Answer 1

you have to make the pricebook entry Active In the part

    PricebookEntry pbe = new PricebookEntry();
    pbe.Pricebook2Id=Test.getStandardPricebookId();
    pbe.Product2Id=p1.id;
    pbe.UnitPrice=3000;
    pbe.UseStandardPrice=false;
    pbe.isActive=true;//Add this line
    insert pbe;

Answer 2

You need to set the IsActive flag to true on your Pricebook2, PricebookEntry, and Product2 records. The default value is to make these records inactive.
