The “Breakable Toys” pattern offers a solution to a common problem faced by software developers, which is the lack of opportunities to learn from failure in a professional setting. The purpose of this pattern is to create a safe environment where developers can experiment, make mistakes, and learn without fear of repercussions. By building toy systems that mimic real-world settings but with reduced scope and complexity, developers can gain valuable experience and develop their skills more effectively.

The intriguing thing about this pattern is its emphasis on the importance of failure in the learning process. In many industries, including software development, there’s often a stigma attached to failure, which leads to a culture where taking risks is discouraged. However, this pattern changes that mindset by suggesting that failure is not only acceptable but also a necessary step toward growth and improvement.

As someone whose goal is to become a software developer, this pattern has certainly changed my perspective on my approach toward learning and skill development. It highlights the value of creating a learning environment that prioritizes experimentation and iteration over perfection. This helps get rid of the fear of failing and being afraid to make mistakes, and now I see them more as opportunities to grow and learn.

One of the aspects of the pattern that resonates with me is the idea of “budgeting for failure”. By allocating time and resources to build and experiment with breakable toys, developers can proactively invest in their own professional development. This proactive approach to learning is essential in this industry due to the continued growth and evolution, where adaptability and continuous improvement are key to success.

While I do like this style of thinking, I can also see potential challenges in implementing this pattern in a corporate environment that may prioritize productivity and efficiency over learning and experimentation. Convincing management or team leaders of the benefits of breakable toys may require a shift in mindset and a willingness to embrace a culture of learning and innovation.

Overall, the Breakable Toys pattern offers a refreshing perspective on how to approach learning and skill development in software development. By creating a safe space for experimentation and failure, developers can cultivate a growth mindset and become more resilient and adaptable in the face of challenges.

In this week’s blog post, I will be discussing the “Expose Your Ignorance” pattern discussed in chapter 2 of “Apprenticeship Patterns: Guidance for the Aspiring Software Craftsman” by Dave Hoover and Adewale Oshineye. This week, I chose this topic for my blog post because I think being able to show that you don’t know everything and can have confidence in learning is essential to growth, both professionally and personally.

This section of the chapter discusses that learning is an essential part of the development process. “Show the people who are depending on you that the learning process is part of delivering software. Let them see you grow. According to research by the social psychologist Carol Dweck, the need to appear competent is ingrained into people of most industrialized societies. These societies are increasingly dependent on your competence as a developer, as software creeps ever-deeper into our everyday lives. Yet because of your inexperience, you have many zones of ignorance. You are in a bind. The people around you—your manager, your client, your colleagues, not to mention yourself—are all under tremendous pressure to deliver software. You can see the need for confidence in people’s eyes when they ask you how long feature X will take you to finish. There can be tremendous pressure to pacify them, to reassure them that you know precisely what they want, how you’re going to give it to them, and when.” The need to appear completely in control and competent when you are new is a very difficult instinct to let go of, but it is essential to free yourself of it if you want to progress.

You must be honest with your colleagues and clients, don’ just tell them what they want to hear because what they want to happen might be impossible. “Software craftsmen build their reputations through strong relationships with their clients and colleagues. Conceding to unspoken pressures and telling people what they want to hear is not a good way to build strong relationships. Tell people the truth. Let them know that you’re starting to understand what they want and you’re in the process of learning how to give it to them. If you reassure them, reassure them with your ability to learn, not by pretending to know something you don’t. In this way, your reputation will be built upon your learning ability rather than what you already know.”

In this week’s blog post, I will be discussing the “Concrete Skills” pattern discussed in chapter 2 of “Apprenticeship Patterns: Guidance for the Aspiring Software Craftsman” by Dave Hoover and Adewale Oshineye. This week, I chose this topic for my blog post because I think being able to supplement your knowledge with practical abilities will show to future development teams that you can be a helpful addition to the teams.

The first part of this section talks about how some of the first concrete skills that you will learn will mostly entail navigating HR and team assignments, and being able to assure your team mates that you won’t need constant supervision. “Acquire and maintain concrete skills. Even though one of the things that an apprentice brings to a team is an ability to learn quickly, the possession of discrete and demonstrable ability with specific tools and technologies increases the likelihood that you will be trusted to contribute indirectly until you start to gain stature. Some of the concrete skills you should acquire will be little more than mechanisms to get you past crude HR filters and managers who construct teams by playing buzzword bingo. Others will reassure your prospective team members that you can be put to good use and will not require “day care” (Organizational Patterns of Agile Software Development, p. 88). Examples of concrete skills include writing build files in various popular languages, knowledge of various popular open source frameworks like Hibernate and Struts, basic web design, JavaScript, and the standard libraries in your language of choice.” Being able to show your fellow developers that you can stand on your own with development is a very important aspect of joining new development teams, but you must be able and willing to ask for help when you need it. The next section mentions something briefly that I think is incredible important, being able to quickly and effectively show an interviewer your concrete skills.

