Design Patterns

Design patterns are essential tools for software developers, providing standardized, reusable solutions to common coding challenges. Rather than developing unique solutions every time a familiar problem arises, developers use these templates to write organized, efficient, and adaptable code. Design patterns are not complete blocks of code but instead serve as blueprints, guiding the structure of code in object-oriented programming and enhancing overall project organization.

according to the published article on GeeksForGeeks, the article mentions about A key advantage of design patterns which is reusability. Patterns can be applied across different projects, which saves time and effort by eliminating the need to repeatedly solve similar issues. This flexibility also allows developers to apply patterns quickly in various scenarios, accelerating development. Another benefit is standardization; design patterns create a common vocabulary among developers, which simplifies communication and collaboration within a team. By recognizing these patterns, all team members can quickly understand and follow the structure of the codebase.

Design patterns further promote efficiency by offering solutions that have been tested and refined over time. Since developers do not need to invent new solutions for frequently encountered problems, they can progress faster with fewer errors. Additionally, design patterns are designed to be flexible. They are adaptable templates, meaning they can be customized to fit specific project needs, making them a versatile tool for a variety of applications.

Types of Design Patterns

Design patterns fall into three main categories: Creational, Structural, and Behavioral.

  1. Creational Patterns focus on managing object creation to keep systems flexible and independent of object-specific creation logic. Examples include:
    • Factory Method: Allows creation of objects without specifying the exact class.
    • Singleton: Ensures only one instance of a class exists globally.
    • Builder: Breaks down complex object construction into simpler steps.
  2. Structural Patterns emphasize organizing classes and objects to create efficient, larger structures. Examples include:
    • Adapter: Enables incompatible classes to work together by adjusting their interfaces.
    • Facade: Simplifies complex systems by providing a unified interface.
    • Decorator: Adds extra functionality to objects without altering other instances.
  3. Behavioral Patterns focus on defining how classes and objects interact within a system, streamlining communication in complex applications.

In summary, design patterns help developers produce clear, maintainable, and scalable code. By adopting these patterns, developers can approach recurring problems with reliable solutions, improving collaboration, reducing development time, and creating codebases that are easy to expand and adapt. In the fast-paced world of software development, design patterns serve as a stable foundation for building robust, flexible applications

Behavior Driven Development

Behavior Driven Development ( BDD ) is a test practice that makes sure there is good quality by automating test before or during system behavior specification. BDD test focuses on facing scenarios that describe the behavior of a story, feature, or capability from a user’s perspective. When the tests are automated they make sure that the system constantly meets the required behavior.

The Behavior Driven Development Process

The BDD process has three phases to it. The discovery phase, formulation phase, and the automation phase.

1.) Discover phase: This phase is where the user creates the initial acceptance agenda for the feature. This phase is usually done in a collaborative manor, each team member is contributing.

2.) Formulation phase: This phase is where the acceptance agenda sets into detailed acceptance tests, as the backlog item gets closer to implementation. This phase also incorporates specific examples of the behavior.

3.) Automation phase: This phase is where automation tests are automated to run constantly. This is to make sure that the new system supports the new behavior.

Benefits of Behavior Driven Development

1.) Early detection of errors / defects: When you automate tests in the early stages of development process, you can identify and address the issues. BDD allows for the early detection of defects.

2.) Faster Flow and Time: when using BDD, you can reduce the errors, rework, and replan. BDD accelerates the flow of the development process. Developers can produce features / products faster and more efficiently.

3.) Stronger Test Coverage: BDD allows for a more comprehensive test coverage that focuses on the user behavior and scenarios. Both common and edge cases are tested as well.

4.) Clear understanding: BDD can be plain and clear to understand, because specific scenarios are used to describe the behavior from a user’s point of view. This helps the development to fully understand the requirements and whats going on.

Static Testing vs. Dynamic Testing

Testing in software development is important because it helps to deliver efficient and user friendly products to the end user. It also provides the developers with a chance to improve upon the product. Static and Dynamic testing are two important techniques used in software development.

Static Testing

Static Testing has various names like Verification Testing, Non-execution Testing, etc. This testing technique is used to identify defects in software without actually executing the code. This method usually includes manual and automated evaluation of the software and the code. Developers use this method usually in the beginning stages of the development process to catch issues early on, which will also lead to be easier and cheap to fix. This method focuses on reviewing the test cases, test scripts, test plans, and source code.

