Overview

All examples in this guide will be written using Pest. To use Pest’s Livewire plugin for testing, you can follow the installation instructions in the Pest documentation on plugins: Livewire plugin for 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(),
        // ...
    ]);

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),
        ]);
});

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

You may also find it useful to pass a function to the assertFormSet() method, which allows you to access the form $state and perform additional assertions:

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

it('can automatically generate a slug from the title without any spaces', function () {
    $title = fake()->sentence();

    livewire(CreatePost::class)
        ->fillForm([
            'title' => $title,
        ])
        ->assertFormSet(function (array $state): array {
            expect($state['slug'])
                ->not->toContain(' ');
                
            return [
                'slug' => Str::slug($title),
            ];
        });
});

You can return an array from the function if you want Filament to continue to assert the form state after the function has been run.

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,
        ])
        ->call('create')
        ->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('create')
    ->assertHasNoFormErrors();

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();
});

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 $field->isDisabled();
        });
});

To assert that a form does not have a given field, pass the field name to assertFormFieldDoesNotExist():

use function Pest\Livewire\livewire;

it('does not have a conditional field', function () {
    livewire(CreatePost::class)
        ->assertFormFieldDoesNotExist('no-such-field');
});

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');
});

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');
});

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').

Layout components

If you need to check if a particular layout component exists rather than a field, you may use assertFormComponentExists(). As layout components do not have names, this method uses the key() provided by the developer:

use Filament\Forms\Components\Section;

Section::make('Comments')
    ->key('comments-section')
    ->schema([
        //
    ])

use function Pest\Livewire\livewire;

test('comments section exists', function () {
    livewire(EditPost::class)
        ->assertFormComponentExists('comments-section');
});

To assert that a form does not have a given component, pass the component key to assertFormComponentDoesNotExist():

use function Pest\Livewire\livewire;

it('does not have a conditional component', function () {
    livewire(CreatePost::class)
        ->assertFormComponentDoesNotExist('no-such-section');
});

To check if the component exists and passes a given truth test, you can pass a function to the second argument of assertFormComponentExists(), returning true or false if the component passes the test or not:

use Filament\Forms\Components\Component;

use function Pest\Livewire\livewire;

test('comments section has heading', function () {
    livewire(EditPost::class)
        ->assertFormComponentExists(
            'comments-section',
            function (Component $component): bool {
                return $component->getHeading() === 'Comments';
            },
        );
});

If you want more informative test results, you can embed an assertion within your truth test callback:

use Filament\Forms\Components\Component;
use Illuminate\Testing\Assert;

use function Pest\Livewire\livewire;

test('comments section is enabled', function () {
    livewire(EditPost::class)
        ->assertFormComponentExists(
            'comments-section',
            function (Component $component): bool {
                Assert::assertTrue(
                    $component->isEnabled(),
                    'Failed asserting that comments-section is enabled.',
                );
                
                return true;
            },
        );
});

Wizard

To go to a wizard’s next step, use goToNextWizardStep():

use function Pest\Livewire\livewire;

it('moves to next wizard step', function () {
    livewire(CreatePost::class)
        ->goToNextWizardStep()
        ->assertHasFormErrors(['title']);
});

You can also go to the previous step by calling goToPreviousWizardStep():

use function Pest\Livewire\livewire;

it('moves to next wizard step', function () {
    livewire(CreatePost::class)
        ->goToPreviousWizardStep()
        ->assertHasFormErrors(['title']);
});

If you want to go to a specific step, use goToWizardStep(), then the assertWizardCurrentStep method which can ensure you are on the desired step without validation errors from the previous:

use function Pest\Livewire\livewire;

it('moves to the wizards second step', function () {
    livewire(CreatePost::class)
        ->goToWizardStep(2)
        ->assertWizardCurrentStep(2);
});

If you have multiple forms on a single Livewire component, any of the wizard test helpers can accept a formName parameter:

use function Pest\Livewire\livewire;

it('moves to next wizard step only for fooForm', function () {
    livewire(CreatePost::class)
        ->goToNextWizardStep(formName: 'fooForm')
        ->assertHasFormErrors(['title'], formName: 'fooForm');
});

Actions

You can call an action by passing its form component name, and then the name of the action to callFormComponentAction():

use function Pest\Livewire\livewire;

it('can send invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->callFormComponentAction('customer_id', 'send');

    expect($invoice->refresh())
        ->isSent()->toBeTrue();
});

To pass an array of data into an action, use the data parameter:

use function Pest\Livewire\livewire;

it('can send invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->callFormComponentAction('customer_id', 'send', data: [
            'email' => $email = fake()->email(),
        ])
        ->assertHasNoFormComponentActionErrors();

    expect($invoice->refresh())
        ->isSent()->toBeTrue()
        ->recipient_email->toBe($email);
});

If you ever need to only set an action’s data without immediately calling it, you can use setFormComponentActionData():

use function Pest\Livewire\livewire;

it('can send invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->mountFormComponentAction('customer_id', 'send')
        ->setFormComponentActionData([
            'email' => $email = fake()->email(),
        ])
});

