[12.x] Iterable models assertion

[DarkGhostHunter]

What?

Makes assertDatabaseHas, assertDatabaseMissing, assertSoftDeleted, assertNotSoftDeleted and their aliases support an iterable set of Models (like an array or an Eloquent Collection), which avoids having a loop or multiple assertions.

use App\Models\Article;

$articles = Article::factory(10)->create();

// Before
array_map($this->assertDatabaseHas(...), $articles->all());


// After
$this->assertDatabaseHas($articles);

If a method like assertDatabaseHas is issued with $data and $connection, that will be shared across all the model assertions, as it should be expected:

use App\Models\Article;

$articles = Article::factory(10)->create();

// Before
foreach ($articles as $article) {
    $this->assertDatabaseHas($article, ['is_published' => true])
}

// After
$this->assertDatabaseHas($articles, ['is_published' => true]);
