unlocking process? So how do we translate the above process into code? See below:Touchaction (Self.driver). Press (). Move_to (). Move_to (). Release (). Perfrom ()This is the code for our entire process, but what if you do it in a positive way? Because I do not know what you want, from where to move to, can not error?First the press () needs to specify an object, right. So here's a look at the press () syntax:Press (Webelement e): Here you need to pass in a webelement element, but as the pictu

attention to the existence of small size mobile phone screen, now most of the smartphone resolution is 640*960px (iphone4 resolution) above, so long as the important content on the blind spot, The calculated maximum security height is 812 (960-148=812).In this summary, in general, to the existing market on the popular mobile smartphones, single-page rollover (non-extended down the long page) design size of
