在几次GUI操作后尝试验证一些按钮不存在(预期不存在).我正在使用find_element_by_xpath()，但是它非常慢.有什么办法解决超时问题吗?

Trying to verify after few GUI operations some button does not exist (expected not to be present). I am using find_element_by_xpath() but its very slow. Any solution of timeout?

推荐答案

实际上，如果找不到指定的元素，WebDriver的find_element方法将等待元素的隐式时间.

Actually WebDriver's find_element method will wait for implicit time for the element if the specified element is not found.

WebDriver中没有可检查的预定义方法，例如isElementPresent().您应该为此编写自己的逻辑.

There is no predefined method in WebDriver like isElementPresent() to check. You should write your own logic for that.

逻辑

public boolean isElementPresent() { try { set_the_implicit time to zero find_element_by_xpath() set_the_implicit time to your default time (say 30 sec) return true; } catch(Exception e) { return false; } }
