Lightspeed

Installation

Install with composer:

composer require --dev lightspeedphp/lightspeed

Usage

Once installed, you can immediately run php vendor/bin/lightspeed to execute your tests. It will proxy to PHPUnit or to Pest if you have it installed.

Lightspeed is best used within CI where it can run on multiple machines at once to parallelise the execution of your tests. It currently supports GitHub Actions and Buildkite.

GitHub Actions

Here is an example workflow file to execute your tests in parallel. Note you must set the env vars manually for tests to be correctly split between jobs.

name: Demo

on: ['push']

jobs:
  ci:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node_count: [3]
        node_index: [0, 1, 2]

    name: Demo

    steps:
    - name: Checkout
      uses: actions/checkout@v3

    - name: Setup PHP
      uses: shivammathur/setup-php@v2
      with:
        php-version: 8.0
        tools: composer:v2
        coverage: none

    - name: Install PHP dependencies
      run: composer update --no-interaction --no-progress

    - name: Tests (${{ matrix.node_index}})
      env:
        LIGHTSPEED_NODE_COUNT: ${{ matrix.node_count }}
        LIGHTSPEED_NODE_INDEX: ${{ matrix.node_index }}
      run: php vendor/bin/lightspeed --colors=always

Buildkite

Buildkite is supported out of the box by setting the parallelism command step attribute. You can parallelise your test steps with as much agents as you can to minimise test time.

steps:
  - label: ':php: Run tests'
    commands:
      - composer update --no-interaction --no-progress
      - php vendor/bin/lightspeed
    parallelism: 3
    plugins:
      - docker#v4.14.0:
          image: composer:2
          propagate-environment: true
