Day 4 of 100daysofcode : Mastering Selenium Locators

Locators in Selenium are used to identify and interact with web elements on a webpage, such as buttons, input fields, or links. They enable automated scripts to perform actions like clicking, typing, or retrieving information, making them essential for effective web automation.

Here’s a list of all the locators used in Selenium:

1. ID
2. Name
3. Class Name
4. Tag Name
5. Link Text
6. Partial Link Text
7. CSS Selector
8. XPath
9. DOM Locator (via JavaScript execution)

These locators provide a variety of ways to identify and interact with web elements depending on the structure of the webpage.

Day 5 of 100daysofcode : So, how do locators really work using Selenium?

Locators in Selenium work by identifying elements on a webpage using their unique attributes or properties, such as id, name, class, or tag structure.

Selenium communicates with the browser’s DOM (Document Object Model) to search for elements that match the specified locator. Once an element is located, Selenium enables interactions like clicking, typing, or extracting data.

By combining locators with Selenium’s powerful methods, testers can precisely target elements even on dynamic and complex web pages.

1. ID Locator

• Description: Uses the id attribute of an HTML element.
• Syntax:

element = driver.find_element(By.ID, "element_id")

• Advantages:
  • Unique within a page.
  • Fast and reliable.

2. Name Locator

• Description: Uses the name attribute of an HTML element.
• Syntax:

element = driver.find_element(By.NAME, "element_name")

• Advantages:
  • Simple and effective if name attributes are unique.
• Disadvantages:
  • May not always be unique.

3. Class Name Locator

• Description: Uses the class attribute of an HTML element.
• Syntax:

element = driver.find_element(By.CLASS_NAME, "class_name")

• Advantages:
  • Works well for elements with specific styling.
• Disadvantages:
  • Fails when multiple elements share the same class.

4. Tag Name Locator

• Description: Uses the HTML tag name (e.g., input, button).
• Syntax:

element = driver.find_element(By.TAG_NAME, "tag_name")

• Use Case:
  • Retrieving collections of elements like all links (<a> tags) on a page.

5. Link Text Locator

• Description: Locates links based on their text.
• Syntax:

element = driver.find_element(By.LINK_TEXT, "Link Text")

• Use Case:
  • Ideal for links with unique text.
• Disadvantages:
  • May not work well with long or dynamic text.

6. Partial Link Text Locator

• Description: Locates links using partial text match.
• Syntax:

element = driver.find_element(By.PARTIAL_LINK_TEXT, "Partial Text")

• Use Case:
  • Useful when link text is too long or dynamic.

7. CSS Selector

• Description: Uses CSS selectors to locate elements.
• Syntax:

element = driver.find_element(By.CSS_SELECTOR, "css_selector")

• Advantages:

  • Extremely flexible and powerful.
  • Supports complex matching patterns.

• Examples:

  • By class: ".classname"
  • By ID: "#id"
  • By attribute: [type='submit']

Locators in Selenium are used to identify web elements on a webpage. They are a fundamental part of Selenium’s interaction with web applications. Here’s a detailed overview of the commonly used locators in Selenium:

from selenium import webdriver
from selenium.webdriver.common.by import By

# Initialize the WebDriver
driver = webdriver.Chrome()

# Open the practice login page
driver.get("https://practicetestautomation.com/practice-test-login/")

# Locate the username and password fields
username_field = driver.find_element(By.ID, "username")
password_field = driver.find_element(By.ID, "password")

# Enter credentials
username_field.send_keys("student")
password_field.send_keys("Password123")

# Locate and click the login button using a CSS Selector
login_button = driver.find_element(By.CSS_SELECTOR, "button[type='submit']")
login_button.click()

# Validate login by checking the URL or a success message
success_message = driver.find_element(By.TAG_NAME, "h1")
assert success_message.text == "Logged In Successfully", "Login failed!"

# Close the browser
driver.quit()

Day 13 of 100daysofcode : Here are 10 tips and tricks to effectively use Cypress for automation testing:

1. Use Custom Commands

• Simplify repetitive tasks by defining custom commands in the cypress/support/commands.js file.
• Example:

  Cypress.Commands.add('login', (username, password) => {
    cy.visit('/login');
    cy.get('#username').type(username);
    cy.get('#password').type(password);
    cy.get('#submit').click();
  });
  

• This keeps your test cases clean and reusable.

2. Leverage Cypress Fixtures

• Use the fixtures folder to store reusable test data in JSON files.
• Example:

  cy.fixture('user').then((user) => {
    cy.get('#username').type(user.username);
    cy.get('#password').type(user.password);
  });
  

3. Take Advantage of Assertions

• Cypress has built-in assertions that simplify verifying UI elements.
• Example:

  cy.get('.alert').should('be.visible').and('contain', 'Success');
  

4. Use Cypress Selectors Carefully

• Use data-* attributes for stable selectors instead of classes or IDs that may change.
• Example:

  <button data-cy="submit-btn">Submit</button>
  

  cy.get('[data-cy=submit-btn]').click();
  

5. Handle Network Requests with cy.intercept

• Mock API requests and responses to test edge cases or scenarios.
• Example:

  cy.intercept('GET', '/api/users', { fixture: 'users.json' }).as('getUsers');
  cy.visit('/users');
  cy.wait('@getUsers');
  

6. Utilize Cypress Plugins

• Extend functionality using Cypress plugins like cypress-axe for accessibility testing or cypress-file-upload for file uploads.
• Example with cypress-file-upload:

  cy.get('input[type="file"]').attachFile('file-to-upload.pdf');
  

7. Use .then() for Synchronous Commands

• Chain asynchronous Cypress commands for cleaner test flows.
• Example:

  cy.get('#price').invoke('text').then((priceText) => {
    const price = parseFloat(priceText);
    expect(price).to.be.greaterThan(0);
  });
  

8. Take Screenshots and Videos

• Use cy.screenshot() for debugging or visual regression testing.
• Enable video recording in the cypress.config.js file for CI/CD environments.

9. Parallelize Tests for Speed

• Leverage Cypress Dashboard to split test execution across multiple machines or threads.
• Example: Use the --parallel flag:

  npx cypress run --record --parallel
  

10. Debugging with Cypress

• Use cy.pause() to pause tests at specific steps.
• Use .debug() to inspect elements in the browser.
• Leverage the built-in Cypress debugger with the browser’s Developer Tools.

By incorporating these tips into your Cypress workflow, you can write more efficient, maintainable, and robust automated tests.

Day 14 of 100daysofcode : Cypress Setup

Setting up Cypress for automation testing is straightforward and involves a few steps. Below is a detailed guide:

Step 1: Install Node.js

Cypress requires Node.js to run. If you don’t have Node.js installed:

1. Download it from Node.js official website.
2. Install it by following the prompts.

Step 2: Create a Project Directory

1. Open your terminal or command prompt.
2. Create a new project folder for your automation tests:

   mkdir cypress-automation
   cd cypress-automation
   

3. Initialize a new Node.js project:

   npm init -y
   

   This creates a package.json file to manage your project dependencies.

Step 3: Install Cypress

Run the following command to install Cypress:

npm install cypress --save-dev

This will add Cypress as a development dependency in your project.

Step 4: Open Cypress

After installation, you can open Cypress using the following command:

npx cypress open

This command will:

• Launch the Cypress Test Runner.
• Create a default folder structure (cypress/) in your project directory:
  • cypress/e2e: Place your test files here.
  • cypress/fixtures: Store static data (e.g., JSON files) for your tests.
  • cypress/support: Add custom commands or reusable logic here.

Step 5: Write Your First Test

1. Inside the cypress/e2e folder, create a new test file, for example:

   touch cypress/e2e/sample_test.cy.js
   

2. Add a simple test in the file:

   describe('My First Test', () => {
     it('Visits the Cypress website', () => {
       cy.visit('https://www.cypress.io');
       cy.contains('Features').click();
       cy.url().should('include', '/features');
     });
   });
   

Step 6: Run Tests

1. Start Cypress Test Runner:

   npx cypress open
   

2. Select the test file you created (sample_test.cy.js) and run it.

Step 7: Configure Cypress (Optional)

You can customize Cypress settings in the cypress.config.js or cypress.config.ts file created in your project root. For example, to set a base URL for your tests:

const { defineConfig } = require('cypress');

module.exports = defineConfig({
  e2e: {
    baseUrl: 'https://example.com',
    setupNodeEvents(on, config) {
      // implement node event listeners here
    },
  },
});

Step 8: Add Cypress to Scripts (Optional)

To make running tests easier, add Cypress commands to your package.json scripts:

"scripts": {
  "cypress:open": "cypress open",
  "cypress:run": "cypress run"
}

Now, you can run Cypress with:

• npm run cypress:open: Opens the Test Runner.
• npm run cypress:run: Runs tests in headless mode.

Step 9: Integrate Cypress with CI/CD (Optional)

To run Cypress tests in CI/CD pipelines, you can use the cypress run command. Add this step to your CI/CD configuration file (e.g., GitHub Actions, Jenkins, or CircleCI).

Step 10: Explore More Features

• Assertions: Use Chai.js assertions built into Cypress.
• Fixtures: Load external test data using cy.fixture().
• Custom Commands: Add reusable logic in cypress/support/commands.js.

For more details, visit the Cypress Documentation.

Day 15 of 100daysofcode : Cypress Test for Login Functionality

describe('Login Page Test', () => {
  it('should allow a user to log in successfully', () => {
    // Visit the login page
    cy.visit('https://example.com/login');

    // Enter username and password
    cy.get('input[name="username"]').type('testuser');
    cy.get('input[name="password"]').type('Password123');

    // Click the login button
    cy.get('button[type="submit"]').click();

    // Assert the user is redirected to the dashboard
    cy.url().should('include', '/dashboard');
    
    // Assert the welcome message is displayed
    cy.contains('Welcome, Test User!').should('be.visible');
  });
});

Key Points:

1. cy.visit(): Navigates to the specified URL.
2. cy.get(): Finds elements using CSS selectors.
3. type(): Types text into an input field.
4. click(): Clicks on a button or element.
5. Assertions:
   • should('include') verifies the URL.
   • should('be.visible') confirms an element is visible.

This example assumes that the login page contains inputs with the names username and password and a button with type="submit". You can adapt the selectors and assertions based on your application.
