What TestZeus Hercules is
TestZeus Hercules is an open-source autonomous agent for end-to-end software testing. It accepts tests in Gherkin format and returns results in XUnit format, supporting UI and API scenarios as well as security, accessibility, visual, integration and regression testing. The maker says it can run without complex scripts or locator work and can autoheal toward a testing goal. Users can set it up with pip or Docker and run it locally or in a deployment pipeline. Browser, API and database tools are included, and additional tools can be attached. Listed language model options include OpenAI, Groq, Llama, Mistral and Anthropic. Hercules records execution video and network logs; the maker says it can perform more than 15 security tests and is grounded in Salesforce terminology. It supports API, Linux, self-hosted, web and Windows environments. The free Platform Access plan includes 30 Scenario Runs per month. A Scenario Run is one scenario executed once: started failed tests count, while tests that never start do not.
