java - 如何为此代码构建测试用例？我的 testFindEmployeeByID 有什么问题？

Question

如何为这段代码构建一个测试用例？请检查底部的我的 TestCase 示例。我的 testFindEmployeeByID 有什么问题？

public Employee findEmployeeByID(int employeeID) throws HRSSystemException{
    Employee result = null;
    try {
        PreparedStatement pStmt = conn
                .prepareStatement("select * from Employee where ID = ?");
        pStmt.setInt(1, employeeID);

        ResultSet rs = pStmt.executeQuery();
        if (rs.next()) {
            result = new EmployeeImpl(rs.getInt("ID"), 
                        rs.getString("FIRSTNAME"),
                        rs.getString("LASTNAME"), 
                        rs.getInt("LEVEL"));

        }
        rs.close();
        pStmt.close();
    } catch (SQLException e) {
        throw new HRSSystemException(HRSSystemException.ERROR_FIND_EMPLOYEE_ID,
                e);
    }
    return result;  
}

测试用例：

public void testFindEmployeeByID(){
    testFindEmployeeByID abc = new testFindByEmployeeID();
    Employee e = abc.findEmployeeByID(employeeID);
    assertEquals(1,e.getID);
}

Answer 1

testFindEmployeeByID()-method中的这部分看起来是错误的：

testFindEmployeeByID abc = new testFindByEmployeeID();

testFindEmployeeByID测试类名称也是？您可能打算实例化包含实际方法的类findEmployeeByID。
