Practice real-world API testing with realistic mock e-commerce datasets, JWT Bearer authentication, chaos status code simulation (200 to 503), and network delay injections for Bruno, Postman, Playwright, Cypress, and RestAssured.
All the realistic e-commerce endpoints, edge-case chaos, and auth workflows you need to write rock-solid test suites.
Create, update, and delete mock products and users freely. Never worry about corrupting shared test environments or leaking real database credentials. Reset back to clean defaults anytime.
Simulate edge-case HTTP status codes on demand: 400 Bad Request, 401 Unauthorized, 404 Not Found, 429 Rate Limit, and 500 Server Error without crashing real backends.
Simulate slow mobile networks or slow database queries by injecting 0ms to 5000ms delay. Essential for verifying timeout thresholds, loading skeletons, and retry logic.
Practice end-to-end authentication flows. Log in to capture a Bearer token, automatically attach it into automation test runners, and execute protected CRUD calls.
Generic mock tools were built for frontend UI wireframes. QAFakeAPI is purpose-built with real stateful mutations, chaos error simulations, and Bruno collection integration for professional API testing.
| Feature / Capability | QAFakeAPIFOR QA | Generic Mock APIs | Basic Echo Tools | Demo Store Mocks |
|---|---|---|---|---|
Primary Target Audience Optimized specifically for QA workflows, SDET automation & Bruno tutorials | 🎯 QA Engineers & SDETs | Frontend UI prototyping | Basic HTTP dummy echo | E-commerce mock data |
Real In-Memory DB Mutations POST, PUT, PATCH, and DELETE actually mutate the database state in real-time | ✅ Real Stateful Changes | ❌ Fake 200 (No state change) | ❌ Fake 201 (Stateless echo) | ❌ Fake 200 (No state change) |
Instant 1-Click Database Reset Reset all mock products, users, and orders back to initial defaults anytime | ✅ Yes (Button & /api/v1/reset) | ❌ Not available | ❌ Not available | ❌ Not available |
JWT Bearer Authentication Flow Authenticates credentials, issues real JWT tokens, and protects endpoints | ✅ Real Bearer Chaining | ❌ No auth support | ⚠️ Static fake token only | ⚠️ Basic token (unverified) |
Chaos & Negative Testing (400 - 503) Simulate 400 Bad Request, 401 Unauthorized, 429 Rate Limit, 500 & 503 Server Errors | ✅ Built-in /mock/status/:code | ❌ 200 OK only | ⚠️ Limited 400 only | ❌ 200 OK only |
Network Latency & Delay Injections Inject 0 to 5000ms delay to test request timeouts and loading indicators | ✅ Custom /mock/delay/:ms | ❌ No delay support | ⚠️ Fixed query param only | ⚠️ Fixed query param only |

While our basic Bruno starter collection is completely free to download in the Studio Playground, this professional toolkit delivers 5 production-ready automation frameworks (Playwright, Cypress, Python, Java, Bruno Masterclass) with CI/CD workflows, token chaining, and the complete 50 SDET interview answer bank.
The exact workflow used by professional QA engineers to test and automate production APIs.
Press F12 in your browser and switch to the Network tab.
Open the Studio Playground or any web app to trigger network requests.
Right-click the network entry in DevTools → Copy → Copy as cURL.
In Bruno, click Import → Paste raw text / cURL. Run, add assertions, and automate!
