我调查的项目是英语学习软件的改进,这个项目包含很广,这里,我选择了电脑被单词软件作为开发项目。
随着时代的发展,全球化越来越快,英语也就显得很重要,学习英语的人员也是日益增多,传统的查阅字典等方法已经不足以满足人们的需要。电脑的普及使得使用电脑被单词可以为每个人所接受,因此开发电脑背单词软件。
背单词软件的目的就是建立一个客户平台,用户使用此平台进行单词翻译、单词查询、加入生词库等。
要求主要实现以下功能模块:
1) 用户能够导入导出词库;
2) 用户可以选择是否显示单词的音标、中文解释等;
3) 用户可以选择屏幕前端显示的单词的更新速度、背景和前景等;
4) 用户可以拖动显示的单词条到屏幕的任何位置;
5) 提供生词本功能,用户可以随时添加生词,并选择生词库作为当前词库。
首先是用户登录
登录成功后可进行四种操作,一是查询,二是查看,三是修改密码,四是生词库(查询如下)
使用access进行数据库设计,主要包括四个表:
登录:
public void actionPerformed(ActionEvent e) {
if (e.getSource() == enroll) {
new EnrollWindow();
} else if (e.getSource() == login) {
String log_sno = tsno.getText();
String log_spwd = ppwd.getText();
DataBase db = new DataBase();
if (log_sno==null || log_spwd==null) {
JOptionPane.showMessageDialog(rootPane, "登陆信息不全,请补充");
} else {
if (db.isValidUser(log_sno, log_spwd)) {
isLogin = true;
JOptionPane.showMessageDialog(rootPane, "欢迎回来," + db.getSname(log_sno) + "。您可以使用您的生词本等个性化功能了!");
dic.writeToWordbok.setEnabled(true);
dic.wordbook.setEnabled(true);
currentSname = db.getSname(log_sno);
currentSno = log_sno;
p5.removeAll();
p5.revalidate();
p5.add(new JLabel("欢迎回来,"));
p5.add(new JLabel(db.getSname(log_sno)));
p5.add(new JLabel("上次学习:"));
p5.add(new JLabel("2012-03-10"));
p5.add(new JLabel("总共学习:"));
p5.add(new JLabel("5 次"));
} else {
JOptionPane.showMessageDialog(rootPane, "信息错误,登陆失败");
}
}
}
}

登入测试:在登入测试是在登入页面开始在输入用户名和密码登入时自动区分主页和用户,使主页管理员在进入主页后能使用后台功能。登入测试用例表6-1所示:
表5-1登入测试用例
用例名称 |
登入测试 |
基本描述 |
管理员登录测试就是用户输入的用户名和密码进行管理员登录,系统判断该用户的输入是否合法,对此功能进行测试。 |
测试方案 |
分别使用系统承认的主页管理员用户名及密码、注册的游客的用户名和密码和未注册的用户名和密码进行测试。 |
输入数据 |
1用户名111和密码1234 2用户名2和密码123456 3用户名aaa和密码321 |
预期结果 |
第一组主页管理员用户名及密码成功登录主页,并能使用后台界面 第二组注册游客用户名及密码成功登录主页,但不能使用柜员操作 第三组未注册的用户名和密码不能登入主页,提示错误信息 |
输入正确的用户名和密码
输入错误的用户名、密码
