"""
E2E Test suite for Anthropic Messages API prompt caching across different providers.

Tests that prompt caching works correctly via litellm.anthropic.messages interface
by making actual API calls and validating usage metrics.

Per AWS docs (https://docs.aws.amazon.com/bedrock/latest/userguide/prompt-caching.html):
- Converse API uses: cachePoint: { type: "default" }
- InvokeModel API uses: cache_control: { type: "ephemeral" }
- Claude 3.7 Sonnet: GA, 1024 min tokens
- Claude 3.5 Haiku: GA, 2048 min tokens
