Create a test that actually tests the network #3
Description
There is currently only one 'test' in this project, which runs all the tests and notebooks of the other ScopeSim projects, and then creates a pull request for any new files that are fetched by those tests. Normally, there should be no such new files; there should only be new files when there are new tests, e.g. using a new filter or something like that.
This means that under normal circumstances, there is no test that checks whether the servers that e.g. skycalc_ipy tries to reach actually work. It would be useful to know whether those services are still up, so we should create some tests that run without caching data. However, maybe that should be done in the projects themselves?
