Testing

Ghostwire’s own test suite (Vitest for the JS core, Pest 4 + Orchestra Testbench for PHP, Pest 4 + Playwright for real-browser geometry/accessibility) is the reference for testing apps that use it.

Testing a component that uses wire:ghost

Livewire’s own Livewire::test() helper works unchanged — Ghostwire’s behavior is entirely client-side JS, so PHP-level component tests don’t need to know it exists.

Browser-testing skeleton behavior

Use Pest 4’s browser plugin (pestphp/pest-plugin-browser) directly against your app:

it('shows a skeleton while the table refreshes', function () {
    $page = visit('/products');
    $page->click('#refresh-btn');
    $page->assertVisible('.gw-bone');
});

Accessibility

assertNoAccessibilityIssues() (axe-core, via the same Pest browser plugin) is how Ghostwire’s own CI verifies zero accessibility findings — recommended at the strictest level (assertNoAccessibilityIssues(3)), not the method’s own default of 1.

CI gotcha, if you use pest-plugin-browser yourself

Never pipe vendor/bin/pest through a background | tail — the plugin’s spawned playwright run-server processes inherit the pipe’s file descriptor and never close it, hanging indefinitely regardless of actual test speed. Call vendor/bin/pest directly.
