What Is Regression Testing? Explained in 75 Seconds

Regression testing means re-running your existing tests after every code change to make sure features that already worked still work. ▶ Scale your regression suites on TestMu AI: https://www.testmuai.com/automation-cloud/ Every time you update a website, you risk breaking something that was already working. Change the checkout, and you still need to retest login, search, cart and payments, because every flow is connected. That's regression testing. But once your suite grows to 1,000+ tests after every release, doing it manually gets slow and hard to maintain. Here's how TestMu AI (formerly LambdaTest) helps you scale it: 🔹 KaneAI: create tests in plain English, like "Test checkout with an expired credit card" 🔹 Bring your existing Selenium, Cypress, Playwright or Appium suites 🔹 Run across thousands of browser, OS and real-device combinations 🔹 SmartUI: catch visual changes by comparing builds against a baseline 🔹 HyperExecute: run tests in parallel, up to 70% faster than sequential runs Ship changes with confidence. #RegressionTesting #SoftwareTesting #TestAutomation #QATesting #TestMuAI
