python如何使用unittest测试接口

本文实例为大家分享了python使用unittest 测试接口的具体代码，供大家参考，具体内容如下

1.首先使用 python 的requests 对接口进行测试

# TestInface.py
import requests,json
url = visit.get_test_url()
news_url = url+'news.info'
headers = baseToken.basetoken_datas()['headers']
def new_data(data): 

  r = requests.post(news_url,data=data,headers=headers)
  cnn = json.loads(r.text)
  return cnn 

2.使用unittest调用接口，且对接口测试的结果进行统计

# TestCase.py
# -*- coding:utf-8 -*-
import unittest
import TestInface 

# 对执行的case结果进行统计
# ---------------------------------------------------------------------------------------------------------------------
text = ""
num_success = 0
num_fail = 0 

# 测试通过
def decide_success(joggle):
  global num_success
  num_success += 1
  print_out(joggle + ":接口测试通过\n")
  return num_success 

# 测试不通过
def decide_fail(txt, joggle):
  global num_fail
  num_fail += 1
  print_out(joggle + ":接口测试未通过 \n错误信息： " + txt + "\n")
  return num_fail 

# 邮件内容写入 & 客户端输出
def print_out(message):
  global text
  text += "\n" + message
  return text 

# 返回值判断
def decide_result(result, code, joggle):
  if result['code'] == code:
    decide_success(joggle)
    return "pass"
  else:
    txt = u"期望返回值:" + str(code) + u" 实际返回值:" + str(result) + '\n' + result['message']
    decide_fail(txt, joggle)
    return "fail" 

def decide_Count():
  data = {
    'num_success': num_success,
    'num_fail': num_fail,
    'text': text
  }
  return data
# --------------------------------------------------------------------------------------------------------------------
# 定义 unittest
class MyTestCase(unittest.TestCase):  

  # 初始化工作
  def setUp(self):
    pass  

  # 退出清理工作
  def tearDown(self):
    pass
  def test_Case1(self):
  id = 16
    data = {'id':id}
    a = TestInface.new_data(data)
    decide_result(a,0,'test_Case1') 

3.使用suite对case进行管理

# TestSuite.py
# -*- coding:utf-8 -*-
import unittest
import TestCase 

def test_InterFace(): 

  # 构造测试集
  suite = unittest.TestSuite()
  suite.addTest(TestCase("test_Case1")) # unittest中的测试用例 

  runner = unittest.TextTestRunner()
  runner.run(suite)
  #　对测试集进行测试需要返回值
  # return suite 

if __name__ == '__main__': 

  # unittest.main(defaultTest='test_InterFace')
  # 执行测试
  runner = unittest.TextTestRunner()
  runner.run(test_InterFace())

4.对接口的数据进行统计

# TestCensus.py
# -*- coding:utf-8 -*-
import time
import TestSuite
import send_email
import TestCase 

class Test_Calss(): 

  def census(self):
    text = ''
    # 初始化测试起始时间
    start_time = time.time()
    # 调用suite测试集
    TestSuite.test_InterFace()
    # 结束执行时间计算
    end_time = time.time() 

    result = TestCase.decide_Count()
    # 接口测试统计说明
    total_use_case = u"执行用例总数:" + str(result['num_success'] + result['num_fail']) + \
             u"\t通过数:" + str(result['num_success']) + \
             u"\t不通过数:" + str(result['num_fail'])
    total_time = u"\t总共耗时：" + str(round((end_time - start_time), 3)) + u'秒'
    text = result['text'] + total_use_case + total_time
    print (text) 

    # 发生测试报告邮件
    send_email.email_file(text) 

if __name__ == '__main__':
  Test_Calss().census()
