This project, inspired by [usbtest](http://www.linux-usb.org/usbtest/) and
|
||
|
|
the linux usb gadget zero driver is used for regression testing changes to the
|
||
|
|
libopencm3 usb stack.
|
||
|
|
|
||
|
|
The firmware itself is meant to be portable to any supported hardware, and then
|
||
|
|
identical unit test code is run against all platforms. This project can and
|
||
|
|
should be built for multiple devices.
|
||
|
|
|
||
|
|
## Requirements:
|
||
|
|
* [pyusb](https://walac.github.io/pyusb/) for running the tests.
|
||
|
|
* [OpenOCD](http://openocd.org/) >= 0.9 for automated flashing of specific boards
|
||
|
|
* python3 for running the tests at the command line.
|
||
|
|
* unittest-xml-reporting, only if running in CI mode. XX
|
||
|
|
|
||
|
|
### Building the device firmware
|
||
|
|
There are Makefile.xxxxx files for all the currently tested targets.
|
||
|
|
```
|
||
|
|
make -f Makefile.stm32f4disco clean all V=1
|
||
|
|
```
|
||
|
|
The ```V=1``` is optional, and turns on verbose mode, which can be useful if
|
||
|
|
things don't work. This will give you a .elf file you can program using your
|
||
|
|
own toolchain, but if you have a functional OpenOCD installed, then...
|
||
|
|
```
|
||
|
|
make -f Makefile.stm32f4disco clean all flash
|
||
|
|
```
|
||
|
|
Will handle flashing as well.
|
||
|
|
|
||
|
|
### Setting up the test runner (using python virtual environments)
|
||
|
|
```
|
||
|
|
pyvenv .env # ensures a python3 virtual env
|
||
|
|
. .env/bin/activate
|
||
|
|
pip install pyusb
|
||
|
|
```
|
||
|
|
|
||
|
|
If you have multiple test boards connected, have a look at opencd.common.cfg
|
||
|
|
for some tips on selectively matching the right board. For people with just
|
||
|
|
a single matching board, you don't need to do anything.
|
||
|
|
|
||
|
|
Tests marked as @unittest.skip are either for functionality that is known to be
|
||
|
|
broken, and are awaiting code fixes, or are long running performance tests
|
||
|
|
|
||
|
|
### Access rights
|
||
|
|
On some systems (most linux systems) you probably won't have access to the
|
||
|
|
usb vendor id being used/hijacked by the test cases. See 70-libopencm3.rules
|
||
|
|
for installation instructions, or, if you have your own system, grant yourself
|
||
|
|
access to the usb vid: 0xcafe
|
||
|
|
|
||
|
|
## Running the tests
|
||
|
|
Below is an example of running the full suite of tests from the command line.
|
||
|
|
The argument specifies the serial number to look for in the usb gadget, if
|
||
|
|
you have more than one. No argument will the tests against all
|
||
|
|
gadget-zero's found.
|
||
|
|
```
|
||
|
|
$ python test_gadget0.py
|
||
|
|
Running tests for DUT: stm32f072disco
|
||
|
|
.........ss................
|
||
|
|
----------------------------------------------------------------------
|
||
|
|
Ran 27 tests in 0.388s
|
||
|
|
|
||
|
|
OK (skipped=2)
|
||
|
|
```
|
||
|
|
|
||
|
|
To be even more brutal, run this in a shell loop.
|
||
|
|
```
|
||
|
|
$ while true; do python test_gadget0.py -d stm32f072disco; done
|
||
|
|
```
|
||
|
|
|
||
|
|
You can also run individual tests, or individual sets of tests, see the [unittest documentation](https://docs.python.org/3/library/unittest.html) for more information.
|
||
|
|
|
||
|
|
Many development environments, such as [PyCharm](https://www.jetbrains.com/pycharm/) can
|
||
|
|
also be used to edit and run the tests, in whole or individually, with a nice visual test runner.
