It sounds as though you may want to use .its
cy.get('selector').its(propertyName).should('contain', 'string')
its needs to be chained off a previous command like get. You can also use this in a function as per Cypress's example
Cypress shows an example for DOM elements
Get the length property of a DOM element
cy .get('ul li') // this yields us a jquery object .its('length') // calls 'length' property returning that value .should('be.gt', 2) // ensure the length is greater than 2 })
You can access functions to then drill into their own properties instead of invoking them.
// Your app code // a basic Factory constructor const Factory = (arg) => { // ... } Factory.create = (arg) => { return new Factory(arg) } // assign it to the window window.Factory = Factory cy .window() // yields window object .its('Factory') // yields Factory function .invoke('create', 'arg') // now invoke properties on itv
You can drill into nested properties by using dot notation.
const user = { contacts: { work: { name: 'Kamil' } } } cy.wrap(user).its('contacts.work.name').should('eq', 'Kamil') // true
