php - Unit testing with the config app file in Laravel -

my model method relies on config() global, here;

public function getgroup() {     if(config('app.pages.'.$this->group.'.0')) {         return $this->group;     }     return "city"; } 

i trying test method in unit test class, here;

public function testgetgroupreturnscityasdefault() {     $response = new response();     $response->group = "town";     $test = $response->getgroup();     dd($test); } 

the error is;

error: call member function make() on null /home/vagrant/sites/vendor/laravel/framework/src/illuminate/foundation/helpers.php:62 /home/vagrant/sites/vendor/laravel/framework/src/illuminate/foundation/helpers.php:163 

i know related config() global. not sure how set in test. tried

public function setup() { config(['app.pages' => [     'city' => [........ 

but got same error. how can set up?

i'm not sure if have solved yet had similar issue.

there 2 things had work:

1) make sure calling setup parent method so:

public function setup() {     parent::setup();      // other stuff } 

2) make sure test class extending laravel testcase rather phpunit_framework_testcase

brief explanation: error getting because containerinstance of laravel null since going through phpunit , such never created. if above steps you'll ensure laravel first instantiate container instance.

p.s. if going end referencing env variables, should phpunit.xmlsection enviornment variables.
