Hi all -- In unit tests, is there an example for mocking partitions that use resources? More details in :thread:

Untitled.py

Here is my pseudocode example. It seems like `create_partitions()` is called upon the file instantiation, so it's not possible to mock the partition or the underlying external resource. Thoughts?

Hi Juan - that’s accurate. Building a PartitionsDefinition using resources isn’t a typical Dagster pattern. If you want to be able to mock this out, you’d need to create a function that returns your PartitionsDefinition and asset. Or you could use mock.patch.