Static Testing Techniques

1.) Informal Reviews: Developers review each of the documents and give feedback

2.) Walkthroughs: Someone presents the product to the team and someone else takes notes.

3.) Technical Reviews / Code Reviews: review the technical specifications and the source code to make sure everything meets the requirements and standards.

4.) Inspection: Check for defects. Developers usually review the process with a checklist to help identify and record for defects.

Dynamic Testing

Dynamic Testing is a technique that analyzes the dynamic behavior of the code by actually executing it. This method makes sure to check that the software functions correctly and that there are no underlying issues / conditions. Sometimes developers use this method in conjunction with black box or white box testing to provide more realistic results.

Dynamic Testing Techniques

1.) White Box Testing: Examines the internal code structure. You need to actually have the internal code (source code)

2.) Black Box Testing: Checks the functionality without the actual internal code (source code) .

Benefits of both Static Testing and Dynamic Testing

1.) Early detection of defects

2.) Cost efficient

3.) Showcases runtime errors

4.) Reliability

Week 15

Last week my group and I were discussing behavior-driven development. It is a type of development that refines our previously learned developments. This is a great jumping point to what we were previously learning and it will make for a great assignment. I would like to give more information on this subject matter because it is valuable. This is another practice that is used in the field that can be used in the future.

Behavior Driven Development (BDD) is an agile testing practice that prioritizes creating automated tests first before specifying system behavior. BDD is utilized in a group setting where both agile teams and business participants can see eye to eye. BDD are tests used to capture a story, feature, or capability from a user’s perspective. During this development, there should be three different heads of mentality to considered. Customer minds usually stakeholders understand the business needs and their desire for new requirements. Developers understand what needs to be done to accomplish their responsibilities and technological feasibility. Test-centric minds should consider any exceptions, new edges, and boundary conditions. There are three phases during BDD discovery, formulation, and automation. The product owner or product manager creates criteria that must be used to write a good story. Then, the discovery process where the team finds any additional information that could enhance the criteria. There is an automation phase that automates the acceptance test. This test shares a lot of similarities with Acceptance Test–Driven Development (ATDD) and Specification by Example (SBE). 

This new development strategy was very useful to learn. It’s good to understand different types of development plans and how you can combine them to make a stronger development cycle. During the agile team cycle, I feel like every cycle you can change what type of software development you use for that cycle. Based on the project, resources, and time you can choose different software developments. Learning about BDD gave me an insight into the business side of the development process. These are things you may not think about when creating your software but should be a priority. You would expect your software project to be examined by someone who is informed in the field but to try to explain to someone that is funding it would be a hassle but necessary. It makes sense that people who aren’t on the team would have to understand the development. It’s a group effort between multiple teams that all must work in unison to create a working product.

Week 14

Considering this week we only had one day of class it’s good to reinforce the ideas we learned to spread out in separate classes. I was in a search this week for an article that went into depth about software technical reviews. Software technical reviews are very important; understanding the fundamentals is a key component in the field. 

The main function of a software technical review is to examine a document either in a group or alone and find errors or any defects inside the code. This is done to verify various documents to find if they reach specifications, system design, test plans, and test cases. An important thing to consider is this is a step to make sure the client gets clarity of the project and stays informed on how it’s going. In addition, finalize any changes to reach the requirements before being released to the market. This allows for improved productivity, makes the testing process cost-effective, fewer defects to be found outside the team, and reduces the time it will take to create a technically sound document. The main three types of software reviews include software peer review, software management review, and software audit reviews. The process of software review is simple if you are informed of the implementations taking place. First is the entry evaluation which is just a standard checklist to know the basis for the review. Without a checklist, you will be pulling on strings to find what is wrong with the code or what it’s missing. Then comes Management preparation ensures that your review will have all the required resources like staff, time, and materials. Next is review planning where you create an objective that comes from the team. You then move on to preparation where the reviewers are held responsible for doing their specific task. Lastly, examination and exit evaluation where the group meets up and is discussed to make the team on the same page and verify any discoveries.