Execution

To check if an action has been halted, you can use assertFormComponentActionHalted():

use function Pest\Livewire\livewire;

it('stops sending if invoice has no email address', function () {
    $invoice = Invoice::factory(['email' => null])->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->callFormComponentAction('customer_id', 'send')
        ->assertFormComponentActionHalted('customer_id', 'send');
});

Errors

assertHasNoFormComponentActionErrors() is used to assert that no validation errors occurred when submitting the action form. To check if a validation error has occurred with the data, use assertHasFormComponentActionErrors(), similar to assertHasErrors() in Livewire:

use function Pest\Livewire\livewire;

it('can validate invoice recipient email', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->callFormComponentAction('customer_id', 'send', data: [
            'email' => Str::random(),
        ])
        ->assertHasFormComponentActionErrors(['email' => ['email']]);
});

To check if an action is pre-filled with data, you can use the assertFormComponentActionDataSet() method:

use function Pest\Livewire\livewire;

it('can send invoices to the primary contact by default', function () {
    $invoice = Invoice::factory()->create();
    $recipientEmail = $invoice->company->primaryContact->email;

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->mountFormComponentAction('customer_id', 'send')
        ->assertFormComponentActionDataSet([
            'email' => $recipientEmail,
        ])
        ->callMountedFormComponentAction()
        ->assertHasNoFormComponentActionErrors();
        
    expect($invoice->refresh())
        ->isSent()->toBeTrue()
        ->recipient_email->toBe($recipientEmail);
});

Action state

To ensure that an action exists or doesn’t in a form, you can use the assertFormComponentActionExists() or assertFormComponentActionDoesNotExist() method:

use function Pest\Livewire\livewire;

it('can send but not unsend invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertFormComponentActionExists('customer_id', 'send')
        ->assertFormComponentActionDoesNotExist('customer_id', 'unsend');
});

To ensure an action is hidden or visible for a user, you can use the assertFormComponentActionHidden() or assertFormComponentActionVisible() methods:

use function Pest\Livewire\livewire;

it('can only print customers', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertFormComponentActionHidden('customer_id', 'send')
        ->assertFormComponentActionVisible('customer_id', 'print');
});

To ensure an action is enabled or disabled for a user, you can use the assertFormComponentActionEnabled() or assertFormComponentActionDisabled() methods:

use function Pest\Livewire\livewire;

it('can only print a customer for a sent invoice', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertFormComponentActionDisabled('customer_id', 'send')
        ->assertFormComponentActionEnabled('customer_id', 'print');
});

To check if an action is hidden to a user, you can use the assertFormComponentActionHidden() method:

use function Pest\Livewire\livewire;

it('can not send invoices', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertFormComponentActionHidden('customer_id', 'send');
});

Button appearance

To ensure an action has the correct label, you can use assertFormComponentActionHasLabel() and assertFormComponentActionDoesNotHaveLabel():

use function Pest\Livewire\livewire;

it('send action has correct label', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertFormComponentActionHasLabel('customer_id', 'send', 'Email Invoice')
        ->assertFormComponentActionDoesNotHaveLabel('customer_id', 'send', 'Send');
});

To ensure an action’s button is showing the correct icon, you can use assertFormComponentActionHasIcon() or assertFormComponentActionDoesNotHaveIcon():

use function Pest\Livewire\livewire;

it('when enabled the send button has correct icon', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertFormComponentActionEnabled('customer_id', 'send')
        ->assertFormComponentActionHasIcon('customer_id', 'send', 'envelope-open')
        ->assertFormComponentActionDoesNotHaveIcon('customer_id', 'send', 'envelope');
});

To ensure that an action’s button is displaying the right color, you can use assertFormComponentActionHasColor() or assertFormComponentActionDoesNotHaveColor():

use function Pest\Livewire\livewire;

it('actions display proper colors', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertFormComponentActionHasColor('customer_id', 'delete', 'danger')
        ->assertFormComponentActionDoesNotHaveColor('customer_id', 'print', 'danger');
});

URL

To ensure an action has the correct URL, you can use assertFormComponentActionHasUrl(), assertFormComponentActionDoesNotHaveUrl(), assertFormComponentActionShouldOpenUrlInNewTab(), and assertFormComponentActionShouldNotOpenUrlInNewTab():

use function Pest\Livewire\livewire;

it('links to the correct Filament sites', function () {
    $invoice = Invoice::factory()->create();

    livewire(EditInvoice::class, [
        'invoice' => $invoice,
    ])
        ->assertFormComponentActionHasUrl('customer_id', 'filament', 'https://filamentphp.com/')
        ->assertFormComponentActionDoesNotHaveUrl('customer_id', 'filament', 'https://github.com/filamentphp/filament')
        ->assertFormComponentActionShouldOpenUrlInNewTab('customer_id', 'filament')
        ->assertFormComponentActionShouldNotOpenUrlInNewTab('customer_id', 'github');
});
