pysdccc

This python packages provides a convenient way to execute the SDCcc test suite.

This wrapper is only compatible with SDCcc versions later than internal-baseline-001.

Installation

Download from pypi using pip install pysdccc. There is also an option to use this via the command line by installing pysdccc[cli].

Usage

Quick start

import pysdccc


async def main():
    if not await pysdccc.is_downloaded('my-specific-version'):
        await pysdccc.download('https://url/to/sdccc.zip')

    runner = pysdccc.SdcccRunner('/path/to/sdccc/result/directory')

    # https://github.com/Draegerwerk/SDCcc/?tab=readme-ov-file#exit-codes
    return_code, direct_result, invariant_result = await runner.run(
        config='/path/to/configuration/file.toml',
        requirements='/path/to/requirements/file.toml',
    )
    if direct_result is None or invariant_result is None:
        print('No result file available')
        return

    for test_case in direct_result + invariant_result:
        print(f'{test_case.test_identifier}: {test_case.is_passed}')

If you look for a synchronous version. Please note this is deprecated. The async methods are the preferred way.

import pysdccc


def main():
    if not pysdccc.is_downloaded_sync('my-specific-version').result():
        pysdccc.download_sync('https://url/to/sdccc.zip').result()

    runner = pysdccc.SdcccRunnerSync('/path/to/sdccc/result/directory')

    # https://github.com/Draegerwerk/SDCcc/?tab=readme-ov-file#exit-codes
    return_code, direct_result, invariant_result = runner.run(
        config='/path/to/configuration/file.toml',
        requirements='/path/to/requirements/file.toml',
    ).result(timeout=60)  # use .result(timeout=...) to wait for the result in a synchronous way

    # checkout example from above ...

Create configuration file

Configure the test consumer. Check the test consumer configuration for more information.

import anyio
import toml  # has to be installed by the user

import pysdccc


async def main():
    config = {
        'SDCcc': {
            ...  # add all relevant config parameter
        }
    }
    config_path = anyio.Path('/path/to/configuration/file.toml')
    await config_path.write_text(toml.dumps(config))

    runner = pysdccc.SdcccRunner('/path/to/sdccc/result/directory')

    await runner.run(config=config_path, requirements='/path/to/requirements/file.toml')

    # or if you have already downloaded SDCcc
    config = await runner.get_config()  # load default configuration
    config['SDCcc']['Consumer']['DeviceEpr'] = 'urn:uuid:12345678-1234-1234-1234-123456789012'  # e.g. change device epr
    # save and run as above

Create requirements file

Enable or disable specific requirements. Check the test requirements for more information.

import anyio
import toml  # has to be installed by the user

import pysdccc


async def main():
    requirements = {
        # the standard name is the key, the requirement from the standard is the value
        'BICEPS': {
            ...  # add all requirements to be tested
        }
    }
    requirements_path = anyio.Path('/path/to/requirement/file.toml')
    await requirements_path.write_text(toml.dumps(requirements))

    runner = pysdccc.SdcccRunner('/path/to/sdccc/result/directory')

    # optionally, check whether you did not add a requirement that is not available
    await runner.check_requirements(requirements_path)
    await runner.run('/path/to/configuration/file.toml', requirements=requirements_path)

    # or, if you have already downloaded SDCcc
    requirements = await runner.get_requirements()  # load default configuration
    requirements['BICEPS']['R0033'] = False  # e.g. disable biceps R0033
    # save and run as above

Create test parameter configuration

Some tests require individual parameters. Check the test parameter configuration for more information.

import anyio
import toml  # has to be installed by the user

import pysdccc


async def main():
    testparameter_config = {'TestParameter': {...}}
    testparameter_config_path = anyio.Path('/path/to/test_parameter/file.toml')
    await testparameter_config_path.write_text(toml.dumps(testparameter_config))

    runner = pysdccc.SdcccRunner('/path/to/sdccc/result/directory')
    await runner.run(
        config='/path/to/configuration/file.toml',
        requirements='/path/to/requirements/file.toml',
        testparam=testparameter_config_path,
    )

    # or, if you have already downloaded SDCcc
    testparameter_config = await runner.get_test_parameter()  # load default configuration
    testparameter_config['TestParameter']['Biceps547TimeInterval'] = 10
    # save and run as above

Logging

The SDCcc runner provides a logger called pysdccc.run that can be used to log messages during the execution of the tests. Stdout is mapped to logging level info and stderr to error. Be aware that no further processing of the SDCcc process output is done. Depending on the format you use you may get duplicated timestamps, etc. Also, it might happen that a java error can stretch over multiple lines, which may result in multiple log messages in python for the same java error.

Execute SDCcc from command-line interface (cli)

There exists a cli wrapper for the SDCcc executable. If pysdccc[cli] is installed, sdccc can be used to execute arbitrary SDCcc commands, e.g. sdccc --version. More information can be found here.

Also, you can manually install and uninstall sdccc versions using the cli, e.g. uv run pysdccc install https://url/to/sdccc.zip or from a local path uv run pysdccc install path/to/sdccc.zip.
