I'm pretty new to Phpspec testing and I don't know what is the correct way to test multiple scenarios when transforming a object to different response structure.
I need to check if price is correctly calculated. Here I have the Transformer spec test:
/**
* @dataProvider pricesProvider
*/
public function it_should_check_whether_the_prices_are_correct(
$priceWithoutVat,
$priceWithVat,
$vat,
Request $request,
Repository $repository
) {
$productIds = array(100001);
$result = array(
new Product(
'100001',
'MONSTER',
new Price(
$priceWithoutVat,
20,
'GBP',
null,
null
)
)
);
$expected = array(
array(
"productId" => "100001",
"brand" => "MONSTER",
"price" => array(
"amount" => $priceWithVat,
"vatAmount" => $vat,
"currencyCode" => "GBP",
"discountAmount" => (int)0
)
)
);
$repository->getResult(array(
Repository::FILTER_IDS => $productIds
))->willReturn($result);
$request->get('productIds')->willReturn(productIds);
/** @var SubjectSpec $transformedData */
$transformedData = $this->transform($request);
$transformedData->shouldEqual($expected);
}
public function pricesProvider()
{
return array(
array('123.456789', 14814, 2469),
array('60.00', 7200, 1200),
);
}
In my Transformer class I have a function which formats data to the correct format:
public function transform(Request $request)
{
$productIds = $request->get('productIds');
$productsResult = $this->repository->getResult(array(
Repository::FILTER_IDS => $productIds
));
$products = array();
foreach ($productsResult as $product) {
$products[] = $this->formatData($product);
}
return $products;
}
/**
* @param Product $product
* @return array
*/
private function formatData(Product $product)
{
return array(
'productId' => $product->getId(),
'brand' => $product->getBrandName(),
'price' => array(
'amount' => (int)bcmul($product->getPrice()->getAmountWithTax(), '100'),
'vatAmount' => (int)bcmul($product->getPrice()->getTaxAmount(), '100'),
'currencyCode' => $product->getPrice()->getCurrencyCode(),
'discountAmount' => (int)bcmul($product->getPrice()->getDiscountAmount(), '100')
)
);
}
The problem is, that I'm getting this error message:
316 - it should check whether the prices are correct
warning: bcmul() expects parameter 1 to be string, object given in
/src/AppBundle/Database/Entity/Product/Price/Price.php line 49
If I hard-code those values then the test is green. However I want to test varios prices and results, so I decided to use the dataProvider method. But when dataProvider passes the $amountWithoutTax value, it's not string but PhpSpec\Wrapper\Collaborator class and because of this the bcmul fails.
If I change the $amountWithoutTax value to $priceWithoutVat->getWrappedObject() then Double\stdClass\P97 class is passed and because of this the bcmul fails.
How do I make this work? Is it some banality or did I completely misunderstood the concept of this?
