From 62cbeb63678e75f0975e936ad2a88c7913468176 Mon Sep 17 00:00:00 2001 From: Teknium <127238744+teknium1@users.noreply.github.com> Date: Mon, 20 Apr 2026 23:20:33 -0700 Subject: [PATCH] =?UTF-8?q?test:=20stop=20testing=20mutable=20data=20?= =?UTF-8?q?=E2=80=94=20convert=20change-detectors=20to=20invariants=20(#13?= =?UTF-8?q?363)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Catalog snapshots, config version literals, and enumeration counts are data that changes as designed. Tests that assert on those values add no behavioral coverage — they just break CI on every routine update and cost engineering time to 'fix.' Replace with invariants where one exists, delete where none does. Deleted (pure snapshots): - TestMinimaxModelCatalog (3 tests): 'MiniMax-M2.7 in models' et al - TestGeminiModelCatalog: 'gemini-2.5-pro in models', 'gemini-3.x in models' - test_browser_camofox_state::test_config_version_matches_current_schema (docstring literally said it would break on unrelated bumps) Relaxed (keep plumbing check, drop snapshot): - Xiaomi / Arcee / Kimi moonshot / Kimi coding / HuggingFace static lists: now assert 'provider exists and has >= 1 entry' instead of specific names - HuggingFace main/models.py consistency test: drop 'len >= 6' floor Dynamicized (follow source, not a literal): - 3x test_config.py migration tests: raw['_config_version'] == DEFAULT_CONFIG['_config_version'] instead of hardcoded 21 Fixed stale tests against intentional behavior changes: - test_insights::test_gateway_format_hides_cost: name matches new behavior (no dollar figures); remove contradicting '$' in text assertion - test_config::prefers_api_then_url_then_base_url: flipped per PR #9332; rename + update to base_url > url > api - test_anthropic_adapter: relax assert_called_once() (xdist-flaky) to assert called — contract is 'credential flowed through' - test_interrupt_propagation: add provider/model/_base_url to bare-agent fixture so the stale-timeout code path resolves Fixed stale integration tests against opt-in plugin gate: - transform_tool_result + transform_terminal_output: write plugins.enabled allow-list to config.yaml and reset the plugin manager singleton Source fix (real consistency invariant): - agent/model_metadata.py: add moonshotai/Kimi-K2.6 context length (262144, same as K2.5). test_model_metadata_has_context_lengths was correctly catching the gap. Policy: - AGENTS.md Testing section: new subsection 'Don't write change-detector tests' with do/don't examples. Reviewers should reject catalog-snapshot assertions in new tests.
