Flask API 를 테스트하기 위한 아이디어

test_get_collection.py

# 실제 API
def get_collections(serializer):
    collections = orm.foo()
    paging = orm.bar()
    return serializer.serialize(items=collections, paging=paging)

# 테스트
def test_serializer_get_collections():
    collections = fixture_collections()
    paging = fixture_paging()
    serializer = ListSerializer()
    result = serializer.serialize(items=collections, paging=paging)
    assert_equal(len(result['items']), 3)
    assert_nil(len(result['paging']['next']))

def test_api_get_collections():
    serializer = StubListSerializer()
    get_collections(serializer)
    assert_equal(len(serializer.executions['serialize']), 1)

class StubListSerializer(object):
    executions = {}
    def serialize(items, paging):
        executions.setdefault('serialize', [])
        executions['serialize'].append((items, paging))
