From 6d33b62d37fab90e85850a3e2e1ce6e8cd1d8293 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 8 Dec 2025 18:14:51 +0000 Subject: [PATCH 4/4] fix: switch test runner to Deno with raw JS assertions - Update test files to use raw JavaScript assertion functions instead of Deno.assertEquals (which is not on Deno object) - Update npm test script to specify explicit test file paths - Update CI workflow to run Deno tests correctly - All 34 tests pass with Deno --- .github/workflows/ci.yml | 24 +++++++++--------- package.json | 2 +- test/Tea_Cmd_test.res | 55 ++++++++++++++++++++++------------------
