We've introduced a new AI-powered script that automatically generates a comprehensive baseline test suite for the multi-contract interactions in this Arbitrum Stylus example.
> impact
This update adds a new script, `pnpm test:generate`, designed to streamline the testing process for multi-contract Stylus applications. This script leverages a Large Language Model (LLM) to analyze the Rust source code of both the `polls-contract` and the `voter-registry-contract`. Based on this analysis, it automatically generates a suite of integration tests written in TypeScript using the ethers.js library, which are then saved into the project's test directory.
The primary motivation for this feature is to reduce the manual effort and complexity involved in writing thorough tests for cross-contract interactions. Previously, developers had to meticulously map out all success paths, failure conditions like double voting or unregistered voter access, and various edge cases. This manual process is not only time-consuming but also prone to human error, potentially leaving critical interaction bugs undiscovered until later in the development cycle.
The impact on developers is a significant boost in productivity and confidence in their contract logic. By automating the creation of a foundational test suite, this tool saves valuable development time and provides immediate, broad test coverage for key functions like `create_poll`, `vote`, and `register_voter`. Developers can use the generated tests as a solid starting point, allowing them to focus on writing more complex, application-specific tests rather than boilerplate code, ultimately leading to more robust and secure dApps.

# To generate and run your AI-powered test suite, follow these steps in your terminal.
# 1. First, ensure you have all project dependencies installed.
# This command will set up the necessary libraries, including ethers.js for testing.
pnpm install
# 2. Run the new AI test generation script.
# This command reads the Rust source from both contracts, sends it to an LLM,
# and writes the generated TypeScript integration tests to the `test/` directory.
pnpm test:generate
# 3. Once the tests are generated, you can execute them.
# This will compile the Stylus contracts, deploy them to a local node,
# and run the AI-generated test suite to verify the multi-contract interactions.
pnpm test
