How do you test code that uses BlockingQueue?

Testing code that utilizes BlockingQueue can be challenging due to its concurrent nature. However, you can use various approaches, such as mocking or implementing custom implementations to simulate behavior. Below is an example of how to test a class that uses a BlockingQueue.


        put("element1");
                $queue->put("element2");
    
                // Test that the queue size is as expected
                $this->assertEquals(2, $queue->size());
                
                // Remove an element
                $element = $queue->take();
                $this->assertEquals("element1", $element);
                $this->assertEquals(1, $queue->size());
            }
        }
        ?>
