-title: PyAGL
----
-
-# 0. Intro
-## Main purpose
-PyAGL was written to be used as a testing framework replacing the Lua afb-test one,
-however the modules are written in a way that could be used as standalone utilities to query
-and evaluate apis and verbs from the App Framework Binder services in AGL.
-
-## High level overview
-Python compatibility: **Python 3.8 preferred**, **should** be compatible with **3.6**
-
-Initial development PyAGL was done with Python **3.6** in mind, heavily using f-strings and a few typings. As of writing this
-documentation(June 3rd 2021), current stable AGL version is Koi 11.0.2 which has Python 3.8, and further development is
-done using 3.8 and 3.9 runtimes although **no** version-specific features are used from later versions;
-features **used** are kept within features offered by Python **3.8**.
-
-The test suite is written in a relatively standard way of extending **pytest** with a couple tweaks
-tailored to Jenkins CI and LAVA for AGL with regards to output and timings/timeouts, and these tweaks
-are enabled by running `pytest -L` in order to enable LAVA logging behavior.
-
-The way PyAGL works could be summarized in several bullets below:
-
-* `websockets` package is used to communicate to the services, `x-afb-ws-json1` is used as a subprotocol,
-* base.py provides AGLBaseService to be extended for each service
-* AGLBaseService has a `portfinder()` routine which will use `asyncssh` if used remotely,
-to figure out the port of the service's websocket that is listening on. When this was implemented services had a hardcoded listening port,
-and was often changed when a new service was introduced. If you specify port, pyagl will connect to it directly. If no port is specified and
-portfinder() cannot find the process or listening port should throw an exception and exit.
-* main() implementations in most PyAGL services' bindings are intended to be used as a convenient standalone utility to query verbs, although
-not necessarily available.
-* PyAGL bindings are organized in classes, method names and respective parameters mostly adhere to service verbs/apis described
-per service in https://git.automotivelinux.org/apps/agl-service-*/about
-For example, in https://git.automotivelinux.org/apps/agl-service-audiomixer/about/ the docs for the service describe 5 verbs -
-subscribe, unsubscribe, list_controls, volume, mute - and their respective methods in audiomixer.py.
-* as mentioned above `pytest` package is required for unit tests.
-* `pytest-async` is needed by pytest to cooperate with asyncio
-* `pytest-dependency` is used in cases where specific testing order is needed and used via decorators
-
-# 1. Using PyAGL
-Command line execution is intended for debugging and quick evaluation.
-There are few prerequisites to start using it. First, your AGL image **must** be bitbaked with **agl-devel** feature when sourcing __aglsetup.sh__;
-if not - the running AGL instance won't have websocket services exposed to listening TCP ports and PyAGL will fail to connect.
-
-```bash
-git clone "https://gerrit.automotivelinux.org/gerrit/src/pyagl"
-```
-Preferably create a virtualenv and install the packages in the env
-```bash
-user@debian:~$ python3 -mvenv ~/.virtualenvs/aglenv
-user@debian:~$ source ~/.virtualenvs/aglenv/bin/activate
-(aglenv) user@debian:~$ pip install -r requirements.txt
-```
-Hard requirements are asyncssh, websockets, pytest, pytest-dependency, pytest-async; the others in the file are dependencies of the mentioned packages.
-
-If you have installed PyAGL as python package or current working directory is in the project root:
-```
-(aglenv) user@debian:~/pyagl$ python3 -m pyagl.services.audiomixer 192.168.234.34 --list_controls
-```
-should produce the following or similar result depending on how many controls are exposed and which AGL version you are running:
-```
-matching services: ['afm-service-agl-service-audiomixer--0.1--main@1001.service']
-Requesting list_controls with id 359450446
-[RESPONSE][Status: success][359450446][Info: None][Data: [{'control': 'Master Playback', 'volume': 1.0, 'mute': 0},
-{'control': 'Playback: Speech-Low', 'volume': 1.0, 'mute': 0}, {'control': 'Playback: Emergency', 'volume': 1.0, 'mute': 0},
-{'control': 'Playback: Speech-High', 'volume': 1.0, 'mute': 0}, {'control': 'Playback: Navigation', 'volume': 1.0, 'mute': 0},
-{'control': 'Playback: Multimedia', 'volume': 1.0, 'mute': 0}, {'control': 'Playback: Custom-Low', 'volume': 1.0, 'mute': 0},
-{'control': 'Playback: Communication', 'volume': 1.0, 'mute': 0}, {'control': 'Playback: Custom-High', 'volume': 1.0, 'mute': 0}]]
-```
-
-# 2. Running the tests
-
-## Markers
-Before running the tests it must be noted that __Markers__ are metavariables applied to the tests which play important part
-in the behavior of pyagl and add great flexibility when deciding which tests to run.
