HOW IT WORKS

Zero setup.
Zero learning curve.

Describe what to test

Your AI explores your app like a manual QA tester — clicking through pages, filling forms, spotting edge cases. You describe the intent. It does the work.

❯ test my login flow ● test url: localhost:3000 ⎿ Exploring pages · forms · user flows

Intent gets recorded, not selectors

Every interaction is saved as an intent-based test — "click the login button", not click('#btn-a3f'). Like a QA engineer's notes, but executable and replayable.

● save_suite "Login Flow" ⎿ Saved · 4 test cases ✓ login flow 4/4 passed ✓ ... 11 more passed

AI changes code. You re-run.

Your AI refactors something. Say "test my feature" again. FastTest compares against the baseline and tells you exactly what broke, what got fixed, and what's new.

❯ run my tests ● run "Login Flow" ✗ login flow — regression ✓ cart validation — fixed 13/14 passed · 1 regression

Broken selectors heal themselves

When your AI renames a button, 4 repair strategies kick in automatically. Real bugs get flagged. Cosmetic changes get healed. Every fix is stored org-wide.

● heal button#login ② data-testid="login-btn" ✓ 0.98 ⎿ Healed — selector change, not a bug ✗ session persists — real bug
SELF-HEALING ENGINE

Tests that
maintain
themselves.

Your AI refactors the DOM. Renames buttons. Restructures forms. Normal tests shatter. FastTest fires a 4-strategy healing cascade that separates real bugs from cosmetic changes. Every fix is stored org-wide — the same rename is healed instantly for every teammate, on every future run.

Pattern DB (instant reuse)40%
data-testid / ARIA28%
Text content match19%
Structural (DOM)13%

The compounding effect: After one month, most selector failures are resolved via the pattern DB in <50ms — no DOM scanning, no AI calls, no cost. Every heal makes every future run faster.

// Deploy pushed at 14:32 UTC // Designer renamed the button await page.click('#submit-btn-old') // ✗ ElementNotFoundError // No element matches: #submit-btn-old // Test suite: FAILED (11/12)
WHAT YOU GET

Easy to start.
Hard to break.

◆

Tests written for humans

Describe what to test in plain English. Your AI records intent-based steps anyone can read.

◎

Tests your AI can't delete

Tests live in the cloud, not your repo. Refactor everything — the safety net stays intact.

⚡

Self-healing selectors

Renamed a button? Four repair strategies fix it automatically. Real bugs get flagged, cosmetic changes get healed.

⚠

Regression detection

Every run is compared to the last. See exactly what broke, what got fixed, and what's new.

◇

Security testing built in

Say "secure my app" for SAST, SCA, and DAST in one command. Static code analysis + dependency scanning + browser adversarial testing. Findings become regression tests.

Watch it happen live

The War Room shows every test executing in real time — actions, logs, and healing events.

HOW FASTTEST IS DIFFERENT

Not another wrapper.
A different architecture.

FASTTEST
PLAYWRIGHT MCP
PLAYWRIGHT / CYPRESS
Write tests
✓Describe what to test in plain English
✓Natural language via host agent
–Write selectors, assertions, fixtures
Test readability
✓Intent-based steps — read what is tested, not how
–Generated Playwright code, intent lost in selectors
–Selector-heavy code, hard to review
Selector healing
✓5-strategy cascade, stored org-wide
–Raw selectors, no healing
–Fix every broken selector by hand
DAST security
✓Browser-driven OWASP Top 10 adversarial testing
–Not included
–Separate DAST tool needed
SAST + SCA
✓Static analysis + dependency scanning built-in
–Not included
–Separate tools needed
Extra LLM cost
✓Zero — your coding agent does all the reasoning
–Extra cloud LLM layer on top of host agent
✓No AI involved
Session persistence
✓Save/restore login across test runs
–No session persistence
~Manual storageState files
Saved test suites
✓Cloud-stored suites, re-run anytime
–No persistence between sessions
✓You manage test files in your repo
Faster re-runs
✓Cached selectors, healing patterns & sessions — re-runs are near-instant
–Starts from scratch every time
✓Deterministic scripts, consistent run time
