private void executeSetUpOperation() throws Exception{
final IDatabaseConnection connection = this.getConnection();
try{
    DatabaseOperation.CLEAN_INSERT.execute(connection, this.getDataSet());
}finally{
    connection.close();
}
}

private IDataSet getDataSet() throws IOException, DataSetException {
return new FlatXmlDataSet(new File("test/conf/dbunit-user-seed.xml"));
}

private IDatabaseConnection getConnection() throws ClassNotFoundException, SQLException {
final Class driverClass = Class.forName("org.gjt.mm.mysql.Driver");
final Connection jdbcConnection = DriverManager.
getConnection("jdbc:mysql://localhost/ccb01",
"9043", "43xli");
return new DatabaseConnection(jdbcConnection);
}

private void verifyPassword(String fileName) throws Exception{
final IDataSet expectedDataSet = new FlatXmlDataSet(
new File(fileName));

final ITable defJoinData = this.getConnection().
   createQueryTable("TestResult",
    "select user.username, user.password " +
    "from user where user.username=\"jane\"");

final ITable defTable = expectedDataSet.getTable("user");
Assertion.assertEquals(defJoinData, defTable);
}
}

只多一个测试……

请注意这个测试用例没有测试边界用例，例如：如果两个口令字段（newPassword1 和 newPassword2()）不匹配。谢天谢地，一旦设置好了，添加另一个测试用例并不难。在清单 12 中，验证了如果两个值不匹配，就生成 ActionError，用户 “jane” 口令在数据库中的值保持不变。

清单 12. 添加新测试

public void testExecuteWithErrors() throws Exception{
setRequestPathInfo("/changePasswordSubmit");

   addRequestParameter("username","jane");
   addRequestParameter("currentPassword","admin");
   addRequestParameter("newPassword1","meme");
   addRequestParameter("newPassword2","emem");

   actionPerform();
   verifyActionErrors(
     new String[]{"error.changePassword.passwordsDontMatch"});
   verifyPassword("test/conf/dbunit-expect-user-same.xml");
}
