Testing julia.withPackages

This folder contains a test suite for ensuring that the top N most popular Julia packages (as measured by download count) work properly. The key parts are

  • top-julia-packages.nix: an impure derivation for fetching Julia download data and processing it into a file called top-julia-packages.yaml. This YAML file contains an array of objects with fields "name", "uuid", and "count", and is sorted in decreasing order of count.
  • julia-top-n: a small Haskell program which reads top-julia-packages.yaml and builds a julia.withPackages environment for each package, with a nice interactive display and configurable parallelism. It also tests whether evaluating using <package-name> works in the resulting environment.

Warning: These tests should only be run on maintainer machines, not Hydra! julia.withPackages uses IFD, which is not allowed in Hydra.

Quick start

# Test the top 100 Julia packages
./run_tests.sh -n 100

Options

You can run ./run_tests.sh --help to see additional options for the test harness. The main ones are

  • -n/--top-n: how many of the top packages to build (default: 100).
  • -p/--parallelism: how many builds to run at once (default: 10).
  • -c/--count-file: path to top-julia-packages.yaml.
