實現需求2：
有兩種運行測試的方式：
- 通過config配置文件運行，測試只需要修改config配置文件
- cmdline 運行
這里是新建一個config類來存儲所有的測試配置，以后配置有修改的話也只需要修改這個類。
根據目前的測試需求，config中有以下幾個屬性：
| 屬性 | 作用 | 備注 |
|---|---|---|
| list_test???????? | 按case list的flag，為True時生效 | |
| single_test | 單條運行case的flag，為True時生效 | |
| repeat? ? ?? | case重復運行的次數 | |
| risk_analysis | 高風險case分析 | 功能暫未實現 |
| tester? ? ? ? ? ? ?? | 測試者的用戶名，作為測試者發送郵件的收件人 | |
| case_list | 存儲測試case集，從這里取出需要運行的測試 |
具體類代碼為：
class TestConfig:"""測試配置管理"""_results_file = "test_results.json"_test_history = {}def __init__(self,list_test=False, single_test=False, repeat=1, case_list=None, risk_analysis=False,tester = None):self.list_test = list_testself.single_test = single_testself.repeat = repeatself.case_list = case_listself.risk_analysis = risk_analysisself.tester = tester雖然有兩種運行腳本的方式，但是通過這兩種方式獲取的信息都會填充到config這個類中，然后從這個類中讀取當前需要運行的配置信息。 默認從配置文件中讀取測試信息，當配置文件不存在時，從cmdline中讀取測試信息。
最上層代碼實現：
def get_test_config(self, config):"""1. read config from config file2. check flag of test config . if true , read test config from config fileif false , read test config from cmdline:param config: Object of Class TestConfig"""split_str = "="config_list = self.read_config_from_file(CONFIG_FILE)run_from_cfg_file = ast.literal_eval(config_list[0].split(split_str)[1].strip())if run_from_cfg_file:logger.info("reading test config from config file ......")self.parse_settings_to_config(config_list, config)else:self.read_config_from_cmdline(config)logger.info("getting test config from cmdline ......")讀取配置文件
配置文件中包含兩類信息：
- 當前配置文件是否有效的flag(True or False)，后面會根據這個flag來決定讀取config file還是cmdline
- 測試的具體信息，用于填充TestConfig對象的
代碼實現：返回一個包含配置信息的list
def read_config_from_file(self, file_path):# config_file = "config_file.txt"# # get path of config_file.txt# file_path = os.path.join(os.getcwd(), config_file)config_list = []# check if config file is exist# if self.__file_exist_check(file_path):if self.config_file_status(file_path):try:with open(file_path) as file_handle:lines = file_handle.readlines()for line in lines:config_list.append(line.strip())except FileNotFoundError as e:logger.exception(f"file not found:{e}")except PermissionError as e:logger.exception(f"No permission to read the file:{e}")except Exception as e:logger.exception(f"file not found: {e}")return config_list # config_list 正確else:logger.error("Config file is not exist....Please check again,Test Stop......")exit()配置文件config_file.txt的內容為：
?--use_config=False
--list_test=True
--single_test=False
--case_list =test_list.txt
--repeat=15
--risk_analysis=False
--tester=TestUser
判斷是否使用配置文件
通過run_from_cfg_file 這個flag來判斷是讀取配置文件還是讀取cmdline
"""flag of run method ,from config file , or from cmdline
"""
run_from_cfg_file = False# config_list 為read_config_from_file()返回的config list
run_from_cfg_file = ast.literal_eval(config_list[0].split(split_str)[1].strip())if run_from_cfg_file:logger.info("reading test config from config file ......")self.parse_settings_to_config(config_list, config)else:self.read_config_from_cmdline(config)logger.info("getting test config from cmdline ......")若run_from_cfg_file 為True，則從配置文件中讀取測試配置并調用方法parse_settings_to_config()填充到TestConfig對象中
# fill test settings to TestConfig objectdef parse_settings_to_config(self, arg_list, config):split_str = "="for item in arg_list:if "--list_test" in item:config.list_test = ast.literal_eval(item.split(split_str)[1].strip()) # transfer from string to bool typeelif "--single_test" in item:config.single_test = ast.literal_eval(item.split(split_str)[1].strip()) # transfer from string to bool typeelif "--case_list" in item:config.case_list = item.split(split_str)[1].strip()elif "--repeat" in item:config.repeat = item.split(split_str)[1].strip()elif "--risk_analysis" in item:config.risk_analysis = ast.literal_eval(item.split(split_str)[1].strip()) # transfer from string to bool typeelif "--tester=TestUser" in item:config.tester = item.split(split_str)[1].strip()若run_from_cfg_file 為False，則調用方法read_config_from_cmdline()將cmdline中的配置填充到TestConfig配置中去。
def get_cmdline_args(self):list = sys.argvreturn listdef read_config_from_cmdline(self,config):self.parse_settings_to_config(self.get_cmdline_args(),config)至此通過配置文件和cmdline分別獲取測試配置信息的task就已經完成了。讀取配置信息的工作都是在tef_funtcion.py中的class FunctionApi中來完成的。完整代碼為：
