Using the MockRegistryApi

mockregistry.py

# In unit tests =====================================

from kafkit.registry.sansio import MockRegistryApi

# The Avro schema that you'll be testing with
schema = {}

# The MockRegistryApi works just like the RegistryApi, but doesn't
# do any network requests.
registryclient = MockRegistryApi()

# Insert the schema you know you're using into the client's
# cache. The `1` is just the unique ID that the Confluent Schema
# Registry server would have assigned to it.
registryclient.schemas.insert(schema, 1)

# In the application code =============================
# Now you can pass this registryclient into the code being
# tested and it will work without any network I/O.

# The serializer can now use this registry. When it does
serializer = await Serializer.register(
    registry=client,
    schema=schema)
