O Guia Definitivo do Yii 1.1

$yiit='path/to/yii/framework/yiit.php';
$config=dirname(__FILE__).'/../config/test.php';
require_once($yiit);
require_once(dirname(__FILE__).'/WebTestCase.php');
Yii::createWebApplication($config);
In the above, we first include the yiit.php file from the Yii framework, which initializes some
global constants and includes necessary test base classes. We then create a Web
application instance using the test.phpconfiguration file. If we check test.php, we shall find
that it inherits from the main.php configuration file and adds a fixture application
component whose class is CDbFixtureManager. We will describe fixtures in detail in the
next section.
return CMap::mergeArray(
require(dirname(__FILE__).'/main.php'),
array(
'components'=>array(
'fixture'=>array(
'class'=>'system.test.CDbFixtureManager',
),
/* uncomment the following to provide test database connection
'db'=>array(
'connectionString'=>'DSN for test database',
),
*/
),
)
);
When we run tests that involve database, we should provide a test database so that the
test execution does not interfere with normal development or production activities. To do
so, we just need to uncomment the dbconfiguration in the above and fill in the
connectionString property with the DSN (data source name) to the test database.
With such a bootstrap script, when we run unit tests, we will have an application instance
that is nearly the same as the one that serves for Web requests. The main difference is
that it has the fixture manager and is using the test database.
Definindo Fixtures
Automated tests need to be executed many times. To ensure the testing process is
repeatable, we would like to run the tests in some known state called fixture. For example,
to test the post creation feature in a blog application, each time when we run the tests, the
tables storing relevant data about posts (e.g. the Post table, the Comment table) should be
