To get started with this project, you will need to have Node.js and npm (Node Package Manager) installed.

First, clone the repository and navigate to the project directory:

git clone https://github.com/devonshigaki/unit-tests.git
cd unit-tests

Then, install the required dependencies:

npm install

To run the Jest tests, simply use the following command:

npm test

This will execute all test files located in the tests directory and display the results in the terminal.

Adds two numbers and returns the result.

Example:

const { add } = require('./src/math');
console.log(add(2, 3)); // 5

Subtracts the second number from the first and returns the result.

Example:

const { subtract } = require('./src/math');
console.log(subtract(5, 3)); // 2

Asynchronously fetches data and returns it.

Example:

const { fetchData } = require('./src/math');
fetchData().then(data => console.log(data)); // 'data'
