In DeepEval's latest release, we are introducing a slight change in how a conversation is evaluated.

Previously we assumed a conversation as as a list of LLMTestCases, which might necessarily be the case. Now a conversational test case is made up of a list of Turns instead, which follows OpenAI's standard messages format:

from deepeval.test_case import Turn

turns = [Turn(role="user", content="...")]
