我用来python-selenium运行自动化测试。在复杂的非公共环境中运行这些测试时，我发现了一些我将标记为 selenium 中的错误的东西。
基本上我想做的是在 DOM 中找到一些元素，当它变得可点击时，然后点击它。代码如下：
....
what = (By.XPATH, '//button/span[contains(text(), "Load")]')
element = WebDriverWait(bspdriver.webdriver, 60).\
until(EC.element_to_be_clickable(what))
element.click()
....
但是，该click方法几乎立即失败，并显示以下错误消息：
ElementClickInterceptedException: Message: Element <button class="ivu-btn ivu-btn-primary ivu-btn-long ivu-btn-small" type="button"> is not clickable at point (1193.3332901000977,522) because another element <div class="ivu-modal-wrap vertical-center-modal circuit-loading-modal"> obscures it
我虽然正在等待该元素可点击！我以为这EC.element_to_be_clickable就是这个意思。但事实并非如此。这是硒中的错误吗？
解决方法是使用以下代码：
mustend = time.time() + 60
while time.time() < mustend:
try:
WebDriverWait(bspdriver.webdriver, 60).\
until(EC.element_to_be_clickable(what)).click()
break
except (TimeoutException, NoSuchElementException,
StaleElementReferenceException,
ElementClickInterceptedException) as e:
time.sleep(1.0)
这对我来说看起来不太好。有没有办法改进代码？硒有缺陷吗？如果是的话我可以举报...
使用过的包：

它失败的原因ElementToBeClickable是等待元素被启用，它并没有真正检查该元素是否可点击，它假设如果元素被启用，则该元素是可点击的，实际上这是真的，但它在这里失败，因为即使另一个元素被启用，元素也被启用覆盖所需的元素。
所以写这段代码让覆盖层消失
WebDriverWait(bspdriver.webdriver,10).until(EC.invisibility_of_element_located((By.XPATH, "//div[@class='ivu-modal-wrap vertical-center-modal circuit-loading-modal']")));
然后你写你的代码
what = (By.XPATH, '//button/span[contains(text(), "Load")]')
element = WebDriverWait(bspdriver.webdriver, 60).\
until(EC.element_to_be_clickable(what))
element.click()
如果覆盖是临时的，则上述解决方案将起作用，如果它是永久的，则执行 Javascript 单击，因为 WebDriver 内部检查会阻止您执行单击。
