I am trying to use fakerjs in my cypress tests to randomly generate fake data for my forms. I have tried exporting it in support/index.js which did not work.

Is there any standard way to add fakerjs to all cypress specs instead of adding it in every spec file?

First off, what's wrong with importing it in every spec?

That being said, you can do this:

cypress/support/index.js:

cy.faker = require('faker');

your specs:

it(`test`, () => {
    const words = cy.faker.lorem.words();
});

    that's not working, when we call we calll cy.faker it is losing reference to existing selector, can we make it as utility, like we have lodash(Cypress._), moment.(Cypress.moment).etc – user1614862 Oct 14 '19 at 23:55
  • Not sure what "it is losing reference to existing selector" means. – dwelle Oct 15 '19 at 09:01
  • when I try to use faker like cy.get('#myinput').type(cy.faker.firstName()), it gives me an error that cy is not referring valid input to type – user1614862 Oct 15 '19 at 11:28
  • that has nothing to do with `cy.faker` but rather with `cy.type`. Solve the `cy.type` error (likely because the `cy.get()` didn't find an actionable element), and it'll work. – dwelle Oct 15 '19 at 12:30

    cy.type() is working if I have simple text cy.get('#myinput').type('abc'), but it is failing with above error if I use cy.faker.firstName(), anyway, I am able to achieve this without cy. prefix, something like const faker = require('faker') and in my actual statement cy.get('#myinput').type(faker.firstName()). THANKS for the clue. – user1614862 Oct 15 '19 at 19:59

    That doesn't make sense to me. Btw, `faker.firstName()` shouldn't work - the API is `faker.name.firstName()` (but maybe you're not on latest version). – dwelle Oct 15 '19 at 21:02

I tried it and found very simple. Steps are mentioned below,

1- require faker

const faker = require("faker");

2- Use where you want like this

var firstName = faker.Name.findName(); // Variable declaration
cy.get("#firstName").type(firstName); // Use in locator

I hope it would help :)

For reference javascript :- Https://zetcode.com/javascript/fakerjs/

You can use these in cypress:

npm i faker

const faker = require("faker"); 

let username = faker.name.findName()
let email = faker.internet.email()
let password = faker.internet.password()

Use all these in single specs file.
