrid value from the Data Provider (uniqueName)
        WebElement uniqueDropdown = obj1.selectElement(wait, "//div[contains(text(), 'Select Column')]");
        obj1.clickElement(uniqueDropdown);
        
        obj1.dropdownfilter(driver, wait, "//div[@class='filter']/input", uniqueName);
        
    // Save first set values 
        WebElement addcolumnButton = obj1.selectElement(wait, "//button[@class='button create hvr-glow hvr-icon']");
        obj1.clickElement(addcolumnButton);
        
        
    }
    
    @DataProvider(name = "addingColumns")
    public Object[][] addColumns()
    {
        return new Object[][]
                {
            {"AA","BB","CC"},
            {"11","22","33"}
                };
    }
            
}

c类扩展了B类

public class ClassB extends ClassA{

@Test
public void project() {
    
    try {
        obj1.implicitWait(driver, 10);          
        WebElement groupName = wait.until(ExpectedConditions.visibilityOf(driver.findElement(By.xpath("//*[@class='placeholder']"))));
        groupName.click();
        
        WebElement inputText = wait.until(ExpectedConditions.visibilityOf(driver.findElement(By.xpath("//*[@class='filter']//input"))));
        inputText.click();
        inputText.sendKeys("Par");
        inputText.sendKeys(Keys.DOWN);
        inputText.sendKeys(Keys.ENTER);
        
        long timetaken = (long) obj1.javatimeout(driver);
        this.wait = obj1.explicitWait(driver, (int) timetaken); 
        
    } catch (Exception e) {
        System.out.println("Project group not selected " +e);
        // TODO: handle exception
    }
    
}

B类扩展了A类

public class ClassA{
    
    WebDriver driver;
    WebDriverWait wait;
    
    Commonclass obj1 = new Commonclass();
    
    @BeforeSuite
    public void callbrowser()
    {
        this.driver = obj1.selectBrowser(driver, "Chrome");
        
    }
    
    @Test
    public void login()
    {
        driver.get("https://Link Goes here");
        
        long timetaken = (long) obj1.javatimeout(driver);
        wait = obj1.explicitWait(driver, (int) timetaken);
        
        WebElement signin = obj1.selectElement(wait, "//*[@id='txtSigninID']");
        obj1.sendtext(signin, "My Name");
            
        WebElement password = obj1.selectElement(wait, "//*[@id='txtPassword']");
        obj1.sendtext(password, "my password");
        
        WebElement submit = obj1.selectElement(wait, "//*[@name='btnSignIn']");
        obj1.clickElement(submit);
    }
    
    
}

如果我有一个@test方法，那么整个代码都会运行。为什么单个类中的两个@test方法不起作用。我正在添加testng。下面是xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">
