接口自动化是指模拟程序接口层面的自动化，由于接口不易变更，维护成本更小，所以深受各大公司的喜爱。
第一版入口：接口自动化框架(Pytest+request+Allure)
本次版本做了一些升级，增加了自动生成testcase等，一起来看看吧！～～
一、简单介绍
环境：Mac+Python 3+Pytest+Allure+Request
流程：Charles导出接口数据-自动生成测试用例-修改测试用例-执行测试用例-生成Allure报告
开源： 点击这里，跳转到github
备注??：Charles导出接口应选择文件类型为JSON Session File(.chlsj)
重要模块介绍：
1、writeCase.py ：自动读取新的Charles文件，并自动生成测试用例
2、apiMethod.py：封装request方法，可以支持多协议扩展（get\post\put）
3、checkResult.py：封装验证response方法
4、setupMain.py： 核心代码，定义并执行用例集，生成报告

二、目录介绍
三、代码分析
1、测试数据yml(自动生成的yml文件)
# 用例基本信息
test_info:
# 用例标题，在报告中作为一级目录显示
title: blogpost
# 用例ID
id: test_reco_01
# 请求的域名，可写死，也可写成模板关联host配置文件
host: ${host}$
# 请求地址 选填（此处不填，每条用例必填)
address: /api/v2/recomm/blogpost/reco
# 前置条件，case之前需关联的接口
premise:
# 测试用例
test_case:
- test_name: reco_1
# 第一条case，info可不填
info: reco
# 请求协议
http_type: https
# 请求类型
request_type: POST
# 参数类型
parameter_type: application/json
# 请求地址
address: /api/v2/recomm/blogpost/reco
# 请求头
headers:
# parameter为文件路径时
parameter: reco.json
# 是否需要获取cookie
cookies: False
# 是否为上传文件的接口
file: false
# 超时时间
timeout: 20
# 校验列表 list or dict
# 不校验时 expected_code, expected_request 均可不填
check:
expected_request: result_reco.json
check_type: only_check_status
expected_code: 503
# 关联键
relevance:
2、测试case(自动生成的case.py)
@allure.feature(case_dict["test_info"]["title"])
class TestReco:
@pytest.mark.parametrize("case_data", case_dict["test_case"], ids=[])
@allure.story("reco")
@pytest.mark.flaky(reruns=3, reruns_delay=3)
def test_reco(self, case_data):
"""
:param case_data: 测试用例
:return:
"""
self.init_relevance = ini_request(case_dict, PATH)
# 发送测试请求
api_send_check(case_data, case_dict, self.init_relevance, PATH)
3、writeCase.py (封装方法：自动生成测试case)
def write_case(_path):
yml_list = write_case_yml(_path)
project_path = str(os.path.abspath('.').split('/bin')[0])
test_path = project_path+'/aff/testcase/'
src = test_path+'Template.py'
for case in yml_list:
yml_path = case.split('/')[0]
yml_name = case.split('/')[1]
case_name = 'test_' + yml_name + '.py'
new_case = test_path + yml_path + '/' + case_name
mk_dir(test_path + yml_path)
if case_name in os.listdir(test_path + yml_path):
pass
else:
shutil.copyfile(src, new_case)
with open(new_case, 'r') as fw:
source = fw.readlines()
n = 0
with open(new_case, 'w') as f:
for line in source:
if 'PATH = setupMain.PATH' in line:
line = line.replace("/aff/page/offer", "/aff/page/%s" % yml_path)
f.write(line)
n = n+1
elif 'case_dict = ini_case' in line:
line = line.replace("Template", yml_name)
f.write(line)
n = n + 1
elif 'class TestTemplate' in line:
line = line.replace("TestTemplate", "Test%s" % yml_name.title().replace("_", ""))
f.write(line)
n = n + 1
elif '@allure.story' in line:
line = line.replace("Template", yml_name)
f.write(line)
n = n + 1
elif 'def test_template' in line:
line = line.replace("template", yml_name.lower())
f.write(line)
n = n + 1
else:
f.write(line)
n += 1
for i in range(n, len(source)):
f.write(source[i])
4、apiMethod.py(封装方法：http多协议)
def post(header, address, request_parameter_type, timeout=8, data=None, files=None):
"""
post请求
:param header: 请求头
:param address: 请求地址
:param request_parameter_type: 请求参数格式（form_data,raw）
:param timeout: 超时时间
:param data: 请求参数
:param files: 文件路径
:return:
"""
if 'form_data' in request_parameter_type:
for i in files:
value = files[i]
if '/' in value:
file_parm = i
files[file_parm] = (os.path.basename(value), open(value, 'rb'))
enc = MultipartEncoder(
fields=files,
boundary='--------------' + str(random.randint(1e28, 1e29 - 1))
)
header['Content-Type'] = enc.content_type
response = requests.post(url=address, data=enc, headers=header, timeout=timeout)
else:
response = requests.post(url=address, data=data, headers=header, timeout=timeout, files=files)
try:
if response.status_code != 200:
return response.status_code, response.text
else:
return response.status_code, response.json()
except json.decoder.JSONDecodeError:
return response.status_code, ''
except simplejson.errors.JSONDecodeError:
return response.status_code, ''
except Exception as e:
logging.exception('ERROR')
logging.error(e)
raise
5、checkResult.py(封装方法：校验response结果)
def check_result(test_name, case, code, data, _path, relevance=None):
"""
校验测试结果
:param test_name: 测试名称
:param case: 测试用例
:param code: HTTP状态
:param data: 返回的接口json数据
:param relevance: 关联值对象
:param _path: case路径
:return:
"""
# 不校验结果
if case["check_type"] == 'no_check':
with allure.step("不校验结果"):
pass
# json格式校验
elif case["check_type"] == 'json':
expected_request = case["expected_request"]
if isinstance(case["expected_request"], str):
expected_request = readExpectedResult.read_json(test_name, expected_request, _path, relevance)
with allure.step("JSON格式校验"):
allure.attach("期望code", str(case["expected_code"]))
allure.attach('期望data', str(expected_request))
allure.attach("实际code", str(code))
allure.attach('实际data', str(data))
if int(code) == case["expected_code"]:
if not data:
data = "{}"
check_json(expected_request, data)
else:
raise Exception("http状态码错误！\n %s != %s" % (code, case["expected_code"]))
# 只校验状态码
elif case["check_type"] == 'only_check_status':
with allure.step("校验HTTP状态"):
allure.attach("期望code", str(case["expected_code"]))
allure.attach("实际code", str(code))
allure.attach('实际data', str(data))

