The Gap
Individual endpoint tests all passed, but integration bugs kept appearing in production. Login worked. Checkout worked. But login → browse → checkout broke because session tokens weren't properly validated between endpoints. Traditional testing focuses on isolated endpoints because that's easier to automate — but production bugs happen at the boundaries where endpoints interact.
What's New
Keploy introduces full API flow testing. Keploy now automatically maps and tests complete user journeys instead of isolated calls.
Full API Flow Capabilities
Keploy brings real-world API flow coverage — validating how endpoints interact end-to-end:
Automatic Flow Detection
Analyzes API traffic to identify logical sequences like /login → /profile → /checkout, building test flows that mirror actual user behavior.
Multi-Endpoint Test Chains
Automatically chains calls — login → extract token → reuse in profile → checkout with session continuity — validating cross-endpoint integrity.
Data Flow Validation
Ensures critical data flows correctly: checkout triggers inventory update, orders link back to user accounts, and responses remain consistent across calls.
Real-World Usage Patterns
Tests are generated from real traffic and user behavior, not theoretical specs — meaning every flow reflects how your APIs actually get used in production.
Endpoint Testing vs. Flow Testing
E-Commerce API Example:
Before
Individual Endpoint Tests
- ✓
POST /auth/login200 OK - ✓
GET /products200 OK - ✓
POST /cart/add201 Created - ✓
POST /checkout201 Created
Problem: Don't know if they work together.
After
Flow-Based Tests
- Guest Checkout FlowProducts → Add to cart → Checkout → Verify inventory updated
- Authenticated PurchaseLogin → Profile → Cart → Checkout → Verify loyalty points applied
- Multi-Item CartAdd 3 items → Checkout → Verify single order with all items
Catches: Token validation failures, cart not clearing, missing loyalty points.
Real Scenario
Before: You refactor /checkout. Individual tests pass. Ship to production. Users report carts not clearing and loyalty points not applied — bugs that only appear in full flow testing.
With Keploy: The same refactor triggers flow test failures:
- "Authenticated Purchase" flow: Cart not cleared ❌
- "Loyalty Points" flow: Points not calculated ❌
You catch and fix integration bugs before shipping.
Why This Matters
Most production API bugs don't come from failing endpoints — they come from endpoints that fail to work together. Flow-based testing validates how your API behaves in real user sequences, catching integration issues that endpoint testing misses.
Keploy introduced one-click generation and AI-organized test flows — making test creation faster and the interface cleaner than ever.
