Parallel Testing

note

Parallel unit testing is currently in beta testing. Please let us know any issues you may come across. It is generally a drop-in replacement for PHPUnit but does play better with PHPUnit 10+.

By default, PHPUnit runs tests sequentially. This can be slow, especially if you have a lot of tests. To speed up your test suite, you can run tests in parallel. To get started, you'll need to install the paratest package:

composer require --dev brianium/paratest

You can then call the vendor/bin/paratest binary to run your tests in parallel:

vendor/bin/paratest

You should also update your composer.json file to include a script to run your tests in parallel:

{
  "scripts": {
    "test": "vendor/bin/paratest"
  }
}
