Run manual test cases with AI: describe steps and expected results in plain English. No Selenium, Playwright or coding needed. This Chrome extension lets you automate test cases and test plans using natural language descriptions of steps and expected results. To get started, sign in with a free AVRM-Soft account, which gives you free credits for the built-in AI models. Or use your own API key for a large language model (LLM), such as Google Gemini, which you can obtain for free via Google AI Studio (https://aistudio.google.com/). Simply input your manual test cases and test plans through the extension's interface. Once set up, you can execute your tests directly in the current browser tab with the 'Run' button, and view the results. Each test will either pass or fail based on its logic, the tested interface and data, and the expected outcome.
No need to use Selenium, Playwright, Cypress, Puppeteer, or any other automation tools that require programming skills. Just describe your test cases in natural language - the AI will handle the rest. This tool is especially useful for manual testers looking to automate their tests without writing code. It can also serve as an AI-powered web automation agent.
Simple steps to get started: 1. Sign in to the extension with a free account to receive free credits. Alternatively, go to Google AI Studio (https://aistudio.google.com/) and get a free API key. Feel free to obtain a key in another place or use an existing one. 2. If you use your own key: open the extension's Options page, select Google Gemini, enter your API key, and save. 3. In the main window, create test cases with one or more steps. For each step, write the action and expected result in natural language (you can use any language supported by the LLM). 4. Run the test — it will execute in the active browser tab. 5. Review the results. If needed, refine your steps or expected results for better accuracy and rerun the case.
Free credits are topped up every month, and using your own API key is always free. If you need more, paid plans with extra credits and additional AI models are available at https://avrmsoft.com/smalltester.
