Selenium Java：Chrome中等待元素可点击断言失败问题排查

问题场景 #

编写Selenium测试时，针对亚马逊首页搜索栏旁的searchBoxDropdown下拉框，selectDropdownElement方法中用wdwait等待元素可点击的代码会报错，注释该等待逻辑后测试可正常通过。但同一测试里，数量下拉框用几乎相同的等待逻辑却能正常工作，两个下拉框均为Select类型。

相关代码 #

元素定位与初始方法实现 #

@FindBy(id="searchDropdownBox")
WebElement searchBoxDropdown;

public void selectDropdownElement(String elementx) {
    wdwait.until(ExpectedConditions.elementToBeClickable(searchBoxDropdown));
    Select elementDropdown = new Select(searchBoxDropdown);
    elementDropdown.selectByVisibleText(elementx);
}

测试用例 #

@Test
public void amazonTest() {
    amazonAddToCart.selectDropdownElement("Books");
    amazonAddToCart.inputSearchBox("Six of Crows Boxed Set");
    amazonAddToCart.clickBookLink();
    amazonAddToCart.selectHardcover();
    amazonAddToCart.selectQuantity(20);
    amazonAddToCart.clickGiftCheckbox();
    amazonAddToCart.clickAddToCart();
}

对应HTML元素 #

<select aria-describedby="searchDropdownDescription" class="nav-search-dropdown searchSelect nav-progressive-attrubute nav-progressive-search-dropdown" data-nav-digest="k+fyIAyB82R9jVEmroQ0OWwSW3A=" data-nav-selected="0" id="searchDropdownBox" name="url" style="display: block; top: 2.5px;" tabindex="0" title="Search in">

尝试过的无效方案 #

将elementToBeClickable替换为visibilityOfElements，报错情况依旧。

有效解决方法 #

改用textToBePresentInElement等待下拉框默认选项“All”加载完成，之后再执行选择操作：

public void selectDropdownElement(String elementx) {
    wdwait.until(ExpectedConditions.textToBePresentInElement(searchBoxDropdown, "All"));
    Select elementDropdown = new Select(searchBoxDropdown);
    elementDropdown.selectByVisibleText(elementx);
}
