If you need more power and customization, go with TestNG. For simplicity and ease, JUnit is your best bet. Both are excellent, so choose based on your project needs!

True Testng is really a user friendly, easy to learn and implement and having some amazing features which can be used in test case designing. Reporting, custom reporting like extent, allure report etc can easily be used with Testng.

In report generation with TestNG, the commonly chosen reporting tool is Extent Report, leveraging ISuiteListener and ITestListener.

TestNG is widely used java automation project because of its assertion library, easy to integrate with different reporting library and data-driven test capabilities.

I prefer TestNG over JUnit for automated software testing due to its advanced features: 1. Flexible Test Configuration: TestNG's data-driven testing and dependency configurations offer greater control over how tests are executed. 2. Parallel Execution: TestNG natively supports running tests in parallel, significantly reducing execution time for large test suites. 3. Detailed Reporting: Out-of-the-box, TestNG provides comprehensive HTML reports, making it easier to analyze and debug test results.

TestNG's flexibility in defining test workflows with dependencies and groups is particularly useful in complex projects where test cases need to be executed in a specific order or categorized for better management. Its support for a variety of testing types and enhanced reporting features make it a robust choice for comprehensive test coverage, especially in integration and functional testing scenarios. As an SDET, I've found these capabilities invaluable for ensuring high-quality software in a fast-paced development environment.

The choice is based on requirement, where JUnit is neither less of anything where it's been a key tool for developers to perform the testing!!

True, after junt 5 , junit is easy to implement with less number of lines of code. Features like custom runners, annotations making it very popular among java developers.

Indeed, JUnit has been a classic choice for many Java developers when it comes to unit testing. Its simplicity, ease of use, and robust features have made it a go-to framework for writing and executing unit tests in Java projects. While TestNG offers more advanced features and flexibility, JUnit's straightforward approach and strong community support continue to make it a popular choice.

JUnit has been a preferred option among Java developers for unit testing, thanks to its simplicity, user-friendly nature, and robust features. Despite TestNG providing advanced features and greater flexibility, JUnit's straightforward approach and substantial community backing maintain its popularity for writing and executing unit tests in Java projects.

JUnit 5 enhances Java testing with a streamlined syntax that reduces boilerplate code. It introduces new annotations like @BeforeEach and @ParameterizedTest for easier lifecycle management and data-driven tests. The @ExtendWith model offers flexible custom extensions and runners. Its modular architecture supports component selection and compatibility with JUnit 4. JUnit 5 benefits from strong community support and integration with IDEs and build tools, making it a modern and efficient choice for Java testing.

I would prefer to use Testng with ui and api automation because it is easy to implement. Go with junit for Unit test cases and integration test cases. It's more of a dev centric unit testing framework.

With release of Junit 5 recently, both the frameworks have similar features. Both can do parallel executions, they have near similar annotations etc. My choice would be to go with TestNG since it has been out in the wild for quite some time. Have gotten used to the syntaxes, annotations, configurations. It has proven support from tools like Maven, Gradle and has great community support.

With the recent release of JUnit 5, both frameworks share comparable features. They both support parallel executions and employ similar annotations. However, my preference leans towards TestNG due to its longer presence in the development landscape. I've become accustomed to its syntax, annotations, and configurations over time. Additionally, TestNG enjoys robust support from build tools like Maven and Gradle, coupled with a strong community backing.

It depends on your requirements. Now one can ask which coding language to choose for selenium Java or Python? We can't answer that, because it depends on the Skill Pool. These types of questions are ambiguous and absurd in reality. Both the tools provide similar features but one can do some specific tasks in an optimised manner. For example if I am using a Cucumber based framework then I would use Junit because it is easy, and keeping your framework simple is important. But If I also want to use listeners and external reporters then I can choose TestNg, because, again it is easy to do the required tasks in this tool. So if you are asked these type questions in an interview then just respond honestly, the interviewer will be impressed ????

Choosing depends on requirements but Here are some factors to consider: Features and Capabilities: TestNG offers more features out of the box. JUnit has a more straightforward approach, focusing on simplicity and ease of use. Community and Support: JUnit has been around longer and has a larger community. TestNG also has a supportive community but might have fewer resources in comparison. Integration: TestNG integrates well with tools like Selenium, Maven, and Jenkins. JUnit also has good integration with popular tools and frameworks. Ease of Use: JUnit is known for its simplicity and ease of use. TestNG, while more feature-rich, might have a steeper learning curve. Project Requirements: Consider the requirements of your project.
