python搭建微信小程序
微信官方發(fā)布小程序自動化測試框架Minium。該框架支持使用Python或者Javascript編寫自動化測試程序,可以運行在IDE、Android以及iOS三端。
由于是微信官方發(fā)布,該框架注定秒殺現(xiàn)有一切第三方自動化測試框架。該框架支持多種內核運行(X5\原生Webview)以模擬小程序的實際使用場景;可以直接觸發(fā)小程序上的事件,甚至可以直接調用部分wx.開頭的接口;支持直接向AppService注入代碼。
查看文檔仍需配置nodejs環(huán)境,這一點對Python程序員來說還不夠友好。實際上使用該框架并不需要nodejs環(huán)境,依舊是Python程序員們熟悉的pip install ... 但是不知為何該項目文檔要求運行nodejs環(huán)境才能查看。為此,我們把項目文檔上傳到了github,以便Python程序員可以不必安裝nodejs,直接查看項目文檔。
