Jest Unit Testing Examples

Welcome to the world of Jest testing!

Our mission is to break you into this world gently. So let's begin...

Pre-requisites

• You will need to have access to the command-line, for Linux/Mac a Terminal or on Windows it will be a command prompt (cmd)
• You will need to have git installed: http://git-scm.com/downloads
• NodeJS & npm - https://nodejs.org or via NVM (https://github.com/creationix/nvm)
• yarn [optional] - https://yarnpkg.com

Download

Just use git to clone the ssh version:

git clone [email protected]:jhbsk/jest-unit-testing-examples.git

Or use git to clone the https version:

git clone https://github.com/jhbsk/jest-unit-testing-examples.git

Or download the .zip archive and unzip it to the folder jest-unit-testing-examples:

https://github.com/jhbsk/jest-unit-testing-examples/archive/master.zip

Installation

On the command-line or Terminal, navigate to the root of the directory which you downloaded and run:

• If you have npm: npm install
• If you have yarn: yarn install

Running tests

Here are a few commands you should now be able to run:

• Run Jest tests once: npm test or yarn test
• Run Jest in watch mode (great for TDD): npm run test:watch or yarn test:watch
