Capture Page Screenshot
Arguments:[ filename=None ]
Takes a screenshot of the current page and embeds it into the log.
`filename` argument specifies the name of the file to write the screenshot into. If no `filename` is given, the screenshot is saved into file `selenium-screenshot-<counter>.png` under the directory where the Robot Framework log file is written into. The `filename` is also considered relative to the same directory, if it is not given in absolute format.
`css` can be used to modify how the screenshot is taken. By default the bakground color is changed to avoid possible problems with background leaking when the page layout is somehow broken.

说明：捕捉网页截图。可为截图命名或使用默认名（selenium-screenshot-<counter>）在指定截图保存目录下。

例子：Capture Page Screenshot | 截图20160925001

Choose File
Arguments:[ locator | file_path ]
Inputs the `file_path` into file input field found by `identifier`.
This keyword is most often used to input files into upload forms. The file specified with `file_path` must be available on the same host where the Selenium Server is running.

说明：选择文件。在上传页面，直接使用该关键字。或与关键字（get file）组合使用。

例子：

choose file | xpath=//div[@class=‘pd6 dot fcb‘]/span/input | C:\\Documents and Settings\\xxx\\My Documents\\My Pictures\\bug5.png

choose file | get file | C:\\Documents and Settings\\xxx\\My Documents\\My Pictures\\bug5.png

Choose Ok On Next Confirmation
Arguments:[ ]
Undo the effect of using keywords `Choose Cancel On Next Confirmation`. Note that Selenium‘s overridden window.confirm() function will normally automatically return true, as if the user had manually clicked OK, so you shouldn‘t need to use this command unless for some reason you need to change your mind prior to the next confirmation. After any confirmation, Selenium will resume using the default behavior for future confirmations, automatically returning true (OK) unless/until you explicitly use `Choose Cancel On Next Confirmation` for each confirmation.
Note that every time a confirmation comes up, you must consume it by using a keywords such as `Get Alert Message`, or else the following selenium operations will fail.

说明：在含“确定/取消”的弹出框中选择“确定”。

例子：Choose Ok On Next Confirmation
