Why Testronaut

Mission-based, resilient, developer-friendly.

Plain-English missions

Define flows in natural language or lightweight JS functions. Fewer brittle selectors, more productivity.

Deterministic tool use

Guided actions via Playwright + structured DOM context. Less flakiness, clearer failures.

Mission Control reports

Upload run reports to visualize pass/fail, timing, and artifacts across suites.

From mission to execution

Write a mission, run it, review the report. That’s it.

  • • Write: Define a goal like “Log in and purchase an item”.
  • • Run: Testronaut controls a real browser with Playwright.
  • • Report: Upload to Mission Control for insights.
//Write:
// missions/login.mission.js
import { runMissions } from 'testronaut';

export const loginMission = 
  `Visit ${YOUR_SITE_HERE}.
  Fill the username field with ${USERNAME}. 
  Fill the password field with ${PASSWORD}.
  Click the Login button.
  Wait for the dashboard to appear.
  Take a screenshot
  Report SUCCESS if the dashboard is loaded, 
  otherwise report FAILURE.`;

export async function executeMission() {
  await runMissions({
    mission: loginMission
  }, "Login Mission");
}

// Run:
npx testronaut login.mission.js

//Report:
npx testronaut upload

FAQ

How is this different from Playwright/Cypress?

Testronaut uses LLM reasoning + structured DOM to perform steps from plain-English missions, then runs real browsers via Playwright. It aims to reduce brittle selectors and speed up authoring.

Is there a UI?

Yes — Mission Control lets you upload and visualize reports across runs, suites, and teams.

Is it open source?

The CLI is open source. Mission Control is a hosted companion for collaboration and analytics.

Where do I start?

Install the CLI with npm and join Discord for help. See the README for mission examples.
