Senior API Automation Expert
Parveen is a senior API automation expert at Total Shift Left. She designs schema-aware test generation strategies, contract-testing workflows, and CI/CD integrations for enterprise QA teams. She writes about practical, day-to-day API testing topics — coverage gaps, regression patterns, test data management, and how to operationalise AI-generated tests inside a real engineering pipeline.
A practical template for writing API test cases, with worked examples across positive, negative, boundary, and security scenarios — and how each one maps directly onto an automated test.
A k6 quick-start for API load testing: virtual users, check() and thresholds, staged ramp-up, POST requests, and running k6 in CI/CD with a non-zero exit code on threshold breach — with working scripts.
How to test GraphQL APIs — the real differences from REST testing, working code in the frameworks you already use, and the tools built specifically for GraphQL exploration and testing.
A hands-on tutorial for testing REST APIs with Python: pytest fixtures, the requests library, JSON schema validation, parametrized tests, and a GitHub Actions CI pipeline — with working code for every example.
Apidog and Postman both handle API design, testing, and documentation, but their architectural models differ fundamentally. Apidog treats the OpenAPI spec as the single source of truth, while Postman converts specs into independent collections. This focused comparison covers the differences that matter for team productivity.
AI API automation outperforms traditional API testing on coverage, maintenance, and triage time — but the trade-offs are nuanced. Here is a 2026 side-by-side analysis with TCO, coverage trajectories, and decision rules.
Codeless tools removed the requirement to write code. AI tools removed the requirement to author tests at all. Here is the 2026 buyer's guide to choosing between them — features, scalability, cost, and the right fit.
AI regression testing detects API drift, breaking changes, and silent contract violations on every commit — without anyone hand-writing regression tests. Here is the playbook for adopting it in 2026.
Every difference between OpenAPI 3.0 and 3.1 — JSON Schema 2020-12 compatibility, nullable handling, webhooks, exclusiveMinimum/Maximum — with before/after YAML for each change and a step-by-step migration checklist.
