AI-powered testing platform. Write tests in plain English, run them everywhere.
AI Testing
AI testing uses machine learning to make software testing faster, more reliable, and less dependent on manual effort. In 2026, AI can generate test cases from a URL, automatically heal broken tests after UI changes, detect visual regressions, and prioritize which tests to run based on risk. This guide explains
Test Automation
Selenium is the original web automation framework, powering browser tests since 2004. This tutorial covers everything from installation to running your first test — in Python and JavaScript. You'll also learn Selenium's biggest pain points (explicit waits, element staleness, cross-browser setup) and when modern tools like Playwright
Test Automation
Cucumber is a BDD (Behavior-Driven Development) testing tool that lets you write tests in plain English using a format called Gherkin. Business stakeholders write scenarios like "Given I'm logged in, When I add an item to the cart, Then the cart shows 1 item" — and developers
Test Automation
Node.js has excellent testing support in 2026. The built-in node:test module handles most use cases without extra dependencies. For richer tooling, Jest and Vitest are the top choices. This guide covers everything: picking the right tool, writing unit and integration tests, mocking modules, testing async code, and setting
Test Automation
Cypress is a JavaScript E2E testing framework built specifically for the modern web. It runs inside the browser, giving you real-time visibility into your tests as they execute. This guide covers installation, writing your first tests, handling authentication, CI integration, and when to choose Cypress over Playwright or Selenium. Key
Agencies
Your client's checkout flow broke on a Tuesday. By Friday, when they noticed the revenue drop and called you, four days of orders had failed silently. Manual QA doesn't scale across a portfolio — and at 20+ client sites, it's not a process problem, it&
Agencies
Your client found out their contact form was broken when a competitor poached their lead. You found out when the client called you. Now multiply that by twenty client sites, and you understand why agencies lose accounts over things they never knew were broken. Testing multiple websites doesn't
Tools & Frameworks
Jest is the most widely used JavaScript testing framework. It ships with everything you need: a test runner, assertion library, mocking system, and code coverage. This guide covers setup, writing tests, mocking dependencies, testing async code, React Testing Library integration, and common patterns. Key Takeaways Jest is batteries-included. Unlike Mocha
Testing Strategy
Most startup founders skip testing because it feels like it slows them down. Then they spend entire weekends debugging production issues that a 10-minute test would have caught. This guide gives you a minimal, practical testing strategy that protects your core flows without requiring a QA team or dedicated test
Agencies
Your client's contact form has been broken for three weeks. They found out when a prospect told them. You lost the account. This is the scenario agencies dread — and it's entirely preventable with automated website testing. One setup, continuous monitoring, zero manual clicking. Key Takeaways Manual
Testing Strategy
Your app works fine with 10 users. You launch a Product Hunt campaign, 500 people hit it simultaneously, and it falls over. Load testing finds that breaking point before your users do. This guide covers what load testing is, which tools to use, what metrics matter, and how to run
Testing Strategy
Cross-browser testing validates that your application works correctly across different browsers and versions. It matters because Chrome's behavior isn't Safari's behavior — CSS rendering, JavaScript APIs, and font handling differ in ways that break real users' experiences. The good news: modern tools make it
