Introduction

Test Automation Framework helps software testing teams streamline the test automation process, improve test efficiency, and enhance test coverage.

An effective test automation framework should be designed to meet specific testing needs, promote code reusability, and ensure the reliability of automated tests.

Prerequisite

In this newsletter, we will be using:

• Java as the programming language

• TestNG as the assertion framework

• Maven as the build automation tool

• Selenium WebDriver as the browser automation tool

• Eclipse as the IDE

Maven & TestNG Project Setup

1. Click on “Create New Project” and select “Maven Project”.

   

2. Filter by “maven-archetype-quickstart” and select the one with groupId “org.apache.maven.archetypes” and click “Finish”.

   

3. Basic folder structure should be ready

   

4. Convert Project to TestNG project

   

6. Add TestNG and Selenium as dependency

Implement POM

The Page Object Model (POM) is a design pattern commonly used in Selenium automation to enhance test script maintainability and reusability.

In the POM, each web page is represented as a separate class.

Adding Base Classes

1. Base Page

• We will first create a BasePage class. All page object classes will extend the BasePage, thus inheriting all the base methods.

• Our BasePage class will have a constructor which takes a WebDriver object to initialize a driver object.

  

2. Base Test

• The BaseTest class sets up and tears down the WebDriver using the “@BeforeSuite” and “@AfterSuite” annotations from TestNG.

• The WebDriver is initialized in the ‘beforeSuite’ method and closed in the ‘afterSuite’ method.

  

Adding Page Objects

1. LoginPage

By extending base page in your page object class, you can access these common elements and methods without duplicating code.

2. LoginTest

The LoginTest class extends BaseTest, which means it inherits the setup and teardown methods defined in BaseTest. This ensures that a new WebDriver instance is created before the test and closed afterward.

Configure TestNG

Create a TestNG XML configuration file (e.g., testng.xml) to define your test suite and test classes. You can learn more about TestNG here.

---

Run Tests

Run your tests using the following Maven command.
