unable to call parent::setUp() and causes whole test suite break

[nomadbard916]

Laravel version: 5.8 PHP version: 7.2.19 phpunit version: 7.5.17 OS: Windows 10 professional 1809 Node.js version: 12

I got a test file that calls setUp() at the very beginning with calling setUp() in TestCase. When I run all the tests with this extension, the first error was "ReflectionException: Class env does not exist", making all next tests unfunctional with the same exception.
