java - Selenium Java - 检查 Weblist 元素是否存在

Question

我需要自动化一个场景，我需要单击“全部展开”按钮并检查所有过滤器是否已展开，然后单击“全部折叠”按钮并检查是否所有过滤器均已折叠。

我使用的方法是将所有过滤器放入网络列表中，获取其大小，然后使用断言方法检查其是否为非空，但对于检查折叠功能，相同的方法失败了。

是否有一种方法可以检查 WebElements 列表的可见性或存在性，就像我们对单个 WebElement 使用 isDisplayed() 一样？

下面是我尝试过的上述逻辑的代码:

driver.findElement(By.linkText("Expand All")).click();
Thread.sleep(3000);
System.out.println("Clicking on the Expand All option");

Assert.assertFalse(driver.findElements(By.cssSelector("input[type='checkbox']")).isEmpty(),"The Filters are not expanded"); 

int filters_max_size=driver.findElements(By.cssSelector("input[type='checkbox']")).size();

System.out.println("There are total "+filters_max_size+ "filters expanded");

System.out.println("Clicking on the Collapse All option");
Reporter.log("Clicking on the Collapse All option");

driver.findElement(By.id("collapse_all")).click();
Thread.sleep(3000);

Assert.assertTrue(driver.findElements(By.cssSelector("input[type='checkbox']")).isEmpty(),"The Filters are not collapsed"); 
Assert.assertEquals(0, driver.findElements(By.cssSelector("input[type='checkbox']")).,"The Filters are not collapsed");


<a class="refinement_anchor" href="/search?button=search&expand_all=5B%5D=%7B%22s%22%3A%5B%7B%22id%22%3A%22%22%2C%22xPath%22%3A%22%24source_type%22%2C%22logic%22%3A%22OR%22%2C&utf8=%E2%9C%93">
<input id="refinement_214391870" class="flex" type="checkbox" name="refinement_214391870">
<label class="text" for="refinement_214391870">
<div class="text refinement_information">

</div>
</label>
</a>
</li>
<li class="text no_children ">
</ul>
<a class="show_all" href="/search/show_all?button=search&id=&q=&types=&utf8=%E2%9C%93&widget_id=refine_source_type">Show all</a>
</div>

Answer 1

您可以尝试如下:

 driver.findElement(By.id("collapse_all")).click();
 Thread.sleep(3000);

WebElement allFilters = driver.findElements(By.cssSelector("input[type='checkbox']"));
for(WebElement filter : allFilters) {

 if(filter.isDisplayed()){

   System.out.println(filter.getText() + " is still displayed." );
   break;
 }}
