Millisecond upload batch attachments

This article tells ： During the test , Upload batch attachments in milliseconds through automated scripts .

Be careful ： This article requires you to have the following skills

• Test the basics
• python Programming knowledge
• Database knowledge
• Automation framework idea

During the test , Statistics show that all forms and pages of the tested system share 39 Attachments （ picture ） Need to upload ; Here's how it works ：

• 1、 Form page , Click on “ Upload ” Button , Select the locally prepared attachment in the pop-up window （ picture ）, In the case of skilled operation, it costs about 2 second ;
• 2、39 Zhang *2 second / Zhang =72 second
• 3、 During the test , Test data that needs to be constructed every day , It's about 30 strip
• 4、 hold 2 and 3 Multiplication is 72 second / strip *30 strip =2160 second , Reduced contract 36 minute , That is, just uploading attachments consumes me 36 minute ;

that , The problem is coming. “ I was angry …”

I try to upload attachments automatically , The result really surprised ;

“ A total of 39 Attachments , It took time 0.12213140000000003 second ”, notice pycharm Messages printed from the console , The author is very happy .

[2088-08-8 8:8:8] - INFO:  It takes time to connect to the database 0.002419699999999997 second 
......
[2088-08-8 8:8:9] - INFO:  A total of 39 Attachments , It took time 0.12213140000000003 second .

In that case ,39 Zhang *0.122 second / Zhang =4.758 second ;
It seems , The speed of automation is about manual 454 times ;

that , How did the author achieve it ？
Don't worry , Stand firm and hold it well , Now let's roll up ！
