Catch Dancing Ponies — Try Approval Testing
summary
Peguero Online is a cloud service that sends XML invoices through a REST API; tests upload real invoice files, convert returned PDFs to text and diff them against saved golden files so any unexpected change — even no dancing ponies — fails. The workflow uses regex filters to mask timestamps, runs with the open-source texttest (and optionally Falco’s ApprovalTests), complements existing Groovy/JBehave/Selenium suites, and serves as characterization tests during a large monolith-to-microservices refactor, catching many real regressions.
