From fdc37efde7153b6665a65db6303dc52a0cbb3af3 Mon Sep 17 00:00:00 2001 From: czlonkowski Date: Thu, 26 Mar 2026 23:41:06 +0100 Subject: [PATCH] refactor: streamline test suite - cut 33 files, enable parallel execution (11.9x speedup) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Remove duplicate, low-value, and fragmented test files while preserving all meaningful coverage. Enable parallel test execution and remove the entire benchmark infrastructure. Key changes: - Consolidate workflow-validator tests (13 files -> 3) - Consolidate config-validator tests (9 files -> 3) - Consolidate telemetry tests (11 files -> 6) - Merge AI validator tests (2 files -> 1) - Remove example/demo test files, mock-testing files, and already-skipped tests - Remove benchmark infrastructure (10 files, CI workflow, 4 npm scripts) - Enable parallel test execution (remove singleThread: true) - Remove retry:2 that was masking flaky tests - Slim CI publish-results job Results: 224 -> 191 test files, 4690 -> 4303 tests, 121K -> 106K lines Local runtime: 319s -> 27s (11.9x speedup) Conceived by Romuald CzΕ‚onkowski -
