Testing
Overview
All examples in this guide will be written using Pest. However, you can easily adapt this to a PHPUnit.
Since all pages in the app are Livewire components, we're just using Livewire testing helpers everywhere. If you've never tested Livewire components before, please read this guide from the Livewire docs.
Getting started
Ensure that you are authenticated to access the app in your TestCase
:
protected function setUp(): void
{
parent::setUp();
$this->actingAs(User::factory()->create());
}
Resources
Pages
List
Routing & render
To ensure that the List page for the PostResource
is able to render successfully, generate a page URL, perform a request to this URL and ensure that it is successful:
it('can render page', function () {
$this->get(PostResource::getUrl('index'))->assertSuccessful();
});
Table
Filament includes a selection of helpers for testing tables. A full guide to testing tables can be found in the Table Builder documentation.
To use a table testing helper, make assertions on the resource's List page class, which holds the table:
use function Pest\Livewire\livewire;
it('can list posts', function () {
$posts = Post::factory()->count(10)->create();
livewire(PostResource\Pages\ListPosts::class)
->assertCanSeeTableRecords($posts);
});
Create
Routing & render
To ensure that the Create page for the PostResource
is able to render successfully, generate a page URL, perform a request to this URL and ensure that it is successful:
it('can render page', function () {
$this->get(PostResource::getUrl('create'))->assertSuccessful();
});
Creating
You may check that data is correctly saved into the database by calling fillForm()
with your form data, and then asserting that the database contains a matching record:
use function Pest\Livewire\livewire;
it('can create', function () {
$newData = Post::factory()->make();
livewire(PostResource\Pages\CreatePost::class)
->fillForm([
'author_id' => $newData->author->getKey(),
'content' => $newData->content,
'tags' => $newData->tags,
'title' => $newData->title,
])
->call('create')
->assertHasNoFormErrors();
$this->assertDatabaseHas(Post::class, [
'author_id' => $newData->author->getKey(),
'content' => $newData->content,
'tags' => json_encode($newData->tags),
'title' => $newData->title,
]);
});
Validation
Use assertHasFormErrors()
to ensure that data is properly validated in a form:
use function Pest\Livewire\livewire;
it('can validate input', function () {
livewire(PostResource\Pages\CreatePost::class)
->fillForm([
'title' => null,
])
->call('create')
->assertHasFormErrors(['title' => 'required']);
});
Edit
Routing & render
To ensure that the Edit page for the PostResource
is able to render successfully, generate a page URL, perform a request to this URL and ensure that it is successful:
it('can render page', function () {
$this->get(PostResource::getUrl('edit', [
'record' => Post::factory()->create(),
]))->assertSuccessful();
});
Filling existing data
To check that the form is filled with the correct data from the database, you may assertFormSet()
that the data in the form matches that of the record:
use function Pest\Livewire\livewire;
it('can retrieve data', function () {
$post = Post::factory()->create();
livewire(PostResource\Pages\EditPost::class, [
'record' => $post->getRouteKey(),
])
->assertFormSet([
'author_id' => $post->author->getKey(),
'content' => $post->content,
'tags' => $post->tags,
'title' => $post->title,
]);
});
Saving
You may check that data is correctly saved into the database by calling fillForm()
with your form data, and then asserting that the database contains a matching record:
use function Pest\Livewire\livewire;
it('can save', function () {
$post = Post::factory()->create();
$newData = Post::factory()->make();
livewire(PostResource\Pages\EditPost::class, [
'record' => $post->getRouteKey(),
])
->fillForm([
'author_id' => $newData->author->getKey(),
'content' => $newData->content,
'tags' => $newData->tags,
'title' => $newData->title,
])
->call('save')
->assertHasNoFormErrors();
expect($post->refresh())
->author_id->toBe($newData->author->getKey())
->content->toBe($newData->content)
->tags->toBe($newData->tags)
->title->toBe($newData->title);
});
Validation
Use assertHasFormErrors()
to ensure that data is properly validated in a form:
use function Pest\Livewire\livewire;
it('can validate input', function () {
$post = Post::factory()->create();
livewire(PostResource\Pages\EditPost::class, [
'record' => $post->getRouteKey(),
])
->fillForm([
'title' => null,
])
->call('save')
->assertHasFormErrors(['title' => 'required']);
});
Deleting
You can test the DeleteAction
using callAction()
:
use Filament\Actions\DeleteAction;
use function Pest\Livewire\livewire;
it('can delete', function () {
$post = Post::factory()->create();
livewire(PostResource\Pages\EditPost::class, [
'record' => $post->getRouteKey(),
])
->callAction(DeleteAction::class);
$this->assertModelMissing($post);
});
You can ensure that a particular user is not able to see a DeleteAction
using assertActionHidden()
:
use Filament\Actions\DeleteAction;
use function Pest\Livewire\livewire;
it('can not delete', function () {
$post = Post::factory()->create();
livewire(PostResource\Pages\EditPost::class, [
'record' => $post->getRouteKey(),
])
->assertActionHidden(DeleteAction::class);
});
View
Routing & render
To ensure that the View page for the PostResource
is able to render successfully, generate a page URL, perform a request to this URL and ensure that it is successful:
it('can render page', function () {
$this->get(PostResource::getUrl('view', [
'record' => Post::factory()->create(),
]))->assertSuccessful();
});
Filling existing data
To check that the form is filled with the correct data from the database, you may assertSet()
that the data in the form matches that of the record:
use function Pest\Livewire\livewire;
it('can retrieve data', function () {
$post = Post::factory()->create();
livewire(PostResource\Pages\ViewPost::class, [
'record' => $post->getRouteKey(),
])
->assertFormSet([
'author_id' => $post->author->getKey(),
'content' => $post->content,
'tags' => $post->tags,
'title' => $post->title,
]);
});
Relation managers
Render
To ensure that a relation manager is able to render successfully, mount the Livewire component:
use App\Filament\Resources\CategoryResource\Pages\EditCategory;
use function Pest\Livewire\livewire;
it('can render relation manager', function () {
$category = Category::factory()
->has(Post::factory()->count(10))
->create();
livewire(CategoryResource\RelationManagers\PostsRelationManager::class, [
'ownerRecord' => $category,
'pageClass' => EditCategory::class,
])
->assertSuccessful();
});
Table
Filament includes a selection of helpers for testing tables. A full guide to testing tables can be found in the Table Builder documentation.
To use a table testing helper, make assertions on the relation manager class, which holds the table:
use App\Filament\Resources\CategoryResource\Pages\EditCategory;
use function Pest\Livewire\livewire;
it('can list posts', function () {
$category = Category::factory()
->has(Post::factory()->count(10))
->create();
livewire(CategoryResource\RelationManagers\PostsRelationManager::class, [
'ownerRecord' => $category,
'pageClass' => EditCategory::class,
])
->assertCanSeeTableRecords($category->posts);
});
