A critical bug ships to production — you find out from a customer tweet
Your team says "it was tested" — but nobody can show you the tests
Testing is always the last thing cut when sprint scope tightens
You have no visibility into what's actually covered before release
✦ How Vellix Fixes It
Paste your requirements doc or user story → test cases generated instantly
Generate acceptance tests from plain English — no code knowledge needed
Create manual test cases for your QA team directly from feature specs
Proof of coverage: every feature has a test suite before it ships

Designers

🖼 UI Quality Guard
⚡ The Designer's Frustration
Your carefully designed UI breaks on tablet — nobody tested it
Accessibility requirements missed because devs didn't know to test them
Edge states (empty, error, loading) look broken in production
No way to validate interactions match the original Figma intent
✦ How Vellix Fixes It
Upload your Figma export or screenshot → UI test cases generated
Covers all UI states: empty, loading, error, success, disabled
Accessibility tests generated: contrast, keyboard nav, screen reader
Interaction flows tested: click, hover, focus, tab order
Every UI state covered before dev ships
Test your designs, not just code

Regulated, high-stakes, or fast-moving — every industry has bugs that hurt differently. Vellix generates tests that reflect your domain's actual risk profile.

💳

Fintech

Payments · Lending · Banking
⚡ The Fintech Risk
A payment gateway bug processes ₹0 instead of ₹10,000 — twice
Regulatory audit finds untested edge cases in your transaction logic

Protect your financial calculations
🛡️

Insuretech

Claims · Underwriting · Policy
⚡ The Insuretech Risk

☁️

SaaS Platforms

B2B · Multi-tenant · API-first
⚡ The SaaS Risk
Multi-tenant data leak: Org A can accidentally see Org B's data

API rate limiting not tested — one heavy client kills the whole platform
Third-party integration breaks on their API update — you find out from Slack
✦ How Vellix Fixes It
Tenant isolation tests: cross-org data access boundary validation
Billing webhook tests: success, failure, retry, duplicate handling
Rate limit tests: burst, throttle, quota reset behaviour

Crypto & Web3

Exchange · DeFi · Wallet
⚡ The Crypto Risk
Smart contract bug: funds locked forever, no rollback

🏥

Healthtech

EHR · Diagnostics · Telehealth
⚡ The Healthtech Risk
Patient record mismatch: wrong drug dosage displayed for wrong patient

Booking · OTA · Hotels
⚡ The T&H Risk
Double-booking during peak season — hotel has no room, guest is stranded
Price calculation wrong with promo code + loyalty points combination
Payment retry logic creates duplicate bookings after timeout
Cancellation policy calculation wrong — incorrect refund issued
✦ How Vellix Fixes It
Inventory lock tests: concurrent booking prevention under high load
Price calculation tests: all promo + loyalty + tax combinations
Idempotency tests: payment retry creates no duplicate bookings
Cancellation tests: all policy types, dates, partial refund scenarios
Peak season bugs cost more than a year of testing

By Test Type

Every test type.
One platform.

Unit, API, UI, performance, security, AI prompt testing — Vellix generates them all from the same input. No switching tools. No framework gymnastics.

🎯

API Testing

REST · GraphQL · gRPC
⚡ The API Testing Gap
You test the happy path — 404, 422, 500 are untested in CI
OpenAPI spec changes break consumers — nobody has contract tests
Auth header missing returns 200 instead of 401 — security hole
✦ Vellix API Test Output
All HTTP status codes: 200, 201, 400, 401, 403, 404, 409, 422, 429, 500
Request validation: missing fields, wrong types, oversized payloads
Auth tests: no token, expired token, wrong scope, valid token
Response schema validation against your OpenAPI spec
Paste your API spec → complete test suite in 3 seconds
Generate API tests now

Web / UI Testing

Playwright · Cypress · Selenium
⚡ The UI Testing Gap
UI tests are brittle — selector changes break 30 tests at once
Empty states, error states, loading states never tested
Cross-browser bugs found by users, not your test suite
✦ Vellix UI Test Output
Upload screenshot → Playwright/Cypress tests for every visible element
All UI states: loading, empty, error, success, partial data
Interaction tests: click, type, hover, focus, blur, scroll
Resilient selectors: ARIA roles and test IDs, not brittle CSS paths
Screenshot → test in under 60 seconds
Generate UI tests from screenshots
📱

Mobile App Testing

Appium · XCTest · Espresso
⚡ The Mobile Testing Gap
App works on Android 14 but crashes on Android 11 — 40% of your users
Offline mode untested — app breaks when network drops
Interrupt scenarios (calls, notifications) crash the app mid-flow
✦ Vellix Mobile Test Output
Appium tests from your UI screenshots or feature descriptions
Interrupt tests: incoming call, low battery, network switch
Offline/online transition tests: data sync, error recovery
Gesture tests: swipe, pinch, long-press, shake
Android + iOS tests from one generation
Generate mobile tests

Performance Testing

Load · Stress · Spike
⚡ The Performance Gap
API works fine for 10 users, collapses at 1000 — found on launch day
Database queries not indexed — slow for small data, dead for large
Memory leak in long-running process crashes the server after 6 hours
✦ Vellix Performance Test Output
Load test scenarios: ramp-up, steady state, peak, and drain
Threshold assertions: p95 response time, error rate, throughput
Database query tests: response time under N records
Concurrent user tests for your specific endpoints
Know your limits before users find them
Generate performance tests
🔒

Security Testing

OWASP · Auth · Injection
⚡ The Security Gap
SQL injection found by a pentester — 6 months after launch
JWT validation skipped in one endpoint — entire auth bypassed
CORS misconfigured — any origin can read your API responses
✦ Vellix Security Test Output
OWASP Top 10 tests generated from your API spec or code
Injection tests: SQL, NoSQL, command, LDAP, XSS
Auth bypass tests: token tampering, privilege escalation, IDOR
Header security tests: CORS, CSP, HSTS, clickjacking
OWASP Top 10 covered before your first pentest
Generate security tests
🤖

AI Prompt Testing

LLM · RAG · AI Features
⚡ The AI Testing Gap
Your AI feature hallucinates on edge-case inputs — no test caught it
Prompt injection attack makes your chatbot reveal system prompts
AI response quality degrades after model update — nobody noticed
✦ Vellix AI Test Output
Prompt injection tests: attempts to override or extract system prompts
Output quality tests: structure validation, length bounds, tone
Edge input tests: empty, adversarial, multilingual, jailbreak attempts
RAG tests: retrieved context relevance, hallucination boundary cases
AI features need tests too — not just vibes
