public function CommerceDiscountTest::testCommerceDiscountCompatibilityStrategies in Commerce Discount 7

Test discount compatibility strategies.

Currently implemented strategies include:

• any: discount is compatible with any other discount.
• except: discount is compatible with any discount except selected ones.
• only: discount is only compatible with selected ones.
• none: discount is not compatible with any other discount.

Compatibility is checked first to ensure that discounts already on an order are not incompatible with the discount being added. It is then checked to ensure the discount being added is not incompatible with any discount that has already been added to the order.
