Laravel Cache helper "driver" not implemented - php

Question

I have a test that is calling a Controller, which literally handles a call to some logic service I mocked.
The test
public function test_it_can_list_all_folders()
{
$mockedLogicResponse = [
"id" => 1111,
"parent_id" => 2222,
"name" => "Some Name",
"children" => [
[
"id" => 3333,
"parent_id" => 5555,
"name" => "Ad-hoc"
],
[
"id" => 4444,
"parent_id" => 6666,
"name" => "Another thing"
]
]
];
Cache::shouldReceive('has')
->once()
->with('campaign_folders')
->andReturn(false);
$this->instance(
Logic::class,
Mockery::mock(Logic::class, function (MockInterface $mock) use ($mockedLogicResponse) {
$mock->shouldReceive('fetchData')
->once()
->andReturn($mockedLogicResponse);
})
);
// httpGet is just a wrapper for a call('GET', ..), it's tested and working fine
$response = $this->httpGet($route);
$response->assertOk(); //This goes well
$this->assertEquals($mockedLogicResponse, $response->json()); //This goes well too
}
Controller:
class LogicController extends Controller {
protected $logic;
public function __construct(Logic $logic)
{
$this->logic = $logic;
}
public function index(Request $request)
{
$id = $request->get('folder_id');
return $this->logic->fetchData($id);
}
}
Logic:
class Logic {
public function fetchData(string $id): array
{
if (Cache::has('folders')) {
return Cache::get('folders');
}
//This is returning correctly the data
$foldersList = $this->getFolders(...);
foreach ($foldersList[$folder['id']] as $folder) {
$res = [....];
// We perform some irrelevant logic
$children = ['children' => $res[$folder['id']]];
$fetchedFolders[] = array_merge($folder, $children);
}
Cache::put('folders', $fetchedFolders, 3600);
return $fetchedFolders;
}
}
The problem(s) are a few, for starters I'm receiving this:
Mockery\Exception\BadMethodCallException : Received Mockery_2_Illuminate_Cache_CacheManager::driver(), but no expectations were specified
It's good to point out that I am literally copying an example from the documentation here Laravel docs, so I can't see I'm missing any step.
Also, as the Cache is being called from the mocked logic, but the method is calling them (I dumped the result of the "has" Cache method)
As I also want to test (In another test) that the Cache::get() is begin called when requested the data for a second time, how can I clean the Cache (I set it for an hour), in order to test something like so:
Cache::shouldReceive('has')->twice();
Cache::shouldReceive('get')->once();
Cache::shouldReceive('put')->once();
Is there any step I am missing? If so, which ones?
UPDATE: After googling a bit, I found this solution, which in part solves my testing issues, but I'm concerned why the official documentation is not working, in order to use it instead of a custom solution.
Kind regards
