How to get current date using cy.clock()

Question

How can i get the date in format dd/mm/yyyy using cy.clock() and put the date in a textfield.. I have seen most examples are getting the timestamp but i dont need the time. Just need the current day date.

I do not want to use custom command here. Thank you

Answer 1

You can use day.js to get the current date and format it accordingly.

const dayjs = require('dayjs')

//In test
cy.log(dayjs().format('DD/MM/YYYY'))  //Prints todays date 30/09/2021
cy.get('textfield').type(dayjs().format('DD/MM/YYYY')) //input today's date in DD/MM/YYYY format

The cy.clock() is about controlling the perceived date of the app.

From the examples,

Let the test run as at a certain date

const now = new Date(2017, 3, 14).getTime() // April 14, 2017 timestamp

cy.clock(now)
cy.visit('/index.html')
cy.get('#date').contains('2017-04-14')  

Typing into a field with a certain format

If you want to .type() a particular date string, convert with .toLocaleDateString()

const d = new Date()  // current date
// or
const d = new Date(2017, 3, 14)  // specific date

cy.get('input').type(d.toLocaleDateString('en-GB'))  // type in as 'dd/mm/yyyy'

Combining the two, e.g testing validation

// Set clock to a specific date
const now = new Date(2017, 3, 14).getTime() // April 14, 2017 timestamp
cy.clock(now)
cy.visit('/index.html')

// Type in an earlier date
const d = new Date(2017, 3, 13)
cy.get('input').type(d.toLocaleDateString('en-GB'))
  .blur()    // fire validation
  .should('contain', 'Error: Date entered must be a future date')
