🧪 FusionTest

AI-powered UI testing for mobile and desktop — built by FusionLeap.io

FusionTest uses large language models to execute UI tests the way a human would — reading screens, making decisions, and adapting to UI changes automatically. No brittle scripts. No maintenance overhead. Just natural language test goals that run anywhere.

🚀 Quickstart

Prerequisites

Python 3.10+
Node.js 18+ (for Playwright/Electron targets)
Appium 2.x (for mobile)

Install

git clone https://github.com/mohigo/fusion-test.git
cd fusion-test
pip install -e ".[dev]"

Set your API key

export FUSIONTEST_API_KEY=your_key_here
# or copy .env.example → .env and fill in values

Run your first test

fusiontest run --goal "Log in, navigate to settings, update profile name" \
               --platform android \
               --app path/to/app.apk \
               --locale en-US

Full guide: docs/getting-started.md — covers all platforms (web, Android, iOS, Electron, Windows, macOS), Python API usage, configuration, dashboard, CI setup, and tips for writing good goals.

📝 Writing Test Goals

FusionTest accepts natural language goals. No code required.

# tests/goals/onboarding.yaml
name: User onboarding flow
platform: android
locale: en-US
goals:
  - "Open the app and tap Get Started"
  - "Enter email address and password on the signup screen"
  - "Verify the home dashboard loads with a welcome message"

Run it:

fusiontest run --file tests/goals/onboarding.yaml

🔌 CI/CD Integration

GitHub Actions

- name: Run FusionTest
  uses: fusionleap/fusiontest-action@v1
  with:
    goal-file: tests/goals/smoke.yaml
    platform: android
    api-key: ${{ secrets.FUSIONTEST_API_KEY }}

Bitrise / Fastlane

See docs/ci-integrations.md for step-by-step guides.

📊 Reporting

Every test run produces:

Pass/fail summary with stability score
Screen-by-screen action log
Video recording of the test session
Bug report with screenshot + repro steps (on failure)

Results are posted to your FusionTest dashboard and optionally to Slack.

🛠 Configuration

# fusiontest.config.yaml
model:
  backbone: mpnet-base          # or: gpt-4o, claude-sonnet (for MVP/fallback)
  precision_threshold: 0.97
  max_retries: 3

guardrails:
  loop_detection: true
  loop_window: 5                # check last N screen states
  backtrack_on_invalid: true
  max_backtracks: 2

devices:
  android:
    farm: browserstack           # or: aws-device-farm, local
  desktop:
    vision_fallback: true        # enable for non-accessible UIs
    playwright_for_electron: true

reporting:
  slack_webhook: ${SLACK_WEBHOOK}
  save_recordings: true
