AI-Powered API Testing in Minutes using Keploy Chrome Extension 🚀

As a developer, testing APIs manually can feel repetitive and time-consuming. Recently, I explored a smarter, faster way to test APIs using the Keploy Chrome Extension — and it completely changed how I look at testing!

🔍 What is Keploy?

Keploy is an open-source testing platform that uses AI to generate test cases for APIs just by observing network traffic. It eliminates the need to write tests manually — which is huge!

🧪 What I Tested

I tried out the Keploy Chrome extension on two dynamic websites that load data via API calls:

1. FakeStoreAPI
   
   A mock e-commerce API with product listings and user data.

2. JSONPlaceholder
   
   A classic test API that simulates posts, comments, users, etc.

I browsed each site, opened the Chrome DevTools, and enabled the Keploy extension. As I interacted with the websites, the extension automatically captured the API calls — including headers, payloads, and endpoints.

⚙️ How it Works

Once recording is enabled:

• The extension captures HTTP requests/responses.
• You can filter and view the API logs in real-time.
• You can export the test suite or replay the captured flows.

No need to write Postman collections or curl commands manually. Just click, interact, and Keploy does the rest.

💡 Key Takeaways

• Speed: I generated working API test cases in less than 5 minutes.
• Accuracy: It captured full request/response context — perfect for debugging.
• Ease: Zero config. Just open the extension and browse.

🤖 Why It’s Game-Changing

Before this, I had to:

• Manually write test cases
• Use Postman or Swagger for collections
• Set up test data repeatedly

Now, Keploy simplifies this with AI-generated test cases that I can run in CI/CD pipelines, saving me both time and effort.

⚙️ Next Step: Automate in CI/CD

The Chrome Extension works great for recording, but it gets even better when integrated into GitHub Actions using the Keploy CLI. That’s next on my checklist!

✅ Final Thoughts

If you're building or testing APIs, I highly recommend trying the Keploy Chrome Extension. It's beginner-friendly, super efficient, and helps you reach 100% test coverage with minimal effort.
