How to create a phpUnit test for such a class?

Question

PHP

Good afternoon, please tell me how to create a phpunit test for this class, if not difficult? I'm new to this ( https://pastebin.com/udQQL5hk ) I was tormented for half a night and could not figure out how to build this test correctly

Answer 1

class TestTest {
    public function testGetExact() {
        $str = '*строка для тестирования*';
        $expected = '*посчитанный результат*';
        $this->assertEquals($expected, Test::getExact($str));
    }
}
