edx-repo-health

edx-repo-health is a set of checks of the health of repositories. They are written similar to pytest tests, and run in pytest using a customized pytest plugin (pytest-repo-health).

• Each check gathers information about a given repository.
• Each check is meant to be minimal and only check for simple specific things. This is to make it easier to debug changes.
• Unlike test functions, checks should not use asserts.
• Each check writes its result to a dictionary.
• The completed dictionary is written as a YAML file when all the checks have been run.

Installation

1. git clone this repository:

   $ git clone git@github.com:edx/edx-repo-health.git
   

2. run make requirements to install reqs for this repo

3. run pip install -e . to install this project

Usage

• Follow Installation steps above

• cd into the directory you wish to run checks on

• Set credentials:

  • Export GITHUB_TOKEN into environment, containing GitHub personal API token with read access to edx org.
  • Export READTHEDOCS_API_KEY into the environment, with a Read The Docs API token.
  • Note: a ~/.netrc file will override these settings and may interfere. You can use NETRC=/dev/null to hide the file if needed.

• Run the run_checks command

  run_checks is a CLI wrapper around pytest and pytest-repo-health. Running run_checks will run all checks located in edx-repo-health repo on the directory you are currently cd'd into. The results will be written into a repo_health.yaml file.

  If you would like to add further flags to the pytest call, you can add the flags after run_checks command and they will be passed on the pytest automatically. Find out about additional options at pytest-repo-health or run pytest --help command.

Design

edx-repo-health is part of a set of tools that together collect results of checks against multiple repositories. Then, taking the individual results as input, it can output the data in different formats including aggregated views of the data.

The following describes the repo health pipeline that currently uses edx-repo-health (some of the following is private to edx.org and is mentioned because we think it is useful information to have):

• edx-repo-health contains all the repo health checks that run on edX repositories
  • repo_health_dashboard script aggregates data generated on each repository by org-repo-health-report jenkins job into a CSV report
    • this script would also allow you to create other custom dashboards
• pytest-repo-health repository contains the pytest plugin that allows us to run these checks on a repository
• org-repo-health-report jenkins job runs all the checks defined in this repo on repositories in edX github organization (private to edx.org).
  • org-repo-health-report job definition (private to edx.org)
• repo-health-data repository contains all the data generated by repo health pipeline (private to edx.org).
  • On every merge to master, a GitHub action updates info in Repo Health Dashboard spreadsheet
• Repo Health Dashboard is the end result of this pipeline google spreadsheet (private to edx.org).

Adding Checks

For details on adding new checks, please See how_tos.

Future improvements

• Documenting standard reqs/checks in each check better.
• Create tests for the checks and make sure they behave correctly for different dir/file structure.
