Laravel extending Illuminate \ Foundation \ Testing \ TestCase with custom namespace

I am trying to set up unit tests for my Laravel API (5.2) project. Before using the unit tests, I would like to define their own namespace for them, so I created namespace Test;

in the TestCase.php

default file . For example:

namespace Test;

class TestCase extends Illuminate\Foundation\Testing\TestCase
{
  ...
}

      

        
        
        
      

    

Then I created a folder UnitTests

in a folder tests

and put my unit tests in that folder with the following namespace:

namespace Test\UnitTests;

use Test\TestCase;

class CreateAccountTest extends TestCase
{
  ...
}

      

        
        
        
      

    

Now when I want to run my unit tests I get the following error:

PHP Fatal error: Class 'Test\Illuminate\Foundation\Testing\TestCase' not found in /var/www/ops/tests/TestCase.php on line 6

Thus, Laravel assumes that the class Illuminate\Foundation\Testing\TestCase

is in the Test namespace instead Illuminate

of the Laravel namespace .

I also have the following autoload set up in the file composer.json

:

"autoload": {
    "classmap": [
        "database",
        "tests"
    ],
    "psr-4": {
        "App\\": "app/",
        "Test\\": "tests/"
    }
},
"autoload-dev": {
    "classmap": [
        "tests/TestCase.php"
    ]
}

      

        
        
        
      

    

I have also tried both commands without success:

• php artisan config:cache
  
  
• composer dump-autoload
