What Selenium Webdriver and TestNG Really Mean? 

The future of selenium is quite promising as it provides various opportunities for the business. Every organization is striving to offer an excellent experience to its users all the time. They are looking forward to optimizing the look, feel, and performance of their developed apps and selenium testing is perfect for reaching all the goals. Even taking the support of selenium Webdriver and TestNG is just like adding a cherry to the favorite dessert. 

Selenium Webdriver

It is one of the advance web automation frameworks which allows users to execute their tests. They can easily execute tests against different web browsers. Selenium WebDriver facilitates users to use a programming language for creating test scripts that might not be possible while they are using in Selenium IDE. It enables them to use various conditional operations such as switches cases, if-then-else, and many more. 

Selenium Webdriver also allows users to perform looping as per their coding and testing requirements. It provides support for various programming languages like Java, PHP, .Net, Perl, Python, and Ruby. Besides this, users get various benefits when they use Selenium Webdriver, they are: 


  • Help to bagged a higher ROI.
  • Easy access, users can even access it remotely through any device. 
  • Reduction of flaws.
  • It helps to find bugs and flaws at the initial stage.
  • It makes the process more reliable and tests dependable for users.
  • Enables testing in volumes.

TestNG Framework: 

It is an automation testing framework that is widely used by testers to test the developed product. NG is referred to as "Next Generation", this automation testing framework is inspired by JUnit and NUnit, and it uses the annotations (@). It is an open-source test framework for Java. (Source)

TestNG framework's advanced and useful features make it robust and more useful than others. It is portrayed by Cedric Beust and is frequently used by coders and testers for creating a test case for their project. They can easily use their multiple annotations and multiple features. It also offers various benefits to the users who prefer it, some of the benefits are as follows: 

  • Logs generation.
  • Easy use of annotations.  
  • Enables users to group and prioritize test cases. 
  • Allow parallel testing. 
  • Helps to product execution HTML reports.  
  • Data parameterization.

TestNG framework can be integrated with various tools as per users' requirements, users can use tools such as Jenkins, Maven, Jenkins, and many others to test their app. Using Annotations of TestNG framework makes it easy for coders and tester to understand the overall process.

They can use annotations like @BeforeTest, @AfterTest, @BeforeMethod, @AfterMethod, and many others. There is a lack of a native mechanism in Selenium WebDriver, which makes it quite hard for users when it comes to reporting generation. But while using the TestNG framework, users can easily generate the report that also in a readable format, have a look to know how the report actually look: 

TestNG simplifies the way of coding for the tester, they need not need to apply the static main method in their tests. Instead of that, they can simply use a sequence of annotations to perform various actions in the test, users don't require to make the method static, which makes the testing process much easier to understand for the users. Have a look to know how to use annotations instead of the static methods.  

Handling Uncaught exceptions has become much easier with the TestNG framework as it handles it automatically. Testers can handle it without terminating the test prematurely, such exceptions can be termed as failed steps.

Users can even create a group while using TestNG, which lesser their coding comparatively and make their work much more manageable. But while creating the group with TestNG, they have to consider some of the aspects and codes which is listed below.

Syntax For Creating Groups in TestNG:

Syntax

     @Test(groups={"groupname"}) 

Example of implementing single and multiple groups:

After completing the grouping process, users can easily exclude and include testng.xml as per their requirements. 

<include>: Helps testng.xml to know which group actually needs to be executed.

<exclude>: Helps testng.xml to know which group actually needs to be Skip during execution.

Thus if any of the users execute their test cases with grouping, then they have to make changes (modification) to their testng.xml file. They have to explicitly the file after specifying the group to it. View code to create and modify the complete program using group test cases in selenium.

In the above-mentioned XML code, you can explore that a new tag called group is added to it. And under group tag, two different tags exclude and include is mentioned. Users can also mention the group name as per their convenience and requirement and can include and exclude the same in the needed file. 

Selenium Webdriver and TestNG: Explore How You Can Use It Parallelly While Execution

When users have to test the application, then it becomes essential for them to test the particular app on different browsers. If they do not do so, then it becomes difficult for them to know whether the app supports the particular browser or not. Moreover, testers can test their effectiveness with the help of Selenium WebDriver and TestNG. 

If the tester or developer wants to execute numerous scripts, then it becomes quite challenging for them as it is one of the time-consuming tasks. However, if they want to complete it quickly, then they can use Parallel Execution, which is one of the critical concepts of selenium. In this concept, they can use Selenium WebDriver and TestNG partially and can complete the execution process. 

TestNG facilitates users to execute test cases/scripts in parallel. Furthermore, by using the Parallel Execution concept, they can easily reduce the execution time, as all the tests are executed on different browsers at the same time as they have already declared it in the testng.xml file. Explore the below code to know how it can run on multiple browsers at the same time (that is parallel).
