Hello,

I have an Orm model for users. Now I'm trying to write a test case using PHPUnit_Selenium package. I've written several test cases before successfully with Selenium but now I've encountered a problem with ORM's caching mechanisms.

Code for the test case:
function test_edit_user_data()
{
// Load user data
$user = Model_User::find(1);
// Now $user->name is 'Old Name'

// Using the PHPUnit Selenium functions, make a request to
// my app that should change $user name
$this->url('http://example.dev/edit-user-data/');

// Reload the data
$user = Model_User::find(1);

// Verify that the name has is indeed been edited
$this->assertEquals($user->name, 'New Name'); // here the test fails as $user->name is still 'Old Name'
}

If I check the my DB after the test, the user's name is 'New Name'. So I assume the caching in ORM is taking data from cache instead of the DB when I try to reload the data. I tried to reload user data with a different primary key field ( $user = Model_User::find_by_email('user@example.com') ) but this also gives me the old data.

So is there a way to bypass the cache? Or maybe clear it?

Correct. A second request for the same data will reproduce the data from cache.

You can reset the cache from inside the model (as the properties are protected) using:

$class = get_called_class();
unset(static::$_cached_objects[$class]);

You'll have to create a method for that so you can call that from the test.

Alternatively you can use reflection to make the $_cached_objects accessable for your test, and unset it from there.

That solved my problem. Thank you!
