Pick your stack. Meet testers who live in it.
Every hub gathers open questions, solved answers and top helpers for a single tool — plus focused prep from SoftwareTestPilot.
Browser automation
Playwright
Modern cross-browser end-to-end automation. Fast selectors, auto-waits, tracing, and first-class TypeScript support — the default for new QA teams in 2026.
Selenium
The most widely deployed browser automation stack. Selenium 4 + Grid still runs the largest enterprise QA suites in the world.
Cypress
Component and E2E tests with a tight developer feedback loop. Great DX, strong component testing, opinionated architecture.
API
Postman
The lingua franca of API testing. Collections, monitors, and Newman keep contract checks running everywhere from a laptop to CI.
REST Assured
Java-first API testing DSL. Ideal for teams already invested in JUnit / TestNG that need fluent, contract-heavy request assertions.
API Testing
Contract, integration, and end-to-end API tests. Cover authentication, edge cases, and negative flows — the highest-ROI layer of the pyramid.
Performance
JMeter
Battle-tested load and performance testing. Rich protocol coverage, distributed load, and mature reporting — still the enterprise default.
k6
JavaScript-scripted load testing built for developers. Cloud-native, CI-friendly, and great for shifting performance left.
