python使用eval动态调用函数及其在测试用例中断言的应用

理论：https://www.runoob.com/python/python-func-eval.html     eval() 函数用来执行一个字符串表达式，并返回表达式的值。

要解决的问题1：

实际编码中需要根据传参来确定调用哪个函数

示例代码：

getDisValue(self, itemKey, field) 与getItemsSql(self, itemname, field)

from config.config_reader import configReader
from common.save_test_result import getTestResult
from common.get_sql_value import getSqlValue
from common.get_display_value import getDisplayValue
from common.my_log import Logger
