How to use Faker to Test data in batch based on Python

This article mainly introduces based on Python how to use Faker batch test data related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe you will have something to gain after reading this article on how to use Faker batch test data based on Python, let's take a look.

In the process of testing, it is often necessary to create data in batches, and there are many methods, the most simple and convenient one should be to use Faker, a third-party library of python.

Script function, batch generate 10000 pieces of basic data, write to the local file: test_data.csv

Execute on the linux server, take the test_data.csv to the local windows,excel and open the possible Chinese garbled code. You can use: data-Import data from text / CSV, modify the encoding format, and display Chinese normally.

File.close ()
