Environment Variables Support for Cypress Tests

You can specify the environment variables that you want to use for your Cypress tests via the configuration file, via the cypress.env.json file, or via the LambdaTest Cypress CLI. However, if we set environment variables via both LambdaTest CLI and cypress.env.json, the cypress.env.json file will be ignored and only the variables set via CLI will be set into environment variables. If you want to understand these methods, go through the document below.

1. Via the Configuration File​

a. Cypress 9

A sample cypress.json file:

{
......
    "env":{
        "CYPRESS_BASE_URL":"https://example.cypress.io/",
        "ACTIONS_URL": "commands/actions",
        "WINDOW_URL": "commands/window"
    },
......
}

b. Cypress 10

A sample cypress.config.js file:

module.exports = defineConfig({
  env: {
    'CYPRESS_BASE_URL':'https://example.cypress.io/',
    'ACTIONS_URL' : 'commands/actions',
    'WINDOW_URL': 'commands/window'
  },

You can use both of these in your test specifications file. An example of a test specifications file is: 

describe('Sample test', () => {
    it('test case - actions', () => {
      cy.visit(Cypress.env('CYPRESS_BASE_URL') + Cypress.env('ACTIONS_URL'))
      cy.wait(3000)
    })
    it('test case - window', () => {
        cy.visit(Cypress.env('CYPRESS_BASE_URL') + Cypress.env('WINDOW_URL'))
        cy.wait(3000)
    })
})

2. Via the cypress.env.json File​

{
    "CYPRESS_BASE_URL":"https://example.cypress.io/",
    "ACTIONS_URL" : "commands/actions",
    "WINDOW_URL": "commands/window"
}

3. Via the LambdaTest Cypress CLI​

You can also add your environment variables via the parameter --envs in the LambdaTest Cypress CLI. 

lambdatest-cypress run --envs "CYPRESS_BASE_URL=https://example.cypress.io/,ACTIONS_URL=commands/actions,WINDOW_URL=commands/window"
