Testing SQS queues

1. Deploying the stack

You can choose to deploy using either AWS SAM or AWS CDK (but not both as the way I've named the AWS resources will conflict with each other).

To deploy using SAM

Note: The following assumes you have the SAM CLI installed.

sam build
sam deploy --guided

To deploy using CDK

Note: The following assumes you have Node and Npm (Node Package Manager) installed. Also, It's best not to install AWS CDK and to make use of npx instead.

npx cdk bootstrap
npx cdk deploy

2. Send messages via SQS Standard and FIFO queues

Two scripts have been written for you, send_messages_to_std_queue and send_messages_to_fifo_queue. As you might imagine, the command ./send_messages_to_std_queue would send messages to the SQS standard queue and the command ./send_messages_to_fifo_queue would send messages to the SQS FIFO queue.

Each execution sends 100 messages.

3. Run test to see if ordering is preserved.

A script has been written for you, confirm.py, that'll query all data from the DynamoDB table and check if ordering is preserved. To run the script, type in your terminal

python confirm.py
