Testing

Local Testing (LocalStack)

After local deployment, get your API Gateway ID from Terraform output, or manually retrieve it:

cd terraform && terraform output api_gateway_id

Test LocalStack endpoints:

# Create short URL (replace <api-id> with your actual ID)
curl -X POST http://localhost:4566/restapis/<api-id>/local/_user_request_/urls \
  -H "Content-Type: application/json" \
  -d '{"url": "https://google.com"}'

# Test redirect (use returned code)
curl -L http://localhost:4566/restapis/<api-id>/local/_user_request_/urls/<code>

# Or directly visit
http://localhost:4566/restapis/<api-id>/local/_user_request_/urls/<code>

AWS Testing

After AWS deployment, get your API Gateway ID from Terraform output, or manually retrieve it:

cd terraform && terraform output api_gateway_id

Test AWS endpoints:

# Create short URL (replace <api-id> with your actual ID)
curl -X POST https://<api-id>.execute-api.us-west-2.amazonaws.com/dev/urls \
  -H "Content-Type: application/json" \
  -d '{"url": "https://google.com"}'

# Test redirect (use returned code)
curl -L https://<api-id>.execute-api.us-west-2.amazonaws.com/dev/urls/<code>

# Or directly visit
https://<api-id>.execute-api.us-west-2.amazonaws.com/dev/urls/<code>

Design

Functional Requirement

1. Users can post a long url and get a short url.
2. Visiting the short url should redirect user to the long url.
3. The short url is unique for every long url provided.
4. (Optional) Users can set a expiration date for the link.
5. (Optional) Users can use custom alias instead if it does not already exist.

Non-functional Requirement

1. User should receive the short url in 10 seconds.
2. The short url should be avaialble in 1 minute.
3. The service should support 30,000 DAU activities.
