前言

1.环境准备:api

  • python3.6
  • requests
  • xlrd
  • openpyxl
  • HTMLTestRunner_api

2.目前实现的功能:cookie

  • 封装requests请求方法
  • 在excel填写接口请求参数
  • 运行完后,从新生成一个excel报告,结果写入excel
  • 用unittest+ddt数据驱动模式执行
  • HTMLTestRunner生成可视化的html报告
  • 对于没有关联的单个接口请求是能够批量执行的,须要登陆的话写到setUpclass里的session里保持cookies
  • token关联的不能实现
  • logging日志文件暂时未加入

3.目前已知的缺陷:session

  • 没法实现参数关联:上个请求的结果是下个请求的参数,如token
  • 接口请求参数名有重复的,目前未处理,如key1=value1&key1=value2,两个key都同样,这种须要用元组存储,目前暂时未判断
  • 生成的excel样式未处理,后期慢慢优化样式
  • python新手可能遇到模块导入报错问题

项目结构

excel测试数据

xlrd读excel数据

1.先从excel里面读取测试数据,返回字典格式app

# coding:utf-8

# 做者:上海-悠悠 # QQ群:226296743

import xlrd class ExcelUtil(): def __init__(self, excelPath, sheetName="Sheet1"): self.data = xlrd.open_workbook(excelPath) self.table = self.data.sheet_by_name(sheetName) # 获取第一行做为key值
        self.keys = self.table.row_values(0) # 获取总行数
        self.rowNum = self.table.nrows # 获取总列数
        self.colNum = self.table.ncols def dict_data(self): if self.rowNum <= 1: print("总行数小于1") else: r = [] j = 1
            for i in list(range(self.rowNum-1)): s = {} # 从第二行取对应values值
                s['rowNum'] = i+2 values = self.table.row_values(j) for x in list(range(self.colNum)): s[self.keys[x]] = values[x] r.append(s) j += 1
            return r if __name__ == "__main__": filepath = "debug_api.xlsx" sheetName = "Sheet1" data = ExcelUtil(filepath, sheetName) print(data.dict_data())

 

openpyxl写入数据

1.再封装一个写入excel数据的方法框架

# coding:utf-8
from openpyxl import load_workbook import openpyxl # 做者:上海-悠悠 # QQ群:226296743

def copy_excel(excelpath1, excelpath2): '''复制excek,把excelpath1数据复制到excelpath2''' wb2 = openpyxl.Workbook() wb2.save(excelpath2) # 读取数据
    wb1 = openpyxl.load_workbook(excelpath1) wb2 = openpyxl.load_workbook(excelpath2) sheets1 = wb1.sheetnames sheets2 = wb2.sheetnames sheet1 = wb1[sheets1[0]] sheet2 = wb2[sheets2[0]] max_row = sheet1.max_row         # 最大行数
    max_column = sheet1.max_column   # 最大列数

    for m in list(range(1,max_row+1)): for n in list(range(97,97+max_column)):   # chr(97)='a'
            n = chr(n)                            # ASCII字符
            i ='%s%d'% (n, m)                     # 单元格编号
            cell1 = sheet1[i].value               # 获取data单元格数据
            sheet2[i].value = cell1               # 赋值到test单元格
 wb2.save(excelpath2) # 保存数据
    wb1.close()                          # 关闭excel
 wb2.close() class Write_excel(object): '''修改excel数据'''
    def __init__(self, filename): self.filename = filename self.wb = load_workbook(self.filename) self.ws = self.wb.active  # 激活sheet

    def write(self, row_n, col_n, value): '''写入数据,如(2,3,"hello"),第二行第三列写入数据"hello"''' self.ws.cell(row_n, col_n).value = value self.wb.save(self.filename) if __name__ == "__main__": copy_excel("debug_api.xlsx", "testreport.xlsx") wt = Write_excel("testreport.xlsx") wt.write(4, 5, "HELLEOP") wt.write(4, 6, "HELLEOP")

 

封装request请求方法

1.把从excel读处理的数据做为请求参数,封装requests请求方法,传入请求参数,并返回结果

2.为了避免污染测试的数据,出报告的时候先将测试的excel复制都应该新的excel

3.把测试返回的结果,在新的excel里面写入数据

# coding:utf-8
import json import requests from excelddtdriver.common.readexcel import ExcelUtil from excelddtdriver.common.writeexcel import copy_excel, Write_excel # 做者:上海-悠悠 # QQ群:226296743


def send_requests(s, testdata): '''封装requests请求''' method = testdata["method"] url = testdata["url"] # url后面的params参数
    try: params = eval(testdata["params"]) except: params = None # 请求头部headers
    try: headers = eval(testdata["headers"]) print("请求头部:%s" % headers) except: headers = None # post请求body类型
    type = testdata["type"] test_nub = testdata['id'] print("*******正在执行用例:----- %s ----**********" % test_nub) print("请求方式:%s, 请求url:%s" % (method, url)) print("请求params:%s" % params) # post请求body内容
    try: bodydata = eval(testdata["body"]) except: bodydata = {} # 判断传data数据仍是json
    if type == "data": body = bodydata elif type == "json": body = json.dumps(bodydata) else: body = bodydata if method == "post": print("post请求body类型为:%s ,body内容为:%s" % (type, body)) verify = False res = {}   # 接受返回数据

