Generate sample data within a fixture

Currently, I am in the process of working on a project that involves creating users and conducting tests on those users. To generate user data such as first name and last name, I am utilizing the faker tool. My goal is to create a user with these generated details, save them in a variable, and then access them during the testing phase.

I have experimented with various approaches, like calling the data from a function or another test, but I have been unsuccessful in passing the created data to subsequent tests.

Here is an excerpt of the code:

fixture "Create test data and pass them to the other tests"
  .page('url')
  .beforeEach(async (t) => {
    await t
      .typeText("#txtUserName", 'username')
      .typeText("#txtPassword", 'password')
      .click("#btnLogin");
  });

test("Create test data for add family tests", async (t) => {
  // Code snippet for creating test data
});

// More code segments...

test("Access created test data", async (t) => {
    // Code snippet for accessing created test data
});

Unfortunately, I cannot provide more than these code segments at this time. Your understanding is appreciated!

Data driven tests are not suitable for this scenario due to the high volume of users being created. Any assistance or suggestions would be greatly appreciated. Thank you!

Answer №1

It's difficult to provide a precise answer without an example. To better illustrate the issue, please create a simple sample.

Generally, it's important to separate test data from test files. Here are a few suggestions:

  1. You can store or generate all testing data separately and import it into test files
  2. Create a function that generates fake user information on demand and utilize it in your tests

Here is an example to demonstrate this concept:

test.js

import { users, createFakeUser } from './test-data';

fixture`fixture`
    .page`http://localhost/testcafe/index4.html`;

test('data object', async t => {
    for (let user of users) {
        await t
            .typeText('#name', user.name, { replace: true })
            .typeText('#email', user.email, { replace: true });
    }
});

test('function to get data', async t => {
    const user = createFakeUser();

    await t
        .typeText('#name', user.name)
        .typeText('#email', user.email);
});

test-data.js

import { faker } from '@faker-js/faker';

export function createFakeUser () {
    return {
        name:  faker.name.findName(),
        email: faker.internet.email()
    }
}

export const users = [
    createFakeUser(),
    createFakeUser()
];
