Test class not found when extending abstract test class - php

Question

I am currently using the lumen framework (v5.6) and writing unit tests for my code.
I have a base class TestCase:
namespace Tests;
$_SERVER["http_proxy"] = "";
abstract class TestCase extends \Laravel\Lumen\Testing\TestCase
{
/**
* Creates the application.
*
* #return \Laravel\Lumen\Application
*/
public function createApplication()
{
return require __DIR__.'/../bootstrap/app.php';
}
}
I use this base class to write my tests, however I have two tests with a lot of overlap (they both test implementations of an interface), so I put the common logic in an abstract class:
namespace Tests\App\IO;
use App\io\PageDataParser;
use App\Models\AdvancedArray;
use App\Services\PageService;
use Mockery;
use Tests\TestCase;
abstract class ParsePageDataTestCase extends TestCase
{
// Test logic here, but not relevant for the question
}
And finally I use this abstract class on my actual test:
namespace Tests\App\IO;
use App\io\JsonPageDataParser;
use App\Models\AdvancedArray;
class JsonParsePageDataTestCaseTest extends ParsePageDataTestCase
{
// Test are here, but not relevant for the question
}
However when I execute JsonParsePageDataTestCaseTest I get the following error:
PHP Fatal error: Class 'Tests\ParsePageDataTestCase' not found in \tests\app\io\JsonParsePageDataTest.php on line 15
I have verified that the structure of the folders is corrected, also tried using 'composer dump-autoloadand verified that mycomposer.jsonhas an entry which specifies a classmap to 'tests/.
I execute my tests using phpunit.xml which loads the bootstrap/app.php, but I still get this error.
The phpunit.xml:
<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
backupStaticAttributes="false"
bootstrap="bootstrap/app.php"
colors="true"
convertErrorsToExceptions="true"
convertNoticesToExceptions="true"
convertWarningsToExceptions="true"
processIsolation="false"
stopOnFailure="false">
<testsuites>
<testsuite name="Application test Suite">
<directory suffix="Test.php">./tests</directory>
</testsuite>
</testsuites>
<filter>
<whitelist processUncoveredFilesFromWhitelist="true">
<directory suffix=".php">./app</directory>
</whitelist>
</filter>
<php>
<!-- ENV variables go here -->
</php>
</phpunit>
And finally my composer.json:
{

"keywords": ["framework", "laravel", "lumen"],

If you need any more information please let me know.
Thank you in advance!

This is a problem from the Lumen installation.
When you install laravel the tests folder comes configured as psr-4 on autoload-dev:
{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
...
"autoload-dev": {
"psr-4": {
"Tests\\": "tests/"
}
},
...
"minimum-stability": "dev",
"prefer-stable": true
}
But on Lumen installation doesn't as we can see bellow:
{
"name": "laravel/lumen",
"description": "The Laravel Lumen Framework.",
"keywords": ["framework", "laravel", "lumen"],
"license": "MIT",
"type": "project",
"require": {
"php": ">=7.1.3",
"laravel/lumen-framework": "5.7.*",
"vlucas/phpdotenv": "~2.2"
},
"require-dev": {
"fzaninotto/faker": "~1.4",
"phpunit/phpunit": "~7.0",
"mockery/mockery": "~1.0"
},
"autoload": {
"classmap": [
"database/seeds",
"database/factories"
],
"psr-4": {
"App\\": "app/"
}
},
"autoload-dev": {
"classmap": [
"tests/"
]
},
"scripts": {
"post-root-package-install": [
"#php -r \"file_exists('.env') || copy('.env.example', '.env');\""
]
},
"config": {
"preferred-install": "dist",
"sort-packages": true,
"optimize-autoloader": true
},
"minimum-stability": "dev",
"prefer-stable": true
}
So in order for this to work you will need to change the autoload to:
"autoload-dev": {
"classmap": [
"tests/"
],
"psr-4": {
"Tests\\": "tests/"
}
}
