springboot075电影评论网站系统设计与实现

表4.9 用户

电影评论网站的系统管理员可以管理学生，可以对电影信息添加修改删除以及查询操作。具体界面的展示如图5.1所示。

系统管理员可以查看对电影评论进行回复操作。具体界面如图5.2所示。

用户可以对电影信息进行收藏，评论操作。界面如下图所示：

用户只有注册了才可以进行登录。界面如下图所示：

任务：消除软件故障，保证程序的可靠运行。测试与纠错的关系，可以用图6-1的数据流图来说明。图中表明，每一次测试都要准备好若干必要的测试数据，与被测试程序一道送入计算机执行。通常把一次程序执行需要的测试数据，称为一个“测试用例(Test Case)。每一个测试用例产生一个相应的“测试结果”。如果它与“期望结果”不想符合，便说明程序中存在错误，需要用纠错来改正。
