Java .click（）在Selenium webdriver中不一致

我有一个网站，有一个旋转木马与3个按钮为3旋转项目。这方面的html代码如下所示

<ul class="slick-dots" style="display: block;">
<li class="slick-active" aria-hidden="false">
<button type="button" data-role="none" role="button" tabindex="0">1</button>
</li>
<li aria-hidden="true">
<button type="button" data-role="none" role="button" tabindex="0">2</button>
</li>
<li aria-hidden="true">
<button type="button" data-role="none" role="button" tabindex="0">3</button>
</li>
</ul>

<ul class="slick-dots" style="display: block;">
<li class="" aria-hidden="true">
<button type="button" data-role="none" role="button" tabindex="0">1</button>
</li>
<li class="slick-active" aria-hidden="false">
<button type="button" data-role="none" role="button" tabindex="0" 
style="">2</button>
</li>
<li aria-hidden="true">
<button type="button" data-role="none" role="button" tabindex="0">3</button>
</li>
</ul>

加载站点时，将启用第一个按钮。 单击旋转木马中的第二个按钮，将更改html，如下所示：

<ul class="slick-dots" style="display: block;">
<li class="slick-active" aria-hidden="false">
<button type="button" data-role="none" role="button" tabindex="0">1</button>
</li>
<li aria-hidden="true">
<button type="button" data-role="none" role="button" tabindex="0">2</button>
</li>
<li aria-hidden="true">
<button type="button" data-role="none" role="button" tabindex="0">3</button>
</li>
</ul>

<ul class="slick-dots" style="display: block;">
<li class="" aria-hidden="true">
<button type="button" data-role="none" role="button" tabindex="0">1</button>
</li>
<li class="slick-active" aria-hidden="false">
<button type="button" data-role="none" role="button" tabindex="0" 
style="">2</button>
</li>
<li aria-hidden="true">
<button type="button" data-role="none" role="button" tabindex="0">3</button>
</li>
</ul>

我需要单击每个旋转木马按钮并捕获相应的标题。以下是我到目前为止所做的。然而，这并不总是有效的。但是，如果我调试代码，那么所有3个标题都被正确捕获

    int CarouselItem=2;
    for (int i = 1; i<=CarouselItems.size(); i++) {

        driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
        //*getting the page header heading
           WebElement PageHeaderHeading = driver.findElement(By.xpath("//div[1]/main/section/div/div/div/div[" + i + "]/div[2]/div/div/div[2]/h1"));
            System.out.println("Page header text of "+i+" now is " + PageHeaderHeading.getText());

         //* clicking on the 2nd and 3rd carousel buttons   
        if(CarouselItem<=CarouselItems.size())
        {
            WebElement CarouselButtonToClick = driver.findElement(By.xpath("//li[(@aria-hidden='true') and button[contains(text(),'"+CarouselItem+"')]]"));
           driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);

            CarouselButtonToClick.click();
            CarouselItem = CarouselItem + 1;
        }
    }

int CarouselItem=2；
for（int i=1；我的意思是，您需要根据“调试时，它可以工作”显式等待页面加载。请检查。@VinceEmigh，非常感谢！显式等待对我很有效：）
