Signup

Learn about custom signup commands.

We'll cover the following

Introduction

At least half of RealWorld features require a user to be authenticated. By default, Cypress does not allow you to share the state between the tests (which would otherwise be an anti-pattern). We need to transform the signup process into something usable by every test: a Cypress custom command.

A Cypress Custom Command is a function that can be called from the global cy object. We are going to create a cy.signupV1() command to be run before every other test.

Steps to create a new Cypress custom command:

  • Create a new file containing the code of the command itself in the cypress/support directory. The file should be: cypress/support/signup/signup-v1.js.

  • Add the wrapper of the code.

Cypress.Commands.add("signupV1", (/* the params of the command */) => {
  /* the code of the command */
});
  • Import the newly created file from the cypress/support/commands.js file.
import "./signup/signup-v1";
  • Start writing a new test that calls the cy.signupV1() command.
context("Whatever test", () => {
  it("Should leverage the custom registration command", () => {
    cy.signupV1();
  });
});
  • Run the test!

While the new command does nothing at the moment, it will be the foundation of cy.signupV1 command.

First signup command

The core of the command is the same as the following code.
