From 3f49ed25c4544ef92c8c02b07f5c1eaf74fd56e3 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 26 Nov 2025 03:05:21 +0000 Subject: [PATCH 1/3] test: add comprehensive tests for logParser.worker.js MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements Week 1 priority testing for the Web Worker parsing logic. Coverage improvements: - Worker: 0% β†’ 100% statement coverage, 95.45% branch coverage - Overall: 85.32% β†’ 91.09% statement coverage - Added 33 new test cases Test coverage includes: - Keyword-based value extraction - Regex-based value extraction - Step number extraction (custom keywords, case-insensitive) - Scientific notation and negative numbers - Metric naming (derived from name/keyword/regex) - Error handling (empty content, invalid regex, NaN values) - Edge cases (special characters, large numbers, mixed line endings) - Real-world log formats (PyTorch, TensorFlow, JSON, wandb) - Performance scenarios (1000+ data points) This addresses the critical gap in testing the core parsing engine that processes all user-uploaded log files. --- .../__tests__/logParser.worker.test.js | 819 ++++++++++++++++++ 1 file changed, 819 insertions(+) create mode 100644 src/workers/__tests__/logParser.worker.test.js diff --git a/src/workers/__tests__/logParser.worker.test.js b/src/workers/__tests__/logParser.worker.test.js new file mode 100644 index 0000000..cbec097 --- /dev/null +++ b/src/workers/__tests__/logParser.worker.test.js @@ -0,0 +1,819 @@ +import { describe, it, expect, vi, beforeEach, afterEach } from 'vitest';
