用例是放在Excel中的，用xlrd来读取数据，写数据需要用到xluntils，先安装：
pip install xlrd
pip install xluntils
读取Excel数据，我们需要知道对应的行和列，列相对固定，在配置文件settings中定义，然后读取，行作为参数传入。conf/settings文件中的定义如下：
[excel]
case_no=0
case_name=1
is_run=2
case_level=3
case_header=4
case_cookies=5
req_type=6
case_url=7
case_body=8
expect_result=9
operator=10
actual_result=11
test_result=12在unitls/load_conf.py中编写读取配置的方法，获取各项列值的方法。lood_conf()函数需要传入两个参数：配置项字符串标识符，配置项类型。比如要读取excel下整数case_url：lood_conf("excel.case_url","int")。class excel_config()下定义返回各项列值的方法。
完整代码如下：
import configparser
‘‘‘
read conf from setting.conf
@:parameter:identstr,value_type
value_type:"int" or "str"
‘‘‘
def lood_conf(identstr,value_type):
cf = configparser.ConfigParser()
cf.read("../config/settings.conf")
idenlist = identstr.split(‘.‘)
if value_type == "int":
try:
value = cf.getint(idenlist[0],idenlist[1])
return value
except (configparser.NoSectionError ,configparser.NoOptionError) as e:
print(e)
if value_type == "str":
try:
value = cf.get(idenlist[0],idenlist[1])
return value
except (configparser.NoSectionError ,configparser.NoOptionError) as e:
print(e)
‘‘‘
获取url，request body等的列号
‘‘‘
class excel_config():
#获取用例编号的列
def caseno_col(self):
return lood_conf("excel.case_no","int")
def casename_col(self):
return lood_conf("excel.case_name","int")
def isrun_col(self):
#print(lood_conf("excel.is_run","int"))
return lood_conf("excel.is_run","int")
def level_col(self):
return lood_conf("excel.case_level","int")
def header_col(self):
return lood_conf("excel.case_header","int")
def cookies_col(self):
return lood_conf("excel.case_cookies","int")
def reqtype_col(self):
return lood_conf("excel.req_type","int")
def caseurl_col(self):
return lood_conf("excel.case_url","int")
def casebody_col(self):
return lood_conf("excel.case_body","int")
def expectresult_col(self):
return lood_conf("excel.expect_result","int")
def actualresult_col(self):
return lood_conf("excel.actual_result","int")
def testresult_col(self):
return lood_conf("excel.test_result","int")
def test_operator_col(self):
return lood_conf("excel.operator","int")
unitls/excel_tool.py中定义了获取用例编号，用例名称等方法，需要传入行。回写测试结果，回写实际结果方法需要传入两个参数：行，值。完整代码如下：
#coding:utf-8
import xlrd
from untils.log_trace import *
from xlutils.copy import copy
from untils.load_conf import excel_config
class excel_tool():
def __init__(self,excel_name):
self.curr_excel = xlrd.open_workbook(excel_name)
self.table = self.curr_excel.sheet_by_index(0)
#print(self.table.cell(1,1).value)
#实例化excel_config
self.config = excel_config()
self.rows = self.table.nrows
self.excel_name = excel_name
#获取用例编号
def get_caseno(self,row):
caseno = self.table.cell(row,self.config.caseno_col()).value
if caseno:
return caseno
else:
logging.info("case no is null")
return None
#获取用例名称
def get_casename(self,row):
casename = self.table.cell(row,self.config.casename_col()).value
return casename
#获取是否运行标志
def get_runflag(self,row):
run_flag = self.table.cell(row,self.config.isrun_col()).value
return run_flag
#获取用例级别
def get_caselevel(self,row):
caselevel = self.table.cell(row,self.config.level_col()).value
return caselevel
#获取请求url
def get_caseurl(self,row):
caseurl = self.table.cell(row,self.config.caseurl_col()).value
return caseurl
#获取请求body
def get_casebody(self,row):
case_body = self.table.cell(row,self.config.casebody_col()).value
return case_body
#获取header
def get_headerflag(self,row):
headerflag = self.table.cell(row,self.config.header_col()).value
return headerflag
#获取coocikes
def get_cookiesflag(self,row):
cookiesflag = self.table.cell(row,self.config.cookies_col()).value
return cookiesflag
#获取请求类型
def get_methodtype(self,row):
method_type = self.table.cell(row,self.config.reqtype_col()).value
return method_type
#获取预期结果
def get_expectres(self,row):
expect_res = self.table.cell(row,self.config.expectresult_col()).value
return expect_res
#获取测试结果
def get_testres(self,row):
test_res= self.table.cell(row,self.config.testresult_col()).value
return test_res
#获取操作符
def get_operator(self,row):
operator = self.table.cell(row,self.config.test_operator_col()).value
return operator
#回写测试结果到excel
def write_testres(self,row,value):
wbook = copy(xlrd.open_workbook(self.excel_name))
sheet = wbook.get_sheet(0)
sheet.write(row, self.config.testresult_col(), value)
wbook.save(self.excel_name)
#回写实际结果
