Overview

Classical method creating of mock

class CartServiceTest extends \PHPUnit_Framework_TestCase
{
// provider etc.publicfunctionaddProductTest($product, $expectations)
{
$cart = newCartService(
$this->createMockOfDatabase()
);
// some test and assertions
}
privatefunctioncreateMockOfDatabase()
{
$values = [0, 1, 2];
$statement = $this->getMockBuilder(\PDOStatement::class)
->disableOriginalConstructor()
->getMock();
$statement->method('fetchAll')->willReturn($values);
$pdo = $this->getMockBuilder(\PDO::class)
->disableOriginalConstructor()
->getMock();
$pdo->method('query')->willReturn($statement);
return$pdo;
}
}

Creating the same mock with the YMock

class CartServiceTest extends \PHPUnit_Framework_TestCase
{
// provider etc.publicfunctionaddProductTest($product, $expectations)
{
$ymock = new \SyntaxErro\YMock\YMock($this, './path/to/mocks.yml');
$mocks = $ymock->getMocks();
$cart = newCartService(
$mocks->get('valid_query_database_connection')
);
// some test and assertions
}
}

valid_query_database_connection:
class: "\\PDO"disable_original_constructor: truemethods:
query:
class: "\\PDOStatement"disable_original_constructor: truemethods:
fetchAll: [0, 1, 2]
