我想在不连接到 Yii 2 中的数据库的情况下测试我的 AR 模型,所以我使用 mockBuilder(),但我不知道如何将模拟对象传递给模型存在验证器,例如:
class Comment extends ActiveRecord
{
public function rules()
{
return [
[['id', 'user_id', 'post_id'], 'comment'],
['comment', 'string',
'max' => 200
],
['user_id', 'exist',
'targetClass' => User::className(),
'targetAttribute' => 'id'
],
['post_id', 'exist',
'targetClass' => Post::className(),
'targetAttribute' => 'id'
]
];
}
}
class CommentTest extends TestCase
{
public function testValidateCorrectData()
{
$user = $this->getMockBuilder(User::className())
->setMethods(['find'])
->getMock();
$user->method('find')->willReturn(new User([
'id' => 1
]));
$post = $this->getMockBuilder(Post::className())
->setMethods(['find'])
->getMock();
$post->method('find')->willReturn(new Post([
'id' => 1
]));
// How can I pass to $user and $post to exist validator in Comment model?
$comment = new Comment([
'user_id' => 1,
'post_id' => 1,
'comment' => 'test...'
]);
expect_that($comment->validate());
}
}
好的,这不是一个最好的代码,只是我想介绍一下我想做的事情。
Yii2 ExistValidator 使用 ActiveQuery::exists() 来检查是否存在,你应该将生成的验证器替换为 mockobject,其中方法 createQuery 返回 ActiveQuery 的 mockobject 其中 ::exists() 返回你想要的东西(真/假),例如
$activeQueryMock = $this->getMockBuilder(ActiveQuery::className())
->disableOriginalConstructor()
->setMethods(['exists'])
->getMock();
$activeQueryMock->expects($this->any())
->method('exists')
->willReturn($value); //Your value here true/false
$model = $this->getMockBuilder(Comment::className())
->setMethods(['getActiveValidators'])
->getMock();
$model->expects($this->any())
->method('getActiveValidators')
->willReturnCallback(function () use ($activeQueryMock) {
$validators = (new Comment())->activeValidators;
foreach ($validators as $key => $validator) {
if (($validator instanceof ExistValidator) && ($validator->attributes = ['user_id'])) {
$mock = $this->getMockBuilder(ExistValidator::className())
->setConstructorArgs(['config' => get_object_vars($validator)])
->setMethods(['createQuery'])
->getMock();
$mock->expects($this->any())
->method('createQuery')
->willReturn($activeQueryMock);
$validators[$key] = $mock;
break;
}
}
return $validators;
});
$model->validate();
