Testing a service in Symfony4 : class not found - php

Question

I want to test my service in Symfony 4 using phpunit bridge, but when i launch the test i get :
Error: Class 'App\Service\CompanyManager' not found
My service is located at src/Service/CompanyManager.php
tests/Service/CompanyManagerTest.php :
namespace App\Tests\Service;
use App\Service\CompanyManager;
use PHPUnit\Framework\TestCase;
use App\Entity\Company;
class CompanyManagerTest extends TestCase
{
public function testGetCompany()
{
$companyManager = new CompanyManager();
$company = $companyManager->getCompany(2);
$this->assertInstanceOf(Company::class,$company);
$company = $companyManager->getCompany(1000);
$this->assertNull($company);
}
}
In config/services_test.yaml, there is this statement :
# If you need to access services in a test, create an alias
# and then fetch that alias from the container. As a convention,
# aliases are prefixed with test. For example:
#
# test.App\Service\MyService: '#App\Service\MyService'
So i tried to add :
test.App\Service\CompanyManager: '#App\Service\CompanyManager'
But i still get the error :
$ ./vendor/bin/simple-phpunit tests
PHPUnit 5.7.27 by Sebastian Bergmann and contributors.
Testing tests
E 1 / 1
(100%)
Time: 364 ms, Memory: 4.00MB
There was 1 error:
1) App\Tests\Service\CompanyManagerTest::testGetCompany
Error: Class 'App\Service\CompanyManager' not found
C:\...\web\vp20\tests\Service\CompanyManagerTest.php:22
Line 22 is :
$companyManager = new CompanyManager();
Any idea ?
PS : sounds like someone has the same problem there : PHPUnit Error: Class not found

Answer 1

I have just had this problem.
Not sure why, but I didn't have a phpunit.xml.dist in the root of my project.
None of the examples shows this, but if you add bootstrap= and then include the autoloaded. It should start to find your classes.
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://schema.phpunit.de/6.0/phpunit.xsd"
bootstrap="vendor/autoload.php"

Answer 2

I think you should extend KernelTestCase (Symfony\Bundle\FrameworkBundle\Test\KernelTestCase) instead of TestCase

Answer 3

It is possible that a new class is not yet present in composers list. So... try to run
composer dump-autoload
I'll suggest to use this composer configuration
{
"autoload": {
"psr-4": {
"": ["src", "testS"]
}
}
}
Once you've defined this autoloading configuration in composer.json, and after a composer dump-autoload you should never have issues with autoloading.
