java - java selenium中的下拉选择问题

Question

我正在尝试自动执行结帐场景。从购物车的下拉菜单中选择值(value)时遇到问题。请查找步骤:

1. 搜索项目并选择该项目
2. 选择尺寸和数量
3. 点击“添加到购物车”
4. 前往购物车
5. 尝试更新数量。从下拉列表中选择 10+，然后输入数量> 10，然后单击更新。我在第 5 步中遇到问题。它只是单击数量，但没有下拉列表显示来选择选项。也没有错误。

 driver.get("https://www.amazon.com/");
 driver.manage().timeouts().implicitlyWait(20L, TimeUnit.SECONDS);
 driver.manage().window().maximize();
 driver.findElement(By.xpath("//*[@id='twotabsearchtextbox']")).sendKeys("football");
 Thread.sleep(2000);
 driver.findElement(By.xpath("//*[@id='issDiv0']")).click();
 driver.findElement(By.xpath("//*[@id='result_0']/div/div/div/div[2]/div[2]/a/h2")).click();
 driver.findElement(By.xpath("//*[@id='native_dropdown_selected_size_name']")).sendKeys("Junior");
 Thread.sleep(3000);
 driver.findElement(By.xpath("//*[@id='quantity']")).sendKeys("2");
 driver.findElement(By.xpath("//*[@id='add-to-cart-button']")).click();
 driver.findElement(By.xpath("//*[@id='hlb-view-cart-announce']")).click();
 driver.findElement(By.xpath("//*[@id='a-autoid-2-announce']/span[2]")).click()​;
 List<WebElement> elements = driver.findElements(By.className("a-dropdown-item quantity-option"));
 System.out.println(elements.size());
 for (WebElement el : elements) {
 System.out.println(el.getText());
 }

我能够使用下面的测试获得数量下拉菜单来选择一个值。我通过几种方式修改了您的初始实现:

功能修改

• 将提供的 By.xpath 查找更新为 By.id(如果可能)
• 在 Select 装饰器中封装下拉 WebElement 引用，并使用 byVisibleText 方法进行选择。
• 删除了对 Thread.sleep 的调用，以代替 WebDriverWait，这可以在查找之间更一致地应用计时条件。

外观修改

• 用户输入数据已提取到命名的字符串变量

• 所有By查找均已提取到命名变量。

    // Entry values.

    String purchaseQtyVisibleText = "2";

    // "By" locators used for process.

    WebDriverWait noThreadSleep = new WebDriverWait(driver, 15);
    noThreadSleep.pollingEvery(250, TimeUnit.MILLISECONDS);

    // Enter the search term
    noThreadSleep.until(ExpectedConditions.visibilityOfElementLocated(searchFieldBy)).sendKeys(searchForFootball);
