In the intricate world of software engineering, the creation and implementation of a test plan stand as a cornerstone of project success. Test plans, detailed documents outlining the strategy, objectives, schedule, and necessary resources for software testing, play a pivotal role in ensuring that a software product not only meets its intended specifications but also delivers a reliable and functional experience to users.

What is a Test Plan?

At its core, a test plan is a blueprint for the testing process. It begins with a skeletal structure at the project’s inception, fleshing out with details as the project progresses. This dynamic document covers everything from the scope of testing and available resources to the specific methodologies that will be employed to assess each feature of the software product.

Types of Test Plans

Understanding the different types of test plans is crucial:

1. Master Test Plan: This document offers a comprehensive overview of the testing approach across different test levels, providing insights into the testing efforts and strategies to be employed throughout the project.
2. Test Phase Plan: Focused on specific test levels or types, these plans delve into the details not covered in the master test plan, outlining schedules, benchmarks, and necessary activities for each phase.
3. Specific Test Plans: These are dedicated to specific types of testing, such as performance or security, focusing on the unique requirements and methodologies applicable to these areas.

Objectives and Importance of a Test Plan

A well-crafted test plan serves several key objectives:

• It outlines the start and end points of the testing process, detailing the resources needed.
• It acts as a roadmap, specifying detailed tasks and guiding the project through its phases.
• It anticipates challenges, offering solutions and organizing stakeholder interactions effectively.

Moreover, a test plan is crucial for facilitating communication within the team and with stakeholders, helping manage changes and ensuring that testing remains aligned with project requirements.

Key Components of a Test Plan

A robust test plan includes several essential components:

• Resource Allocation: Who will test what?
• Training Needs: Identifying skill gaps and training requirements.
• Scheduling: Planning milestones and task durations.
• Tools: Listing software and tools for testing and reporting.
• Risk Management: Identifying potential risks and mitigation strategies.
• Approach: Detailing the testing strategy and scope.

Crafting an Effective Test Plan

Creating an effective test plan involves several steps, from defining the document’s identifier and introduction to outlining the test items, features to be tested, and the testing approach. It also includes planning for staffing, scheduling, risk management, and detailing the deliverables that stakeholders can expect.

In the evolving landscape of software development, the importance of a comprehensive test plan cannot be overstated. It not only ensures the functionality and reliability of the software but also streamlines the development process, making it more efficient and effective. By adhering to a well-thought-out test plan, software engineering teams can navigate the complexities of project development, mitigate risks, and achieve their goals with precision.

Test Driven Development (TDD)

Test driven development is a form of testing done in software development that focuses on creating unit tests before the actual code. Developers create small test cases for every feature with the intention of modifying the code only when the tests fail. Test driven development is also a practice that focuses on the structure of the code that allows for the creation of optimized code that remains reliable over time.

TDD vs Traditional Testing

As stated above, one of the main differences between TDD and traditional testing is that tests are created before the actual code unlike traditional. However some other differences include the testing scope and the processes that each form of testing follows. The testing scope in TDD focuses on testing small, individual pieces of the codebase whereas traditional testing tests the entire system including integration testing. The process of each type of testing also differs in that TDD is an iterative process. As tests are created, this process also includes cycles of developing small chunks of code, testing that code, then refining until all tests pass. An important part of the TDD process is refactoring. Once tests pass, it’s important to check the code if there are any optimizations that can be made, or if there is any redundancy that should be removed.

Benefits to TDD

Test driven development allows for the creation of optimized code by nature because of the process that TDD follows. Once code is written, if the tests fails then the developer is forced to go back and fix the code until the tests pass. The test coverage that TDD covers is greater than traditional testing methods. This is because before any code is written for a specific functionality, the test is created beforehand which ensures every function passes testing. Using test driven development also helps in reducing the number of larger, more complex issues that arise. This is because testing is done on a consistent basis, where development does not progress until each set of tests are complete.

Conclusion

I chose this article because it clearly explained what test driven development is, differences between traditional and test driven development, and the benefits. I also appreciated the use of examples the article used to further explain what the TDD approach would look like in real scenarios. Learning about different approaches to developing software is helpful because I am exposed to approaches that could be more useful than what I already know. I plan to try test driven development in the future.

Last class, we got some hands-on experience with using Test Driven Development. These concepts always feel more concrete and understandable when actually working with them  yourself, rather than only reading articles or looking at examples. I’ve since gotten the hang of this method of development, and wanted to look into how it compares with other development strategies. Such is how I found Test Driven Development is the best thing that has happened to software design by Arek Torczuk.

