Jest - GitHub Actions
Running Jest in Parallel on GitHub Actions using Matrix Workflow
Currents uses the native Jest sharding (Jest v28+) to split the tests between multiple containers.
Here's an example workflow configuration file:
name: Run Jest
on:
push:
branches:
- main
pull_request:
branches:
- main
jobs:
test:
runs-on: ubuntu-latest
strategy:
matrix:
shard: [1, 2]
steps:
- name: Checkout code
uses: actions/checkout@v4
- name: Set up Node.js
uses: actions/setup-node@v4
with:
node-version: "20"
- name: Install dependencies
run: npm install
- name: Run tests in shard ${{ matrix.shard }}
run: |
npx jest --shard=${{ matrix.shard }}/2
- name: Upload test results to Currents.dev
# CURRENTS_RECORD_KEY is a secret stored in the repository settings
env:
CURRENTS_RECORD_KEY: ${{ secrets.CURRENTS_RECORD_KEY }}
run: |
npx currents upload --project-id mdXsz8 --ci-build-id ${{ github.repository }}-${{ github.run_id }}-${{ github.run_attempt }}
