我正在使用 SimpleTest 1.0.1 使用 CakePHP(刚刚发布的 1.2.4)编写一个新应用程序。我已经阅读了Cookbook的相关部分,在Bakery上进行了搜索,并阅读了 Mark Story 关于控制器测试的帖子(hard way和mocks)。
不幸的是,这些都没有谈到对非平凡控制器的实际测试。许多应用程序将网站的某些区域放在登录后面,但我不知道如何测试以下简单场景:
- 访客访问受保护的页面重定向?
- 有效凭据设置预期的会话变量?
- 无效凭据重新显示带有错误消息的登录页面?
下面的控制器和测试没有像我想象的那样工作。两个断言都失败了,我也得到一个 PHP 错误:
FAILED [NULL] 在 [.../app/tests/cases/controllers/users_controller.test.php 第 79 行] .../app/tests/cases/controllers/users_controller.test.php -> UsersControllerTest 不应为空-> 测试登录
FAILED 相等期望失败,因为 [NULL] 不匹配 [Integer: 1] at [.../app/tests/cases/controllers/users_controller.test.php line 80] .../app/tests/cases/controllers/ users_controller.test.php -> UsersControllerTest -> testLogin
错误 [.../cake/libs/controller/components/auth.php 第 266 行] 中的意外 PHP 错误 [未定义索引:操作] 严重性 [E_NOTICE] .../app/tests/cases/controllers/users_controller.test。 php -> UsersControllerTest -> testLogin
这是控制器(baked plus Mark Story 的“hard way”测试方法):
class UsersController extends AppController
{
var $name = 'Users';
var $helpers = array('Html', 'Form');
var $components = array('Auth');
function login()
{
}
function logout()
{
$this->redirect($this->Auth->logout());
}
function index()
{
$this->set('users', $this->paginate());
}
function view($id = null)
{
if (!$id)
{
$this->Session->setFlash(__('Invalid User.', true));
$this->redirect(array('action'=>'index'));
}
$this->set('user', $this->User->read(null, $id));
}
function add()
{
if (!empty($this->data))
{
$this->User->create();
if ($this->User->save($this->data))
{
$this->Session->setFlash(__('The User has been saved', true));
$this->redirect(array('action'=>'index'));
}
else
{
$this->Session->setFlash(__('The User could not be saved. Please, try again.', true));
}
}
}
function edit($id = null)
{
if (!$id && empty($this->data))
{
$this->Session->setFlash(__('Invalid User', true));
$this->redirect(array('action'=>'index'));
}
if (!empty($this->data))
{
if ($this->User->save($this->data))
{
$this->Session->setFlash(__('The User has been saved', true));
$this->redirect(array('action'=>'index'));
}
else
{
$this->Session->setFlash(__('The User could not be saved. Please, try again.', true));
}
}
if (empty($this->data))
{
$this->data = $this->User->read(null, $id);
}
}
function delete($id = null)
{
if (!$id)
{
$this->Session->setFlash(__('Invalid id for User', true));
$this->redirect(array('action'=>'index'));
}
if ($this->User->del($id))
{
$this->Session->setFlash(__('User deleted', true));
$this->redirect(array('action'=>'index'));
}
}
}
这是测试:
