            Call::create('format')
                ->with(new ArgumentInstanceOf(\DateTime::class), 'c'),
                ->willReturn('2004-02-12T15:19:21+00:00')
            Call::create('format')
                ->with(
                    new ArgumentCallback(function ($dateTime) {
                        self::assertInstanceOf(\DateTime::class, $dateTime);

        self::assertSame('2004-02-12T15:19:21+00:00' , $dateTimeService->format(new \DateTime(), 'c'));
        self::assertSame('2008-05-23T08:12:55+00:00' , $dateTimeService->format(new \DateTime(), 'c'));
    }

FAQ

Expectation failed for method name is anything when invoked <n...> time(s).

There is a mock with $calls given, but no method get called on the mock.

/** @var User|MockObject $user */
$user = $this->getMockByCalls(User::class, [
    Call::create('getId')->with()->willReturn('a656cca7-7363-4ba7-875d-74bb0fd4f543'),
]);

// uncomment and test will be green
//$user->getId();
