Laravel 4 Model Events don't work with PHPUnit
I build a model side validation in Laravel 4 with the creating Model Event :
class User extends Eloquent {
public function isValid()
{
return Validator::make($this->toArray(), array('name' => 'required'))->passes();
}
public static function boot()
{
parent::boot();
static::creating(function($user)
{
echo "Hello";
if (!$user->isValid()) return false;
});
}
}
It works well but I have issues with PHPUnit. The two following tests are exactly the same but juste the first one pass :
class UserTest extends TestCase {
public function testSaveUserWithoutName()
{
$count = User::all()->count();
$user = new User;
$saving = $user->save();
assertFalse($saving); // pass
assertEquals($count, User::all()->count()); // pass
}
public function testSaveUserWithoutNameBis()
{
$count = User::all()->count();
$user = new User;
$saving = $user->save();
assertFalse($saving); // fail
assertEquals($count, User::all()->count()); // fail, the user is created
}
}
If I try to create a user twice in the same test, it works, but it's like if the binding event is present only in the first test of my test class. The echo "Hello"; is printed only one time, during the first test execution.
I simplify the case for my question but you can see the problem : I can't test several validation rules in different unit tests. I try almost everything since hours but I'm near to jump out the windows now ! Any idea ?
The issue is well documented in Github. See comments above that explains it further.
I've modified one of the 'solutions' in Github to automatically reset all model events during the tests. Add the following to your TestCase.php file.
app/tests/TestCase.php
public function setUp()
{
parent::setUp();
$this->resetEvents();
}
private function resetEvents()
{
// Get all models in the Model directory
$pathToModels = '/app/models'; // <- Change this to your model directory
$files = File::files($pathToModels);
// Remove the directory name and the .php from the filename
$files = str_replace($pathToModels.'/', '', $files);
$files = str_replace('.php', '', $files);
// Remove "BaseModel" as we dont want to boot that moodel
if(($key = array_search('BaseModel', $files)) !== false) {
unset($files[$key]);
}
// Reset each model event listeners.
foreach ($files as $model) {
// Flush any existing listeners.
call_user_func(array($model, 'flushEventListeners'));
// Reregister them.
call_user_func(array($model, 'boot'));
}
}
我在子目录中有我的模型，所以我编辑了一下@TheShiftExchange代码
//Get all models in the Model directory
$pathToModels = '/path/to/app/models';
$files = File::allFiles($pathToModels);
foreach ($files as $file) {
$fileName = $file->getFileName();
if (!ends_with($fileName, 'Search.php') && !starts_with($fileName, 'Base')) {
$model = str_replace('.php', '', $fileName);
// Flush any existing listeners.
call_user_func(array($model, 'flushEventListeners'));
// Re-register them.
call_user_func(array($model, 'boot'));
}
}
