From e329d52c348ea551e7386e054f6f6933c9a1d8ed Mon Sep 17 00:00:00 2001 From: Codeflash Bot Date: Thu, 2 Apr 2026 17:44:46 +0000 Subject: [PATCH 1/2] fix: Improve error messaging for files excluded from Vitest coverage ## Problem When a file is excluded from coverage by vitest.config.ts (e.g., via `coverage.exclude: ["src/agents/**"]`), Codeflash reports misleading "Test coverage is 0.0%" messages even though tests run successfully. This happens because: - Vitest doesn't include excluded files in coverage-final.json - Codeflash detects this (status = NOT_FOUND) but shows generic 0% message - Users don't know the file is excluded from coverage collection ## Solution Detect when coverage status is NOT_FOUND and provide a clear, actionable error message explaining: 1. No coverage data was found for the file 2. It may be excluded by test framework configuration 3. Where to check (coverage.exclude in vitest.config.ts, etc.) ## Changes - function_optimizer.py: Check CoverageStatus.NOT_FOUND before reporting 0% - Added clear warning log and user-facing error message - New test file: test_vitest_coverage_exclusions.py ## Testing - All existing JavaScript tests pass - New tests verify NOT_FOUND status is returned correctly - Manual verification with openclaw logs (trace: 2a84fe6b-9871-4916-96da-bdd79bca508a) Fixes #BUG-1 (from autoresearch:debug workflow) Trace IDs affected: All 10 log files showing 0% coverage in /workspace/logs Co-Authored-By: Claude Sonnet 4.5 --- codeflash/languages/function_optimizer.py | 19 +++ .../test_vitest_coverage_exclusions.py | 125 ++++++++++++++++++ 2 files changed, 144 insertions(+) create mode 100644 tests/languages/javascript/test_vitest_coverage_exclusions.py diff --git a/codeflash/languages/function_optimizer.py b/codeflash/languages/function_optimizer.py index 09819feb2..378b1a15f 100644 --- a/codeflash/languages/function_optimizer.py +++ b/codeflash/languages/function_optimizer.py @@ -2787,6 +2787,25 @@ def establish_original_code_baseline( did_pass_all_tests = all(result.did_pass for result in behavioral_results) if not did_pass_all_tests: return Failure("Tests failed to pass for the original code.") + + # Check if coverage data was not found (file excluded from coverage) + from codeflash.models.models import CoverageStatus + + if coverage_results and coverage_results.status == CoverageStatus.NOT_FOUND: + # File was not found in coverage data - likely excluded by test framework config + logger.warning( + f"No coverage data found for {self.function_to_optimize.source_file_path}.
