Compares tests execution times collected by jest-timing-reporter and produces a comment in the PR.

Sample

Usage

Install jest-timing-reporter in your project/repo.

Then add the following GitHub Action to your repository

name: jest-timing-action
# pull request on the master branch
on:
  pull_request:
    branches: [ master ]
jobs:
  pr_check:
    runs-on: ubuntu-latest
    name: Post Test Timing deltas on PR
    steps:
    - uses: actions/checkout@v2
    - name: PR Action
      uses: javierfernandes/jest-timing-action@master
      with:
        threshold: 25
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

And that's it. Now just make sure that you have your snapshots in the main branch. Create a PR that somehow impacts test execution times and create a PR, this action will post a comment with the times delta. On any further commit it will create a new updated comment.
