Test automation tutorials, frameworks, and tools — from first scripts to full CI/CD pipelines.
AI Testing
Autonomous QA testing refers to AI systems that handle test creation, execution, maintenance, and failure analysis without continuous human involvement. In 2026, the category has matured from experimental to production-grade — with self-healing tests, AI-powered test generation, and agentic workflows now standard in modern QA platforms. This guide covers what'
AI Testing
Agentic testing means AI agents that autonomously handle steps in the testing cycle — creating tests, running them, analyzing failures, and fixing issues — without waiting for explicit human instruction at each step. This guide covers the patterns, tools, and implementation approach for teams adopting agentic testing workflows in 2026. Key Takeaways
Cross-Browser Testing
CSS looks different in different browsers. Safari lags on newer features. Firefox interprets certain specifications differently from Chrome. Internet Explorer is thankfully gone, but Edge, Safari, and Firefox all have their own quirks. This guide covers the most common cross-browser CSS issues, the tools that catch them, and the techniques
Cross-Browser Testing
Selenium Grid lets you run tests across multiple browsers and machines in parallel by routing test commands from a central hub to registered browser nodes. Grid 4, the current version, supports standalone mode, hub/node mode, and fully distributed mode. Docker Selenium makes spinning up a cross-browser grid trivial. This
Cross-Browser Testing
Safari is the hardest browser to automate. Its WebDriver implementation is more restrictive than Chrome or Firefox, it can only run on macOS and iOS hardware, Apple Silicon introduced new compatibility issues, and the WebKit engine has quirks that no other browser shares. This guide covers the specific challenges of
Cross-Browser Testing
Playwright is the most capable cross-browser testing framework available in 2026. It ships with bundled Chromium, Firefox, and WebKit engines, runs the same tests across all three without modification, and executes them in parallel by default. This guide covers everything from initial setup to CI configuration and handling browser-specific behavior.
Cross-Browser Testing
BrowserStack and LambdaTest are the two dominant cloud browser testing platforms. BrowserStack has the largest real-device lab, the most mature enterprise integrations, and the highest price tag. LambdaTest is faster for parallel execution, significantly cheaper, and has closed most of the feature gap in the last two years. This comparison
Cross-Browser Testing
Cross-browser testing verifies that your web application looks and behaves correctly across different browsers, operating systems, and devices. With Chrome, Safari, Firefox, and Edge each rendering pages differently, skipping cross-browser testing means real users hit bugs you never saw. This guide covers what to test, which browsers matter, and how
Test Automation
Unleash is an open-source feature flag management platform. It supports feature toggles with complex activation strategies (gradual rollout, user targeting, environment-based). Testing with Unleash requires either mocking the client or using the in-process client for integration tests. SDK Setup # Node.js npm install unleash-client <span class="hljs-comment"
Test Automation
Video streaming applications involve multiple components: transcoding pipelines, manifest generation, CDN delivery, and player integration. Each layer needs testing. Testing the Transcoding Pipeline // services/transcoder.js import { spawn } from 'child_process' import path from 'path' export async function transcodeToHLS(inputPath, outputDir) { return new Promise((resolve, reject)
Test Automation
Statsig provides feature gates, dynamic configs, and A/B experiments. Its JavaScript SDK can be mocked or configured with local overrides for testing, though the approach differs slightly from GrowthBook due to Statsig's SDK design. SDK Setup npm install statsig-node # Node.js server npm install statsig-js <span
Test Automation
Multi-tenant data isolation can be implemented in several ways: shared tables with a tenant_id column, separate schemas per tenant, or separate databases per tenant. Each requires different testing approaches. This post focuses on testing shared-table and RLS-based isolation — the most common pattern in modern SaaS. Isolation Strategies Strategy Approach
