# Test-case

# Before running test case, python should be installed on host machine.

STEP 1 - 
- create sender.py file to send message with below contents
 
import pika

credentials = pika.PlainCredentials('rabbitmq', 'rabbitmq')
# Replace '5672' with the correct port number if RabbitMQ is using a different port.
connection = pika.BlockingConnection(pika.ConnectionParameters('10.105.202.189', 5672, '/', credentials))

channel = connection.channel()

channel.queue_declare(queue='test_queue')

channel.basic_publish(exchange='', routing_key='test_queue', body='Hello, RabbitMQ!')
print("Message Sent")

connection.close()


- create receiver.py file to recieve message with below contents

import pika

def callback(ch, method, properties, body):
    print("Received:", body)

credentials = pika.PlainCredentials('rabbitmq', 'rabbitmq')
# Replace '5672' with the correct port number if RabbitMQ is using a different port.
connection = pika.BlockingConnection(pika.ConnectionParameters('10.105.202.189', 5672, '/', credentials))
channel = connection.channel()

channel.queue_declare(queue='test_queue')

channel.basic_consume(queue='test_queue', on_message_callback=callback, auto_ack=True)

print('Waiting for messages. To exit press CTRL+C')
channel.start_consuming()

STEP 2 - update below line with correct details in both files

credentials = pika.PlainCredentials('<username>', '<password>')
# Replace '5672' with the correct port number if RabbitMQ is using a different port.
connection = pika.BlockingConnection(pika.ConnectionParameters('<service-ip>', <port>, '/', credentials))

STEP 3 - open two terminals side by side, and run both scripts in separate terminal with below commands
python 3 sender.py ---------(on left side terminal)
pythin 3 receiver.py -------(on right side terminal)

STEP 4 - you will get message on left terminal as below

$python3 reciever.py
Waiting for messages. To exit press CTRL+C
Received: b'Hello, RabbitMQ!'
