I will automate your API and backend testing using postman and newman
Over deze dienst
Every backend update carries the risk of a silent breaking change. I set up automated API test suites that catch issues before your customers do validating endpoints, response schemas, and edge cases every time your backend changes.
What I offer:
- Postman collection creation and organization
- Automated request chaining (auth tokens, dynamic variables)
- Response validation (status codes, schema, response time)
- Newman CLI integration for command-line and CI/CD runs
- Negative and edge-case test scenarios, not just happy paths
Who this is for:
SaaS companies and dev teams pushing frequent backend updates who need confidence that new deployments haven't broken existing endpoints without manually re-testing every API call.
Why work with me:
I build suites that plug into your existing CI/CD pipeline, so testing happens automatically on every deploy not just when someone remembers to run it

Veelgestelde vragen
Do you need API documentation to start?
Yes — Swagger/OpenAPI docs or an existing Postman collection speeds things up significantly.
Can this run automatically on every deploy?
Yes, via Newman + your CI/CD tool (included in Premium, available as an add-on otherwise).
Do you test authentication flows (OAuth, JWT)?
Yes, included in all packages.
What if my API has more than 25 endpoints?
Message me before ordering for a custom quote based on your total endpoint count.
Do I need to share production credentials?
No — staging or sandbox environment credentials are strongly preferred and sufficient.
What's the difference between the packages?
Basic covers core endpoint checks. Standard adds chained requests and CLI automation. Premium adds full CI/CD integration, scheduled runs, and edge-case coverage.
Can you test GraphQL APIs too?
This gig is built around REST APIs; message me first if you're using GraphQL so I can confirm scope.
Do you provide the test scripts, or just a report?
You get the full Postman collection and scripts — fully yours to keep, edit, and rerun.
What happens if a test fails during setup?
I'll flag it immediately with details — it's often a sign of an existing backend bug, not a scripting issue.
