Testing of source and binary distributions relies too much on manual testing by people.

We propose to set up Dockerfiles and CI scripts that document and test the expected capabilities of source and binary Sage distributions; and of downstream distribution packaging.

Testing of source trees and source distributions: (in progress)

With the important changes brought by #27330 (Meta-ticket: spkg-configure: Try to use as many system packages as possible), sage-the-distribution has become less monolithic; it now interacts in a more complex way with distribution packaging. We propose to add infrastructure for testing correct installation of sage source distributions on a variety of platforms.

1. We collect information about distribution packages systematically and store it in on a per-SPKG basis in build/pkgs/SPKG/distros/. (Right now this information is scattered - in downstream sage distribution packagers' build scripts, trac tickets, replies to bug reports in google groups, the sage installation manual, personal knowledge...) This is part of Add debian/fedora/arch/conda package information to build/pkgs, generate Dockerfiles and installation help; add tox.ini #29053, for debian/fedora/arch/conda (with follow-up tickets tox.ini, build/bin/write-dockerfile.sh: Add gentoo linux, add more gentoo packages #29105, Add cygwin package information #29106 for other platforms).

2. We generate well-defined test environments in the form of Dockerfiles. This makes it possible to test, on one's development computer, the correct installation of sage-the-distribution on a variety of platforms and configurations. Add debian/fedora/arch/conda package information to build/pkgs, generate Dockerfiles and installation help; add tox.ini #29053 provides build/bin/write-dockerfile.sh that generates the Dockerfile using the information in 1. The minimal configuration has just the packages that are needed for a build to succeed. The standard configuration installs all distribution packages that sage knows how to use.

3. Running tests on many test environments is automated using tox in Add debian/fedora/arch/conda package information to build/pkgs, generate Dockerfiles and installation help; add tox.ini #29053. The top-level tox.ini file defines the test environments. Using tox's factor conditions (https://tox.readthedocs.io/en/latest/config.html#complex-factor-conditions), there is a succinct description of many test environments. For example, we can run tox -e docker-debian-stretch-minimal,docker-arch-latest-standard.

4. Add GitHub Actions workflow for testing the build on various Linux distributions via docker; macOS with homebrew; and Windows (cygwin) #29087 automates running the tox tests for a selection of 34 platforms/configurations using a GitHub Actions workflow on every git push to a GitHub repository. An example run: https://github.com/mkoeppe/sage/actions/runs/32812271
