Why does code coverage give me 0 phpunit?

Question

PHP

Hello everyone, I continue to study PHPUnit and testing in general. I want to know the test coverage.
My code

<?php

namespace app;
class User2
{
    private $password;

    public function getPassword()
    {
        if (isset($this->password)) {
            return $this->password;
        } else {
            return null;
        }
    }

    public function setPassword($login)
    {
        if (is_string($login)) {
            $this->password = $this->cryptPassword($login);
            return true;
        }
        return false;
    }

    protected function cryptPassword($login)
    {
        return md5(uniqid($login));
    }
}

Test code

<?php

namespace tests;

use PHPUnit\Framework\TestCase;
use app\User2;

class User2Test extends TestCase
{
    public function invokeMethod(&$object, $methodName, array $parameters = [])
    {
        $reflection = new \ReflectionClass(get_class($object));
        $method = $reflection->getMethod($methodName);
        $method->setAccessible(true);
        return $method->invokeArgs($object, $parameters);
    }

    public function testGetPassword()
    {
        $obj = new User2();
        $login = 'login';
        $obj->setPassword($login);
        $this->assertEquals(32, strlen($obj->getPassword()));
    }

    public function testCryptPassword()
    {
        $obj = new User2();
        $login = 'login';
        $password = $this->invokeMethod($obj, 'cryptPassword', [$login]);
        $this->assertEquals(32, strlen($password));
    }
}

phpunit.xml

<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/6.5/phpunit.xsd"

         forceCoversAnnotation="true"
         beStrictAboutCoversAnnotation="true"
         beStrictAboutOutputDuringTests="true"
         beStrictAboutTodoAnnotatedTests="true"
         verbose="true"
        colors="true">
    <testsuite name="default">
        <directory suffix="Test.php">tests</directory>
    </testsuite>

    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">app</directory>
        </whitelist>
    </filter>
</phpunit>

I execute this command "phpunit --coverage-html tests\coverage" I open User2.php.html and I see

And in the console this is what

Please explain what I'm doing wrong. Thanks in advance!

English in black says that the tests are skipped and why they are skipped
