In my test class I insert new products and pricebookentries, in my test class I don't use seeAllDate=true annotation and in order to retrieve standard pricebook id I used Test.getStandardPricebookId() method, here's my code:

Product2 p1 = new Product2(Name='Product Monthly 1111', Family='Monthly', isActive=true, CurrencyIsoCode='USD');
Product2 p2 = new Product2(Name='Product Yearly 2222', Family='Yearly', isActive=true, CurrencyIsoCode='USD');

insert new List<Product2>{p1, p2};

Id pricebookId = Test.getStandardPricebookId();

PricebookEntry pbe1 = new PricebookEntry(Pricebook2id=pricebookId, Product2id=p1.ID, isActive=true, CurrencyIsoCode='USD', unitPrice=100);
PricebookEntry pbe2 = new PricebookEntry(Pricebook2id=pricebookId, Product2id=p2.ID, isActive=true, CurrencyIsoCode='USD', unitPrice=50);

insert pbe1;
insert pbe2;

List<PricebookEntry> pbes = [SELECT ID FROM PricebookEntry 
    WHERE Product2id IN (:p1.Id, :p2.Id) AND Pricebook2.isStandard = TRUE AND Pricebook2.isActive = TRUE AND CurrencyIsoCode = 'USD' AND isActive = TRUE];

System.assertEquals(2, pbes.size());

pbes.size() returns 0. I used the same query and I got results. What am I doing wrong?
