Your tests check logic.
Tessera checks reality.

AI-powered acceptance testing for iOS. Verifies what your users actually see against what your API actually sends.

What Tessera covers

Does the screen show the right data?
What happens with edge case data?
Does the API response match the UI?
Did this PR introduce a regression?

Three commands. Full coverage.

01

Discover

$ tessera explore

AI navigates your app screen by screen, discovers every feature, and generates expectations automatically.

02

Test

$ tessera test

Evaluates every screen against expectations and your API data. Catches mismatches, regressions, and edge cases.

03

Fix

$ tessera fix

Analyzes failures, searches your codebase, and suggests the exact code fix with a diff you can apply.


See it in action

Tessera reviews every PR — catches data mismatches, suggests fixes, blocks the merge.


What Tessera actually catches

Real evaluation output for an Order History screen

// API response: GET /api/orders returned 3 orders
3 orders displayed (matches API count of 3)
Order #1001 shows 'Delivered' badge with green color
Order #1002 shows 'Processing' but API says 'cancelled'
→ UI BUG: status mapping incorrect for cancelled orders
Orders sorted by date descending
In-transit order shows tracking link

No visual testing tool catches this — because they don't know what the data should look like.


Not pixel diffing. Genuine AI understanding.

📊

Data-Aware

Tests what's on screen against what your API returned. Catches status mismatches, missing items, wrong counts.

👁

Vision-First

AI sees your app the way a user does. No accessibility IDs, no test scripts, no brittle selectors.

🔄

Self-Improving

Learns from regressions and auto-generates new expectations. The more you use it, the more it catches.

🚠

CI-Native

GitHub PR comments with results, status checks that block merges, dashboard to track quality over time.
