Laravel base_path() 给出错误 - 调用未定义的方法 baseDir()

Question

I have a tester class and I'm trying to use the global helper method base_path() , but I get the error below:

Error: Call to undefined method Illuminate\Container\Container::basePath()
/myproject/vendor/laravel/framework/src/Illuminate/Foundation/helpers.php:182
/myproject/tests/Feature/DataCsvSeedTest.php:31
/myproject/vendor/phpunit/phpunit/src/TextUI/Command.php:195
/myproject/vendor/phpunit/phpunit/src/TextUI/Command.php:148

Looks like helper.php in Laravel calls basePath(), and can't find it. Am I missing a namespace or some other setting for the global helper functions? Using Laravel 5.5.

<?php    
namespace Tests\Feature;
use Tests\TestCase;

class DataCsvSeedTest extends TestCase
{
   public function setUp()
   {
    $baseDir = base_path();
    print "basedir = ". $baseDir;
   }
}

Answer 1

Ah... This is a testClass,

class DataCsvSeedTest extends TestCase
{
   public function setUp()
   {
     parent::setUp();

     $baseDir = base_path();
     print "basedir = ". $baseDir;
   }
}

when you are overriding setUp() method don't forget to call the parent::Setup() , which will bootstrap the application.

Answer 2

You need to call parent::setUp before using basepath() because your laravel application needs to start first.

just add parent::setUp method before using basepath() .
