From 14f937cf8a2762ef0ae0c103bb3c08f6a962d4b3 Mon Sep 17 00:00:00 2001 From: torlando-tech Date: Mon, 4 May 2026 14:50:16 -0400 Subject: [PATCH] Add native pyxis test suite + CI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Standalone C++ tests of pyxis-unique code (BLE fragmenter/reassembler, peer manager, GATT op queue, LXST ring buffers, audio filters, HDLC framing) plus Python tests of the patch_nimble.py build script. Each C++ test is compiled directly by clang++/g++ with shims in tests/native/ (Bytes.h, Log.h, Utilities/OS.h) so pyxis sources can build without microReticulum's full Arduino/MsgPack dep tree. A pytest wrapper per test compiles, runs, and parses the summary line — the whole suite is one command: `pytest tests/build_scripts tests/native -v`. Total: 13 pytest tests, ~72 underlying C++ assertions, 3.4s. Surfaced an HPF-formula bug in lxst_audio (mirrored upstream in LXST-kt/native_audio_filters.cpp) — filed as LXST-kt#13 and tracked in the corresponding test with a TODO link. CI workflow runs the pyxis pytest suite plus the clean-passing microReticulum native17 unit tests (94/114 of the existing fork test/* suites) on push and PR. --- .github/workflows/test.yml | 71 +++++ tests/README.md | 54 ++++ tests/build_scripts/test_patch_nimble.py | 253 ++++++++++++++++ tests/native/Bytes.h | 5 + tests/native/Log.h | 35 +++ tests/native/Utilities/OS.h | 43 +++ tests/native/bytes_shim.h | 80 ++++++ tests/native/test_audio_filters.cpp | 261 +++++++++++++++++ tests/native/test_audio_filters.py | 54 ++++ tests/native/test_ble_fragmenter.cpp | 312 ++++++++++++++++++++ tests/native/test_ble_fragmenter.py | 60 ++++ tests/native/test_ble_operation_queue.cpp | 333 ++++++++++++++++++++++ tests/native/test_ble_operation_queue.py | 54 ++++ tests/native/test_ble_peer_manager.cpp | 283 ++++++++++++++++++ tests/native/test_ble_peer_manager.py | 54 ++++ tests/native/test_hdlc.cpp | 201 +++++++++++++ tests/native/test_hdlc.py | 66 +++++ tests/native/test_ring_buffers.cpp | 302 ++++++++++++++++++++ tests/native/test_ring_buffers.py | 56 ++++ 19 files changed, 2577 insertions(+) create mode 100644 .github/workflows/test.yml create mode 100644 tests/README.md create mode 100644 tests/build_scripts/test_patch_nimble.py create mode 100644 tests/native/Bytes.h create mode 100644 tests/native/Log.h create mode 100644 tests/native/Utilities/OS.h create mode 100644 tests/native/bytes_shim.h create mode 100644 tests/native/test_audio_filters.cpp create mode 100644 tests/native/test_audio_filters.py create mode 100644 tests/native/test_ble_fragmenter.cpp create mode 100644 tests/native/test_ble_fragmenter.py create mode 100644 tests/native/test_ble_operation_queue.cpp create mode 100644 tests/native/test_ble_operation_queue.py create mode 100644 tests/native/test_ble_peer_manager.cpp create mode 100644 tests/native/test_ble_peer_manager.py create mode 100644 tests/native/test_hdlc.cpp create mode 100644 tests/native/test_hdlc.py create mode 100644 tests/native/test_ring_buffers.cpp create mode 100644 tests/native/test_ring_buffers.py diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml new file mode 100644 index 00000000..b1646ba0 --- /dev/null +++ b/.github/workflows/test.yml @@ -0,0 +1,71 @@ +name: Test + +on: + push: + branches: [main] + pull_request: + branches: [main] + +jobs: + pyxis-pytest: + name: Pyxis pytest suite (build_scripts + native) + runs-on: ubuntu-latest + steps: + - name: Checkout + uses: actions/checkout@v4 + with: + submodules: recursive + + - name: Set up Python + uses: actions/setup-python@v5 + with: + python-version: '3.11' + + - name: Install pytest + run: pip install pytest + + - name: Run pytest + run: pytest tests/build_scripts tests/native -v + + microreticulum-native: + name: microReticulum native unit tests (PlatformIO native17) + runs-on: ubuntu-latest + steps: + - name: Checkout + uses: actions/checkout@v4 + with: + submodules: recursive + + - name: Set up Python + uses: actions/setup-python@v5 + with: + python-version: '3.11' + + - name: Cache PlatformIO + uses: actions/cache@v4 + with: + path: | + ~/.cache/pip + ~/.platformio/.cache + key: ${{ runner.os }}-pio-mrn + + - name: Install PlatformIO + run: pip install --upgrade platformio + + # Run only suites that build cleanly under native17 in the fork. + # Erroring suites (test_ble, test_tdeck, test_lxmf, test_ratchets, etc.) + # are tracked separately — see pyxis MEMORY.md. + - name: Run native17 tests + working-directory: deps/microReticulum + run: | + pio test -e native17 -f test_os + pio test -e native17 -f test_bytes + pio test -e native17 -f test_msgpack + pio test -e native17 -f test_crypto + pio test -e native17 -f test_filesystem + pio test -e native17 -f test_objects + pio test -e native17 -f test_general + pio test -e native17 -f test_reference + pio test -e native17 -f test_example + pio test -e native17 -f test_collections + pio test -e native17 -f test_interop diff --git a/tests/README.md b/tests/README.md new file mode 100644 index 00000000..ee293c40 --- /dev/null +++ b/tests/README.md @@ -0,0 +1,54 @@ +# Pyxis Tests + +Three test surfaces, each runnable independently. + +## 1.
