Continuous Integration

Various combinations of platforms and versions of Python are tested via:

Testing

Tests are written using unittest and require no third-party packages.

Depending on what type of source is available for the package, the following commands can be used to run the test suite.

Git Repository

When working within a Git working copy, or an archive of the Git repository, the full test suite is run via:

python run.py tests

To run only some tests, pass a regular expression as a parameter to tests.

python run.py tests path

PyPi Source Distribution

When working within an extracted source distribution (aka .tar.gz) from PyPi, the full test suite is run via:

python setup.py test

Test Cases

The test cases for the library are comprised of:

Development

To install the package used for linting, execute:

pip install --user -r requires/lint

The following command will run the linter:

python run.py lint

Support for code coverage can be installed via:

pip install --user -r requires/coverage

Coverage is measured by running:

python run.py coverage

To install the packages requires to generate the API documentation, run:

pip install --user -r requires/api_docs

The documentation can then be generated by running:

python run.py api_docs

The following will run a test that connects to all (non-adult) sites in the Alexa top 1000 that respond on port 443:

python run.py stress_test

Once the script is complete, results that differ between the OS validation and the certvalidator validation will be listed for further debugging.

To change the version number of the package, run:

python run.py version {pep440_version}

To install the necessary packages for releasing a new version on PyPI, run:

pip install --user -r requires/release

Releases are created by:

CI Tasks

A task named deps exists to ensure a modern version of pip is installed, along with all necessary testing dependencies.

The ci task runs lint (if flake8 is avaiable for the version of Python) and coverage (or tests if coverage is not available for the version of Python). If the current directory is a clean git working copy, the coverage data is submitted to codecov.io.

python run.py deps
