Skip some tests on nightly in CI

General Usage
1

I am using Github Actions for CI on a package. I want to skip some tests on nightly, but it is a moving target and I don’t want to keep updating the code after every release.

I am wondering what the best way to do this is, I thought of

if isempty(VERSION.prerelease)
  # do my tests
end

One way would be by setting an environment variable in the CI job:

name: CI

on:
  push:
    branches:
      - main
  pull_request:
  workflow_dispatch:

jobs:
  test:
    runs-on: ${{ matrix.os }}
    timeout-minutes: 45
    strategy:
      fail-fast: false
      matrix:
        version:
          - "1"
          - "nightly"
        os:
          - ubuntu-latest

    steps:
      - uses: actions/checkout@v2
        with:
          persist-credentials: false

      - uses: julia-actions/setup-julia@v1
        with:
          version: ${{ matrix.version }}

      - run: julia -e '@show get(ENV, "CI_MATRIX_VERSION", "nothing") == "nightly"'
        env:
            CI_MATRIX_VERSION: ${{ matrix.version }}

which prints

get(ENV, "CI_MATRIX_VERSION", "nothing") == "nightly" = false

on matrix version “1” and prints

get(ENV, "CI_MATRIX_VERSION", "nothing") == "nightly" = true

on matrix version “nightly”.

Thanks, that’s a very elegant solution.
