How to fix api json delete request - json

Question

In following code, I'm trying to create a new category (name = 'To be deleted') and then I want to delete it.
first part of the code working fine and I can see new record in the database every time I run the unit test
but I'm having a problem with recode deletion. what's wrong with my code
public function testCategoryDeletion()
{
$user = \App\User::find(1);
//dd($user->name);
$category = \App\Category::create(['name' => 'To be deleted']);
//dd($category->id);
$response = $this->actingAs($user, 'api')
->json('DELETE', "/api/category/{$category->id}")
->assertStatus(200)->assertJson([
'status' => true,
'message' => 'Category Deleted',
]);
}
Test case output

I fixed the controller as follows and now its working,
public function destroy(Category $category)
{
$status = $category->delete();
return response()->json([
'status' => $status,
'message' => $status ? 'Category Deleted' : 'Error Deleting Category'
]);
}
API routes
Route::group(['middleware' => 'auth:api'], function(){
Route::resource('/task', 'TaskController');
Route::resource('/category', 'CategoryController');
Route::get('/category/{category}/tasks', 'CategoryController#tasks');
});
