QuantumKitHubActions

Shared workflows for the QuantumKitHub Julia packages

Test Groups

The TestGroups workflow auto-discovers test groups from subdirectories of test/ and runs them in parallel across a matrix of Julia versions and operating systems. Each subdirectory becomes a separate parallel job; groups are passed to the test suite via test_args and dispatched by ParallelTestRunner.jl.

Test directory structure

Organize your test/ directory with one subfolder per test group. Place shared setup code in a test/setup/ directory (excluded by default):

test/
├── setup/          # shared utilities, excluded from test groups
├── core/
│   └── runtests.jl
├── extensions/
│   └── runtests.jl
└── runtests.jl     # ParallelTestRunner.jl entry point

A minimal test/runtests.jl using ParallelTestRunner.jl:

using ParallelTestRunner
ParallelTestRunner.runtests()

Example workflow

name: "Tests"

on:
  push:
    branches:
      - main
    tags: '*'
  pull_request:
  workflow_dispatch:

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: ${{ startsWith(github.ref, 'refs/pull/') }}

jobs:
  tests:
    uses: "QuantumKitHub/QuantumKitHubActions/.github/workflows/TestGroups.yml@main"
    with:
      fast: ${{ github.event.pull_request.draft == true }}
    secrets:
      CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }}

Branch protection

Add ci-success as a required status check in your repository's branch protection rules. This single stable check name reflects the combined result of all parallel test jobs regardless of how many groups exist.

Inputs

Input	Type	Default	Description
exclude	string	'["setup", "gpu"]'	JSON array of test/ subdirectory names to exclude from discovery
julia-version	string	'["min", "1"]'	JSON array of Julia versions to test
os	string	'["ubuntu-latest", "macos-latest", "windows-latest"]'	JSON array of runner OSes
fast	boolean	false	Collapse matrix to ubuntu-latest + julia 1, append --fast to test args
nthreads	number	2	Julia thread count per job
timeout-minutes	number	60	Per-job timeout
localregistry	string	""	Newline-separated local registry URLs
cache	boolean	true	Enable julia-actions/cache
buildpkg	boolean	true	Enable julia-actions/julia-buildpkg
coverage	boolean	true	Collect and upload coverage (only on ubuntu-latest + julia 1)
coverage-directories	string	"src,ext"	Directories for julia-processcoverage

Secrets: CODECOV_TOKEN (optional, only needed when coverage: true)

Fast path

When fast: true, the matrix collapses to a single OS and Julia version and --fast is appended to each group's test args. Wire it to draft PR detection for quick feedback during development:

with:
  fast: ${{ github.event.pull_request.draft == true }}

ParallelTestRunner.jl passes --fast through to individual test files, which can use it to skip slow or expensive tests.

Excluding folders

Override exclude to control which subdirectories are skipped:

with:
  exclude: '["setup", "gpu", "cuda"]'

Tests

The Tests workflow is designed to run the tests suite for Julia packages. The workflow works best with a runtests.jl script that looks like this:

using Test

# check if user supplied args
pat = r"(?:--group=)(\w+)"
arg_id = findfirst(contains(pat), ARGS)
const GROUP = if isnothing(arg_id)
    uppercase(get(ENV, "GROUP", "ALL"))
else
    uppercase(only(match(pat, ARGS[arg_id]).captures))
end

@time begin
    if GROUP == "ALL" || GROUP == "CORE"
        @time include("test_core1.jl")
        @time include("test_core2.jl")
        # ...
    end
    if GROUP == "ALL" || GROUP == "OPTIONAL"
        @time include("test_optional1.jl")
        @time include("test_optional2.jl")
        # ...
    end
    # ...
end

An example workflow that uses this script is:

name: Tests
on:
  push:
    branches:
      - 'master'
      - 'main'
      - 'release-'
    tags: '*'
    paths-ignore:
      - 'docs/**'
  pull_request:
  workflow_dispatch:

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  # Cancel intermediate builds: only if it is a pull request build.
  cancel-in-progress: ${{ startsWith(github.ref, 'refs/pull/') }}

jobs:
  tests:
    name: "Tests"
    strategy:
      fail-fast: false
      matrix:
        version:
          - 'lts' # minimal supported version
          - '1' # latest released Julia version
        # optionally, you can specify the group of tests to run
        # this uses multiple jobs to run the tests in parallel
        # if not specified, all tests will be run
        group:
          - 'core'
          - 'optional'
        os:
          - ubuntu-latest
          - macOS-latest
          - windows-latest
    uses: "ITensor/ITensorActions/workflows/Tests.yml@main"
    with:
      group: "${{ matrix.group }}"
      julia-version: "${{ matrix.version }}"
      os: "${{ matrix.os }}"
    secrets:
      CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }}

Documentation

The documentation workflow is designed to build and deploy the documentation for Julia packages. The workflow works best with a docs/make.jl script that looks like this:

using MyPackage
using Documenter

makedocs(; kwargs...)
deploydocs(; kwargs...)

An example workflow that uses this script is:

name: "Documentation"

on:
  push:
    branches:
      - main
    tags: '*'
  pull_request:
  schedule:
    - cron: '1 4 * * 4'

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: ${{ github.ref_name != github.event.repository.default_branch || github.ref != 'refs/tags/v*' }}

jobs:
  build-and-deploy-docs:
    name: "Documentation"
    uses: "ITensor/ITensorActions/workflows/Documentation.yml@main"
    secrets: "inherit"

Formatting

The formatting workflow is designed to run Runic on Julia packages and verify the formatting.

name: "Format Check"

on:
  push:
    branches:
      - 'main'
    tags: '*'
  pull_request:

jobs:
  format-check:
    name: "Format Check"
    uses: "QuantumKitHub/QuantumKitHubActions/.github/workflows/FormatCheck.yml@main"

LiterateCheck

The LiterateCheck workflow is designed to keep the README of Julia packages up to date. The workflow would look like:

name: "Literate Check"

on:
  push:
    branches:
      - 'main'
    tags: '*'
  pull_request:

jobs:
  format-check:
    name: "Literate Check"
    uses: "ITensor/ITensorActions/workflows/LiterateCheck.yml@main"
