# BeamWeaver Conformance Tests



BeamWeaver conformance tests are shared ExUnit cases translated from the

behavioral shape of LangChain standard tests. They are intentionally

BeamWeaver-native: providers and adapters implement behaviours, then shared

cases exercise them through public Elixir wrappers.



Implemented shared cases include:



- `BeamWeaver.TestSupport.Conformance.ChatModelCase`

- `BeamWeaver.TestSupport.Conformance.EmbeddingModelCase`

- `BeamWeaver.TestSupport.Conformance.ToolCase`

- `BeamWeaver.TestSupport.Conformance.LLMCase`

- `BeamWeaver.TestSupport.Conformance.CacheCase`

- `BeamWeaver.TestSupport.Conformance.ChatHistoryCase`

- `BeamWeaver.TestSupport.Conformance.DocumentLoaderCase`

- `BeamWeaver.TestSupport.Conformance.TextSplitterCase`

- `BeamWeaver.TestSupport.Conformance.VectorStoreCase`

- `BeamWeaver.TestSupport.Conformance.RecordManagerCase`

- `BeamWeaver.TestSupport.Conformance.IndexingCase`

- `BeamWeaver.TestSupport.Conformance.RetrieverCase`

- `BeamWeaver.TestSupport.Conformance.AgentCase`



Example:



```elixir

defmodule MyProvider.ChatModelTest do

  use BeamWeaver.TestSupport.Conformance.ChatModelCase,

    subject: %BeamWeaver.TestSupport.Conformance.Subject{

      module: {MyProvider.ChatModel, model: "example"}

    }

end

```



Runtime code should depend on behaviours and adapters, not the test support

modules. Conformance cases live under `support/conformance` and are test-only.



Run:



```bash

mix test test/beam_weaver/conformance

mix test test/beam_weaver/checkpoint/conformance_test.exs

mix test test/beam_weaver/memory/conformance_test.exs

```
