  env: {
    PREFLIGHT_API_KEY: '[YOUR_API_KEY]'
  },
  "chromeWebSecurity": false,              // Enables PDF testing

Create an account on Preflight.com

• The API key will be generated for you automatically after creating account.
• Alternatively you can go to Account Settings / API to generate a new one.

Set API key in your test environment

• You can set key in code like Cypress.PreflightApiKey = '[YOUR_API_KEY]';
• Or set Cypress env in your cypress.config.js file.

env: {
  PREFLIGHT_API_KEY: '[YOUR_API_KEY]'
 }

Creating test

• Once you have the plugin installed and set up with the API key you can create your first test.
• Download Chrome extension Cypress Recorder from Preflight
• Log in and follow instructions to create your first test.

Example of generated test

describe('test', () => {
  it('YourWebApp - POM | Get/POM Autoheal | Email | Variables | checkpoint | Visual check', () => {
    let loginYourWebApp = new LoginYourwebappPOM();
    cy.viewport(1440, 900);
    cy.pf.initAutoheal('SbiHS3EhZ3A8');
    cy.visit('https://yourweb.app/#/login');
    loginYourWebApp.clickSignup();
    cy.pf.get('#pf-lesson-signup-0', {id:3}).type('{{name.firstName}}');
    cy.pf.get('#pf-lesson-signup-1', {id:4}).type('{{name.lastName}}');
    cy.pf.get('#pf-lesson-signup-2', {id:5}).type('{{generate.email}}');
    cy.pf.get('#pf-lesson-signup-3', {id:6}).type('123456');
    cy.pf.get('#pf-lesson-signup-4', {id:7}).click();
    cy.pf.openEmail('Verify your email');
    cy.pf.get('a', {iframe: '.data-box-content>iframe', id:9}).click();
    cy.pf.closeEmail()
    cy.pf.get('#pf-lesson-login-0', {id:11}).type('{{generate.email}}');
    cy.pf.get('#pf-lesson-login-1', {id:12}).type('123456');
    loginYourWebApp.clickSignIn(); // broken selector
    cy.pf.get('h1', {id:14}).should('include.text', 'Good morning, {{name.firstName[1]}} {{name.lastName[1]}}');
    cy.pf.get('.vue-apexcharts', {id: 15}).visualCheck('https://preflightuploadsdev.blob.core.windows.net/uploads/4450434e-e598-49d9-a102-3ec774ac7dec', {id:15});
    cy.pf.get('.max-w-xs>svg', {id:16}).click();
    cy.pf.get('[role="menu"]>button', {id:17}).click();
    cy.pf.get('h2', {id:18}).should('include.text', 'Sign in to your account');
  })
});

Convert code from v1 to v2

To convert your code to the new version you can use this JavaScript function

const convertCodeV1toV2 = (oldCode) => {
  let newCode = oldCode;

  // Replace "cy.initializeAutoheal" with "cy.pf.initAutoheal"
  newCode = newCode.replace(/cy\.initializeAutoheal/g, "cy.pf.initAutoheal");

  // Replace "cy.get" with "cy.pf.get" and add options object
  newCode = newCode.replace(/cy\.get\((.+?),(\s*)(\d+)\)/g, "cy.pf.get($1, {id:$3})");

  // Replace "cy.get" with "cy.pf.get" with iframe
  newCode = newCode.replace(/cy\.get\((.+?),(\s*)(\d+),(.+?)\)/g, "cy.pf.get($1, {id:$3, iframe:$4})");

  // Replace "cy.openEmail" with "cy.pf.openEmail"
  newCode = newCode.replace(/cy\.openEmail/g, "cy.pf.openEmail");

  // Replace "cy.closeEmail" with "cy.pf.closeEmail"
  newCode = newCode.replace(/cy\.closeEmail/g, "cy.pf.closeEmail");

  // Replace "cy.openPdf" with "cy.pf.openPdf"
  newCode = newCode.replace(/cy\.openPdf/g, "cy.pf.openPdf");

  // Replace "cy.closePdf" with "cy.pf.closePdf"
  newCode = newCode.replace(/cy\.closePdf/g, "cy.pf.closePdf");

  // Remove "cy.autoheal"
  newCode = newCode.replace(/cy\.autoheal\(\);/g, "");

  return newCode;
};

And use it like this

let newCode = convertCodeV1toV2(`
describe('test', () => {
  it('Dashboard | YourWebApp', () => {
    cy.viewport(1440, 900);
    cy.initializeAutoheal('16a2d8905e8c');
    cy.visit('https://yourweb.app/#/login');
    cy.get('.max-w>a', 2).click();
    cy.get('#broken', 3).type('{{name.firstName}}');
    cy.get('a', 9, '.data-box-content>iframe').click();
    cy.openEmail('Verify your email');
    cy.closeEmail();
    cy.openPdf('pdfName');
    cy.closePdf();
    cy.autoheal();
  })
});`)

console.log(newCode)