Throughout the entire article, Torczuk compares the methodologies of code-driven tests and test-driven code. In other words, he judges whether code-first test later is better than test-now code later, respectively. The results for this vary, of course; some companies or teams may benefit more from one strategy than the other. A noted flaw of code-driven testing is that your tests do not challenge the implementation and design of your code. You can create all the tests you’d like on a specific method, but nothing would make you second-guess the way you wrote the method. 

This is where the test-driven approach would come into play. Having already written the tests, you have a better idea of what your code should look like, and how it should act. As Torczuk states, you can ask yourself “What do I expect from the code?” with writing tests before the method (Torczuk). Essentially, with TDD, you know all the answers to your questions and when enough is enough in terms of tests & code. In my mind, it makes the process more streamlined.

Another important part of TDD Torczuk mentions is that it gives quick feedback about the design of your software. You’ll sooner realize the potential issues with your existing codebase, and how it might affect your ability to add new functionality. 

I selected this article because test-driven development piqued my interest after I had more time to experiment with it. This article grabbed my attention specifically because it didn’t just reiterate the concept of Test Driven Development over and over. Another quite useful part of this article is its inclusion of real examples of TDD by the author.

The content of this article was clear cut and organized, and even though it may not have been a ton of new information, it was a different perspective comparing test-driven development and code-driven tests. I learned that generally TDD is more effective at producing well-implemented code than simply writing the method first and tests later. Seeing as we are continuing to learn TDD, I’m confident that I’ll be able to use this in my future projects/jobs if necessary. Or, I could suggest it to my team if we are struggling with writing tests after code.

For this week, I wanted to talk about the creation of comic books, and how it relates to Software Process Management and Software Design. Within the article linked below, it describes the process of how a comic is created, and the steps needed to reach a final project. I specifically wanted to look more into this as the process is quite similar to how software is developed.

The second step is writing a plot, which is much like creating a backlog for your process, planning the beginning, middle and end of the process.

Then, its off to creating the art, which is a multi-step process, which is much like creating the code. For the artists, they need to sketch, then line, then ink and even maybe color the panels of the comic, which parallels how code will need a framework, then main code, supplemental code, and comments to build on top of each other. This process isn’t always in a predetermined order, and can vary from project to project.

And then theres editing and review. Everyone looks over the draft of the work they’ve made, and then tweaks whatever needs adjustments as needed. This process might lead to the recreation of art or code, depending on which process we’re discussing. Once a review gets a pass, they’re ready to finalize and move onto the last step, which is…

Publishing and marketing! Once you’re done, you send the finished copy of the work to consumers to receive, and perhaps you’ll even advertise it, if its not well-known. This can include things like advertisements, sponsorships, and even word of mouth.

The parallels of the dynamics in which these processes interest me a ton as someone whos also minoring in art, and wants to go into a digital design or digital-art focused field, whether it be game design or webcomics. It’s kinda awesome to see that theres a sort of venn diagram between my two passions, and that they can intersect.

EDIT: I meant to post this earlier before, but I had connectivity issues and it never posted when I thought it did. I only realized because a friend wanted to read my blog, haha. To clarify, this blog is intended for Week-12, and for both classes, not 13, it just was posted late due to issues. My apologies for this inconvenience.

Now I know what everyone is thinking, ‘You lied in your last blog.’ Yes, I did, and guess what? This is my blog, so that’s okay. You see, I could not pass up on this beautiful opportunity to kill two birds with one stone. As you may remember from my last blog, I complained about how hard it was to come up with topic ideas for CS-343. Well, well, if by some miracle I read that if topics intertwine between your two classes (343/348), we could count one blog for both classes (shoutout Prof Wurst :)).

Enough yapping, clean code time. I believe it was only a year ago when I first started taking coding seriously, and I can recall how awful my code looked. It worked… but if you wanted to debug, you had to pray before opening it. We are talking about one-function programs, with no formatting and variable names that would drive any professor mad. I quickly realized how important clean code was after watching some YouTube videos and seeing how much easier debugging was if your code had a good flow and was properly formatted. This is where I stopped when it came to clean code, unknowing that there were 100+ other factors that all combine to make clean code.

While exploring LinkedIn, I came across this article by Oleabhiele Donald titled ‘Benefits of Clean Code In Your Application Development.’ I gave this a full read and was really surprised about all the little ways I could make my code even better than it already was. Now I 1000% recommend giving it a full read, but I’m going to talk about some of the techniques that were mentioned that I didn’t know at the time or found most beneficial to me.

Use comments sparingly:

• Limit the use of comments to when necessary, ensuring clarity and conciseness. Overusing comments can clutter the code, making it harder to read. Aim for clear and concise comments that add value.

