1.软件测试 Software Testing
是为了检查实际应用是否满足需求，为了保证应用的功能都能如期地正常运行。
Software Testing is a method to check if the actual application match the requirement, to ensure functionalities work properly as expected.
它的目的是为了在发布前找出错误，缺陷，不一致，需求缺失等问题
The purpose is to identify errors, defects, gaps, missing requirement .e.t before delivery to pulic release。
软件测试就是 测试主导软件验证
Software Testing means verification of application under test(AUT).
2.重要性 importance
