How to Automate PDF Validation in Playwright and Cucumber BDD

A technical guide outlines a structured approach to validating generated PDFs within automated end-to-end testing frameworks. The workflow uses Playwright to trigger and capture PDF downloads, storing files locally before parsing their content. Tools like pdf-parse and ajv enable text extraction, regex-based field capture, and JSON Schema validation. Cucumber BDD step definitions tie the process together, allowing testers to assert static text, dynamic data paths, and document structure in readable feature files. Best practices recommended include using stable test selectors, storing test data in JSON files, and cleaning up downloaded PDFs after test runs.