-Each test suite usually have unambiguous marker and description in `pytest.ini` for the reason above.
-The default markers are applied in the list variable `pytestmark` in the beginning of each test file.
-Each test suite has at least 2 default markers.
-
-`pytest.mark.asyncio` is a special marker needed because we are running pytest in async mode,
-and the other marker is the name of the testsuite - for example `pytest.mark.geoclue` is for `geoclue` tests.
-
-`pytest.mark.dependency` is another special marker used by the pytest-dependency library helping for
-running tests in a particular order when a more complicated setup other than a fixture is needed for
-a test or the setup itself is a test or sequence of tests.
-
-`pytest.mark.hwrequired` is a marker signifying that additional hardware is required for tests to be successful - e.g. bluetooth phonebook tests need a phone with a pbap profile connected
-
-`pytest.mark.internet` is a marker for tests which require internet connection
-
-As mentioned above, behavior of pytest is altered by the markers because pytest does expression matching by marker and test names for which suite to be run.
-In the example below we select all internet requiring and subscription tests but skip those that require additional hardware.
-If we have a match with `internet or subscribe` the test will be selected, but if the test has `hwrequired` will be skipped, otherwise deselected overall.
-```

-## Locally - On the board itself
-There is the /usr/bin/pyagl convenience wrapper script which invokes pytest
-with the tests residing in `/usr/lib/python3.8/site-packages/pyagl/tests` which
-also will pass all commandline arguments down to pytest
-

-## Remotely
-You must export `AGL_TGT_IP` environment variable first, containing a string with a reachable IP address
-configured(either DHCP or static) on one of the interfeces on the AGL instance(board or vm) on your network.
-`AGL_TGT_PORT` is not required, however can be exported to skip over connecting to the board via ssh first
-in order to figure out the listening port of service.
-
-```console
-user@debian:~$ source ~/.virtualenvs/aglenv/bin/activate
-(pyagl) user@debian:~$ export AGL_TGT_IP=192.168.234.34
-(pyagl) user@debian:~$ cd pydev/pyagl/pyagl/tests

-# 3. Writing bindings and/or tests for new services
-This assumes you have already went through ["3. Developer Guides > Creating a new service"](../3_Developer_Guides/2_Creating_a_New_Service.md).
-
-Templates directory contains barebone _cookiecutter_ templates to create your project.
-If you do not intend to use cookiecutter, you need a simple service file in which you inherit AGLBaseService
-from base.py.
-You can take a look at pyagl/services/geoclue.py and pyagl/tests/test_geoclue.py which is probably the
-simplest binding in PyAGL for a reference and example. All basic methods like
-[send|receive|un/subscribe|portfinder] are implemented in the base class.
