Generates NightwatchJS E2E tests in JavaScript. Integrated test runner with Selenium WebDriver, built-in assertions, and page objects. Use when user mentions "Nightwatch", "NightwatchJS", "nightwatch.conf.js". Triggers on: "Nightwatch", "NightwatchJS", "nightwatch test".

The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

Core Patterns

Basic Test

module.exports = {
  'Login with valid credentials': function(browser) {
    browser
      .url('http://localhost:3000/login')
      .waitForElementVisible('#email', 5000)
      .setValue('#email', '[email protected]')
      .setValue('#password', 'password123')
      .click('button[type="submit"]')
      .waitForElementVisible('.dashboard', 10000)
      .assert.containsText('.welcome', 'Welcome')
      .assert.urlContains('/dashboard')
      .end();
  },

  'Login with invalid credentials shows error': function(browser) {
    browser
      .url('http://localhost:3000/login')
      .waitForElementVisible('#email', 5000)
      .setValue('#email', '[email protected]')
      .setValue('#password', 'wrong')
      .click('button[type="submit"]')
      .waitForElementVisible('.error-message', 5000)
      .assert.containsText('.error-message', 'Invalid credentials')
      .end();
  }
};

Page Objects

// pages/loginPage.js
module.exports = {
  url: '/login',
  elements: {
    emailInput: '#email',
    passwordInput: '#password',
    loginButton: 'button[type="submit"]',
    errorMessage: '.error-message',
  },
  commands: [{
    login(email, password) {
      return this
        .setValue('@emailInput', email)
        .setValue('@passwordInput', password)
        .click('@loginButton');
    }
  }]
};

// tests/loginTest.js
module.exports = {
  'Login test': function(browser) {
    const login = browser.page.loginPage();
    login.navigate()
      .login('[email protected]', 'password123');
    browser.assert.urlContains('/dashboard');
  }
};

Assertions

browser.assert.visible(selector);
browser.assert.not.visible(selector);
browser.assert.containsText(selector, 'text');
browser.assert.urlContains('/path');
browser.assert.titleContains('Page Title');
browser.assert.elementPresent(selector);
browser.assert.cssClassPresent(selector, 'active');
browser.assert.value('#input', 'expected');
browser.assert.attributeEquals(selector, 'href', '/link');
browser.assert.elementsCount('li', 5);

        'LT:Options': {
          platform: 'Windows 11',
          build: 'Nightwatch Build',
          name: 'Login Tests',
          user: process.env.LT_USERNAME,
          accessKey: process.env.LT_ACCESS_KEY,
          video: true, console: true, network: true
        }