Write small, focused methods:

• Break down larger methods into smaller, focused ones, each with a single responsibility. This approach improves code understanding and facilitates easier modification.

Use unit testing:

• Incorporate unit testing practices to verify code functionality and prevent the introduction of errors. Well-designed unit tests contribute to clean and reliable code.

Avoid duplication:

• Identify and eliminate code duplication by utilizing methods, classes, and inheritance. Reducing duplication enhances code maintainability and modifiability.

These techniques stood out to me mostly because they were things I just didn’t think about. I love to keep a list on my desktop notepad that always reminds me of some of the key steps to clean code.

Why Clean Code? This a very simple answer thanks to the article, clean code is important enhances readability, making it easier for developers to understand, maintain, and collaborate on software projects. It also improves efficiency, scalability, and reduces the likelihood of introducing bugs, ultimately leading to more reliable software and a happier programmer.

SOLID is an acronym that stands for the 5 different principles that help write high-quality, maintainable, and scalable code. These include Single Responsibility Principle (SRP), Open-Closed Principle (OCP), Liskov Substitution Principle (LSP), Interface Segregation Principle (ISP) and Dependency Inversion Principle (DIP). Each provides their own benefits and work in tandem together when designing a program.

SRP states that a class should only have one responsibility, meaning only one reason to change. This helps prevent a class from having too many responsibilities that can affect each other when one is changed. Following SRP ensures that the code will be easier to comprehend and prone to fewer errors. However, it is harder than it sounds to fulfill this principle. The quickest solution to adding a new method or functionality would be to add it to existing code, but this could lead to trouble down the road when trying to maintain the code.

OCP states that software classes, modules, functions, etc. should be open for extension but closed for modification. This is essential because it allows entities to be extended without modification so that developers can add new functionality without risking the chance of breaking the code. Adding an additional level of abstraction with the use of interfaces help design the program to provide loose coupling.

LSP states that any instance of a derived class should be substitutable for an instance of its base class without affecting the program in a harmful way. The importance of this principle revolves around the ability to ensure the behavior of the program remains consistent and predictable. Unfortunately, there is no easy way to enforce this principle, so the user must add their own test cases for the objects of each subclass to ensure that the code does not significantly change the functionality.

ISP focuses on designing interfaces that are specific to a user’s needs. Instead of creating a large interface that covers all methods, it is more beneficial to split up the methods across smaller, more focused interfaces that are less coupled. For example, having too many methods in an interface can sometimes cause issues in the code, so separating the methods into individual interfaces that can be implemented by a certain class.

DIP states that high-level modules should not depend on lower-level modules but should depend on abstractions. This approach aims to reduce coupling between modules, increase modularity, and make the code easier to maintain, test, and extend. An important thing to note is that both high-level and low-level modules depend on abstractions. Dependency Inversion utilizes the SOLID principles which in turn leads to a more refined and maintainable code.

This is related to the class subject in many ways because it works as a guideline to write the most convenient code for programmers to maintain. Testing the aforementioned code is a simpler process when abiding to the SOLID principles as well. It also allows for easy scalability, making it essential for large code sets that evolve and become more complex over time.

When I first started coding in AP Computer Science, I found it fun. It was like solving a puzzle, a difficult one at first, but it slowly made sense. One thing I struggled with was clean code. I remember vaguely writing code that was disgustingly dirty, as in unorganized, unreadable to others, and all around messed up. I’m surprised I was able to get something to work in those conditions. I soon realized that clean code would be a game changer, as I would be able to read it clearly, and follow along easily.

Clean code consists of some points, having good and descriptive method and variable names, appropriate spacing between different lines of code, and good sectioning are some examples. Ultimately, these can go further based on context. Some variables may not need overly descriptive names if there’s enough context to imply what it is used for. 

In this blog post, Karolina Tóth interviews Robert C. Martin, or Uncle Bob, on his way of building quality code. The post is fairly lengthy but it has very good tips. Uncle Bob talks about what clean code is, its benefits, how not using clean code can negatively affect you, and many more. One tip he gives is keeping your functions as small as possible, because once they start to get large, the method starts to become confusing. By not writing clean code, you slow everything down. On a team, it’s difficult to work together if someone’s code looks like a 5 year old wrote it. By writing clean code, the team can work effectively and efficiently, ensuring quality code. 

I think this is a good post, Uncle Bob has good information, not only on clean code, but also boosting team morale and how to ease into using clean code. His knowledge in teamwork comes from his own experience and mistakes, which I like. Someone has to make mistakes for others to learn, and fortunately, Uncle Bob has done just that.

