Testing Laravel Nova - laravel

Question

Currently I'm trying to write feature tests for laravel nova that assert that the page is loaded correctly and data can be seen.
However when I write the tests I can't find a way to assert that the correct text is shown due to way laravel nova's data is produce. Ontop of that I can't seem to test if a page loads correctly with laravel nova's 404 page coming back as a 200 response when a resource page that doesn't exist loads.
Has anyone found a good way to feature test nova?

Answer 1

TL;DR: check out this repo: https://github.com/bradenkeith/testing-nova. It has helped me find my way on how to test Laravel Nova.
Laravel Nova is basically a CRUD framework. So I'm assuming that, when you say
"that the page is loaded correctly and data can be seen"
You actually mean: my resources are loaded correctly. Or, I can create/update/delete a resource. This is because Nova is loading its resource info asynchronous via api calls.
So that's why, a good method to test your logic is to test the /nova-api/ routes.
For example:
<?php
namespace Tests\Feature\Nova;
use App\Note;
use Tests\TestCase;
class NoteTest extends TestCase
{
public function setUp(): void
{
parent::setUp();
}
/** #test */
public function it_gets_a_note()
{
// given
$note = factory(Note::class)->create();
$response = $this->get('/nova-api/notes/' . $note->id)
->assertStatus(200)
->assertJson([
'resource' => [
'id' => [
'value' => $note->id
]
]
]);
}
}
By calling the route https://my-app.test/resources/notes/1, we can assert that we're getting a 200 response (successful) and that we're actually returning our newly created Note. This is a pretty trustworthy test to be sure a resource detail page is working fine.
If, however, you are talking about Browser Testing, you might want to take a look at Laravel Dusk:
Laravel Dusk provides an expressive, easy-to-use browser automation and testing API.
Once installed, you can start real browser testing:
$user = factory(User::class)->create();
$user->assignRole('admin');
$this->browse(function (Browser $browser) use ($user) {
$browser
->loginAs($user)
->visit('/')
->assertSee('Dashboard');
});

I had the same issue, I found out that the gate in App\Providers\NovaServiceProvider.php is not letting users pass, just return true when testing only and everything must work as expected
protected function gate()
{
Gate::define('viewNova', function ($user) {
return true;
});
}

Add on app/config file in your project directory:
App\Providers\NovaServiceProvider::class,