def write_actualres(self,row,value):
wbook = copy(xlrd.open_workbook(self.excel_name))
sheet = wbook.get_sheet(0)
sheet.write(row, self.config.actualresult_col(), value)
wbook.save(self.excel_name)
有了Excel操作类，就可以方便读取数据和回填结果了。接下来，在unitls/run_main.py中来组装用例。组装之前，先获取是否运行的标志：
接口鉴权需要用到的headers，先在run_main.py 中写死，这个问题后面解决，在上面的过程中，增加必要的日志，方便定位问题和查看用例的运行日志。完整代码如下：
#coding:utf-8
from untils.excel_tool import excel_tool
from untils.send_request import send_request
from untils.log_trace import *
from untils.check_result import CheckResult
import json
headers = {
"X-Token":"0a6db4e59c7fff2b2b94a297e2e5632e"
}
class runner():
def __init__(self):
self.excel = excel_tool("../testcase/test.xls")
self.check = CheckResult()
def join_case(self):
global skip_list,sucess_list,failed_list,skip_list
sucess_list = []
sucess_list = []
failed_list = []
skip_list = []
for row in range(1,self.excel.rows):
no = self.excel.get_caseno(row)
url = self.excel.get_caseurl(row)
isrun = self.excel.get_runflag(row)
name = self.excel.get_casename(row)
level = self.excel.get_caselevel(row)
data = self.excel.get_casebody(row)
expect_res = self.excel.get_expectres(row)
method = self.excel.get_methodtype(row)
hasheader = self.excel.get_headerflag(row)
operator = self.excel.get_operator(row)
if isrun == "Y":
logging.info("Begin to run test case : %s,case number :%s" %(name,no))
logging.info("Request method type is :%s" %method)
logging.info("Request URL:%s" %url)
logging.info("Request Body:%s" %json.dumps(json.loads(data),sort_keys=True,indent=2))
res = send_request(method,url,data=data,headers=headers)
is_sucess = self.check.cmpdict(eval(expect_res),eval(res.text),operator)
print(is_sucess)
if is_sucess:
sucess_list.append(name)
#回写测试结果
self.excel.write_testres(row,"pass")
#回写实际结果
self.excel.write_actualres(row,res.text)
logging.info("Test case %s run sucess." %name)
else:
failed_list.append(name)
print("fail",is_sucess)
#回写测试结果
self.excel.write_testres(row,"failed")
#回写实际结果
self.excel.write_actualres(row,res.text)
logging.error("Test case %s run fail." %name)
logging.info("Response is:%s" %json.dumps(res.json(),sort_keys=True,indent=2))
else:
skip_list.append(name)
self.excel.write_testres(row,"skipped")
def sum(self):
total = len(sucess_list)+len(failed_list) + len(skip_list)
failed = len(failed_list)
sucess = len(sucess_list)
logging.info("-----------------------------------------------------------")
logging.info("本次一共运行：%s 个用例" %total)
logging.info("本次运行通过：%s 个用例" %sucess)
logging.info("本次运行跳过：%s 个用例" %len(skip_list))
logging.info("跳过的用例：%s" %skip_list)
logging.info("-----------------------------------------------------------")
在untils/run_main.py中方法cmpdict()是用来校验预期和结果实际结果是否匹配，需要传入三个参数：预期结果字典，实际结果字典，操作符。在check_result.py中编写校验用例结果的方法。目前只支持两种操作符，equal和notequal，预期结果为字典，其中不能嵌套字典。和完整代码如下：
from untils.log_trace import *
class CheckResult():
def dict_value(self,key,actual):
try:
if key in actual:
return actual[key]
else:
for keys in actual:
return self.dict_value(key,actual[keys])
except Exception as e:
logging.error(e)
return None
def cmpdict(self,expect,actual,equal):
logging.info("Begin to check result of testcase.")
is_dict = isinstance(expect,dict) and isinstance(actual,dict)
if is_dict:
if equal == "equal":
for key in expect.keys():
if expect[key] == self.dict_value(key,actual):
logging.info("%s is equal to %s" %(expect[key],self.dict_value(key,actual)))
return True
else:
logging.error("%s is not equal to %s" %(expect[key],self.dict_value(key,actual)))
return False
if equal == "notequal":
for key in expect.keys():
if key != self.dict_value(key,actual):
logging.info("%s is not equal to %s" %(expect[key],self.dict_value(key,actual)))
return True
else:
logging.error("%s is equal to %s" %(expect[key],self.dict_value(key,actual)))
return False
else:
logging.error("Operator :%s is not support now,you can define it in file[check_result.py]" %equal)
else:
logging.error("Expect or actual result is not dict,check it in excel. ")新建一个名称为test.xls的Excel，将其放到testcase路径下，并在Excel中编写测试用例。接口开发请参考：使用Django开发简单接口：文章增删改查，我准备的用例如下：
在untils/untils_test.py中导入run_mian模块来测试一下：
from untils.run_main import runner
if __name__ == "__main__":
#test_send_request()
runner = runner()
runner.join_case()
runner.sum()运行untils_test.py，然后去到Excel中查看运行结果：
report路径下查看测试用例运行日志，如下所示：
