Gitlab CI -Laravel 5.5 - PHPUnit "Tests\TestCase not found" - php

Question

I set up a Gitlab CI Pipeline for a Laravel 5.5 project (files at the bottom of the post) and the build is succeeding, but the tests fail because PHPUnit exits with the error message
Fatal error: Class 'Tests\TestCase' not found in /builds/[User]/[Repo]/tests/Feature/DocumentTest.php on line 8
(Obviously, [User] and [Repo] aren't the real values, just don't wanna make it public here)
I've tried different things already, like installing PHPUnit globally, calling PHPUnit in different ways, it all ends up with the same error message.
PHPUnit is running successfully on my local (no matter HOW I call it, it always works). So anyone knows what the problem here might be?
For reference here are the pipeline files:

Answer 1

What is Tests\TestCase? I'm guessing line 8 in DocumentTest.php is
public class DocumentTest extends TestCase
...where TestCase is PHPUnit\Framework\TestCase. It seems like there's an autoloading problem or the file doesn't import TestCase. Try changing this line to:
public class DocumentTest extends PHPUnit_Framework_TestCase
I can try to give a better answer if you include the phpunit.xml and composer.json.

I got the same error on local though. Make sure your composer.json has
"psr-4": {
"App\\": "app/",
"Tests\\": "tests/"
},
run composer dump-autoload at least once or make it a part of your testing procedure.
