Getting Started with Unit Tests

Install Prerequisites

• .NET Core SDK (>2.1.4)
• Visual Studio Code (>1.27)

Setup Project

Open command line / terminal and create a new C# unit test project with the command dotnet new console --name YOUR_PROJECT_NAME

Example:

dotnet new mstest --name MyProject

Add the Meadow unit testing framework package with the command dotnet add package Meadow.UnitTestTemplate

cd MyProject
dotnet add package Meadow.UnitTestTemplate

Create a directory named contracts to place your Solidity source files (the directory must be named contracts).

mkdir contracts

Add your Solidity source files to the contracts directory.

Here's an example hello world Solidity contract that we'll save to our contracts directory as HelloWorld.sol. Solidity source files must have the .sol file extension.

pragma solidity ^0.4.24;

contract HelloWorld {

    event HelloEvent(string _message, address _sender);

    function renderHelloWorld () public returns (string) {
        emit HelloEvent("Hello world", msg.sender);
        return 'Hello world';
    }

}
