python接口自动化unittest+HTMLrunner

1、创建一个packpage包

import unittest
import requests
from time import sleep
import HTMLTestRunner

# 构造WeatherTest类，继承unittest.TestCase
class WeatherTest(unittest.TestCase):
    # 用例执行前的准备工作
    def setUp(self):
        self.url = 'http://t.weather.sojson.com/api/weather/city'

    # 定义测试guangzhou天气的方法
    def test_weather_handan(self):   # 用例方法需要以test开头，便于执行顺利
        '''
        Case01-正常存在的city_code值
        '''
        data = {'city_code':'101091001'}
        r = requests.get(self.url+'/'+data['city_code'])    # 拼接接口URL
        result = r.json()   # 将返回结果转换为json类型

        # 设置断言
        self.assertEqual(result['status'],200)  # 状态码
        self.assertEqual(result['message'],'Success !')
        self.assertEqual(result['cityInfo']['city'],'邯郸市')
        self.assertEqual(result['cityInfo']['cityId'],'101091001')
        sleep(3)    # 控制请求的间隔时间，防止过快请求而IP受限制

    def test_weather_param_error(self):
        '''
        Case02-错误的city_code值
        '''
        data = {'city_code':'666abc'}

        self.assertEqual(result['message'],'Request resource not found.')
        self.assertEqual(result['status'],404)
        sleep(3)

# 调试WeatherTest类
