From 2d28c5a0561a829ec0749bcb45597438928cb908 Mon Sep 17 00:00:00 2001 From: shin-bot-litellm Date: Sat, 31 Jan 2026 23:05:22 +0000 Subject: [PATCH] litellm_fix_mapped_tests_core: clear client cache and fix isinstance checks ## Problem Tests using mocked HTTP clients were hitting real APIs because: 1. HTTP client cache was returning previously cached real clients 2. isinstance checks failed due to module identity issues from sys.path ### Tests affected: - test_send_email_missing_api_key - test_send_email_multiple_recipients (resend & sendgrid) - test_search_uses_registry_credentials - test_vector_store_create_with_simple_provider_name - test_vector_store_create_with_provider_api_type - test_vector_store_create_with_ragflow_provider - test_image_edit_merges_headers_and_extra_headers - test_retrieve_container_basic (container API tests) ## Solution 1. Add clear_client_cache fixture (autouse=True) to clear litellm.in_memory_llm_clients_cache before each test 2. Fix isinstance checks to use type name comparison (avoids module identity issues from sys.path.insert) ## Why not disable_aiohttp_transport The default transport is aiohttp, so tests should work with it. Clearing the cache ensures mocks are used instead of cached real clients. ## Regression PR #19829 (commit f95572e3ed) added @respx.mock but cached clients from earlier tests were being reused, bypassing the mocks. --- .../containers/test_container_api.py | 15 +++++++++++++++ .../send_emails/test_resend_email.py | 16 ++++++++++++++++ .../send_emails/test_sendgrid_email.py | 15 +++++++++++++++ tests/test_litellm/test_main.py | 14 ++++++++++++++ ...test_vector_store_create_provider_logic.py | 19 ++++++++++--------- .../test_vector_store_registry.py | 14 ++++++++++++++ 6 files changed, 84 insertions(+), 9 deletions(-) diff --git a/tests/test_litellm/containers/test_container_api.py b/tests/test_litellm/containers/test_container_api.py index f489447ca99..ddfe7c9ef14 100644 --- a/tests/test_litellm/containers/test_container_api.py +++ b/tests/test_litellm/containers/test_container_api.py @@ -32,6 +32,21 @@ from litellm.types.containers.main import ( ) +@pytest.fixture(autouse=True) +def clear_client_cache(): + """ + Clear the HTTP client cache before each test to ensure mocks are used. + This prevents cached real clients from being reused across tests. + """ + cache = getattr(litellm, "in_memory_llm_clients_cache", None) + if cache is not None: + cache.flush_cache() + yield + #