Reading this article allowed me to see other steps that are taken to do a software technical review. If we as a team were able to create an objective of what to search for inside the code last week it would have been more goal-oriented instead of randomly searching for faults in the code. As a team, it would have been great to have a more organized group so then when we come together we have an understanding of what we should all find. I would like to see how it would work trying to explain to someone who doesn’t code what has been done and show them that their money is being placed in the right place. Other than that this is a great way to reduce time and be in unison with your team.

“Draw Your Own Map” Individual Apprenticeship Pattern

This week, I decided to focus on the “Draw Your Own Map” Individual Apprenticeship Pattern for CS448-Software Capstone. This is my final required apprenticeship pattern analysis post, and I chose this pattern because it feels applicable to me as I am about to graduate and enter the working environment, mapping out my intended career path from its starting point. 

The “Draw Your Own Map” individual apprenticeship pattern emphasizes the importance of taking control of one’s career development and learning journey. It encourages individuals to proactively chart their own course rather than relying solely on predefined paths or external guidance.

At its core, this pattern advocates for self-directed learning. It urges individuals to actively seek out opportunities to acquire new skills, knowledge, and experiences that align with their career aspirations. Setting personal goals is essential in this process, providing a roadmap for growth and development.

Identifying various learning opportunities, both formal and informal, is crucial for professional advancement. This could include attending workshops, pursuing certifications, participating in projects, or seeking mentorship. Adaptability and flexibility are also key, as career paths may require adaptation and adjustment over time.

Regular reflection on progress is encouraged to refine goals and adjust course as needed. By reflecting on past experiences and learning outcomes, individuals can iterate and improve their development strategies. Additionally, building a personal brand and reputation within the industry is essential for showcasing skills, expertise, and achievements.

In essence, the “Draw Your Own Map” pattern empowers individuals to navigate their professional journey with autonomy, self-reflection, and continuous learning. By embracing ownership of their career trajectories, individuals can pursue their long-term goals with purpose and resilience.

With such a competitive entry-level environment, it is possible that I may find myself (or at a later point in my career) choosing to take a position that may not fully align with my interests and career goals. Additionally, with all of the ongoing changes in the tech industry and world as a whole, what may have been a traditional and common career path is impractical today. So, it’s crucial that I can draw my own map to success and redraw it as necessary throughout my career. By following the strategies outlined in this apprenticeship pattern, it seems a lot more realistic to be able to take a starting position that may be less-than-ideal while still progressing toward my intended goal.

Week 13

The next classes will be about Software technical review it would be great to get a step ahead by delving into the concept. We only started with the review section of the code but fully understood it before the class could skip the barriers of never implementing this idea. Whenever doing something new there is always a barrier which can be difficult at first but with practical knowledge, it can be implemented with a greater effect.  

This article first talks about why there is a technical review. There are technical reviews for the company’s higher-ups who may not be fully aware of the coding process and the difficulties that come with it. They have to understand the developer’s importance to the business because they are spending a lot of money with ineffective results. Many times deliveries aren’t are time and come in fault states having several bugs. This is where a technical review comes in handy it’s a deep dive that provides a suitable perspective. Their definition of a technical review is a deep dive assessment of your software that provides findings and recommendations that be later adapted or discussed amongst your team. Common finds inside a technical review include slow or late deliveries which are just not meeting the due date, random or persistent bugs an example would be fixing the same thing over and over again, and sleepless nights because of worrying too much. These aren’t the end be it all every technical review is different and should be focussed on your team’s goals. The main discussion should be of pain points the things that keep you up at night to make the software complete. Process and team review is another key ingredient that makes sure everyone is working on the right task or if there are changes that need to be made plus an idea to every team member’s contribution to the project. The last thing the team should do is an effective summary that can be graded with a brief description. Detailed findings and recommendations that can be read by people not in depth with coding so they can get an idea of what is being done behind the scenes and can tell the team what needs to change.

Reading this article gave me an idea as to why we do technical reviews because when doing mine I was stuck trying to figure out problems in the code. I didn’t want to nitpick and find small issues that would seem redundant because at times it is better to keep it clean and simple. But understanding that this needs to be done to prove to people on the other side of the business that work is being done is a great insight. It makes a lot of sense that other people in a company would want to know what is happening on other sides of the department.
