library3.2.0pypypi✓ verified 87d ago

A Python library for mocking OpenSearch (Elasticsearch) operations in unit tests. Provides a lightweight in-memory mock that simulates OpenSearch behaviors without needing a real cluster. Current version: 3.2.0, requires Python >=3.10. Release cadence irregular.

Basic usage: use OpenMock as a context manager to mock OpenSearch client calls.

from openmock import OpenMock from opensearchpy import OpenSearch with OpenMock(): client = OpenSearch() # index a document client.index(index='my-index', body={'title': 'Test'}) # search result = client.search(index='my-index', body={'query': {'match_all': {}}}) print(result['hits']['hits'][0]['_source']['title']) # Output: Test

Debug

Known issues

breakingVersion 3.x dropped support for Python <3.10 and changed the import from 'openmock' (previously 'openmock.OpenMock' was sometimes imported incorrectly). Ensure your tests run on Python >=3.10.

fix

Upgrade Python to >=3.10 and use 'from openmock import OpenMock'.

affects: >=3.0.0

gotchaOpenMock does not persist state between different with-blocks or across separate test cases. Each context manager starts with a fresh mock cluster.

fix

Place all related OpenSearch operations within a single with block, or use the decorator form '@OpenMock()' for a whole test function.

affects: all

gotchaThe mock only supports a subset of OpenSearch APIs. Advanced features like snapshot/restore, scroll, or compatibility with specific OpenSearch plugins may not be available.

fix

Check the openmock documentation for the list of supported APIs. For unsupported operations, consider mocking manually or using a real test cluster.

affects: all
