Testbook

Testbook is a no-code, AI-powered platform designed to automate web application testing, specifically targeting regression testing, UI comparison, and hybrid testing scenarios. The platform enables users to record their interactions with a web application through a Chrome extension, then play back those interactions automatically to verify that the application behaves as expected after changes. This eliminates the need for manual test case scripting and reduces the time required for repetitive testing tasks from roughly one week to just one hour. The core functionality revolves around a record-and-playback mechanism: users perform actions on a web page—clicking buttons, filling forms, navigating between pages—and Testbook captures every step as a test scenario. These recorded tests can be executed on demand, allowing teams to quickly check whether new code deployments break existing features. The platform also supports UI comparison, where screenshots of web pages before and after changes are compared pixel-by-pixel to detect unintended visual differences. This is particularly useful for catching layout shifts, missing elements, or styling issues that traditional functional tests might overlook. Testbook integrates seamlessly with popular cloud testing services such as Sauce Labs, BrowserStack, and TestingBot, enabling users to run tests across multiple browser and operating system combinations without maintaining their own device farm. This makes it suitable for cross-browser and cross-platform compatibility testing. Additionally, the platform supports hybrid testing, combining both functional and visual checks in a single workflow. For teams adopting continuous integration and delivery (CI/CD) pipelines, Testbook can be plugged into existing workflows to run automated
