+You can check coverage simply in the terminal with the
+[pytest-cov](https://pypi.org/project/pytest-cov/) plugin. However you might
+consider a third-party code coverage analytics and reporting service. There are
+two that we've used and they're both rather similar. They render the code with
+highlighting to show which lines are not executed but the tests, and can track
+test coverage over time.

+| [Codecov](https://docs.codecov.com/docs) | Hosted service to report code coverage metrics. Occasionally slow to update after a report is updated, can be configured to add extra CI checks. This service is probably more widely used and is [free for both open-source and private projects](https://about.codecov.io/pricing/). | 🟢  |
+| [Coveralls](https://docs.coveralls.io/)  | Hosted service to report code coverage metrics. Very similar to codecov and we don't strongly recommend one over the other. This service is only [free for open-source projects](https://coveralls.io/pricing).                                                                        | 🟢  |
