Testing Django Rest Framework Serializers with pytest

Question

I could use pytest for testing models and views in my django project. Is it possible to use pytest for DRF serializers as well, appreciate pointers to samples.

Answer 1

The following works:

def test_foo_serializer():
    from app.models import Model
    from app.serializers import ModelSerializer

    serializer = ModelSerializer()
    f = serializer.fields['field_name']
    obj = Model()

    assert f.to_representation(obj) == '0.00'
    obj.prop = 123
    assert f.to_representation(obj) == '1.23'
