Yii - Unittesting Model Download Forms

Question

I have the following upload model

class TestUploadForm extends CFormModel { public $test; public function rules() { return array( array(test, 'file', 'types' => 'zip, rar'), ); } 

My question is: how can I unit test this? I tried something like:

 public $testFile = 'fixtures/files/yii-1.1.0-validator-cheatsheet.pdf'; public function testValidators() { $testUpload = new TestUploadForm; $testUpload->test = $this->testFile ; assertTrue($testUpload ->validate()); $errors= $testUpload ->errors; assertEmpty($errors); } 

However, this tells me that the field is blank. How to unit test extension rules?

Answer 1

As we know, Yii uses CUploadedFile to upload files, we must use it to initialize the model file attribute.

We can use the constructor to initialize the file attribute new CUploadedFile($names, $tmp_names, $types, $sizes, $errors);

Therefore, we can do this:

 public ValidatorTest extends CTestCase{ public $testFile = array( 'name'=>'yii-1.1.0-validator-cheatsheet.pdf', 'tmp_name'=>'/private/var/tmp/phpvVRwKT', 'type'=>'application/pdf', 'size'=>100, 'error'=>0 ); public function testValidators() { $testUpload = new TestUploadForm; $testUpload->test = new CUploadedFile($this->testFile['name'],$this->testFile['tmp_name'],$this->testFile['type'],$this->testFile['size'],$this->testFile['error']); $this->assertTrue($testUpload->validate()); $errors= $testUpload->errors; $this->assertEmpty($errors); } } 

CFileValidator takes into account the extension for determining the type , so to check your validator you will need to continue to change the name of $testFile , i.e. $testFile['name']='correctname.rar' .

So, we really do not need the file anywhere, just the file information is enough for testing.
