Small Tester is a free Chrome extension designed for automating test cases and plans using natural language descriptions. It allows users to run manual test cases without needing to write code, making it an ideal tool for manual testers seeking to enhance their efficiency. Users can easily create test cases by describing actions and expected outcomes in simple language, and the extension leverages AI to execute these tests seamlessly.

To begin using Small Tester, users must obtain a free API key from a large language model such as Google Gemini. Once set up, tests can be run directly in the browser, with results indicating whether each test passes or fails based on the defined logic and expectations. This tool eliminates the complexity of traditional automation frameworks, providing a straightforward solution for those looking to automate testing without programming expertise.
