TestNG Project Setup in Visual Studio Code Part-1

Updated: Dec 31, 2024

ree

TestNG (Test Next Generation) is a testing framework inspired by JUnit and NUnit with its own functionalities and categories of tests such as unit, functional, end-to-end ,integration etc.


Test Configurations in TestNG allows flexible test configurations such as grouping tests, running tests in parallel, and parameterizing tests. We can validate the test results using Assertions. It is possible to approach Data-Driven Testing in TestNG to run the same test with multiple sets of data. Integration can be done easily with build tools like Maven and Gradle, and CI tools like Jenkins, Bamboo, CircleCI, Git Actions etc.


Test Driven Development (TDD) allows clear communication between developers and testers. Selenium and Java enables automation of web application tests while maintaining a readable code.

VS-Code is a light weight development tool which is easy to learn and use. To create the TestNG framework using VS-Code, we should have a knowledge of VS Code and its Git functionalities. This blog helps in understanding the Selenium TestNG TDD Project which covers the step by step process starting from setting up the repository and pushing the project to GitHub using basic commands and developing in vs code along with basic git commands.


Installing Extensions

VS Code extensions enhances the functionality of the VS Code editor and customizes the workflow and suits the needs of the project for development and test environment. It adds new features, provides language support and integrates with external tools etc.

Click on the extension symbol, start searching for the extensions and click install on the extensions that your project requires. You can see all the installed extensions in your VS-Code as this screenshot depicts.

Creating a Maven Project


  1. We can create a maven project using following command from the PowerShell in windows

    1. Navigate to a folder where you like to create a maven project

    2. Right click on the folder to launch the command prompt or a PowerShell

    3. Execute the following command from the Prompt

    4. Once executed get into the folder using "cd blog-testng-demo" command and execute "Code ." to launch the VS-Code

mvn archetype:generate -DgroupId="com.NumpyNinja" -DartifactId="blog-testng-demo" -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

cd blogTestngBDD
code .

  1. We can also create a maven project using VS-Code

GitHub Copilot/Copilot Chat


As you see, we have installed GitHub Copilot and GitHub Copilot-chat in the VS-Code extensions. GitHub Copilot is a paid service which effectively detects the syntax and code errors and suggests the corrected ones. If you encounter an error in your code, you mouse over on the code, it will suggest you options to choose whether you can make a correction with a suggested explanation or you can just click "fix using copilot" and it will fix your errors but always confirm the solution.


GitHub Copilot Chat is a conversation space where you can raise your queries and get answers. You can also copy your complex codes or scripts and paste it in the chat to get the line by line explanation by reading your given codes.
