From de3950c8634d1c891969b0fce9900139ec8488da Mon Sep 17 00:00:00 2001 From: s2005 Date: Sun, 15 Feb 2026 09:58:18 +0100 Subject: [PATCH 1/6] test: add macOS integration tests (bash shell) Note: Tests use 'bash' shell directly instead of 'bash_auto' because TestCLIServer has a bug where bash shell config is expected to have wslConfig, but bash now properly uses Unix paths without wslConfig. This reveals an existing issue in CLIServer.executeShellCommand that needs to be fixed separately. Tests cover: - Unix path validation (/Users, /tmp, relative paths, Windows paths rejected) - macOS command blocking (rm -rf /, dd, mkfs, diskutil, safe commands) - Working directory restrictions (allowed vs disallowed paths) - Operator blocking (&& chaining allowed/disabled) - Initial directory support --- tests/integration/macosBashAuto.test.ts | 206 ++++++++++++++++++++++++ 1 file changed, 206 insertions(+) create mode 100644 tests/integration/macosBashAuto.test.ts diff --git a/tests/integration/macosBashAuto.test.ts b/tests/integration/macosBashAuto.test.ts new file mode 100644 index 0000000..8fa5089 --- /dev/null +++ b/tests/integration/macosBashAuto.test.ts @@ -0,0 +1,206 @@ +import { describe, test, expect, beforeAll } from '@jest/globals';
