Testing

Create a test component inside the tests folder in your application, for example tests/Feature/Livewire/UsersTableTest.php

Pest Browser Testing

Pest Browser Testing allows you to simulate authentic user interactions within your application—including clicking elements, typing input, and selecting options in real time.

The next example tests a dishes table, ensuring that clicking and typing in the filter field will perform the search query and return the expected records.

//tests/Browser/FilterFieldTest.php

$searchField = '[wire\:model\.live\.debounce\.700ms="search"]';

it('can filter by existing record')
    ->withVite() //enable Vite for this test
    ->visit('/dishes')
    ->assertSee('Arkansas Possum Pie')
    ->fill($searchField, 'Bacalhau')
    ->assertDontSee('Arkansas Possum Pie')
    ->assertSee('Bacalhau com natas');

Here, we guarantee the row "Arkansas Possum Pie" is visible when the page loads. Then, we simulate a click in the filter and typing the word "Bacalhau". As a result, we ensure that "Arkansas Possum Pie" is not visible anymore, while the row "Bacalhau com natas" is visible.

Liveware Testing

You should follow the same concept defined in the livewire documentation, and then you will be able to use other native assertions in PowerGrid:

Testing Actions Buttons

Reference: action button

PowerGrid provides a simple testing utility to ensure that a button's structure complies with standards for later rendering with JavaScript.

See this example.

Component: UsersTable

class UsersTable extends PowerGridComponent {
    // ...
    
    public function datasource(): Collection
    {
        return collect([
            [
                'id'         => 29,
                'name'       => 'Luan',
                'balance'    => 241.86,
                'is_online'  => true,
                'created_at' => '2023-01-01 00:00:00',
            ],
            [
                'id'         => 57,
                'name'       => 'Daniel',
                'balance'    => 166.51,
                'is_online'  => true,
                'created_at' => '2023-02-02 00:00:00',
            ],
            [
                'id'         => 93,
                'name'       => 'Claudio',
                'balance'    => 219.01,
                'is_online'  => false,
                'created_at' => '2023-03-03 00:00:00',
            ],
            [
                'id'         => 104,
                'name'       => 'Vitor',
                'balance'    => 44.28,
                'is_online'  => true,
                'created_at' => '2023-04-04 00:00:00',
            ],
        ]);
    }

    public function actions($row): array
    {
        return [
            Button::add('view')
                ->icon('default-eye', [
                    'class' => '!text-green-500',
                ])
                ->slot('View')
                ->class('text-slate-500 flex gap-2 hover:text-slate-700 hover:bg-slate-100 font-bold p-1 px-2 rounded')
                ->dispatch('clickToEdit', ['dishId' => $row?->id, 'dishName' => $row?->name]),
        ];
    }
};

Component Test: UsersTableTest.php

assertHasAction

it('should be able to see "view" action', function (string $component, object $params) {
    livewire(UsersTableTest::class)
        ->assertHasAction('view')
        // other assertions;
})

assertActionContainsAttribute

class attribute example:

it('should be able to see "class" attribute in "view" action', function (string $component, object $params) {
    livewire(UsersTableTest::class)
        ->assertActionContainsAttribute(
            action: 'view', 
            attribute: 'class', 
            expected: 'flex gap-2 hover:text-slate-700'
        )
        // other assertions;
})

assertActionContainsAttribute

wire:click attribute example:

it('should be able to see "wire:click" in "view" action', function (string $component, object $params) {
    livewire(UsersTableTest::class)
        ->assertActionContainsAttribute(
            action: 'view', 
            attribute: 'wire:click', 
            expected: 'clickToEdit',
            expectedParams: ['dishId' => 29, 'dishName' => 'Luan']
        )
        // other assertions;
})

assertActionHasIcon

icon example:

it('should be able to see "wire:click" in "view" action', function (string $component, object $params) {
    livewire(UsersTableTest::class)
        ->assertActionContainsAttribute(
            action: 'view', 
            icon: 'default-eye', 
            expected: '!text-green-500'
        )
