This framework, which gets its name from the acronym for "Next Generation," does a great job of demonstrating its robustness through testing. Here, too, the testing procedure is not too complicated. We may test the scenarios by requesting that the databases or possibly the front ends be tested via the framework. Additionally, an HTML report that is helpful for the tests being conducted can be extracted.

 

Advantages:  

• Assistance with parallel testing
• Facilitates the creation of logs
• Able to provide HTML reports that have been post-tested
• Test cases that underpin them can be grouped together.
• One can define a priority for test case execution.

 

Cons:

• TestNG setup requires extra time.
• If you don't need to prioritize the test cases, it is not advised.

 

• The Cucumber

Cucumber is a Ruby-based testing framework that has gained popularity among testers due to its ability to combine documentation and specs into a single report document. Additionally, the standard is automatically updated.

 

Advantages:

• Improved readable
• Supports step reusability, which lessens the need to repeatedly write the same code
• Some sample tables can be used to automate the tests.

 

Cons:

• Cucumber and gherkin together heighten the intricacy.
• When writing code, testers, and developers concentrate more on creating reusable codes for situations when a straightforward generic code would suffice.

Advantages:

• Provides excellent documentation to assist users.
• Facilitates HTML reporting post-testing
• Effective and simple to use
• JUnit support right out of the box

 

Cons:

• Only stories are supported; no support for features.

 

• Mockito

Mockito is an open-source behavior-driven testing framework built on top of Java. This framework's primary feature is the auto-creation of mock objects, which eliminates the requirement for explicit creation.

 

Advantages:

• Assistance with exclusions
• Annotations can be used to generate mocks.
• Fundamental justification for the return values
• It is not necessary to manually write mock objects.

 

Cons:

• Mocking of local variables is not supported
• Inability to support static and private methods
• There is no control over the private fields for any subclass we write.

5 Common Mistakes Java Developers Make

There may be times when learning a new programming language that you run into trouble. This eventually causes minor-to-major mistakes in Java developers and puts a stop to their learning curve. Remember that even if you'll make mistakes, you'll still succeed in being the best. In addition, learning Java is similar to learning anything else, so it can be mastered with time and the appropriate tools (books, courses, tutorials, etc.). However, the road to becoming an expert is not as easy as it seems; you must make sure you're avoiding all of the "Basic" mistakes that the majority of developers make when they're just "Beginner" level.

 

• Insufficient Understanding of Open Source Libraries

Java developers always make the costly mistake of having half the information necessary. Making mistakes can result from a lack of familiarity with the library they are trying to integrate. There are a wide range of libraries available for use within the code when dealing with Java.

 

• Knowing the "Logic" of Code Is All That's Required

It is almost impossible to memorize every code word in any programming language. Assuming you have committed certain Java grammar and other aspects to memory, you will likely encounter greater difficulty applying them to practical tasks. The more implementation you do, the more complexity you'll be able to handle on any real-life project

• Have an "Action Plan" at All Times

Any project you embark on must have an action plan in place before you can begin working on it. To be a good Java developer, you need to have a clear plan of action. Even your stakeholders may question you about how you handle execution, whether it be design, task allocation, or completing assigned tasks on time.

•  LinkedList vs. ArrayList

This is easy to achieve because ArrayLists are more commonly used and understood. However, LinkedLists frequently perform better than ArrayLists and vice versa. Given the necessity, both are amazingly successful. Generally speaking, array lists work better when an application needs to store and retrieve data. Linked Lists are preferred when an application needs to modify the data that has been stored.

 

• Refuse to Allow “Memory Leakage”

When you begin working with the Java programming language, you will discover that it has a special feature that allows memory to be managed automatically. However, this feature's drawback is related to this. It is important to note that automatic memory management does not preclude human memory checks.
