Python读取配置文件

使用Python做自动化时，需要将相关的信息存储在配置文件中，比如config.ini的文件，如何才能将存储在配置文件的数据读取出来呢？

config.ini文件内容如下：

[driver]
chromedriver = E:\automation\UI\Testcase\browser\chromedriver.exe
[homepage]
url = https://www.sougou.com/
[signup]
name = E:\automation\UI\Testdata\signup-data.csv
[login]
name = E:\automation\UI\Testdata\login-data.csv
[sign_user]
name = E:\automation\UI\Testdata\sign_user.csv
[sign_mobile]
name = E:\automation\UI\Testdata\sign_mobile.csv
[sign_pwd]
name = E:\automation\UI\Testdata\sign_pwd.csv
[vip_user]
name = E:\automation\UI\Testdata\vip_user.csv
[serach]
name = E:\automation\UI\Testdata\search.csv
[DATABASE]
host = 10.0.0.1
username = TEST
password = test
dbname = Test
[HEADERS]
contentType = application/x-www-form-urlencoded
[HTTP]
url = https://baidu.com
login = https://github.com

configparser读取配置信息并实例化
可以将要访问的url地址、读取的数据文件路径、数据库信息等写入配置文件，然后利用configparser模块读取，然后实例化，示例代码如下：
readConfig.py

# coding=utf-8
import os
from configparser import ConfigParser

# 获取绝对路径
BASE_DIR = os.path.dirname(__file__)
CONFIG_FILE_PATH = os.path.join(BASE_DIR, "config.ini") # 配置文件名称

class MyConfig:
def __init__(self):

config = ConfigParser()
config.read(CONFIG_FILE_PATH)

self.browerDriver = config.get("driver", "chromedriver") # 浏览器驱动
self.homedoUrl = config.get("homepage", "url") # 搜狗url
self.signupData = config.get("signup","name") # 用户注册测试数据
self.loginData = config.get("login","name") # 用户登录测试数据
self.signUser = config.get("sign_user","name") # 注册用户数据
self.signMobile = config.get("sign_mobile","name") # 注册用户手机号码
self.signPwd = config.get("sign_pwd","name") # 注册用户密码
self.vipUser = config.get("vip_user","name") # 生产白名单测试账号
self.search = config.get("serach","name") # 搜索数据
self.contentType = config.get("HEADERS", "contentType") # 请求头连接类型
self.URL = config.get("HTTP", "url") # 百度URL
self.loginURL =config.get("HTTP", "login") # github的URL

myconfig = MyConfig()

 

调用实例化的配置信息

将我们需要的信息实例化后封装，在需要的时候，直接调用即可，示例代码（测试手机验证码）如下：

test_mobcode.py

# coding=utf-8
from selenium import webdriver
from readConfig import myconfig
from selenium.webdriver.common.by import By
import unittest,time

class MobCodeTest(unittest.TestCase):
def setUp(self):
self.driver = webdriver.Chrome(myconfig.browerDriver) # 调用实例化后的浏览器驱动
self.driver.maximize_window()
self.url = myconfig.homedoUrl # 调用实例化后的请求url

def test_mobcode(self):
driver = self.driver
driver.get(self.url)
driver.implicitly_wait(3)
driver.find_element_by_link_text("免费注册").click()
driver.find_element_by_id("txtMobileCode").send_keys("1234")
driver.find_element_by_class_name("login-btn").click()

# 定位报错提示元素并断言，打印出来
error = driver.find_element_by_xpath("//*[@id=\"loginForm\"]/div/dl[2]/dd/p")
print(error.text)
self.assertIsNotNone(error.text)

def tearDown(self):
self.driver.close()

suite = unittest.TestSuite()
suite.addTest(MobCodeTest("test_mobcode"))
runner = unittest.TextTestRunner()
runner.run(suite)
