Pytest Twister harness

Installation

If you plan to use this plugin with Twister, then you don't need to install it separately by pip. When Twister uses this plugin for pytest tests, it updates PYTHONPATH variable, and then extends pytest command by -p twister_harness.plugin argument.

Usage

Run exemplary test shell application by Twister:

cd ${ZEPHYR_BASE}

# native_sim & QEMU
./scripts/twister -p native_sim -p qemu_x86 -T samples/subsys/testsuite/pytest/shell

# hardware
./scripts/twister -p nrf52840dk/nrf52840 --device-testing --device-serial /dev/ttyACM0 -T samples/subsys/testsuite/pytest/shell

or build shell application by west and call pytest directly:

export PYTHONPATH=${ZEPHYR_BASE}/scripts/pylib/pytest-twister-harness/src:${PYTHONPATH}

cd ${ZEPHYR_BASE}/samples/subsys/testsuite/pytest/shell

# native_sim
west build -p -b native_sim -- -DCONFIG_NATIVE_UART_0_ON_STDINOUT=y
pytest --twister-harness --device-type=native --build-dir=build -p twister_harness.plugin

# QEMU
west build -p -b qemu_x86 -- -DQEMU_PIPE=qemu-fifo
pytest --twister-harness --device-type=qemu --build-dir=build -p twister_harness.plugin

# hardware
west build -p -b nrf52840dk/nrf52840
pytest --twister-harness --device-type=hardware --device-serial=/dev/ttyACM0 --build-dir=build -p twister_harness.plugin