Being able to quickly and succinctly describe your concrete skills in a technical interview is essential. “The point is that you will often require hiring managers to take a leap of faith in choosing you. Concrete skills (which are ideally discrete enough that you can bring toy implementations to an interview) allow you to meet them halfway. The concrete skills you possess are your answer to the question: “If we hire you today, what can you do on Monday morning that will benefit us?” A deep understanding of Your First Language will help establish your credibility and should prove to be extremely useful to your team.”

In this week’s blog post, I will be discussing the “Unleash Your Enthusiasm” pattern discussed in chapter 2 of “Apprenticeship Patterns: Guidance for the Aspiring Software Craftsman” by Dave Hoover and Adewale Oshineye. This week, I chose this topic for my blog post because I think being able to properly and effectively hone your energy to be the most productive is an important skill.

The article first discusses how a new hire’s enthusiasm can be unintentionally forced down by the new hire in order to try to fit in with the development team. “Despite (and because of!) your inexperience, you bring some unique attributes to your team, including an infectious enthusiasm. Do not allow anyone to dampen your excitement for the craft—it is a precious commodity and will accelerate your learning. As a software developer, you will inevitably work as part of a team. In any group setting, there is a tendency to conform to the norm, particularly for newcomers. Most teams are not hyper-passionate or overly enthusiastic about technology. Predictably, they are focused on delivering the next project or improving on the aspects of the development life cycle that are causing them pain. Therefore, enthusiastic apprentices can often succumb to the urge to fly under the radar. They either repress their enthusiasm altogether, or allow it to manifest only outside of their day jobs.” While this is a natural reaction, it is important to be able to know when to show some of this passion to your team because, your passion is infectuous and may be able to help with team morale.

You must be careful however, depending on the team showing too much passion may work against you. “There are certainly risks involved in unleashing your enthusiasm on an established team. If morale is low or if the team is not welcoming of newcomers, you will likely get some eye-rolling behind your back. You could certainly make a poor impression on people who value competence more than learning ability, particularly when you expose your ignorance. Like any pattern, this one should not be applied blindly. Team dynamics should always be considered. If you find yourself on a team that does not accept your excitement, you will need to find ways to nurture your passion. “

What is Software Testing?

Software testing is the process of evaluating whether a program or application functions as intended. It serves as a form of quality control, aimed at identifying and rectifying any discrepancies or errors before production use. For instance, in the scenario of a budget-tracking app, testers would verify the accuracy of data input, functionality of buttons, and ease of navigation, among other aspects, to ensure a seamless user experience.

Levels of Testing

Testing levels, also referred to as levels of testing, encompass distinct phases or stages of assessing software throughout its development cycle. These levels target specific aspects of functionality, contributing to enhanced quality assurance and reduced defects. The primary testing levels include:

1. Unit Testing: This level involves testing individual components, such as methods and functions, in isolation to ensure their correctness and functionality. Automated unit testing is often recommended, allowing for efficient evaluation of code behavior. Unit testing is crucial for identifying bugs at an early stage of development, as it allows developers to test each component independently. By writing automated tests that cover various scenarios, developers can ensure that their code performs as expected.
2. Integration Testing: Integration testing assesses the interaction and integration between various units or modules within the software. It aims to detect any issues arising from coding errors or integration conflicts, facilitating seamless collaboration between components.During integration testing, developers test how different modules work together to ensure that they function properly as a whole. This ensures that any errors or inconsistencies between modules are detected and addressed before moving to the next stage of development.
3. System Testing: System testing evaluates the integrated system as a whole, verifying its compliance with specified business requirements. Automation tools can be leveraged to streamline system testing processes, ensuring comprehensive assessment of functional and non-functional aspects.System testing focuses on evaluating the entire software system against the defined requirements and specifications. It includes testing functionalities, performance, security, and compatibility to ensure that the software meets the desired standards.
4. Acceptance Testing: Acceptance testing focuses on validating the system’s functionality and performance against user-defined criteria. It encompasses aspects such as usability, security, compatibility, and reliability, either through manual evaluation or automation tools.Acceptance testing involves end-users or stakeholders testing the software to ensure that it meets their expectations and requirements. This stage ensures that the software is ready for deployment and use in a real-world environment.

Software Testing Sequence

A structured testing sequence is essential for thorough evaluation of software functionality. This sequence comprises four main stages:

1. Unit Testing: Testing individual components to ensure functionality.
2. Integration Testing: Evaluating interactions between integrated units.
3. System Testing: Assessing the integrated system as a whole.
4. Acceptance Testing: Validating the system against user-defined criteria.

