From fd1237e9af02893436b334d4b8e01eec33befd5d Mon Sep 17 00:00:00 2001 From: Julio Quinteros Pro Date: Tue, 17 Feb 2026 19:57:32 -0300 Subject: [PATCH] fix(token-counter): fix test isolation and encode() return type normalization Two independent fixes for test_token_counter.py failures in CI: 1. test_disable_hf_tokenizer_download leaked litellm.disable_hf_tokenizer_download=True because pytest.MonkeyPatch() was never undone. The setting persisted into the alphabetically-subsequent test_llama2/3_tokenizer_api_failure tests, causing _select_tokenizer_helper to short-circuit before calling from_pretrained. Fix: wrap the test body in try/finally and call monkeypatch.undo(). 2. encode() returns a HuggingFace Encoding object when the HF tokenizer loads, but falls back to returning a plain List[int] (tiktoken) when the model hub is unreachable. test_encoding_and_decoding called .ids on the result, which raises AttributeError when the list-based fallback is active. Fix: normalize encode() to always return List[int] by extracting .ids when present, and remove the now-unnecessary .ids access in the test.
