Learn how to master, test and simplify your code by using JUnit parameterized tests

In the dynamic world of software development, writing robust and adaptable tests is crucial for ensuring the reliability of your codebase. One of the most powerful features of JUnit 5, the latest version of the popular Java testing framework, is parameterized tests, which allow developers to write more flexible and concise test suites. In this blog post, we’ll dig into the world of JUnit parameterized tests and explore how they enhance test versatility and maintainability.

But first, we’ll go into a brief overview of JUnit 5. It has been developed to leverage new and powerful advances from Java 8 and beyond. It allows the use of multiple extensions simultaneously, which was not possible in previous versions. 

Parameterized tests in JUnit 5: Functionalities

Writing tests for different input values often requires duplicating test methods with varying parameters—an approach that often leads to code duplication and makes tests harder to maintain and more prone to errors. JUnit 5 parameterized tests enable developers to avoid this problem by executing one single test method with diverse parameters. Therefore, we can use JUnit 5 parameterized tests to:

• Simplify test case writing for every possible input
• Reduce code duplication
• Maximize code coverage for all possible scenarios
• Execute tests before deploying builds on the test environment
• Minimize execution time

How to use JUnit 5 parameterized tests

First of all, in order to use parameterized tests, you have to include the junit-jupiter-params dependency.

Custom aggregators:

This functionality allows you to create parameters dynamically or apply custom logic to change the existing values. JUnit 5 allows you to achieve this by implementing a customized ArgumentsAggregator.

class CustomArgumentsAggregator implements ArgumentsAggregator {

    @Override

    public Object aggregateArguments(ArgumentsAccessor accessor, ParameterContext context) {

        return new CustomObject(accessor.getString(0), accessor.getInt(1));

    }

}

@ParameterizedTest

@ArgumentsSource(CustomArgumentsProvider.class)

void testWithCustomAggregator(CustomObject customObject) {

    // Test logic using the custom object

}

Display names

In order to create more legible names for the tests, you can use @DisplayName.. This feature is particularly useful for failed tests, allowing you to read what is going on and what is wrong easily.

Value sources

In JUnit 5, “values sources” is a feature that allows you to provide specific datasets as arguments to the parameters of a parameterized test method. This is useful when you want to run the same test with different datasets.

Instead of manually providing a list of values for the parameters of a parameterized test method, you can use predefined value sources, such as @ValueSource, to specify datasets more conveniently. Other types of sources include @EnumSource, @MethodSource, and @CsvSource.

However, you should take into account that the value sources feature only supports these types:

• short (with the shorts attribute)
• byte (bytes attribute)
• char (chars attribute)
• java.lang.String (strings attribute)
• java.lang.Class (classes attribute)
• int (ints attribute)
• float (floats attribute)
• long (longs attribute)
• double (doubles attribute)
  

Null and empty values

When performing tests, it’s important to validate if the application is going to work correctly when handling null and/or empty values. In order to perform these tests, we can pass a null and empty value using annotations.

Conclusion

Parameterized testing in JUnit 5 is an indispensable tool in the arsenal of any developer committed to software quality. This revolutionary approach saves valuable time by enabling the testing of code with a variety of data without the need to replicate test methods for each scenario. The flexibility and adaptability offered by parameterized testing not only simplify test writing but also improve the maintainability of test code by reducing duplication and unnecessary complexity.

If you are a developer looking to boost your efficiency and explore a wide range of situations and conditions in a single test, parameterized tests in JUnit 5 might be one of your best allies in the landscape of software testing.

• Bias mitigation and ethical AI: Bias and unethical use of LLMs are worrying issues. Strategies are being implemented to reduce biases in language generation and incorporate ethical considerations into the training and deployment of LLM.
  
  
  
• Customization: Currently, LLM use is generic and can lead to ambiguity and lack of context. In the near future, LLMs are expected to allow users to customize their preferences to suit individual choices. To achieve this goal, personalized learning methods are being developed to enhance the user experience and implement mechanisms for continuous learning to keep models up-to-date and relevant.
  
  

• Multilingual competence: LLMs are expected to expand their language support by including and polishing the use of more languages and dialects. This will make the use of LLMs more globally accessible and inclusive.
  
  

• Edge computing integration: Making LLMs more accessible by optimizing them for deployment on edge devices will reduce the dependency on cloud-based solutions and result in increased privacy and efficiency.
  
  
  
• Collaboration with other AI models: Integration with other AIs can enhance functionality and achieve a more comprehensive problem-solving technique.
  
  
  
• Robustness and security: By improving their robustness against adversarial attacks and misinformation and implementing security measures, LLMs can be better protected against potential malicious uses of the technology.
  