Conclusion

Software testing is a critical process in the software development lifecycle. It serves as a safeguard against defects and ensures that software meets user expectations and business requirements. Skipping or neglecting testing can have detrimental consequences, undermining the utility and effectiveness of the software.

Summary of the Pattern:

The “White Belt” pattern emphasizes the importance of approaching new learning experiences with a beginner’s mind, regardless of your level of expertise. It suggests setting aside previous knowledge and preconceptions to fully absorb new information. Drawing analogies from various fields like family therapy and programming, the pattern illustrates the benefits of adopting a mindset of not knowing. By embracing ignorance and being open to making mistakes, individuals can accelerate their learning and gain deeper insights.

Reaction:

As someone who takes pride in my skills, it’s easy to fall into the trap of believing I already know the best way to approach a problem. However, the “White Belt” pattern reminds me that there’s always more to learn and different perspectives to consider.

What to Do:

The pattern suggests practical steps to implement its principles. For example, it recommends trying to implement a program in a language with a different paradigm, or learning from someone in a different technological community to understand their perspectives. These actions challenge one’s comfort zone and encourage embracing new ways of thinking.

What I Found Thought-Provoking:

The analogy of wearing a white belt, signifying a beginner’s level, is powerful. It reminds me that true mastery comes from a willingness to continuously learn and adapt. Additionally, the idea of consciously unlearning and relearning is intriguing. It requires humility and courage but promises significant growth.

Changes in Thinking:

This pattern has reminded me in the importance of continuous learning and humility in any area of life. I aim to approach new challenges with a more open mind, ready to embrace the discomfort of being a beginner again. Instead of seeing setbacks as failures, I now view them as opportunities for growth.

Disagreements:

While I don’t disagree with the core principles of the pattern, I recognize that fully embracing a beginner’s mindset can be challenging, especially in environments that value expertise and efficiency. However, I do see a view of balance on where it can be useful to listen to new ideas/appreaches while incoperating past ideas. As I do not think the White Belt pattern suggest to blondly accept any and all new information without any rebuttals or input.

In conclusion, the “White Belt” pattern serves as a powerful reminder to approach learning with humility and openness. By unlearning and relearning, we can break through plateaus and continue our journey toward mastery.

For this week’s blog, I decided to research a bit on performance testing because it is listed as a topic for a class. While doing research, I found a blog called “How To Do Performance Testing: Tips And Best Practices” by Volodymyr Klymenko. In this blog, he discusses the primary purpose of this kind of software testing, types of performance testing, its role in software development, common problems revealed by performance testing, tools, steps, best practices, and common mistakes to avoid. The blog was well organized and clearly simplified each topic.

The purpose of performance testing is to find potential performance bottle necks to identify possible errors and failures. This is to ensure that the software meets the performance requirements before it is released. Some types are load testing(response under many simultaneous requests), stress testing ( response under extreme load conditions or resource constraints), spike testing (response under a significant and rapid increase in workload that exceeds normal expectations), soak testing(simulates a gradual increase in end users over time to test the system’s long-term stability), scalability testing(how the system scales when the volume of data or users increases), capacity testing (which tests the traffic load based on the number of users but differs in scope) and volume testing(which tests the response to processing a large amount of data).

The next section discusses the role of performance testing. I found some of the bullet points to be a bit obvious like “improving the system’s overall functioning”, “monitoring stability and performance”, and “assessing system scalability”. The other points mentioned were “failure recovery testing”, ”architectural impact assessment”, “resource usage assessment” and “code monitoring and profiling”.

After discussing the role of performance testing, the author discussed the common issues revealed by performance testing. The problems discussed were speed problems, poor scalability, software configuration problems, and insufficient hardware resources. This section is broken down into many bullet points to explain each issue. I found it to be very beneficial in simplifying the ideas presented.

The last three sections are the steps for performance testing, best practices, and common mistakes to avoid. The steps presented in this article for performance testing were: 1.Defining the Test Environment, 2.Determination of Performance Indicators , 3. Planning and Designing Performance Tests , 4. Setting up the Test Environment, 5. Development of Test Scenarios, 6. Conducting Performance Tests , and 7. Analyze, Report and Retest. The section after explaining the steps includes some best practices like “Early Testing And Regular Inspections “ and “Testing Of Individual Blocks Or Modules”. Some of the common mistakes to avoid that I found to be noteworthy were “Absence of Quality Control System” and “Lack of a Troubleshooting Plan”. While working on the Hack.Diversity Tech.Dive project, I had to do some performance testing and even used a tool that was mentioned in the article called Postman. In the future, I will definitely be more prepared to do performance testing now that I can reference this article.
