From Manual API Testing to AI-Powered Automation with Keploy

“The best tests are the ones you didn’t have to write.”
This quote never hit harder until I explored Keploy for AI-powered API testing during the API Fellowship.

🧩 The Challenge

As a backend developer, writing Postman test cases, managing collections, and manually validating every edge case quickly becomes a chore — especially when you scale.

I had:

  • A working backend project (Node.js + Express)
  • A Postman collection for API testing
  • A basic CI/CD setup

But test coverage was limited. Writing and maintaining API tests manually felt repetitive and error-prone.

🤖 Enter Keploy: AI for API Testing

With Keploy, I:

  • Generated tests automatically from my OpenAPI schema and cURL/Postman collection
  • Used their Chrome Extension to capture live API interactions from websites
  • Achieved nearly 100% test coverage in minutes

No more writing test cases from scratch. Just feed the system with endpoints, sample inputs, and it does the heavy lifting.

🧪 Integrating Keploy in CI/CD

This was the fun part. I:

  • Used GitHub Actions to add Keploy testing in my pipeline
  • Pulled the CLI test command from the Keploy dashboard
  • Added my Keploy App ID and API key securely via GitHub Secrets
  • 🎉 My workflow now runs automated API tests on every push!

📊 Result? Crystal-clear reports

Keploy generated test reports showing:

  • Accepted/Rejected test cases
  • Suite coverage
  • Replay results

Everything surfaced in the dashboard — and I embedded a screenshot of the report in my repo’s README, as required.

🔍 Manual vs. Keploy Testing

Feature Manual Testing Keploy AI Testing
Time Required High Low
Test Case Writing Manual Auto-generated
Maintenance Effort Frequent updates needed Self-healing (AI-generated)
Accuracy Prone to human error More consistent & reliable
CI/CD Integration Needs scripting Seamless with GitHub Actions
Test Coverage Limited Can reach 90-100% quickly

💬 Final Thoughts

AI-powered API testing feels like the future. Keploy’s platform makes test generation, CI/CD integration, and execution smoother than ever. I’m excited to explore self-healing tests and test case sharing next.

If you’re tired of maintaining brittle API test suites — give Keploy a shot. It’s the AI wingman your CI/CD pipeline deserves. 🚀