    try: r = s.request(method=method, url=url, params=params, headers=headers, data=body, verify=verify ) print("页面返回信息:%s" % r.content.decode("utf-8")) res['id'] = testdata['id'] res['rowNum'] = testdata['rowNum'] res["statuscode"] = str(r.status_code)  # 状态码转成str
        res["text"] = r.content.decode("utf-8") res["times"] = str(r.elapsed.total_seconds())   # 接口请求时间转str
        if res["statuscode"] != "200": res["error"] = res["text"] else: res["error"] = "" res["msg"] = ""
        if testdata["checkpoint"] in res["text"]: res["result"] = "pass"
            print("用例测试结果: %s---->%s" % (test_nub, res["result"])) else: res["result"] = "fail"
        return res except Exception as msg: res["msg"] = str(msg) return res def wirte_result(result, filename="result.xlsx"): # 返回结果的行数row_nub
    row_nub = result['rowNum'] # 写入statuscode
    wt = Write_excel(filename) wt.write(row_nub, 8, result['statuscode'])       # 写入返回状态码statuscode,第8列
    wt.write(row_nub, 9, result['times'])            # 耗时
    wt.write(row_nub, 10, result['error'])            # 状态码非200时的返回信息
    wt.write(row_nub, 12, result['result'])           # 测试结果 pass 仍是fail
    wt.write(row_nub, 13, result['msg'])           # 抛异常

if __name__ == "__main__": data = ExcelUtil("debug_api.xlsx").dict_data() print(data[0]) s = requests.session() res = send_requests(s, data[0]) copy_excel("debug_api.xlsx", "result.xlsx") wirte_result(res, filename="result.xlsx")

 

测试用例unittest+ddt

1.测试用例用unittest框架组建,并用ddt数据驱动模式,批量执行用例

# coding:utf-8
import unittest import ddt import os import requests from excelddtdriver.common import base_api from excelddtdriver.common import readexcel from excelddtdriver.common import writeexcel # 做者:上海-悠悠 # QQ群:226296743

# 获取demo_api.xlsx路径
curpath = os.path.dirname(os.path.realpath(__file__)) testxlsx = os.path.join(curpath, "demo_api.xlsx") # 复制demo_api.xlsx文件到report下
report_path = os.path.join(os.path.dirname(curpath), "report") reportxlsx = os.path.join(report_path, "result.xlsx") testdata = readexcel.ExcelUtil(testxlsx).dict_data() @ddt.ddt class Test_api(unittest.TestCase): @classmethod def setUpClass(cls): cls.s = requests.session() # 若是有登陆的话,就在这里先登陆了
        writeexcel.copy_excel(testxlsx, reportxlsx) # 复制xlsx
 @ddt.data(*testdata) def test_api(self, data): # 先复制excel数据到report
        res = base_api.send_requests(self.s, data) base_api.wirte_result(res, filename=reportxlsx) # 检查点 checkpoint
        check = data["checkpoint"] print("检查点->:%s"%check) # 返回结果
        res_text = res["text"] print("返回实际结果->:%s"%res_text) # 断言
        self.assertTrue(check in res_text) if __name__ == "__main__": unittest.main()

 

生成报告

1.用HTMLTestRunner生成html报告,我这里改了下名称,改为了HTMLTestRunner_api.py
此文件跟selenium的报告是通用的,github可下载https://github.com/yoyoketang/selenium_report/tree/master/selenium_report

# coding=utf-8
import unittest import time from excelddtdriver.common import HTMLTestRunner_api import os # 做者:上海-悠悠 # QQ群:226296743
 curpath = os.path.dirname(os.path.realpath(__file__)) report_path = os.path.join(curpath, "report") if not os.path.exists(report_path): os.mkdir(report_path) case_path = os.path.join(curpath, "case") def add_case(casepath=case_path, rule="test*.py"): '''加载全部的测试用例'''
    # 定义discover方法的参数
    discover = unittest.defaultTestLoader.discover(casepath, pattern=rule,) return discover def run_case(all_case, reportpath=report_path): '''执行全部的用例, 并把结果写入测试报告''' htmlreport = reportpath+r"\result.html"
    print("测试报告生成地址:%s"% htmlreport) fp = open(htmlreport, "wb") runner = HTMLTestRunner_api.HTMLTestRunner(stream=fp, verbosity=2, title="测试报告", description="用例执行状况") # 调用add_case函数返回值
 runner.run(all_case) fp.close() if __name__ == "__main__": cases = add_case() run_case(cases)
