Python faker 生成测试数据

pip install Faker

基本使用

python 复制代码

from faker import Faker

if __name__ == '__main__':
    fake = Faker()
    print(fake.name())
    print(fake.user_name())
    print(fake.phone_number())
    print(fake.address())
# 输出：
Jorge Campbell
grobbins
769.415.0562x2019
255 Brooks Parkways
Gibbshaven, MO 43247

默认是英文 en_US

怎么生成中文数据？

python 复制代码

fake = Faker('zh_CN')

多国语言数据

python 复制代码

fake=Faker(['it_IT', 'en_US', 'ja_JP','zh_CN'])

支持那些国家的语言？

python 复制代码

from faker.config import AVAILABLE_LOCALES

print(AVAILABLE_LOCALES)

# ['ar_AA', 'ar_AE', 'ar_BH', 'ar_EG', 'ar_JO', 'ar_PS', 'ar_SA', 'az_AZ', 'bg_BG', 'bn_BD', 'bs_BA', 'cs_CZ', 'da_DK', 'de', 'de_AT', 'de_CH', 'de_DE', 'dk_DK', 'el_CY', 'el_GR', 'en', 'en_AU', 'en_CA', 'en_GB', 'en_IE', 'en_IN', 'en_NZ', 'en_PH', 'en_TH', 'en_US', 'es', 'es_AR', 'es_CA', 'es_CL', 'es_CO', 'es_ES', 'es_MX', 'et_EE', 'fa_IR', 'fi_FI', 'fil_PH', 'fr_BE', 'fr_CA', 'fr_CH', 'fr_FR', 'fr_QC', 'ga_IE', 'he_IL', 'hi_IN', 'hr_HR', 'hu_HU', 'hy_AM', 'id_ID', 'it_CH', 'it_IT', 'ja_JP', 'ka_GE', 'ko_KR', 'la', 'lb_LU', 'lt_LT', 'lv_LV', 'mt_MT', 'ne_NP', 'nl_BE', 'nl_NL', 'no_NO', 'or_IN', 'pl_PL', 'pt_BR', 'pt_PT', 'ro_RO', 'ru_RU', 'sk_SK', 'sl_SI', 'sq_AL', 'sv_SE', 'ta_IN', 'th', 'th_TH', 'tl_PH', 'tr_TR', 'tw_GH', 'uk_UA', 'vi_VN', 'zh_CN', 'zh_TW', 'zu_ZA']

支持生成那些数据？

python 复制代码

from faker import Faker

if __name__ == '__main__':
    fake = Faker()
    for data in dir(fake):
        if data.startswith('_'):
            continue
        print(data, end=', ')

自定义假数据

方法一：

python 复制代码

from random import choice
from faker import Faker
from faker.providers import BaseProvider


class MyProvider(BaseProvider):
    def my_fack_data(self) -> str:
        samples = ['自定义数据1', '自定义数据2']
        return choice(samples)


if __name__ == '__main__':
    fake = Faker()
    fake.add_provider(MyProvider)
    print(fake.my_fack_data())

方法二：

python 复制代码

from faker import Faker
from faker.providers import DynamicProvider

medical_professions_provider = DynamicProvider(
    provider_name="medical_profession",
    elements=["dr.", "doctor", "nurse", "surgeon", "clerk"],
)

if __name__ == '__main__':
    fake = Faker()
    fake.add_provider(medical_professions_provider)

    print(fake.medical_profession())
