Test cases based on Orekit

See original GitHub issue

From https://github.com/poliastro/poliastro/wiki/Validation : Orekit is an open-source space dynamics library written in Java. A Python wrapper is maintained by @petrushy (https://gitlab.orekit.org/orekit-labs/python-wrapper), which allows to include Orekit in the test cases.

🎯 Goal

Validate poliastro against Orekit

📋 Steps

Include Orekit as a dependency in [options.extras_require] in setup.cfg. Orekit is distributed only via conda, how can we proceed?
Import Orekit data files, which contain Earth Orientation Parameters, leap seconds history, etc. It is maintained in https://gitlab.orekit.org/orekit/orekit-data. There are several possibilities:
1. Download it as a zip somewhere in the repo and let this method do the job: https://gitlab.orekit.org/orekit-labs/python-wrapper/blob/master/python_files/pyhelpers.py#L37
2. Unzip the current version in a folder somewhere in the repo
3. Have the Git repository synchronized as a submodule. Probably too much effort for the moment
4. Do not store the data in the repo, download it when installing poliastro (dev), by including it in setup.cfg
- Common for all four possibilities: where is it best to store the data? In a folder named data in the root folder? Or is it poliastro’s philosophy not to store any data in the repo? I did not see any SPICE kernel or anything in the repo, just code.
Write test cases 😃 Given that Orekit requires to start a JVM, I would rather write the test cases in separate files, what do you think?

In case anyone tries to run the Orekit test cases (still in a private branch), beware that the Python wrapper does not work with doctest at the moment, the test cases will return errors&warnings. This is probably due to JCC, the issue is being investigated by the kind Petrus: https://issues.apache.org/jira/browse/PYLUCENE-51
