"""
|
|
This test checks the functionality of the 'chat' method in the App class with respect to the chat history
|
|
memory.
|
|
The 'chat' method is called twice. The first call initializes the chat history memory.
|
|
The second call is expected to use the chat history from the first call.
|
|
|
|
Key assumptions tested:
|
|
- After the first call, 'memory.chat_memory.add_user_message' and 'memory.chat_memory.add_ai_message' are
|
|
called with correct arguments, adding the correct chat history.
|
|
- During the second call, the 'chat' method uses the chat history from the first call.
|
|
|
|
The test isolates the 'chat' method behavior by mocking out 'retrieve_from_database', 'get_answer_from_llm' and
|
|
'memory' methods.
