【第七章】优化request_utils库,结合断言库,添加异常处理模块

• 结合断言库优化request_uitls底层数据

• 先在check_utils新增通过结果跟失败结果

    def __init__(self, response_data):
        self.response_data = response_data
        self.function = {
            "none": self.__none_check,
            "json_key": self.__key_check,
            "json_key_value": self.__key_value_check,
            "body_regexp": self.__body_regexp_check,
            "header_key_check": self.__header_key_check,
            "header_key_value_check": self.__header_key_value_check,
            "response_code_check": self.__response_code_check

        }
        self.pass_result = {  # 通过结果
            "code": 0,
            "response_code": self.response_data.status_code,
            "response_reason": self.response_data.reason,
            "response_headers": self.response_data.headers,
            "response_body": self.response_data.text,
            "message": "测试用例执行通过",
            "check_result": True
        }
        self.fail_result = {  # 失败结果 2 表示断言失败
            "code": 2,
            "response_code": self.response_data.status_code,
            "response_reason": self.response_data.reason,
            "response_headers": self.response_data.headers,
            "response_body": self.response_data.text,
            "message": "测试用例断言失败，测试用例执行不通过",
            "check_result": False
        }

　　

• 将原来的result替换成check_utils的断言方法

        variables_list = re.findall('\\${.+?}', request_info["请求参数(get)"])
        for variable in variables_list:
            request_info["请求参数(get)"] = request_info["请求参数(get)"].replace(variable, self.temp_variables[variable[2:-1]])

        response = self.session.get(url=url,
                                    params=json.loads(request_info["请求参数(get)"]),
                                    # params=json.loads(
                                    #     requests_info['请求参数(get)'] if requests_info['请求参数(get)'] else None),
                                    headers=json.loads(request_info["请求头部信息"]) if request_info["请求头部信息"] else None
                                    )
        if request_info["取值方式"] == "正则取值":
            value = re.findall(request_info["取值代码"], response.text)[0]
            self.temp_variables[request_info["取值变量"]] = value
        elif request_info["取值方式"] == "jsonpath取值":
            value = jsonpath.jsonpath(response.json(), request_info["取值代码"])[0]
            self.temp_variables[request_info["取值变量"]] = value

        # 将原来的替换成断言库
        result = CheckUtils(response).run_check(request_info["断言类型"], request_info["期望结果"])
        return result

• 日志模块

• 配置文件新增log_path

• config_uitls.py 新增方法

• nb_log_config.py 引入logs路径

• 封装日志模块
