<?php
use PHPUnit\Framework\TestCase;
use equal\test\Tester;
include('eq.lib.php');

final class CoverageTest extends TestCase {

    public function test(): void {
        $tests_path = "packages/core/tests";
        if(is_dir($tests_path)) {
            foreach (glob($tests_path."/*.php") as $filename) {
                include($filename);
                $tester = new Tester($tests);
                $tester->test()->toArray();
            }
        }
        $this->assertTrue(true);
    }
