Python selenium - 多处理 - 如何关闭已分配进程的浏览器？

Question

I know you can use driver.quit() and driver.close() but how to close nicely when executed multiple processes?

IDEAS:

• Use process ID?

Answer 1

Using Selenium to end the WebDriver and Web Browser session graciously you should invoke the quit() method within the tearDown() {} . Invoking quit() deletes the current browsing session through sending quit command with {"flags":["eForceQuit"]} and finally sends the GET request on /shutdown endpoint. Here is the relevant log:

1503397488598   webdriver::server   DEBUG   -> DELETE /session/8e457516-3335-4d3b-9140-53fb52aa8b74 
1503397488607   geckodriver::marionette TRACE   -> 37:[0,4,"quit",{"flags":["eForceQuit"]}]
1503397488821   webdriver::server   DEBUG   -> GET /shutdown

So on invoking quit() method the Web Browser session and the WebDriver instance gets killed completely.
