Testing at a new level of robustness

01.

Meticulous monitors your daily interactions with your application as you develop it

Add a script tag to your local development, staging, and preview URL environments to record sessions. Optional: record production sessions too for additional coverage.

02.

Our AI engine generates a continuously evolving test suite that covers every corner of your application

By tracking the code branches executed by each interaction Meticulous curates a suite of visual end-to-end tests that cover of every line of your codebase. Every user flow. Every edge-case.

By default Meticulous mocks out the responses from your backend by saving and replaying the original recorded responses - this means side-effect free tests with no false positives from changing data, and no need to set up special test accounts or mock test data for each test run. Just add the recorder script, click to install the integration for your CI and you're good to go.

Never write, fix or maintain a test again: your tests automatically evolve as your app evolves.

Iterate at velocity

Dramatically increase the speed you can ship reliable regression-free code. Meticulous continually adds new tests as new features or edge cases are introduced, and removes old tests as they become out of date - ensuring your test suite is always up to date and complete, without any intervention required by developers.

Built to eliminate all flakes, from the ground up

Built from the Chromium level up with a deterministic scheduling engine – making it the only testing tool that eliminates flakes. This technology also allows Meticulous to execute tests at lightning fast speeds. Battle-tested to work with even the most complex applications.

"We trust Meticulous to be the sole front-end testing system for our app. It has caught countless UI bugs and regressions without us having to write a single test. This coverage saves us time and gives us confidence to move quickly."

Nick Hrynuik

Engineer at WithPower

"Within the first two weeks of using Meticulous, our team prevented over five regressions, significantly boosting our engineers' confidence in the codebase quality. The ability to introduce changes without fear of breaking existing functionality has been invaluable."

Gerald Sornsen

Engineering Manager at Lattice

Use in combination with your existing test suite, or as a replacement

You can use Meticulous to complement any existing tests you have, or replace your existing tests entirely.

Lightning fast testing – at scale

Tests are heavily parallelized across a compute cluster, allowing you to test 1000s of screens and get results in under 120 seconds.

get started by adding the meticulous recorder script tag

Add to your _document.js <Head> or /app/layout.tsx <head> tag:

{process.env.NODE_ENV === "development" && (
  <script data-project-id="..." src="https://snippet.meticulous.ai/v1/meticulous.js"></script>
)}

import { tryLoadAndStartRecorder } from '@alwaysmeticulous/recorder-loader'

async function startApp() {
  // Record all sessions on localhost, staging stacks and preview URLs
  if (!isProduction()) {
    await tryLoadAndStartRecorder({    
      projectId: '...',
      isProduction: false,
    });
  }
  
  ReactDOM.render(component, document.getElementById('root'));
}

function isProduction() {
  return window.location.hostname.indexOf("your-production-site.com") > -1;
}

startApp();

import Vue from "vue";
import App from "./App.vue";
import router from "./router";
import store from "./store";
import { tryLoadAndStartRecorder } from '@alwaysmeticulous/recorder-loader';

async function startApp() {
  if (!isProduction()) {
    await tryLoadAndStartRecorder({    
      projectId: '...',
      isProduction: false,
    });
  }
  
  new Vue({ router, store, render: h => h(App)}).$mount("#app");
}

function isProduction() {
 return window.location.hostname.indexOf("your-production-site.com") > -1;
}

startApp();

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
    import { AppModule } from './app/app.module';
    import { tryLoadAndStartRecorder } from '@alwaysmeticulous/recorder-loader'
    async function startApp() {
        if (!isProduction()) {
          await tryLoadAndStartRecorder({    
            projectId: '...',
            isProduction: false,
          });
        } 
        
        // Initalise app after the Meticulous recorder is ready, for example:
        platformBrowserDynamic().bootstrapModule(AppModule)
         .catch(err => console.error(err));
    }
    
    function isProduction() {
        return window.location.hostname.indexOf("your-production-site.com") > -1;
    }
    
    startApp();

{
 head: {
  script: process.env.NODE_ENV === "production" ? [] : [
   {
    src: 'https://snippet.meticulous.ai/v1/meticulous.js',
     ["data-project-id"]: '...',
     ["data-is-production-environment"] false,
    }
   ],
  }
}

   data-is-production-environment="false"
