接口自动化框架---升级版(Pytest+request+Allure)

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

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)
