Each helper method can now be tested independently:
def test_get_promotion_data():
service = ObjServiceApi()
promo = service._get_promotion_data("TEST-001")
assert isinstance(promo, dict)
assert "promotion_name" in promo
def test_get_warranty_data():
service = ObjServiceApi()
warranty = service._get_warranty_data("TEST-001")
assert "warranty_code" in warranty
assert warranty["warranty_code"] in [0, 1, 2, 3]
def test_calculate_pricing():
service = ObjServiceApi()
promo = {"promotion_price": 799.00, "original_price": 999.00}
pricing = service._calculate_pricing(999.00, promo)
assert pricing["price"] == "799.00"
assert pricing["compare_at_price"] == "999.00"
def test_build_options_bedding():
service = ObjServiceApi()
options = service._build_options_for_product(1, {})
assert len(options) == 2
assert options[0]["name"] == "Width"
assert len(options[0]["values"]) == 5
def test_build_all_variants_bedding():
service = ObjServiceApi()
product_data = {"total_price": 999.00, "volumetric": 0.5}
promo_data = {"promotion_name": "", "original_price": 999.00}
warranty_data = {"extended_warranty": ""}
variants = service._build_all_variants(
"BED-001",
1, # Bedding
product_data,
promo_data,
warranty_data
)
assert len(variants) == 5 # 5 bed sizes
assert variants[0]["option1"] == "Single"
assert variants[4]["option1"] == "King"
