Java Inheritance, Java Object-Oriented Programming, Types of Inheritance in Java, single inheritance, multiple inheritances, and ‘extends’ keyword.

24. Java OOPS – Polymorphism

Polymorphism is derived from two Greek words: poly and morphs.

Polymorphism in Java is a concept by which we can perform a single action in different ways.

We have two types of Polymorphism:
1. Compile Time Polymorphism/Method OverLoading
2. Run-Time Polymorphism/Method Overriding

Module 3: Selenium WebDriver

1. Introduction

According to Selenium’s official website ( Selenium automates browsers, Selenium’s primary purpose is Testing of Web Applications, and Selenium is also supported Automating Web-based administration tasks.

Selenium WebDriver is used for Functional & Regression Testing of Web Applications, It supports various Operating systems, programming languages, web browsers, and Testing frameworks.

Selenium WebDriver supports Batch Testing, Data-Driven Testing, Cross Browser Testing, and Database Testing.

2. Selenium Environment Setup

Selenium is not an all-inclusive test tool, it requires third-party frameworks & plugins to broaden the scope of testing. So first choose Selenium Tools and Other Software for Testing.

Example: Eclipse IDE as Editor for writing Test Scripts, Java for Programming, and TestiNG as Test Runner.

Download & Install Java, set Java Environment Variable path, download Eclipse IDE and install, add WebDriver jar file/s to the Java project, and Download TestNG plugin & Install in Eclipse IDE.

3. Web/HTML Elements

Web or HTML Elements, web page, frame, link, button, radio button, checkbox, drop-down box, list box, combo box, image, web table, para, and page headers.

Selenium Element Locators like id, name, className, linkText, partialLinkText, cssSelector, and xpath to recognize the elements during Automated Testing.

4. Locating Web Elements

One of the most fundamental techniques to learn when using WebDriver is how to find elements on the page. WebDriver offers a number of built-in selector types.

An important task in Automated Functional Testing is ‘Locating Elements’ or Object Identification.

Selenium supports eight types of locators to locate/identify/recognize elements in web pages.
(id(), name(), className(), tagName(), linkText(), partialLinkText(), cssselector(), xpath())

5. Actions on Web Elements

Selenium WebDriver Methods, Actions on web elements, Selenium Brower commands, browser navigation commands, and commands on web elements.

Element Locators – Locating/Identifying/Recognizing elements in web pages
Selenium WebDriver methods – To perform actions on web elements

Note: Using Element Locators and WebDriver methods we create Test steps.

6. Handling Web/HTML Elements

Handling Web Elements in Selenium, handle browser, edit box, button, link, checkbox, radio button, image, dropdown box, text, popup window, web/HTML table, web frame, etc,

Pre-requisites to create Test cases in Selenium

1. Web/HTML Elements
2. Element Locators (To recognize/identify Elements)
3. Selenium WebDriver Methods (To perform operations on Elements)

7. Writing Test Cases

Prerequisites for writing Selenium WebDriver Test Cases…

1. Select Manual Test Case for Automation
2. Element Locators to Locate/Recognize/Identify Elements/Objects
3. Selenium WebDriver API Commands to perform operations on elements
4. Programming Concepts to enhance the Test Cases
5. Testing Framework (Junit/TestNG) to group Test cases, prioritize Test cases, execute Test batches and generate Test Reports.

8. Cross Browser Testing

Cross Browser Testing is a type of test to check that our Web Application works as expected in different Browsers.

A web application can be opened in any web browser by the end-user, So we need to ensure that the web application will work as expected in all popular browsers.

Selenium Cross Browser Testing, What is Cross Browser Testing?, Popular Web Browsers, Browser Compatibility Testing using Selenium WebDriver.

9. Data-Driven Testing

Executing a Test case using multiple sets of data is called Data-driven testing. By using any resource (Test Data file) we can conduct Data-driven testing.

Data-driven testing is for conducting Positive and Negative Testing.

Write Selenium Data-Driven Test Case, Inspect HTML Elements, Identify unique locators for Web elements, and perform actions on the web elements using Selenium Webdriver methods.

10. Batch Testing

11. Page Object Model

Page Object Model in Selenium, Create Object Repositories in Selenium, Advantages of Page Object Model, and reuse elements in Selenium Test Cases.

Page Object is a Design Pattern that has become popular in test automation for enhancing test maintenance and reducing code duplication.

Module 4: TestNG for Selenium

We use Testing Framework as Test Runner in Selenium, it is used to prioritize Test cases, Grouping Test cases, Execute Test batches, and generate Test Reports.

1. Install TestNG and write first TestNG Program
2. Create multiple Test cases & Run
3. Execute/Run multiple programs using XML
4. Grouping Test Cases
5. Parallel Testing
6. Data-Driven Testing using @DataProvider annotation
