Setting up development environment¶
Before you start, ensure you have Python installation in version 3.7 or higher. Please see the official Python documentation in case you have to upgrade or install certain Python version.
Clone the project. Inside the project folder create a new virtual environment and activate it:
$ python -m venv env $ source env/bin/activate
On Windows, activate by executing the following:
When your virtual environment is ready, install required dependencies:
$ pip install -r requirements.txt
To use library functions directly from the source code, execute the following to point to the source folder in PYTHONPATH variable and run the interpreter:
$ PYTHONPATH=$PYTHONPATH:src/ python
Verify that packages are accessible:
>>> import onapsdk
You can then start working with library functions as needed.
New ONAP component package¶
When you create a new ONAP component package and wants to use Jinja templates you need to create templates directory to store them in a newly created package. Furthermore you need to add a PackageLoader in utils.jinja module.
$ pip install tox
To run all unit test, lint and docstyle checks, inside the project folder simply execute tox:
Please note that the above runs unit tests on all major versions of Python available on your OS (3.7, 3.8, 3.9). To limit execution to only specific version of Python Interpreter, use the following example:
$ tox -e py37
It is possible to run integration tests using mock-servers project.
Make sure Docker Compose is available on your system. Install required dependencies:
$ pip install pytest mock
Go to integration_tests/ directory and execute:
$ docker-compose up
Please note that docker-compose attempts to create subnet 172.20.0.0/24, so it can not be run if the scope is already allocated. Also, containers are not reachable by their IP addresses on Windows host since Docker for Windows does not support bridged network interface for Linux containers. For reference, please see Docker docs.
Once containers are running, execute the following in the project’s directory:
$ PYTHONPATH=$PYTHONPATH:integration_tests/:src/ ONAP_PYTHON_SDK_SETTINGS="local_urls" pytest -c /dev/null --verbose --junitxml=pytest-integration.xml integration_tests
Please make sure all the test are passing before creating merge request.
