Welcome to labgrid
Labgrid is a embedded board control python library with a focus on testing, development and general automation. It includes a remote control layer to control boards connected to other hosts.
The idea behind labgrid is to create an abstraction of the hardware control layer needed for testing of embedded systems, automatic software installation and automation during development. Labgrid itself is not a testing framework, but is intended to be combined with pytest (and additional pytest plugins). Please see Design Decisions for more background information.
It currently supports:
- pytest plugin to write tests for embedded systems connecting serial console or SSH
- remote client-exporter-coordinator infrastructure to make boards available from different computers on a network
- power/reset management via drivers for power switches or onewire PIOs
- upload of binaries via USB: imxusbloader/mxsusbloader (bootloader) or fastboot (kernel)
- functions to control external services such as emulated USB-Sticks and the hawkBit deployment service
While labgrid is currently used for daily development on embedded boards and for automated testing, several planned features are not yet implemented and the APIs may be changed as more use-cases appear. We appreciate code contributions and feedback on using labgrid on other environments (see Contributing for details). Please consider contacting us (via a GitHub issue) before starting larger changes, so we can discuss design trade-offs early and avoid redundant work. You can also look at Ideas for enhancements which are not yet implemented.
Work on labgrid started at Pengutronix in late 2016 and is currently in active use and development.
Clone the git repository:
$ git clone https://github.com/labgrid-project/labgrid
Create and activate a virtualenv for labgrid:
$ virtualenv -p python3 venv $ source venv/bin/activate
Install labgrid into the virtualenv:
$ python setup.py install
Tests can now run via:
$ python -m pytest --lg-env <config>
