Setup Cypress coverage on typescript Next.js 12
Create coverage test results By: Dániel Sipos onTo set up Cypress for a Next.js project, you can follow these steps:
Install Cypress using npm:
npm install --save-dev cypress
Initialize Cypress by running the following command:
npx cypress init
Modify the package.json file to add a script for running Cypress tests:
"scripts": {
"cypress:open": "cypress open",
"cypress:run": "cypress run"
},
In your Next.js server.js file, add the following code to start the server in development mode when running Cypress tests:
if (process.env.CYPRESS_ENV === 'development') {
require('next/dist/server/next')().start(3000)
}
Create a test file in the cypress/integration directory. For example, you could create a file called test.js with the following content:
describe('My test', () => {
it('visits the homepage', () => {
cy.visit('http://localhost:3000')
})
})
Run the Cypress test runner using the following command:
npm run cypress:open
This will open the Cypress test runner, where you can view and run your tests.
