selenium +chrome headless Adhoc模式渲染网页
mannual和adhoc模式比较
Manual vs. Adhoc
In the script above, we start the ChromeDriver server process when we create the WebDriver object and it is terminated when we call quit(). For a one-off script, that isn’t a problem, but this can waste a nontrivial amount of time for a large test suite that creates a ChromeDriver instance for each test. Luckily, we can manually start and stop the server ourselves, and it only requires a few changes to the script above.
说的在使用selenium+chromeheadless做自动化测试时候,如果测试用例数量大,给每个测试用例启动一个浏览器要话费更多的时间。

反对极端面向过程编程思维方式,喜欢面向对象和设计模式的解读,喜欢对比极端面向过程编程和oop编程消耗代码代码行数的区别和原因。致力于使用oop和36种设计模式写出最高可复用的框架级代码和使用最少的代码行数完成任务,致力于使用oop和设计模式来使部分代码减少90%行,使绝大部分py文件最低减少50%-80%行的写法。
