Welcome to the world of Solidity testing! Are you ready to level up your smart contract testing settings? PRBTest is your go-to solution, offering a powerful collection of testing assertions and logging utilities, set to improve your experience and effectiveness. But don’t worry! We’ll break down everything you need to know to get started smoothly.

What is PRBTest?

PRBTest is a modern testing framework designed specifically for Solidity. It serves as a drop-in replacement for DSTest with numerous features, including:

• Feature-packed assertions: From equalities to numerical comparisons.
• Type-rich assertions: Support for various data types like address, bytes, string, and more.
• Versioned releases: Avoid undesired updates that might break your test suites.
• Compatibility: Works seamlessly with Foundry and can also be used with Hardhat.
• Thorough testing: Every assertion is rigorously tested.

Installing PRBTest

Ready to install PRBTest? There are several approaches you can take based on your setup:

1. Using the Foundry Template

If you’re starting fresh, the simplest way is to utilize the Foundry template, which comes pre-configured with PRBTest.

2. Node.js Installation

For those comfortable with Node.js, follow this method:

bun add @prbtest

Next, remember to add the following to your remappings.txt file:

text@prbtest=node_modules/@prbtest/src

3. Git Submodules (Not Recommended)

If you prefer using Git submodules, here’s how:

forge install --no-commit PaulRBerg/prb-test@release-v0

Your .gitmodules file will automatically update with the necessary entry. Ensure you also update your remappings.txt:

text@prbtest=libprb-test

Usage of PRBTest

Once installed, it’s simple to use PRBTest in your contract. Just import it and inherit from PRBTest. Below is an analogy to visualize this process:

Imagine you have a toolbox that contains all essential tools. Installing PRBTest is like adding a new, specialized tool to your skeleton set—perfect for a specific job. Your toolbox can now assist you better in your projects.

pragma solidity =0.8.0;
import "@prbtest/PRBTest.sol";

contract MyTest is PRBTest {
    function testExample() external {
        vm.warp(block.timestamp + 100);
        emit Log("Hello World");
        assertTrue(true);
    }
}

Assertions

PRBTest provides a variety of assertions for testing features:

• assertTrue(bool)
• assertFalse(bool)
• assertEq() for multiple data types
• assertNotEq()
• assertAlmostEq()
• And many more…

Troubleshooting

If you run into issues during installation or usage, here are some common troubleshooting tips:

• Ensure your Solidity version is set to =0.8.0.
• Check if you have the necessary dependencies installed: Git, Foundry, Node.js, and Bun.
• If the installation fails, try clearing the cache of your package manager.
• Review the project structure—a misplaced file can lead to errors.
