• Laravel Version: 5.8.21
• PHP Version: 7.1
• Database Driver & Version: doesn't matter

Description:

Declaration of Illuminate\Foundation\Testing\Assert::assertArraySubset($subset, $array, bool $checkForObjectIdentity = false, string $message = ''): void should be compatible with PHPUnit\Framework\Assert::assertArra ySubset($subset, $array, $strict = false, $message = '')

Steps To Reproduce:

[devcircus]

PHPUnit updated the signature to that function in version 7.4, so you must be using PHPUnit <= 7.3.5. Laravel 5.8 requires at least PHPUnit 7.5.
