Laravel - HTTP Tests - Asserting Against Json Collections

Often, your route will return a JSON response that contains multiple items, such as multiple users:

    Route::get('/users', function () {
        return User::all();

In these situations, we may use the fluent JSON object's has method to make assertions against the users included in the response. For example, let's assert that the JSON response contains three users. Next, we'll make some assertions about the first user in the collection using the first method. The first method accepts a closure which receives another assertable JSON string that we can use to make assertions about the first object in the JSON collection:

        ->assertJson(fn (AssertableJson $json) =>
                 ->first(fn ($json) =>
                    $json->where('id', 1)
                         ->where('name', 'Victoria Faith')
