Selenium is an automation testing tool that is used in testing web-based applications. Before you can master Selenium as a software tester, there are some important concepts that you need to master. You can learn these concepts in a simple way by enrolling in a project-based Selenium Certification training

Here are some of them:

1. Java concepts in detail.

Java concepts in detail

Java programming language is a simple programming language that makes writing, compiling, and debugging easy. For you to master Selenium, Java is a programming language you need to understand. Actually, programming languages like Python and C# are also useful in Selenium, but as a beginner, Java is the most important. There are key concepts in Java that you need to understand, some of them include classes, methods, and variable scope, amongst others. You also need to understand how to import statements so that you can make use of the proper methods from the class.

Maven is a concept under Java programming language that you need to understand. Maven is an Apache Software Foundation build tool that is used in automating Java projects.

2. Selenium Automation Framework (SAF).

Selenium Automation Framework is a customized framework developed using Selenium. Selenium Automation Framework increases the efficiency of software automation by limiting the initial coding effort. SAF is a script-less framework used for test automation of web-based applications that are developed using Java / J2EE, .Net, and AJAX. It provides a platform to implement data-driven and Hybrid-keywords added with a data-driven framework by spreadsheet template.

SAF helps ventures speed up software testing using accelerators at the test design layer while also keeping the automation suite adaptable to interface with commercial tools, whenever the need arises.

3. Unit Testing Frameworks.

Unit Testing Frameworks are software tools that support the writing and running of unit tests. It also includes a basis on which to build tests and the functionality to execute the tests and report their results. Unit Test Frameworks are not tools used solely for testing, as they can also be used as development tools by processors and debuggers.

Unit Test Frameworks can impact almost every stage of software development including design and architecture, code implementation and debugging quality assurance, and performance optimization. It is also an important framework to master when using Selenium. Some of the notable Unit Test Frameworks include TestNg for Java, PyTest for Python, and NUNIT for C#.

4. Advanced Reporting.

Advanced Reporting is an open-source reporting framework that is majorly used for test automation. It is an important concept in Selenium because it can be easily integrated with major testing frameworks like PyTest and TestNg. Advanced Reporting also provides highly rich HTML reports that can be in the form of Pie charts. With Advanced reporting, you can generate custom logs and add snapshots. A good example of an advanced reporting framework is Extent Reports.

5. Data-Driven Framework.

A Data-Driven Framework is an important concept in Selenium. It is one of the famous Automation testing frameworks available in the market today. It is a technique used in separating the data set from the code (which is the actual test case). Because the test case is different from the data set, it is easy to modify the test case of a particular functionality without changing the code. Take for instance, if you want to modify the code that is used for login functionality, using this framework will allow you to modify only the login functionality instead of modifying the other features dependent on the same code.

On a usual note, all the test data is placed on Excel sheets which are used for test runs, but Data Driven Framework can be adopted with Selenium to execute the same script with multiple sets of test data.

6. Page Object Model (POM).

The Page Object Model is used in Selenium as a design pattern in test automation. POM creates an Object Repository that can be used for web UI elements. The benefit of using the model is that it limits code duplication and improves test maintenance. When using this model, elements on the page are called variables and web pages are represented as classes. This is to ensure that user interactions can be implemented as methods in the class.

7. Page Factory Framework.

Page Factory Framework is used in Selenium as an inbuilt but optimized Page Object Model framework for Selenium WebDriver. This framework is mainly used for the initialization of Page objects. It can also be used to initialize the Page class elements without having to use the FindElement/s tool.


In conclusion, the concepts above are essential concepts that you need to understand to master Selenium as an automation tool. Learn more about these tools by getting into an online Selenium training.
