如何在 Selenium Java 中自动单击导航菜单以避免 NoSuchElementException？

Question

我已经实现了一个Selenium Java 程序，我需要在其中自动单击导航菜单。下面是我的代码的实现。

NewCard.java

public class NewCard {
public static void createTopUpRequestNewCard(WebDriver driver) {
    WebDriverWait wait = new WebDriverWait(driver, 20);
    WebElement utilitytopup = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//div[@id='wrapper']/div/ul/li[9]/a")));
    utilitytopup.click();
    WebElement createtopupnewcard = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//a[contains(.,'create top up request (new card)')]")));
    createtopupnewcard.click();
}
}

<a href="#" class="context-menu__link"> create top up request (new card) </a>

我尝试输入CssSelector、Linktext 和XPath，但无济于事。最重要的是，我使用了Selenium IDE 来记录它，上面的屏幕截图是我正在处理的两个元素。尽管如此，尽管尝试了这些定位器，我仍然收到NoSuchElementException。

我可以知道如何解决这个问题吗？

ExpectedConditions of visibilityOfElementLocated() 不能确保元素是可交互的。相反，您需要为element_to_be_clickable() 诱导WebDriverWait，您可以使用以下Locator Strategies：

public class NewCard {
    public static void createTopUpRequestNewCard(WebDriver driver) {
        new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//a[@class='menu__link' and contains(., 'Utility Top Up')]"))).click();
        new WebDriverWait(driver, 20).until(ExpectedConditions.elementToBeClickable(By.xpath("//a[@class='menu__link' and contains(., 'create top up request')]"))).click();
    }
}
