ruby - 使用 Capybara 附加文件 - 元素当前不可见并且 > 因此可能无法与之交互

Question

我正在尝试使用 Capybara 附加文件。输入元素是:

<input type="file" multiple="multiple" name="uploadfile[]" style="position: absolute; margin: 0px 0px 0px -175px; padding: 0px; width: 220px; height: 30px; font-size: 14px; opacity: 0; cursor: pointer; display: block; z-index: 2147483583; top: 3331px; left: 436px;">

附加文件的代码是:

attach_file 'uploadfile[]', '/home/user/image.jpg'

但它返回错误:

如何解决这个问题？

Answer 1

attach_file('locator', 'path/to/file.jpg', :visible => false )

应该可以解决问题。 capybara 默认忽略隐藏字段，你需要做的就是传入一个可见性选项
