Long topic line summarizes everything but here are details.

To make a long story short, I need a way to test SeisIO.jl that supports encrypted test files. Travis-CI does this, but also started charging $70/month in June. SeisIO supports several data formats with redistribution restrictions, so I need some data to be accessible only during testing. Travis-CI simply used an encrypted tarball. That worked.

Are there any reliable CI services that are free, support testing in Linux environments, and have well-documented ways to handle such private data? Is there a different preferred method for testing Julia packages in a clean environment? I’m not even sure where to find information on what everyone is using for their package tests these days – it’s been 2 years since I had to make such fundamental changes to how I test, so I’m a bit behind, as you can imagine.

Thanks in advance.

Most packages have moved to GitHub Actions, which offers free cross-platform testing. The easiest way to set it up may be creating a mock package for SeisIO using PkgTemplates.jl with the [`GitHubActions`](https://invenia.github.io/PkgTemplates.jl/dev/user/#PkgTemplates.GitHubActions) CI settings, then copying CI.yml from the mock directory into your package directory. You should be able to add your encryption key as an [encrypted secret](https://docs.github.com/en/actions/reference/encrypted-secrets) that can be accessed as an environment variable within the CI job.
