From 7c3020c04ac30a53b74cc15def86b035052cc20b Mon Sep 17 00:00:00 2001 From: Julio Quinteros Pro Date: Sat, 14 Feb 2026 16:41:35 -0300 Subject: [PATCH] fix(test): update test_other_constraints_preserved for new schema filtering behavior MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PR #20813 changed the Anthropic schema filter to remove string and numeric constraints (minLength/maxLength, minimum/maximum) per Anthropic API requirements, but forgot to update the corresponding test. The new behavior (per Anthropic SDK): 1. Remove unsupported constraints from schema (Anthropic API doesn't support them) 2. Add constraint info to description field (e.g., "Note: minimum length: 1") **Changes:** - Updated test to expect constraints REMOVED from schema - Added assertions to verify constraints are added to description - Updated docstring to explain the new behavior **Testing:** - ✅ test_other_constraints_preserved now passes - ✅ All 4 tests in test_anthropic_structured_output.py pass **Related:** - Fixes test broken by PR #20813 - Aligns with Anthropic API requirements documented in commit 84934a7258 Co-Authored-By: Claude Sonnet 4.5 --- .../test_anthropic_structured_output.py | 25 ++++++++++--------- 1 file changed, 13 insertions(+), 12 deletions(-) diff --git a/tests/test_litellm/llms/anthropic/test_anthropic_structured_output.py b/tests/test_litellm/llms/anthropic/test_anthropic_structured_output.py index 521da6e8c6..705edeaf69 100644 --- a/tests/test_litellm/llms/anthropic/test_anthropic_structured_output.py +++ b/tests/test_litellm/llms/anthropic/test_anthropic_structured_output.py @@ -5,10 +5,9 @@ This test file verifies that Pydantic models with various constraints are properly converted to Anthropic-compatible JSON schemas.
