实现需求2：
有两种运行测试的方式：
- 通过config配置文件运行，测试只需要修改config配置文件
- cmdline 运行
这里是新建一个config类来存储所有的测试配置，以后配置有修改的话也只需要修改这个类。
根据目前的测试需求，config中有以下几个属性：
| 属性 | 作用 | 备注 |
|---|---|---|
| list_test | 按case list的flag，为True时生效 | |
| single_test | 单条运行case的flag，为True时生效 | |
| repeat | case重复运行的次数 | |
| risk_analysis | 高风险case分析 | 功能暂未实现 |
| tester | 测试者的用户名，作为测试者发送邮件的收件人 | |
| case_list | 存储测试case集，从这里取出需要运行的测试 |
具体类代码为：
class TestConfig:"""测试配置管理"""_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虽然有两种运行脚本的方式，但是通过这两种方式获取的信息都会填充到config这个类中，然后从这个类中读取当前需要运行的配置信息。 默认从配置文件中读取测试信息，当配置文件不存在时，从cmdline中读取测试信息。
最上层代码实现：
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 ......")读取配置文件
配置文件中包含两类信息：
- 当前配置文件是否有效的flag(True or False)，后面会根据这个flag来决定读取config file还是cmdline
- 测试的具体信息，用于填充TestConfig对象的
代码实现：返回一个包含配置信息的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 正确else:logger.error("Config file is not exist....Please check again,Test Stop......")exit()配置文件config_file.txt的内容为：
--use_config=False
--list_test=True
--single_test=False
--case_list =test_list.txt
--repeat=15
--risk_analysis=False
--tester=TestUser
判断是否使用配置文件
通过run_from_cfg_file 这个flag来判断是读取配置文件还是读取cmdline
"""flag of run method ,from config file , or from cmdline
"""
run_from_cfg_file = False# config_list 为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 为True，则从配置文件中读取测试配置并调用方法parse_settings_to_config()填充到TestConfig对象中
# 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 为False，则调用方法read_config_from_cmdline()将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)至此通过配置文件和cmdline分别获取测试配置信息的task就已经完成了。读取配置信息的工作都是在tef_funtcion.py中的class FunctionApi中来完成的。完整代码为：
