Test subclasses must implement the ``embeddings_class`` property to specify the
|
|
embeddings model to be tested. You can also override the
|
|
``embedding_model_params`` property to specify initialization parameters.
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
from typing import Type
|
|
|
|
from langchain_tests.integration_tests import EmbeddingsIntegrationTests
