Cypress

Why Cypress?

  • Free and open source

  • Test modern apps directly in the browser

  • Write your first passing test in minutes

    • npm install --save-dev cypress
    • npx cypress open # generates cypress project

  • Debug failures directly in the browser:

    • Time Travel

    • Screenshots and Videos

    • Live Reload

How to keep project healthy

Leveraging Regular Cypress E2E Test Execution with GitHub

Test execution

For every commit on:

  • prod/main/dev branches

  • Pull Request

 - ?

Locally:

  • pre-commit - probably not

  • pre-push - well... probably nothing more than smoke tests

Cypress & Github configuration

Leveraging Regular Cypress E2E Test Execution with GitHub

GOAL: Cypress checks

Simple github Action

name: End-to-end tests
on: push
jobs:
  cypress-run:
    runs-on: ubuntu-22.04
    steps:
      - name: Checkout
        uses: actions/checkout@v3

      # build your dedicated instance here

      - name: Cypress run
        uses: cypress-io/github-action@v5

goal: videos & screenshots

Storing Artifacts

name: Artifacts
on: push
jobs:
  cypress-run:
    runs-on: ubuntu-22.04
    name: Artifacts
    steps:
      - uses: actions/checkout@v3
      - uses: cypress-io/github-action@v5
      - uses: actions/upload-artifact@v3
        if: failure()
        with:
          name: cypress-screenshots
          path: cypress/screenshots
      - uses: actions/upload-artifact@v3
        if: always()
        with:
          name: cypress-videos
          path: cypress/videos

GOAL: Inline comments
