我正在使用python-selenium来运行自动化测试。在复杂的非公开环境中，这些测试正在运行中，我发现了一些我将其标记为硒中的错误的东西。
基本上，我想做的是在DOM中变得可单击时在其中找到一些元素，然后单击它。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，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 ！我假设EC.element_to_be_clickable就是这个意思。但事实并非如此。那是硒中的错误吗？
解决方法是以下代码：
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)
这对我来说不太好。有没有办法改善代码？硒中有虫子吗？如果是这样，我可以举报...

答案 0 :(得分：3)
由于ElementToBeClickable正在等待元素被启用而失败的原因，它并不是在真正检查元素是否可点击，而是假设元素被启用时假设元素是可点击的，实际上是正确的，但是在这里失败了，因为即使另一个元素叠加在所需元素上，元素也会启用。
所以请编写此代码以使覆盖消失
WebDriverWait(bspdriver.webdriver,10).until(EC.invisibility_of_element_located((By.XPATH, "//div[@class='ivu-modal-wrap vertical-center-modal circuit-loading-modal']")));
然后您编写代码
what = (By.XPATH, '//button/span[contains(text(), "Load")]')
element = WebDriverWait(bspdriver.webdriver, 60).\
until(EC.element_to_be_clickable(what))
element.click()
如果覆盖层是临时的，则上述解决方案将起作用；如果覆盖层是永久的，则执行Javascript单击，因为WebDriver内部检查将阻止您进行单击。
