Alibaba P8 teaches you how to realize multithreading in automated testing? Hurry up and stop

process

A process is a dynamic execution of a program on a dataset , We write programs to describe what functions a process needs to perform and how to do it .

Threads

Thread footer lightweight process , He is a basic CPU execution unit , Is an implementation in process , Threads appear to reduce the trumpet of context switching , Improve the concurrency of the system .

Threads and processes

A thread can only belong to one process , And a process can have multiple threads .
But few thread resources are allocated to the process , All threads of the same process share all resources of the process .
CPU To threads , That is true. CPU Threads running on .

Application of multithreading principle

1、 Parallelism and concurrency

parallel ： Each thread is assigned to a separate core , Thread running at the same time .

Concurrent ： Multiple threads running on a single core , One thread runs at a time , The system keeps switching threads , It looks like it's running at the same time , It's actually thread switching .

2、Python The multithreading

GIL Global timer lock ： If a thread wants to execute, it must first get GIL.

Python The multithreading ： In fact, only one thread can run at a time , But it can achieve concurrency .

3、Python Multithreaded applications

Different codes run differently , We can use multithreading , Form concurrent , Achieve improved efficiency .

Case study ：Web automation , Actually CPU After executing a command , Most of the time is waiting for , So this time ,CPU Will limit or do the tasks of other processes , So we can use multithreading , Realize multi browser automation and run at the same time , So as to achieve high efficiency .

The house needs to be built layer by layer , Knowledge needs to be learned at one point one . We should lay a good foundation in the process of learning , More hands-on practice , Don't talk much , The last dry goods here ！ I stayed up late to sort out the stages ( function 、 Interface 、 automation 、 performance 、 Test open ) Skills learning materials + Practical explanation , Very suitable for studying in private , It's much more efficient than self-study , Share with you .
