How to fill out and submit forms with Cypress

Welcome to the “Pinches of Cypress” series! 🧂

In this series of content in text format with code snippets, you will learn several tricks of the automated testing framework cypress.io, to make your life easier in writing test scripts.

I will start with something simple, and we will evolve throughout the series, okay?

Let's say you are testing an application that sells event tickets.

In this example application, for a user to buy a ticket, he must fill in some mandatory data, and after submitting the form, he will receive a success message.

Let's say that the mandatory fields are as follows:

• Full name
• Email
• Checkbox that you agree to the terms of service

Let's also imagine that the elements above have unique IDs.

The test would look something like this:

describe('Online tickets selling app', () => {
  beforeEach(() => {
    cy.visit('https://example.com/tickets')
  })

  it('successfully orders a ticket', () => {
    cy.get('#fullName')
      .should('be.visible')
      .type('John Doe')
    cy.get('#email')
      .should('be.visible')
      .type('john-doe@example.com')
    cy.get('#iAgree')
      .should('be.visible')
      .check()
    cy.get('button[type="submit"]')
      .should('be.visible')
      .click()

    cy.contains('You will receive an email to finish the purchase.')
      .should('be.visible')
  })
})

Note that before typing (type), checking (check), or clicking on elements (click), I am ensuring that they are visible (.should('be.visible')). This makes the test more robust.

Finally, I verify that the text "You will receive an email to finalize your purchase" is contained in some element and is visible.

That's it!

I hope you enjoyed it, and stay tuned for the next content in the series. 👋
