ic-test

ic-test is a command-line tool that helps you organize the test workflow for cross-chain projects on the Internet Computer (IC). It reads your dfx.json and foundry.toml files to automatically create testing base and uses existing frameworks (pocket-ic and foundry) to execute tests.

Overview

ic-test will:

• Read dfx.json to gather canister information.
• Read foundry.toml to gather contract information.
• Generate Rust type definitions from Candid (.did) files.
• Generate a contract interface from .sol definitions.
• Create access API to use existing .wasm canisters and .json contracts for testing.

Requirements

• Rust
• DFX SDK for local IC canister builds.
• Foundry if your tests involve EVM contracts.

Installation

You can install the tool via Cargo:

cargo install ic-test

Tool usage

Use ic-test by running one of its commands:

ic-test <COMMAND> [OPTIONS]

Create a new test project

ic-test new tests

• Creates a new test project in the tests folder.
• Looks for your canisters and contracts, then generates the necessary API bindings and a sample test file.
• Also creates an ic-test.json file to store generator configuration for future runs.
• Fails if the tests folder already exists.

Update/regenerate an existing test project

ic-test update

Reruns the generator based on the configuration in ic-test.json.

Manually add canister or contract

For a given Solidity contract name if will try to find its json implementation. Example:

ic-test add contract MyContract
