Bagaimana untuk mengejek Mage::getSingleton('checkout/cart') dalam php-unit?
Saya mempunyai kaedah foo() ini dan saya perlu menambah kes ujian unit untuk kaedah ini testFoo() dalam Magento. Tetapi Mage::getSingleton('checkout/cart') tidak boleh disimulasikan.
Kaedah sumber
public function foo()
{
return Mage::getSingleton('checkout/cart')->getQuote()->getFunctionName();
}
Fungsi ujian
public function testFoo(): void
{
//$this->className :: Project_Catalog_Helper_Test
$expected = 'string';
$this->className->method('getSingleton')->willReturn($this->cart);
$this->cart->method('getQuote')->willReturn($this->cart);
$this->cart->method('getFunctionName')->willReturn('string');
$this->assertEquals(
$this->className->foo(),
$expected
);
}
Apabila saya menjalankan php-unit saya mendapat log ralat ini.
MacBook-Pro % ./vendor/bin/phpunit tests/src/app/code/local/project/Catalog/Helper/OrderTest.php PHPUnit 6.5.14 by Sebastian Bergmann and contributors. Runtime: PHP 7.3.11 Configuration: /project_path/phpunit.xml.dist E 1 / 1 (100%) Time: 150 ms, Memory: 8.00MB There was 1 error: 1) Project_Catalog_Helper_Test::testFoo Error: Call to a member function getCode() on bool /project_path/app/code/core/Mage/Customer/Model/Session.php:103 /project_path/app/code/core/Mage/Core/Model/Config.php:1394 /project_path/app/Mage.php:517 /project_path/app/Mage.php:531 /project_path/app/code/community/Checkout/Model/Cart.php:20 /project_path/app/code/local/project/Catalog/Helper/Order.php:21 /project_path/tests/src/app/code/local/project/Catalog/Helper/OrderTest.php:100 /project_path/vendor/phpunit/phpunit/phpunit:53
Perlukan beberapa penyelesaian, cara mensimulasikan Mage::getSingleton('checkout/cart').
Nota: Saya tidak boleh menukar kaedah utama kerana ia adalah kod warisan. Hanya tambah kes ujian unit.
