Why PHPUnit Into Laravel Return "No Tests Executed!" At Execution Feature Tests

I have file tests/Feature/InvoicePaymentTest.php, he contains are three tests. First and second are tests is executed correctly. Third test has return "No tests executed!", and not return error.

My code scheme

<?php

namespace Tests\Feature;

// use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;

class SubscriptionInvoicePaymentTest extends TestCase
{

    public function testFirst()
    {
        // this test correctly exeqted
    }

    public function testSecond()
    {
        // this test correctly exeqted
    }

    public function nextPaymentTest()
    {
        // this test return "No tests executed!" as seen in the screenshot
    }
}

My phpunit.xml

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"

    </php>
</phpunit>

What could be the problem? Thank you in advance

In phpunit a method should be either prefixed with test or have the @test annotation in order to be run.
