Multi threading in Selenium WebDriver

Question

I want to test a web application using multithreading in Selenium WebDrivre, but when I open too many chrome browsers the memory used is very large.

Is it possible to use multithreading in one browser using Selenium WebDriver?

Answer 1

WebDriver is not safe for multithreading. 

Thread-safety is not in the code but it is in the browser bindings. They assume that there will be only one command at a time but on the other hand, instantiate one WebDriver instance for every thread but it will launch multiple browsers which will again consume lots of memory.
