Laravel: assertDatabaseHas - unexpected fail - laravel

Question

I don't understand why this database test fails. I'm aware that i don't assert on the created_at and updated_at columns, but the three columns (id, user_id, thing_id) should be enough and i'm sure that i have tested on just a selection of columns before, and it has worked!
What am i missing?
Failed asserting that a row in the table [thing_history] matches the attributes [
{
"id": 1,
"user_id": 1,
"thing_id": 1
},
{
"id": 2,
"user_id": 1,
"thing_id": 2
},
{
"id": 3,
"user_id": 1,
"thing_id": 3
}
].
Found: [
{
"id": "1",
"user_id": "1",
"thing_id": "1",
"created_at": "2019-02-01 21:18:17",
"updated_at": "2019-02-01 21:18:17"
},
{
"id": "2",
"user_id": "1",
"thing_id": "2",
"created_at": "2019-02-01 21:18:17",
"updated_at": "2019-02-01 21:18:17"
},
{
"id": "3",
"user_id": "1",
"thing_id": "3",
"created_at": "2019-02-01 21:18:17",
"updated_at": "2019-02-01 21:18:17"
}
]
This is the test code
/** #test */
public function retrieving_feed_creates_history()
{
$user = factory('App\User')->create();
$this->actingAs($user);
factory('App\Thing', 3)->create();
$response = $this->json('GET', '/api/thing/feed/all');
$this->assertDatabaseHas('feed_histories', [
[
'id' => 1,
'thing_id' => 1,
'user_id' => $user->id,
],
[
'id' => 2,
'thing_id' => 2,
'user_id' => $user->id,
],
[
'id' => 3,
'thing_id' => 3,
'user_id' => $user->id,
]
]);
}
This is the migration code:
public function up()
{
Schema::create('feed_histories', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id');
$table->integer('thing_id');
$table->timestamps();
});
}

Answer 1

Seems like i have misunderstood something. To check several rows, i have to split the test into into separate assertions for each row.
This works fine:
$this->assertDatabaseHas('feed_histories', [
'thing_id' => $thingA->id,
'user_id' => $user->id,
]);
$this->assertDatabaseHas('feed_histories', [
'thing_id' => $thingB->id,
'user_id' => $user->id,
]);

Answer 2

Yeah, the map of multiple records fails as assertDatabaseHas function currently only handles a single row by mapping a single row in the where clause...
To get a better insight, you can have a look at the base function of assertDatabaseHas
public function matches($table): bool
{
return $this->database->table($table)->where($this->data)->count() > 0;
}
here, the $this->data refers to the second argument of assertDatabaseHas funciton
So, it clears out our doubt of why we can't pass array of arrays.
