python3-langchain-tests-0.3.19-1.lbn36.noarch

langchain-tests This is a testing library for LangChain integrations. It contains the base classes for a standard set of tests. Installation We encourage pinning your version to a specific version in order to avoid breaking your CI when we publish new tests. We recommend upgrading to the latest version periodically to make sure you have the latest tests. Not pinning your version will ensure you always have the latest tests, but it may also break your CI if we introduce tests that your integration doesn't pass. Pip: ```bash pip install -U langchain-tests ```

Poetry: ```bash poetry add langchain-tests ```

Usage To add standard tests to an integration package's e.g. ChatModel, you need to create

A unit test class that inherits from ChatModelUnitTests An integration test class that inherits from ChatModelIntegrationTests
