Notes
langchain upgrade included a few deprecations of functions we were using
Mocking in our langchain tests needed to be addressed, as the upgraded types were causing compilation errors. Mocking of RetrievalQAChain in particular causes problems, because we are mocking both a static factory method on the class, and methods on an object instance of the class. However, I see that RetrievalQAChain is no longer the recommended way to achieve this call chain: instead we are guided to use the LangChain Expression Language to construct our chains. We will tackle that change in a separate issue, so here I address only the current mock setup.