Clean code is important, whether you work in a team, or alone. It’s good practice to do so. When I first started, it was sloppy code. But now, I can’t stand seeing unorganized code. Even after we had learned clean code in class, I realized that mine wasn’t exactly perfect either. I liked my variable names to be descriptive, but short, and I made the short part priority because I’m lazy. But after reading this post, I understood that it’s not always good to keep them like that, having overly descriptive names can be beneficial, but when they have to be. I like things to be clean, and orderly, and neat, and whatnot, so I’ll be sure to refer back to this post, and the rest of Uncle Bob’s resources later down the line.

In the dynamic realm of software development, a beacon of practical wisdom guides developers through the maze of endless possibilities: YAGNI, an acronym for “You Ain’t Gonna Need It.” This principle advocates a minimalist approach, urging developers to focus on the essential and resist the allure of unnecessary features that might never see the light of day.

YAGNI encourages a “just-in-time” mindset, directing development efforts exclusively toward existing requirements. The core idea is simple: avoid building features or solutions prematurely. Unnecessary additions can introduce complexity, extend development time, and potentially introduce bugs. By embracing YAGNI, developers keep a sharp focus on immediate goals, prevent over-engineering, and maintain a lean and efficient codebase. This not only enhances the development process but also simplifies debugging and ensures a clean and manageable codebase.

Why This Resource?

This extended version builds upon the insights of my previous blog, providing a deeper exploration of the YAGNI principle. The selected resources, Martin Fowler’s YAGNI and C2 Wiki’s YouArentGonnaNeedIt, stood out as foundational pieces providing deep insights into the YAGNI principle. Martin Fowler, a prominent figure in software development, and the collaborative wisdom of the C2 Wiki community added credibility to the understanding of YAGNI.

Insights and Personal Reflection

Delving into Martin Fowler’s exploration of YAGNI, I found a nuanced perspective on the principle. Fowler emphasized the importance of simplicity and addressed the misconception that YAGNI means avoiding all forms of future-proofing. It struck a chord with my experiences, providing a more refined view of when and how to apply YAGNI.

The C2 Wiki, on the other hand, offered a historical context and a communal understanding of YAGNI. Reading through the anecdotes and shared experiences of developers reinforced the practicality and effectiveness of the principle. It resonated with me on a personal level, as I could relate to the scenarios described by fellow developers.

Application in Future Practice

Armed with a deeper understanding from these resources, I anticipate applying the YAGNI principle judiciously in my future projects. Fowler’s insights clarified the delicate balance between avoiding premature features and wisely preparing for potential future needs. The collective wisdom from the C2 Wiki provided a broader perspective, showcasing the universality of the challenges YAGNI addresses.

Conclusion

This extended exploration, building upon the foundation laid in the previous blog, solidifies my grasp of the YAGNI principle. The combination of Martin Fowler’s authoritative voice and the collective wisdom of the C2 Wiki community has enriched my comprehension. I am confident that this refined understanding will significantly influence my coding practices, contributing to the creation of more efficient, maintainable, and adaptive software solutions.

One of the most important aspects of code is to make sure that others who work on or are reading your code can understand what is happening. In class, we have been discussing clean code and improving readability which is where the correlation comes into play which is what inspired me to read further onto the fine details of what entails good code documentation. The blog post I chose for this week’s post was “Shaping better software: The benefits of effective code documentation” by Anabelle Zaluski. The goal of the post was to discuss the importance of having good code documentation and what qualifies as good code documentation.

The blog post starts off with explaining why code documentation is very important as it is like a map for your code. Good code documentation is what allows people to navigate your code effectively and efficiently. According to Zaluski the main information that should be included to qualify as effective code documentation is: “Dos and Don’ts, Clear explanations of each aspect of the application, Illustrative images, including sequence and entity relationship diagrams, and API documentation explaining each class, method, and return value”. She then explained the different types of code documentation as internal, external, low-level, walk through and high-level. With the end of the post explaining the benefits and challenges of implementing good code documentation into your team’s work routine. Some of the benefits included improving team collaboration, supporting maintenance and bug fixing, as well as increasing organizational growth. However, some of the challenges mentioned were staying up to date, managing documentation of non-linear code, and knowing how to document things for various knowledge levels.

I chose this blog post since we have been discussing what clean code is and why we should be using it in our own work. Due to that I thought this blog post was perfect to allow me to connect other ways I should be working to improve the quality of my work. To me this blog post was a very useful lesson reinforcing key points about documentation as well as teaching me aspects that I was unaware of. As we are learning more and more about how to structure our code to improve the quality as well as the efficiency of our team based code. From this blog, I feel like I will be able to implement the strategies and qualities mentioned for good code documentation to improve how I document my work in the future.
