What this package does?

This package is used to validate the canonical data.

Starting a new project with template

• Add gtfs-canonical-validator package as dependency in your requirements.txt
• or pip install gtfs-canonical-validator
• Start using the packages in your code.

Initialize and Configuration

from gtfs_canonical_validator import CanonicalValidator

canonical_validator = CanonicalValidator(zip_file=<CANONICAL_ZIP_FILE_PATH>)
report = canonical_validator.validate()
print(report)

Testing

The project is configured with python to figure out the coverage of the unit tests. All the tests are in tests folder.

• To execute the tests, please follow the commands:

  pip install -r requirements.txt

  python -m unittest discover -v tests/unit_tests

• To execute the code coverage, please follow the commands:

  python -m coverage run --source=src/gtfs_canonical_validator -m unittest discover -s tests/unit_tests

  python -m unittest test_sample.MyTestCase.test_function - To run a single test case

  coverage html // Can be run after 1st command

  coverage report // Can be run after 1st command

• After the commands are run, you can check the coverage report in htmlcov/index.html. Open the file in any browser, and it shows complete coverage details

• The terminal will show the output of coverage like this

>  python -m unittest discover -v tests/unit_tests

Running validation on Local files

• Use the code in example.py to replace the dataset sources and run the code to get the validation report.
• An example report can be found at example-report.json
• The report explanation can be found here

Deployment:

• The library can be pushed to TestPy or PYPI

Deploy to TestPy

• On every push to dev branch, a workflow is triggered which publishes the updated version to TestPy

Deploy to PyPI

• This happens whenever a tag/release is created with *.*.* notation (eg. 0.0.8)
• To change the version, change the version at version.py
• To release a new version:
  • Go to Github link of this repository
  • Under releases, click on Draft a new release
  • Under choose a new tag, add a new tag v*.*.* , Generate Release notes
  • Choose main branch for release
  • Publish the release.
• This release triggers a workflow to generate the new version of the Package.
• The new package will be available at https://pypi.org/project/gtfs-canonical-validator/
