In this Cypress testing tutorial, we will be doing the setup and installation on our local machine to get Cypress up and running.
One of the great things about Cypress is that using just one command you can get all the necessary packages installed to start writing your first test using Cypress. Let’s take a look at that –
To install Cypress locally, you need to run through the following steps –
Create a new npm project:
mkdir your_project_name && cd your_project_name
npm init -y to initialize your project
npm install cypress --save-dev
This will download and unzip the Cypress desktop client and install all the necessary packages for you.
Once Cypress is installed, you can open the Cypress desktop app by running the following command –
npx cypress open
This will open up the Cypress app for you and list all the initial pre-built tests –
Click on any of the pre-built example tests and it will launch up the Cypress Test Runner and start running all the tests –
When you install Cypress, it will setup the folder structure for you automatically –
- Fixtures: used to store all the external static data for your tests i.e. JSON data files, images, etc…
- Integration: this is where all your test files are stored
- Plugins: You can extend Cypress functionalities by taking advantage of Cypress built as well as community-built plugins
- Support: In the support folder, you can store custom commands which can be utilized by your tests
- Cypress.json: this is the default configuration file where you can store information such as baseUrl, env, port, etc…