if int(code) == case["expected_code"]:
result = operator.eq(expected_request, data)
if result:
pass
else:
raise Exception("完全校验失败！ %s ! = %s" % (expected_request, data))
else:
raise Exception("http状态码错误！\n %s != %s" % (code, case["expected_code"]))
# 正则校验
elif case["check_type"] == 'Regular_check':

try:

for i in case[""]:
result = re.findall(i.replace("\"","\""), str(data))

allure.attach('正则表达式', str(case["expected_request"]).replace("\'", "\""))
allure.attach("实际code", str(code))
allure.attach('实际data', str(data))
allure.attach(case["expected_request"].replace("\"", "\'") + '校验完成结果',
str(result).replace("\'", "\""))
if not result:
raise Exception("正则未校验到内容！ %s" % case["expected_request"])

else:
raise Exception("http状态码错误！\n %s != %s" % (code, case["expected_code"]))
else:
raise Exception("无该校验方式%s" % case["check_type"])
6、setupMain.py(执行用例集，生成测试报告)
def invoke(md):
output, errors = subprocess.Popen(md, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()
o = output.decode("utf-8")
return o
if __name__ == '__main__':
LogConfig(PATH)
write_case(har_path)
args = ['-s', '-q', '--alluredir', xml_report_path]
pytest.main(args)
cmd = 'allure generate %s -o %s' % (xml_report_path, html_report_path)
invoke(cmd)
