As investigated in infection/infection#1736, coverage for closures doesn't seem to be picked up correctly, when using PHPDBG.
Specifically, PCOV works as expected:
A coverage report done with phpdbg -qrr will instead produce partial coverage:
Reproducible example
<?php
declare(strict_types=1);
final class Foo
{
/** @return callable(): int */
function make(): callable
{
return static function (): int {
return 1;
};
}
}<?php
declare(strict_types=1);
require_once __DIR__ . '/../../src/Foo.php';
/** @covers Foo */
final class FooTest extends \PHPUnit\Framework\TestCase
{
function testClosure(): void
{
self::assertSame(1, (new Foo())->make()());
}
}PHPDBG output

PHPDBG + PCOV = 💥
Note: running phpdbg with pcov installed will lead to a segfault:
