The aeproject framework offers a comprehensive toolkit for developers, streamlining contract deployment, testing, and project management with built-in templates and utilities. Multiple testnet environments are available for testing applications under various network conditions, allowing developers to experiment without risking real funds. The faucet service enables easy access to test tokens for development purposes, removing common barriers to experimentation. These development support services create a seamless environment for building, testing, and iterating on decentralized applications before mainnet deployment. The following sections provide detailed guidance on leveraging these development tools and testing environments effectively. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.aeternity.com/aeternity-developer-tools/development-infrastructure/testing-and-deployment.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
