Accessing callbacks on the interface PHPUnit\Framework\MockObject\MockObject suggest that you code against a concrete implementation. How about adding an instanceof check?

        $amqpChannel->expects($this->once())
            ->method('wait')
            ->with(null, false, 10)
            ->willReturnCallback(function ($allowedMethods, $nonBlocking, $waitTimeout) use ($consumer) {
                // simulate time passing by moving the last activity date time
                $consumer->setLastActivityDateTime(new \DateTime("-$waitTimeout seconds"));
                throw new AMQPTimeoutException();
            });

        $this->assertEquals(2, $consumer->consume(1));
    }
}
