Unit-testing with CakePhP and PHPUnit - unit-testing

Question

I`m trying to do unit-testing with CakePhP 2.3 and PHPUnit 2.7. I want to test the index function in my customer’s controller.
In my controller I have:
public function index() {
$this->Customer->recursive = -1;
$data = $this->paginate('Customer', array( 'Customer.status'=>'active'));
$this->set('customers', $data);
}
I tried to follow the examples in book.cakephp.org, so I created Fixture class in which I`m importing the Customer schema and all the records.
class CustomerFixture extends CakeTestFixture{
public $import = array('model' => 'Customer', 'records' => true);
}
And finally my test class looks like this:
class CustomersControllerTest extends ControllerTestCase {
public $fixtures = array('app.customer');
public function testIndex() {
$result = $this->testAction('/customers/index');
debug($result);
}
}
When I run my test I have the following error:
Database Error
Error: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '8' for key 'PRIMARY'
Do you have any ideas what can be the problem?

Answer 1

In your database.php in app/Config folder you have to add a $test variable.
For example
class DATABASE_CONFIG {
public $default = array(
'datasource' => 'Database/Mysql',
'persistent' => true,
'host' => 'localhost',
'port' => 3306,
'login' => 'root',
'password' => 'xxxx',
'database' => 'mydatabase',
'encoding' => 'utf8'
);
public $test = array(
'datasource' => 'Database/Mysql',
'persistent' => false,
'host' => 'localhost',
'port' => 3306,
'login' => 'root',
'password' => 'xxxx',
'database' => 'mydatabase_test',
'encoding' => 'utf8'
);
}
Then your unit testing will use the mydatabase_test for testing your code. Because now it uses the default database.
