Nemo.js Automation Skill

PayPal's Selenium-based test automation framework for Node.js.

Core Patterns

Basic Test (Mocha)

const Nemo = require('nemo');
const { expect } = require('chai');

describe('Login Flow', function() {
  this.timeout(30000);
  let nemo;

  before(async () => {
    nemo = await Nemo();
  });

  after(async () => {
    await nemo.driver.quit();
  });

  it('should login with valid credentials', async () => {
    await nemo.driver.get(nemo.data.baseUrl + '/login');
    const email = await nemo.view._find('#email');
    await email.sendKeys('user@test.com');
    const password = await nemo.view._find('#password');
    await password.sendKeys('password123');
    await nemo.view._find('button[type="submit"]').click();

    await nemo.view._waitVisible('.dashboard', 10000);
    const url = await nemo.driver.getCurrentUrl();
    expect(url).to.include('/dashboard');
  });

  it('should show error for invalid credentials', async () => {
    await nemo.driver.get(nemo.data.baseUrl + '/login');
    await nemo.view._find('#email').sendKeys('wrong@test.com');
    await nemo.view._find('#password').sendKeys('wrong');
    await nemo.view._find('button[type="submit"]').click();

    await nemo.view._waitVisible('.error', 5000);
    const error = await nemo.view._find('.error');
    const text = await error.getText();
    expect(text).to.include('Invalid');
  });
});

View Locators

await nemo.view._find('#css-id');                    // CSS
await nemo.view._find('.class-name');                // CSS class
await nemo.view._find('[data-testid="login"]');     // Data attribute
await nemo.view._find('xpath://button[@type]');     // XPath prefix
await nemo.view._waitVisible(locator, timeout);     // Wait + find
await nemo.view._finds('.items');                    // Find multiple

Configuration (nemo.config.json)

  "driver": {
    "browser": "chrome",
