Test Sprite - Intelligent Automated Testing Engine

Test Sprite MCP server is an intelligent integration that connects an IDE's AI assistant to a powerful automated testing engine. It manages the full testing lifecycle: analyzing code, generating test plans, writing executable tests, running them in the cloud, delivering reports, and even autofixing bugs, all through simple natural language prompts. It supports many IDEs.

Step-by-step Process (using Anti-gravity IDE as an example):

1. Ensure Node.js version 22 or higher is installed.
2. Visit testsprite.com, sign up, and obtain an API key from the dashboard settings.
3. In Anti-gravity, open the editor's agent panel, select "manage MCP servers," and then "view raw config."
4. Add a specific configuration to the mcp_config.json file, replacing a placeholder with the copied API key.
5. Save and restart the IDE if necessary. Success is indicated by no errors and the AI assistant recognizing Test Sprite tools.
6. To test, open a project, run the app locally, and in the chat, type "can you test this project with test sprite?"
7. A config page opens where the user selects a mode, adds a local URL, provides credentials if needed, uploads a basic PRD, and submits. The agent then automatically handles the rest. Test Sprite offers paid plans for autonomous testing integration.
