Python3+unittest+request 实现接口自动化测试 (完整简单案例)
前言
小白个人研究成果,仅供参考
一、准备工作
1. 建好项目及相关文件夹
- common - 通用类,用于存放所有可以共用的类,例如写入日志、连接数据库,连接接口等
- result - 用于存放所有结果,例如生成的日志文件以及生成的html测试报告
- testCase - 存放所有测试用例
- testFile - 存放相关文档
- 没有存放在文件夹里面的还有
caselist.txt - 存放所有要执行的用例的路径 config.ini - 配置文件 readConfig.py - 读取配置文件config.ini runAll.py - 测试入口
2. 准备好相关文档
testFile 文件夹下:
- case_demo.xls 用于存放所有要执行测试用例路径(这个可以后面写,但先讲)
内容如下: 包含 case_name:用例名称、method:请求方式,url:接口路径,params:参数,code:响应码, meaasge:响应内容 - sql.xml 存放所有要执行的sql
<page>
<database name="db_demo_org">
<table name="t_organization_info">
<sql id="selectByCity">SELECT * FROM t_organization_info WHERE city = %s</sql>
<sql id="selectByTypeAndCity">SELECT * FROM t_organization_info WHERE org_code_type = %s and city = %s</sql>
</table>
</database>
<database name="demo">
<table name="t_case">
<sql id="selectCaseAll">SELECT * FROM t_case</sql>
</table>
</database>
</page>
最外层文件: caselist.txt 存放要执行的测试用例路径 config.ini 存放配置文件,例如数据库配置、邮箱配置、http请求配置等 email 参数讲解: code:是邮件授权码(不是密码哦,具体参考https://baijiahao.baidu.com/s?id=1552315463915496&wfr=spider&for=pc) smpt:是邮箱服务器地址,我用的是qq邮箱 sender:发送者 recerives :接收者,可以写多个 subject :邮件标题
[DATABASE]
host = 127.0.0.1
port = 3306
name = root
pwd = 123456
database = db_demo_org
[DATABASE_CASE]
host = 127.0.0.1
port = 3306
name = root
pwd = 123456
database = demo
[HTTP]
url = http:
timeout = 3
[EMAIL]
smtp = smtp.qq.com
sender = 145xxxxxx@qq.com
recerives = 227xxxxx0@qq.com
code = xxxxxxxxxqxoifaa
subject = 接口自动化测试报告
content = 您好,附件是接口自动化测试报告,请查收。
on_off = 1
二、代码部分
1. readConfig.py读取config.ini配置文件
创建readConfig.py
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import os
import codecs
import configparser
# 获取当前py文件路径的上一层
localDir = os.path.split(os.path.realpath(__file__))[0]
# 拼接成config.ini完整路径
configPath = os.path.join(localDir, 'config.ini')
class ReadConfig:
"""读取config.ini文件"""
def __init__(self):
# 打开文件
config_file = open(configPath, encoding='UTF-8')
data = config_file.read()
# 判断是否带BOM文件
if data[:3] == codecs.BOM_UTF8:
data = data[3:]
file = codecs.open(configPath, 'w', encoding='UTF-8')
# 改写文件
file.write(data)
file.close()
config_file.close()
# 创建configparser实例
self.cf = configparser.ConfigParser()
# 读取配置文件
self.cf.read(configPath, encoding='UTF-8')
# 获取配置文件email的参数
def get_email(self, name):
return self.cf.get('EMAIL', name)
# 获取配置文件http的参数
def get_http(self, name):
return self.cf.get('HTTP', name)
# 获取配置文件database的参数
def get_database(self, name):
return self.cf.get('DATABASE', name)
# 获取配置文件database_case的参数
def get_database_case(self, name):
return self.cf.get('DATABASE_CASE', name)
2. 创建公用类
common文件夹下(以下几个py文件我就不分先后顺序介绍了):
- configDB.py 操作数据库
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import MySQLdb # python3安装命令:pip3 install Mysqlclien
from readConfig import ReadConfig
from common.myLog import MyLog
myConfig = ReadConfig()
class MyDB:
"""数据库"""
global host, name, pwd, port, database, config
# 获取配置文件中的参数
host = myConfig.get_database("host")
name = myConfig.get_database("name")
pwd = myConfig.get_database("pwd")
port = myConfig.get_database("port")
database = myConfig.get_database("database")
config = {
'host': str(host),
'user': name,
'password': pwd,
'port': int(port),
'db': database,
'charset': 'utf8'
}
def __init__(self):
self.logger = MyLog.get_log().logger
self.db = None
self.cursor = None
def connect_db(self):
"""连接数据库"""
try:
self.db = MySQLdb.connect(**config)
self.cursor = self.db.cursor()
print('数据库已连接成功')
except ConnectionError as e:
self.logger.error(str(e))
def execute_sql(self, sql, params):
"""执行sql并返回操作游标"""
try:
self.connect_db()
self.cursor.execute(sql, params)
self.db.commit()
return self.cursor
except RuntimeError as e:
self.db.rollback()
def get_all(self, cursor):
"""获取全部数据"""
value = cursor.fetchall()
return value
def get_one(self, cursor):
"""获取第一条数据"""
value = cursor.fetchone()
return value
def close_db(self):
"""关闭数据库"""
self.db.close()
print('数据库已关闭')
- configDBCase.py 还是操作数据库,但我这里是另一个数据库专门处理测试用例的(本文读取测试用例一共用了两种方式 1-读取数据库,2-读取xls文档)
#!/usr/bin/env python
# -*- coding:utf-8 -*-

port = myConfig.get_database_case("port")
database = myConfig.get_database_case("database")
config = {
'host': str(host),
'user': name,
'password': pwd,
'port': int(port),

}
def __init__(self):

self.logger = MyLog.get_log().logger
self.db = None
self.cursor = None

try:
self.db = MySQLdb.connect(**config)
self.cursor = self.db.cursor()
print('数据库已连接成功')
except ConnectionError as e:
self.logger.error(str(e))
def execute_sql(self, sql, params):
"""执行sql并返回操作游标"""
try:
self.connect_db()
self.cursor.execute(sql, params)
self.db.commit()
return self.cursor
except RuntimeError as e:
self.db.rollback()
def get_all(self, cursor):
"""返回全部数据"""
value = cursor.fetchall()
return value

return value
def close_db(self):

- configEmail.py 处理邮件

- configHttp.py 请求接口
