Question

使用下面的代码，我试图打开一个链接页面，然后转到移动部分，并根据名称顺序对项目进行排序。现在我想检查移动设备是否按名称按字母顺序排序。我试图将下面的列表转换为arraylist，但无法检查打印的元素是否按升序排列，请帮助

最简单的方法是抓住产品列表，遍历它们，然后查看当前产品名称（String）是否比使用{{3的上一个产品名称“更大” }}

我会为您可能在此页面重复的常见任务编写一些函数。

public static void sortBy(String sortValue)
{
    new Select(driver.findElement(By.cssSelector("select[title='Sort By']"))).selectByVisibleText(sortValue);
}

public static List<String> getProductNames()
{
    List<String> names = new ArrayList<>();
    List<WebElement> products = driver.findElements(By.cssSelector("ul.products-grid h2.product-name"));
    for (WebElement product : products)
    {
        names.add(product.getText());
    }

    return names;
}

public static boolean isListSorted(List<String> list)
{
    String last = list.get(0);
    for (int i = 1; i < list.size(); i++)
    {
        String current = list.get(i);
        if (last.compareToIgnoreCase(current) > 0)
        {
            return false;
        }

        last = current;
    }

    return true;
}

注意：您应该使用JUnit或TestNG作为断言而不是编写自己的断言，因为它使得它变得更加容易（并且您不必编写和调试自己的断言，这样可以节省时间）。我在下面写的代码是使用TestNG。使用像TestNG这样的库时，您可以看到下面的代码更短（和更简单）。

String url = "http://live.guru99.com/index.php";
driver.navigate().to(url);

Assert.assertEquals(driver.getTitle(), "Home page");
driver.findElement(By.xpath("//nav[@id='nav']//a[.='Mobile']")).click();
Assert.assertEquals(driver.getTitle(), "Mobile");
sortBy("Name");
System.out.println(getProductNames());
System.out.println(isListSorted(getProductNames()));

getProductNames()返回
