Meet Keploy—a game-changing open-source testing toolkit that’s now available on the VSCode Marketplace.
In this post, we’ll explore what Keploy brings to VSCode, how it streamlines testing, and why you should give it a spin today.
What is Keploy?
Keploy is an AI-powered testing tool that auto-generates test cases and mocks from real API traffic. It's designed for developers, testers, and DevOps teams who want to eliminate the manual pain of writing and maintaining tests.
Instead of writing tests line-by-line, Keploy records your application's API calls during development or staging runs and uses this data to auto-generate:
- Functional test cases
- Mock configurations for third-party dependencies
- Deterministic, replayable test runs
The result? Faster, more reliable CI pipelines and higher confidence in your deployments.
Keploy on VSCode Marketplace
The Keploy extension is now available on the VSCode Marketplace, enabling you to integrate it directly within your development environment.
Features of the VSCode Keploy Extension:
- Run Keploy Tests Locally: Execute your auto-generated tests right from the VSCode interface.
- Test Result Viewer: Get a visual representation of test success/failure and view logs in one click.
- Mock Management: Easily update, inspect, or reset mocks with a graphical UI.
- Traffic Capture Mode: Initiate traffic recording with just a toggle—no terminal hassle.
If you already use Keploy in your backend services, this extension brings those capabilities closer to your everyday development flow.
Why Use Keploy with VSCode?
- Zero Test Writing Overhead
Keploy captures API interactions in real-time and turns them into reusable test cases. This means fewer boilerplate test scripts and more time solving real problems.
- Seamless Developer Experience
VSCode’s sleek UI combined with Keploy’s auto-testing creates an intuitive, low-friction experience. The ability to toggle mocks, inspect test data, and rerun scenarios without switching tools is a huge win for productivity.
- Boost CI/CD Efficiency
Use Keploy’s tests in your CI pipeline to catch bugs early, ensuring every commit meets quality standards. The tests are deterministic, meaning they produce the same output each time—perfect for automated testing environments.
- Better Collaboration Across Teams
Keploy bridges the gap between developers, testers, and DevOps engineers by standardizing test data and mock behavior. This minimizes “works-on-my-machine” issues and increases team confidence in code changes.
