API Test Generator

🤖 Why AI for API Testing?

API Testing Challenge	ROI & Impact
Edge-case, bugs, coverage flows gets missed	Higher test coverage across CRUD and failure scenarios
APIs change frequently, leading to broken tests	Self-healing keeps tests even when APIs evolves
30–50% of time spent writing tests	50–80% reduction in test creation Covers more edge cases within limited resources, time

💥 Why Keploy? Not Other AI Testing Tools

Capability	Keploy	Most AI Tools
Validated test execution	✅ Runs and verifies each test before saving	❌ Often generates unverified or broken tests
Full API flow coverage (Create → Update → Delete)	✅ Supports complete multi-step flows	❌ Focuses on isolated requests
Edge case & negative test generation	✅ Auto-detects and generates edge cases	⚠️ Limited or requires manual prompting
Replay across environments	✅ Runs tests in dev, staging, CI with environment switching	⚠️ Often environment-specific or hard-coded
Self-healing on API changes	✅ Updates tests if API schema changes	❌ No maintenance support
Flaky test detection	✅ Re-runs tests to detect instability	❌ Not supported
Collaboration & governance features	✅ RBAC, audit trails, tagging, Git sync	❌ Basic or missing
Works from real traffic or browser flows	✅ Converts real traffic or frontend API interactions into tests	⚠️ Most rely only on static specs

🚀 Keploy's API Test Generator

AI-powered testing engine that turns your API specs or traffic into stable, end-to-end test suites — no scripts, mocks, or manual setup required.

It supports:

• Generate tests from OpenAPI, Postman, or curl commands
• Run tests in any environment (dev, staging, CI)
• Edit, group, or delete test cases in the UI
• Share test reports or integrate them into CI pipelines
• Detect flaky tests and self-heal them using AI
• Record API flows via Keploy’s Chrome extension

Every test includes:

• Accurate assertions based on real responses
• Full lifecycle coverage (create → mutate → delete)
• Deduplication and flaky test detection
• Self-healing for minor API changes

Whether you're a developer, SDET, or QA manager — Keploy helps you increase test coverage, reduce test debt, and ensure reliable releases across environments.

🛠️ How It Works

Keploy supports multiple ways to generate test cases depending on the API access method and input format. Choose the one that fits your workflow:

Integration Method	When to Use	How Keploy Works?
Paste API Curls, Postman Collection, Schema/Swagger Try Now	You have OpenAPI/Swagger (YAML/JSON), Postman collection/curl, and a live public endpoint	Keploy hits multiple API cases to given endpoint and generate stable, validated tests with assertions.
Record via Keploy Chrome Extension	You don’t have specs but can interact with a web app for recording	Keploy captures real API calls made during UI actions and generates test cases with assertions. Adds edge cases and flow coverage automatically.
Use Keploy Local Agent Try Now	Your APIs are private or behind a firewall	Install the agent locally to securely test internal APIs without exposing them. No code changes required.

✨ Key Features

• Self-healing tests: Keploy auto-updates tests on minor API changes
• Flaky test detection: Validates each test over multiple runs
• No redundant tests: Automatically deduplicates similar flows
• Environment reuse: Change the base URL to run the same test suite elsewhere
• One-click fix: Use AI to repair failing tests

✅ Best Practices

• Start with 5+ valid curl commands or a full spec
• Use the dashboard to clean, tag, or group test cases
• Validate flows in staging before pushing to CI
• Use assertions to cover both happy paths and edge cases
