PestPHP has a plugin that adds support for using Pest inside of PhpStorm (written by Oliver Nybroe). This plugin adds conveniences to working with Pest, such as running a Pest test from the PhpStorm UI (like PHPUnit) and supports auto-completion.
Having assertions available through auto-completion can help you see what assertions are available without leaving your code. You can also assign a value to a property before each test, and this plugin includes those properties as part of auto-completion.
In my opinion, one of the killer features in this plugin is seeing code coverage directly within the PhpStorm UI.

This plugin is available in the JetBrains marketplace: Pest – Plugins | JetBrains. You can also install Pest for PhpStorm in your editor by going to Preferences > Plugins > Marketplace and search for “Pest.”
