Testing

You are currently viewing the documentation for Filament 2.x, which is a previous version of Filament.Looking for the current stable version? Visit the 5.x documentation.

All examples in this guide will be written using Pest. However, you can easily adapt this to PHPUnit. Since the form builder works on Livewire components, you can use the Livewire testing helpers. However, we have custom testing helpers that you can use with forms:

Filling a form

To fill a form with data, pass the data to fillform():

use function Pest\Livewire\livewire;

livewire(CreatePost::class)
    ->fillForm([
        'title' => fake()->sentence(),
        // ...
    ]);

Note that if you have multiple forms on a Livewire component, you can specify which form you want to fill using fillForm([...], 'createPostForm').

To check that a form has data, use assertFormSet():

use Illuminate\Support\Str;
use function Pest\Livewire\livewire;

it('can automatically generate a slug from the title', function () {
    $title = fake()->sentence();

    livewire(CreatePost::class)
        ->fillForm([
            'title' => $title,
        ])
        ->assertFormSet([
            'slug' => Str::slug($title),
        ]);
});

Note that if you have multiple forms on a Livewire component, you can specify which form you want to check using assertFormSet([...], 'createPostForm').

Validation

Use assertHasFormErrors() to ensure that data is properly validated in a form:

use function Pest\Livewire\livewire;

it('can validate input', function () {
    livewire(CreatePost::class)
        ->fillForm([
            'title' => null,
        ])
        ->assertHasFormErrors(['title' => 'required']);
});

And assertHasNoFormErrors() to ensure there are no validation errors:

use function Pest\Livewire\livewire;

livewire(CreatePost::class)
    ->fillForm([
        'title' => fake()->sentence(),
        // ...
    ])
    ->call('save')
    ->assertHasNoFormErrors();

Note that if you have multiple forms on a Livewire component, you can pass the name of a specific form as the second parameter like assertHasFormErrors(['title' => 'required'], 'createPostForm') or assertHasNoFormErrors([], 'createPostForm').

Form existence

To check that a Livewire component has a form, use assertFormExists():

use function Pest\Livewire\livewire;

it('has a form', function () {
    livewire(CreatePost::class)
        ->assertFormExists();
});

Note that if you have multiple forms on a Livewire component, you can pass the name of a specific form like assertFormExists('createPostForm').

Fields

To ensure that a form has a given field pass the field name to assertFormFieldExists():

use function Pest\Livewire\livewire;

it('has a title field', function () {
    livewire(CreatePost::class)
        ->assertFormFieldExists('title');
});

You may pass a function as an additional argument in order to assert that a field passes a given “truth test”. This is useful for asserting that a field has a specific configuration:

use function Pest\Livewire\livewire;

it('has a title field', function () {
    livewire(CreatePost::class)
        ->assertFormFieldExists('title', function (TextInput $field): bool {
            return $input->isDisabled();
        });
});

Note that if you have multiple forms on a Livewire component, you can specify which form you want to check for the existence of the field like assertFormFieldExists('title', 'createPostForm').

Hidden fields

To ensure that a field is visible pass the name to assertFormFieldIsVisible():

use function Pest\Livewire\livewire;

test('title is visible', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsVisible('title');
});

Or to ensure that a field is hidden you can pass the name to assertFormFieldIsHidden():

use function Pest\Livewire\livewire;

test('title is hidden', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsHidden('title');
});

Note that for both assertFormFieldIsHidden() and assertFormFieldIsVisible() you can pass the name of a specific form the field belongs to as the second argument like assertFormFieldIsHidden('title', 'createPostForm').

Disabled fields

To ensure that a field is enabled pass the name to assertFormFieldIsEnabled():

use function Pest\Livewire\livewire;

test('title is enabled', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsEnabled('title');
});

Or to ensure that a field is disabled you can pass the name to assertFormFieldIsDisabled():

use function Pest\Livewire\livewire;

test('title is disabled', function () {
    livewire(CreatePost::class)
        ->assertFormFieldIsDisabled('title');
});

Note that for both assertFormFieldIsEnabled() and assertFormFieldIsDisabled() you can pass the name of a specific form the field belongs to as the second argument like assertFormFieldIsEnabled('title', 'createPostForm').
