-Additionally, depending on the specific metric you're evaluating your test cases on, you may or may not require a `retrieval_context`, `expected_output`, `context`, `tools_called`, and/or `expected_tools` as additional parameters. For example, you won't need `expected_output`, `context`, `tools_called`, and `expected_tools` if you're just measuring answer relevancy, but if you're evaluating hallucination you'll have to provide `context` in order for `deepeval` to know what the **ground truth** is.

 With the exception of conversational metrics, which are metrics to evaluate conversations instead of individual LLM responses, you can use any LLM evaluation metric `deepeval` offers to evaluate an `LLMTestCase`.
