// MISSION BRIEF

Your Mission

DeepEval's pitch is simple: evaluate LLM outputs with the same workflow you already use for code, pytest. You build an LLMTestCase, attach metrics with thresholds, and assert_test makes quality a red/green test result.

This quiz covers the core authoring API: test cases, metric thresholds, and how the CLI wraps pytest. Speed bonus active.

// FIRST CONTACT

Battle teaser

In DeepEval, an LLMTestCase is:

  1. AA YAML file describing a conversation
  2. BA subclass of unittest.TestCase that calls the OpenAI API
  3. CA container for one interaction: input, actual_output, and optionally expected_output, retrieval_context, or context, the unit that metrics evaluate
  4. DA wrapper that retries flaky LLM calls
Answers, scoring, hints, and the full battle stay sealed.
