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);
