如何用Selenium 向CodeMirror 编辑器输入

用Selenium 自动填写Jenkins上面一个文本输入框，通过css定位很容易，但是输入文字的时候会报错

ElementNotVisibleException: Message: Element is not currently visible and so may not be interacted with

后来发现这个textarea 用CodeMirror了， google 结果如下

css_panel = driver.find_element_by_id("panel_css")

code_mirror_element = css_panel.find_element_by_css_selector(".CodeMirror")
driver.execute_script("arguments[0].CodeMirror.setValue(arguments[1]);",
                      code_mirror_element,
                      "test")