-You would need to do minimal work to create new service binding from scratch and by example of the geoclue service you need to do the following:
-
-* do the basic imports
-```python3
-from pyagl.services.base import AGLBaseService, AFBResponse
-import asyncio
-```
-
-* inherit AGLBaseService and type in the service class member the service name presuming you are following the AGL naming convention:
-(if your new service does not follow the convention, the portfider routine wont work and you'll have to specify service port manually)
-```python3
-class GeoClueService(AGLBaseService):
- service = 'agl-service-geoclue'
-```
-
-* if you intend to run the new service binding as a standalone utility, you might want to add your new options to the argparser
-```python3
- parser = AGLBaseService.getparser()
- parser.add_argument('--location', help='Get current location', action='store_true')
-```
-
-* override the __init__ method with the respective parameters as api(used in the binding) and systemd service slug
-```
- def __init__(self, ip, port=None, api='geoclue'):
- super().__init__(ip=ip, port=port, api=api, service='agl-service-geoclue')
-```
-
-* define your methods and send requests with .request() which prepares the data in a JSON format, request returns message id
-```
- async def location(self):
- return await self.request('location')
-```
-
-* get the raw response with data = await .response() or use .afbresponse() to get structured data
-
-PyAGL is written with asyncio so you'd need an event loop to get your code running.
-Most modules have standalone CLI functionality, which is done via ArgumentParser and each module that
-is CLI usable inherits static base parser and extends its arguments as shown in the example below:
-
-```python3
-async def main(loop):
- args = GeoClueService.parser.parse_args()
- gcs = await GeoClueService(args.ipaddr)
-
- if args.location:
- msgid = await gcs.location()
- print(f'Sent location request with messageid {msgid}')
- print(await gcs.afbresponse())
-
-if __name__ == '__main__':
- loop = asyncio.get_event_loop()
- loop.run_until_complete(main(loop))
-```
-`GeoClueService` will try to return an instance with connection to the service. It will throw an exception if it fails to do so.
-`AGLBaseService.afbresponse()` method is a wrapper on top of .response() which will prepare, validate and format data for a convenient usage intended for CLI usage.
-`AFBResponse.__str__` is also a convenience method to be able to print all relevant data in regarding state of the response.
-
-```console
-(aglenv) user@debian:~$ python3 -m pyagl.services.geoclue 192.168.234.251 --location
-matching services: ['afm-service-agl-service-geoclue--1.0--main.service']
-Sent location request with messageid 29188435
-[RESPONSE][Status: success][29188435][Info: GeoClue location data][Data: {'latitude': 42.6898421, 'longitude': 23.3099069, 'accuracy': 107.4702045}]
-```

-# 4. Environment variables
-The following environment variables are used in the PyAGL project:
-
-Variable | Description
---- | ---
-**AGL_TGT_IP** | **required**
-**AGL_TGT_PORT** | **optional**, when this is used portfinder() routine is skipped, attempts direct websocket connection to this port.
-**AGL_TEST_TIMEOUT** | **optional**, over-ride the default 5 second timeout value for binding responses. This is useful in many cases where a long-standing request has taken place - e.g. importing few thousand entries from a phonebook
-**AGL_AVAILABLE_INTERFACES** | **optional**, specify which of ethernet, wifi, and bluetooth interfaces are available. The value is a comma separated list, with a default value of "ethernet,wifi,bluetooth".
-**AGL_BTMAP_RECIPIENT** | **optional**, when running Bluetooth MAP tests, this would be used as phone number to write text messages to.
-**AGL_BTMAP_TEXT** | **optional**, when running Bluetooth MAP tests, messages will be composed with this text.
-**AGL_CAN_INTERFACE** | **optional**, specify the CAN interface to use for CAN testing, default value is "can0".
-**AGL_PBAP_PHONENUM** | **optional**, when running Bluetooth PBAP tests, this phone number will be used to .search().
-**AGL_PBAP_VCF** | **optional**, for the Bluetooh PBAP tests query a contact entry out of the phonebook.
-**AGL_BT_TEST_ADDR** | **optional**, for the Bluetooth tests pair/connect/disconnect with an actual Bluetooth device(phone)'s address . The address should have the DBus address style as "dev_00_01_02_03_04_05" instead of a regular colon-separated MAC address.
-
-# 5. Debugging
-PyAGL uses pythons logger library so you can rise the logging level and see the output from most of the modules,
-but was disabled by default because of the massive amount of output produced. When the default logger is enabled
-all other libraries will show their output with pyagl - e.g. websockets, asyncssh etc.
-
-README.md in the root directory of the project also contains useful information.
-
