Cypress.platform returns the underlying OS name, as returned from Node’s os.platform().

Even though Cypress runs in the browser, it automatically makes this property available for use in your tests.

Syntax

Cypress.platform // 'darwin'

Examples

Conditionals

it('has JSON files', function () {
  // if windows do one thing, else do another
  const cmd = Cypress.platform === 'win32' ? 'dir *.json' : 'ls *.json'

  cy.exec(cmd)
    .its('stdout')
    .should('include', 'package.json')
})
