From e0b95835da21810bf1e345c3a528330f61e4a5b0 Mon Sep 17 00:00:00 2001 From: AnExiledDev Date: Fri, 27 Feb 2026 06:46:37 +0000 Subject: [PATCH] Add pytest suite for 6 critical plugin scripts (241 tests) Security guards, workspace scope enforcement, readonly bash guard, and agent redirect logic had zero test coverage. This adds pytest tests for the pure functions in each script, covering all regex patterns, edge cases, bypass vectors, and false positive checks. --- .devcontainer/CHANGELOG.md | 12 + package.json | 2 + tests/__init__.py | 0 tests/conftest.py | 52 +++ tests/plugins/__init__.py | 0 tests/plugins/test_block_dangerous.py | 255 ++++++++++++++ tests/plugins/test_guard_protected.py | 223 ++++++++++++ tests/plugins/test_guard_protected_bash.py | 221 ++++++++++++ tests/plugins/test_guard_readonly_bash.py | 319 ++++++++++++++++++ tests/plugins/test_guard_workspace_scope.py | 226 +++++++++++++ tests/plugins/test_redirect_builtin_agents.py | 174 ++++++++++ 11 files changed, 1484 insertions(+) create mode 100644 tests/__init__.py create mode 100644 tests/conftest.py create mode 100644 tests/plugins/__init__.py create mode 100644 tests/plugins/test_block_dangerous.py create mode 100644 tests/plugins/test_guard_protected.py create mode 100644 tests/plugins/test_guard_protected_bash.py create mode 100644 tests/plugins/test_guard_readonly_bash.py create mode 100644 tests/plugins/test_guard_workspace_scope.py create mode 100644 tests/plugins/test_redirect_builtin_agents.py diff --git a/.devcontainer/CHANGELOG.md b/.devcontainer/CHANGELOG.md index cc6e83c..6024503 100644 --- a/.devcontainer/CHANGELOG.md +++ b/.devcontainer/CHANGELOG.md @@ -2,6 +2,18 @@ ## [Unreleased] +### Added + +#### Testing +- **Plugin test suite** — 241 pytest tests covering 6 critical plugin scripts that previously had zero tests: + -
