Selenium/TestNG/JUnit Migration to Katalon Studio

Career growth poll
Do you think IIT Guwahati certified course can help you in your career?

Introduction

Testing is a process which tells us how efficient our app is. We generally test our apps on Selenium or TestNG. Although we have various new platforms with various essential features. Katalon Studio is better than other testing tools because of its ease of deployment and larger integration set.

selenium/testng/junit migration to katalon studio

This article will briefly discuss Selenium/TestNG/JUnit migration to Katalon Studio. We will discuss java class files, installing plugins, discuss the type of keywords in these plugins and the steps to migrate our project from Selenium/TestNG/JUnit to Katalon Studio with ease. 

Java Class Files

During testing, we mainly deal with Java class files. It is widely used because it can easily be made, viewed and edited. 

How to create a Java Class File?

In the Tests Explorer panel, navigate to the Include > scripts > groovy folder, right-click, and select New > Java Class to create a new Java class file. In the New dialogue, select a package and type the class name.

 

Working with Java Class Files

Java class files contain java bytecode. It has a .class extension init. After successful compilation, a Java compiler converts a .java file into a Java class file.

Following is a sample code for the Java class file:

// Java class files for sample, Ninja and Ninja Test
class Sample
{

}

// Declaring the class
class Ninja
{

}

// Declaring the class
class NinjaTest
{
	public static void main(String[] args)
	{
		System.out.println(" File Structure for Class");
	}
}

Now you know how to work with the Java class files, we should move ahead in our discussion about various keywords and plugins. These plugins and keywords will help us easily migrate our test project to Katalon Studio.

Built-in TestNG/JUnit keywords

Katalon studio facilitates built-in keywords for a smooth migration. To use these keywords, you need to install the plugin first. 

Installing TestNG/JUnit Keywords plugin

You can enable the default keywords in the manual view using the keywords plugin. The Katalon Store is where you can download the plugin.

It would be best if you moved the plugin package because the keywords plugin is a platform plugin .jar file in the <project_name>/Plugins/platform folder.

Go to Katalon Studio and select Reload Plugins after installing the plugin.

Now, you have installed the required plugins. The next thing you need to know is the type of keywords you got here in the Katalon Studio. 

Keywords for TestNG/JUnit

You can run tests using the following three built-in keywords provided by the keywords plugin:

⏩ runTestNGTestClasses

SyntaxrunTestNGTestClasses(List testClasses)

Description: It runs the test classes. It then creates a report in the Running Report folder.

testng test class

 

⏩ runTestNGTestSuites

SyntaxrunTestNGTestSuites(List testSuites)

Description: It runs the test suites. It then creates a report in the Running Report folder.

testng test suites

 

⏩ runJUnitTestClasses

SyntaxrunJUnitTestClasses(List testClasses)

Description: It runs the test suites. It then creates a report in the Running Report folder.

junit test class

Migrating Selenium Project

Most Selenium alternatives waste legacy scripts, but Katalon Studio keeps all of your progress into a single, all-encompassing tool.

We will migrate our test project to Katalon Studio using just three steps,

⭐ Copy-paste your source code into a new project. 

⭐ Now, you must use the keywords discussed above to create a test case. 

⭐ Execute these test cases now. 

Your app is now good to go!

Migrating Selenium/TestNG/JUnit projects to Katalon Studio

migrating project to katalon studio

Just like what we discussed in migrating the Selenium project. We can follow these steps to move our project scripts to a Katalon Studio project:

⭐ The first step is to create a new project in Katalon Studio. To do so, you can go to File New > Project. 

Enter the project info such as name, type, repo, location and description. 

⭐ Now, we have to build the dependency for our project.

  •  To add the Java dependencies for your project, open the .gradle file.
     
  •  Now, navigate to the folder with your project in the Command Prompt or Terminal. Now type gradle katalonCopyDependencies, and wait till the Gradle build is finished.
     
  •  Reopen the project now. It will reload all of your dependencies.
     

⭐ Your Katalon project's Include/scripts/groovy folder should now contain the source code for your project. 

⭐ Other project resources should be copied and pasted into the Include folder of your Katalon project (if any).

⭐ Right-click the Include folder, then select Refresh to reload the project's source code and resources.

⭐ To run TestNG test suites or JUnit test classes, create a test case with TestNG keywords.

⭐ Execute these test cases now.
