Lab 4 — Unit Testing & Mocking

Framework: Jest

Testing custom JavaScript classes and async functions with mocks and dependency injection.

What's tested:

• UserService — greeting with mocked getFullName dependency
• asyncHello, computeValue, asyncError — async/await patterns
• ApiClient — mocked fetch() calls
• ApiHelper — invalid data validation
• calculateFinalPrice — order pricing with discount service injection
• OrderProcessor — async currency conversion with mocks

// Mocking a dependency
const mockGetFullName = jest.fn().mockReturnValue('John Doe');
const service = new UserService(mockGetFullName);
expect(service.greet()).toBe('HELLO, JOHN DOE!');

Lab 5 — Browser Automation Basics

Framework: Selenium WebDriver · Jest · Chrome Target: wikipedia.org

End-to-end browser tests using locators: ID, CSS, XPath, LinkText.

Test cases:

• ✅ Search box and logo are present on the homepage
• ✅ Search for "Selenium" navigates to the correct article
• ✅ Article heading verified via XPath (//h1[@id="firstHeading"])
• ✅ All navigation links start with https://en.wikipedia.org
• ✅ Click "Oxygen" link, wait for navigation, check CSS color of heading

const searchBox = await driver.findElement(By.id('searchInput'));
await searchBox.sendKeys('Selenium');
await searchBox.submit();
await driver.wait(until.titleContains('Selenium'), 5000);

Lab 6 — Page Testing with Selenium

Framework: Selenium WebDriver · Jest · Chrome Target: automationexercise.com

Testing core UI elements of a practice e-commerce site. 9 test cases across multiple test files.

Test cases (mainPage.test.js + others):

• ✅ Top navigation menu (ul.nav.navbar-nav) is present
• ✅ Logo alt attribute equals "Website for automation practice"
• ✅ "Signup / Login" button contains text "Signup"
• ✅ + 6 additional test cases across other test files

const logo = await driver.findElement(
  By.css('img[alt="Website for automation practice"]')
);
expect(await logo.getAttribute('alt')).toBe('Website for automation practice');

Lab 7 — Real-World E-Commerce Testing

Framework: Selenium WebDriver · Jest · Chrome Target: hotline.ua

Testing search functionality on a real Ukrainian e-commerce platform with dynamic content and extended timeouts.

Test files:

• search.test.js — search field visibility and result loading after query
• buyButton.test.js — search for "ноутбук", verify .list-item results appear

const searchBox = await driver.wait(
  until.elementLocated(By.css('#autosuggest input[type=text]')), 20000
);
await searchBox.sendKeys('ноутбук', '\n');
const results = await driver.wait(
  until.elementLocated(By.css('.list-item')), 20000
);
expect(results).toBeTruthy();

Lab 8 — BDD with Cucumber & Gherkin

Framework: Cucumber · Selenium WebDriver · Chrome Target: automationexercise.com

Behavior-Driven Development using .feature files with Given/When/Then syntax and step definitions in JavaScript.

Scenarios (testcases.feature):

Scenario	Description
TC02	Login with correct email and password
TC04	Register new user with full account details form
TC05	Register with existing email → error message
TC06	Navigate to Contact Us page

Feature file example:

Scenario: TC04 Register User
  Given I open the browser
  When I navigate to the homepage
  And I click on Signup Login
  And I enter name "LogoutUser" and email "unique"
  And I click Signup button
  Then I should see "ENTER ACCOUNT INFORMATION"
  When I fill account details
  And I click Create Account button
  Then I should see "ACCOUNT CREATED!"
  And I close the browser

Lab 9 — API Testing with Pactum

Framework: Jest · Pactum Target: Multiple public REST APIs

Testing 4 public APIs: status codes, response structure, data types, and parametrized tests.

Test suites:

Suite	API	Tests
Currency API	currency-api.pages.dev/v1	Currencies list, EUR→USD/UAH rates, 404 for unknown currency
Bank Holidays API	gov.uk/bank-holidays.json	Events count > 0, Easter date format (YYYY-MM-DD)
Cat Facts API	catfact.ninja	Breed structure, fact format, ?limit=3 param, response headers
Dictionary API	dictionaryapi.dev	Example usage for 5 words: hello, world, science, test, love

// Parametrized test across multiple words
const words = ['hello', 'world', 'science', 'test', 'love'];
for (const word of words) {
  test(`Check examples for word "${word}"`, async () => {
    const res = await pactum.spec()
      .get(`https://api.dictionaryapi.dev/api/v2/entries/en/${word}`)
      .expectStatus(200);
    const hasExample = res.json[0].meanings
      .some(m => m.definitions.some(d => d.example));
    expect(hasExample).toBe(true);
  });
}
