Simulating and Testing Third Party Service Integrations
summary
A small Ruby library called request interceptor simulates HTTP services using a concise Sinatra app per service, runs as a Rack middleware in development, and records transactions for assertions via an RSpec matcher. It supports every HTTP client that web mock supports (work was done to integrate with web mock), can raise simulated infrastructure errors, and generates factory-backed JSON responses. It scales to large codebases (Shopify example: ~800 engineers) and fits into a 25 minute demo.