•  
• Training methods: Developing more efficient training methods and model architectures will improve the performance of LLMs. Some of these methods include combining multiple models (ensemble learning); conducting systematic hyperparameter tuning to optimize the learning rate, batch size, and other parameters; and including different optimization algorithms to find the most suitable model for each specific task. Also, the incorporation of few-shot and zero-shot learning, which include training a model using few or null examples of a particular task, will broaden the applications for LLMs. (Currently, GPT-3 is capable of few-shot learning.)
  
  

Conclusion

The evolution of LLMs is not static—it’s a dynamic process marked by continual refinement and exploration. The impact of LLMs extends beyond mere language understanding and serves as a catalyst for a more interconnected and intelligent future. And this journey has just begun—the potential for discovery and innovation is boundless. With responsible development, ethical deployment, and continued research, LLMs are going to shape the way we interact with information, each other, and the world at large.

Furthermore, the acquisition of AI programming skills is not only advantageous but essential for developers to contribute meaningfully to the future of technology. A deep understanding of AI programming not only enables developers to navigate the diverse dimensions of AI technology responsibly but also preserves the human touch and critical thinking vital for responsible AI development.

An advanced bash scripting guide to learn how to master functions and libraries to ensure code reusability and organization

Bash scripting is a powerful skill that allows system administrators and developers to automate tasks, streamline workflows, and enhance productivity. While an understanding of basic bash scripting is essential, mastering advanced concepts like functions and libraries takes your scripting abilities to a whole new level. In this blog post, we’ll explore the complexity of advanced bash scripting, focusing on functions and libraries.

Functions: The building blocks of bash scripts

If you’re a developer using advanced bash scripting, you probably know how tedious it can be to copy and paste chunks of code fragments over and over again. Bash functions are blocks of code that you can create and reuse in scripts any time you want. These reusable blocks of code enable you to modularize your scripts and enhance code maintainability. 

A bash function encapsulates a set of commands and can accept parameters, making it flexible and versatile. Here’s a breakdown of key aspects when working with functions:

• Function declaration: In bash, declaring a function is straightforward. It can be declared like this:
  functionName {
  }
  or like this
  functionName() {
  }

• Function invocation: Once a function is defined, you can call it by its name

• Function parameters: Functions can accept parameters, enhancing their flexibility

Libraries: Code reusability and organization

As advanced bash scripting becomes more complex, maintaining a clean and organized codebase becomes crucial. Libraries, in the context of bash scripting, are collections of the functions we have previously mentioned and variables grouped together to address specific tasks. Creating and utilizing libraries can significantly improve code reusability and maintainability, and they allow you to organize your code into modular components.

There are some practices you can follow to maintain a clear organization of your bash scripting:

• Library structure: A bash library typically consists of functions and variables organized logically. To create a library, save your functions in a separate file (e.g., mylibrary.sh) and then include it in your main script using the source command. Consider creating separate libraries for different purposes.
  
  
• Function naming: Be cautious about function-naming conflicts. Prefixing functions in the library with a unique identifier can help avoid clashes with other functions.
  
  
• Sourcing: Use the source or command to include the library in your main script. This ensures that the functions in the library are available in the current script’s context.
  
  
• Variable scope: Variables declared in the library will have the same scope as if they were declared in the main script. Use local inside functions to limit the scope.

5 bash scripting best practices

Best practices are essential, but for various reasons, they might end up being neglected. Here are 5 best practices that you should always apply in bash scripting:

• Comment the code

This is pretty basic but many developers forget to do it, and it’s very useful not only for yourself but for other developers that might want to check or modify your script. It also helps in understanding the role of the function—a very handy feature when you are working in remote environments.

• Use functions

Functions, a set of commands grouped together to perform a specific task that helps modulate the workflow, make the code cleaner, more readable, and easier to maintain.

• Employ double quotation marks

The use of double quotation marks will help eliminate unnecessary word wrapping, word splitting, and whitespace when variable values contain a separator character or whitespace.

• Declare variables

You should always declare the variable according to its data type and use. Variables can be declared globally or locally in the script. When the variable is not declared, bash may not be able to execute the related command. 

• Finish execution error

When executing a script, there may be an execution error. Even if a command fails to execute, the script may continue to run and affect the other commands in the script. To avoid further logical errors, you should always include ‘set -e’ to terminate the command in case of an error.

 

The art of mastering bash scripting

Bash scripting streamlines repetitive tasks, automates processes, and facilitates file and system management, which makes it an indispensable tool for operational efficiency. Thus, mastering Bash scripting can be extremely helpful. Making proper use of functions and organizing them into libraries in bash scripting will allow you to write code that’s cleaner, more modular, and easier to maintain. Not only will you enhance code reusability and reduce the risk of errors, but you will also improve your overall scripting capacity.
