Installing/Upgrading

cdrouter is available on PyPI. To install the latest stable version from PyPI:

$ pip install -U cdrouter

cdrouter supports Python 3.5 or newer.

Publishing a New Release

To publish a new release of cdrouter.py, first ensure you have met the following prerequisites:

• You have Docker installed and running (https://docs.docker.com/engine/install/).

• You have SSH keys in ~/.ssh which allow you to push changes to this repository.

• You have your Git user.name and user.email config parameters set appropriately. If you have not already done so, set them by running:

  $ git config --global user.name "Your Name"
  $ git config --global user.email you@qacafe.com

• You have installed a PyPI (https://pypi.org/) token which gives you permission to upload packages for https://pypi.org/project/cdrouter/ in your ~/.pypirc. Your ~/.pypirc file should have the following [pypi] section (see https://packaging.python.org/en/latest/specifications/pypirc/#using-a-pypi-token):

  [pypi]
  username = __token__
  password = <insert-PyPI-token-here>
  

• You have the master branch checked out and are up to date with origin.

Once you have met the above prerequisites, from the root of this repository run ./docker.sh /bin/bash:

$ ./docker.sh /bin/bash

This will mount your local repository in an ephemeral Docker container, install cdrouter.py into the container and drop you into a /bin/bash shell. To publish a new release, run ./manage.sh publish from within the container:

$ ./manage.sh publish

You will be prompted for the version number <version> to use for the new release. Enter it without any leading v (for example, enter 1.2.3, not v1.2.3) and press <Enter>. After release has been built, you will be asked to confirm one last time. Press Ctrl+C to abort, otherwise press <Enter> to publish the release. Publishing the release will do the following:

• __version__ in cdrouter/__init__.py will be set to <version> and these changes will be pushed to origin/master.
• A new v<version> tag will be created (for example, if <version> is 1.2.3, a v1.2.3 tag will be created) and the new tag will be pushed to origin.
• A new <version> release of cdrouter (https://pypi.org/project/cdrouter) will be uploaded to PyPI.

Assuming there are no errors, congratulations! You have published a new release of cdrouter. Run exit or type Ctrl-D to exit out of the ephemeral Docker container and return to your normal prompt.

Unit Tests

Unit tests for cdrouter.py are written using pytest (https://docs.pytest.org) and run with tox (https://tox.wiki). Each test starts up an ephemeral CDRouter Docker container to test against. Tests are stored in the tests/ directory. The following tooling is required to run the unit tests:

• Docker must be installed and the docker command runnable by the current user. Follow the official install instructions (https://docs.docker.com/engine/install/) to ensure this is the case.

• Python 3.8 must be installed with a python3.8 binary available in your PATH.

• tox must be installed via pip3:

  $ pip3 install -U tox

  If you do not already have pip3 installed, follow the official install instructions (https://pip.pypa.io/en/stable/installation/) or use the get-pip.py script below to perform the installation automatically:

  $ curl -s https://bootstrap.pypa.io/pip/get-pip.py | python3

The unit tests are controlled by a number of a environment variables, some required while others are optional. Optional environment variables are listed further below. The required environment variables are:

• CDR_DOCKER_IMAGE: The CDRouter Docker image to use to test against. The unit tests automatically create and teardown Docker containers running this image during testing. Its value should be a Docker image name that can be passed directly to docker run. A good default is:

  CDR_DOCKER_IMAGE=registry.gitlab.com/qacafe/cdrouter/cdrouter/cdrouter:latest

  which should always be the latest CDRouter release.

• CDR_DOCKER_LICENSE: The base64-encoded contents of a CDRouter license file with all addons enabled to be used in the CDRouter Docker containers which are created during testing. If the CDRouter license file to be used exists at /path/to/cdrouter.lic, set this variable to:

  CDR_DOCKER_LICENSE=$(base64 -w0 /path/to/cdrouter.lic)

Finally, run the unit tests via:

$ CDR_DOCKER_IMAGE=registry.gitlab.com/qacafe/cdrouter/cdrouter/cdrouter:latest \
  CDR_DOCKER_LICENSE=$(base64 -w0 /path/to/cdrouter.lic) \
  tox -p

This will both lint the codebase using pylint and run all unit tests. You may sometimes want to run only a subset of tests. To run just the tests in tests/test_configs.py, run:

$ CDR_DOCKER_IMAGE=registry.gitlab.com/qacafe/cdrouter/cdrouter/cdrouter:latest \
  CDR_DOCKER_LICENSE=$(base64 -w0 /path/to/cdrouter.lic) \
  tox -e py38 -- tests/test_configs.py

To run just the test_list test in the TestConfigs class of tests/test_configs.py, run:

$ CDR_DOCKER_IMAGE=registry.gitlab.com/qacafe/cdrouter/cdrouter/cdrouter:latest \
  CDR_DOCKER_LICENSE=$(base64 -w0 /path/to/cdrouter.lic) \
  tox -e py38 -- tests/test_configs.py::TestConfigs::test_list

Below are the optional environment variables used by the unit tests:

• CDR_DOCKER_PULL: By default, the unit tests will ensure the Docker image specified by CDR_DOCKER_IMAGE is present and up to date via a call to docker pull. Sometimes this isn't necessary or desired, in which case setting CDR_DOCKER_PULL=0 will cause the unit tests to skip this step and assume the Docker image is already present and up to date. Setting CDR_DOCKER_PULL=0 is often necessary if CDR_DOCKER_IMAGE is set to a locally-built image rather than one pulled down from a Docker registry.
• CLOUDSHARK_URL & CLOUDSHARK_TOKEN: These variables specify the URL and valid API token of a CloudShark appliance. If these are not set, tests which require uploading capture files to a CloudShark appliance are skipped.
• RUN_LOUNGE_TESTS, LOUNGE_EMAIL, LOUNGE_URL & LOUNGE_INSECURE: By default, tests which require communicating with the QA Cafe Lounge are skipped. These tests can be run by setting RUN_LOUNGE_TESTS=1, in which case LOUNGE_EMAIL must be set to a valid email address for a contact in same Lounge account as the CDRouter license stored in CDR_DOCKER_LICENSE. Additionally, LOUNGE_URL and LOUNGE_INSECURE can be used to have the tests talk to a non-production Lounge.
