从单元测试读取配置文件

import json

def read_config(file_path):
    with open(file_path, 'r') as file:
        config = json.load(file)
    return config

# 示例配置文件 config.json
# {
#     "database": {
#         "host": "localhost",
#         "port": 5432,
#         "name": "mydb"
#     },
#     "logging": {
#         "level": "INFO"
#     }
# }

config = read_config('config.json')
print(config['database']['host'])  # 输出: localhost
