Have you ever felt like your career path doesn’t quite fit the mold provided by your employer or the traditional trajectory laid out by society? You’re not alone. In fact, many professionals find themselves in this position, yearning for something more but unsure of how to break free from the constraints imposed by their current roles.

Enter the concept of “Drawing Your Own Map.” This pattern, inspired by real-life stories and experiences, encourages individuals to take the reins of their career paths and chart a course that aligns with their aspirations, interests, and values.

Imagine this: you’re at a crossroads in your career, feeling dissatisfied with the options presented to you. You realize that your employer’s idea of your career path doesn’t quite match your own vision. What do you do? You draw your own map.

This concept urges you to identify an ambitious yet logical next step for your career, irrespective of what your employer or career counselor may suggest. It’s about taking ownership of your professional journey and understanding that you have the power to shape it.

But how do you go about it? Start by visualizing the smaller, interim steps needed to move forward. These steps may seem insignificant at first, but they generate the momentum necessary to propel you toward your goals. It’s about taking that first terrifying step, even without a perfect plan, and trusting that you’ll figure it out along the way.

One of the most thought-provoking aspects of this pattern is its emphasis on defining small, achievable goals. By breaking down your aspirations into manageable tasks, you not only make progress but also gain valuable feedback that informs your journey.

Perhaps what’s most inspiring about this approach is its recognition that there’s no one-size-fits-all path to success. Each individual’s career map is unique, shaped by personal values, interests, and circumstances. It’s about finding your own route through the wilderness, even if it means deviating from the norm.

Now, you might be thinking, “But what about external constraints? What if economic conditions or family responsibilities limit my options?” Valid concerns indeed. The pattern acknowledges these challenges but encourages you to find creative solutions and challenge accepted norms.

In conclusion, drawing your own career map is about embracing personal agency, taking calculated risks, and continuously adapting to change. It’s about recognizing that your professional journey is yours and yours alone, and you have the power to redefine it at any time. So, grab a pen and start drawing your map. Who knows where it might take you?

I recently read quite a few blogs regarding test-driven development (TDD), with many of them referencing behavior-driven development (BDD). This left me curious to learn about BDD and how it was different from TDD. Phillip Rogers does a great job breaking down what BDD is, the three principles of BDD, and some examples of BDD with Gherkin in his blog: “Behavior-driven development principles and practices.” (https://blog.logrocket.com/product-management/behavior-driven-development-principles-practices/#:~:text=Behavior%2Ddriven%20development%20(BDD),%2C%20domain%2Dspecific%20scripting%20language.) 

What is Behavior-Driven Development?

Behavior-driven development (BDD) is a product management approach focusing on defining system behavior from the user’s perspective. It emphasizes user interaction, collaboration among stakeholders, and aligning the product with user needs. BDD is a test-first development method.

3 Principles of Behavior-Driven Development:

1. What the software could do: Discovering and understanding customers needs to avoid building the wrong features. Techniques like impact mapping help prioritize features based on customer value.

2. What the software should do: Collaboratively writing structured documentation (executable specifications) articulating user needs. This involves using scenarios and examples in a given-when-then format to describe user behaviors.

3. What the software does: Automating desired behavior based on specifications, writing code, and iteratively improving both code and tests. This aligns with the test-driven development (TDD) process of writing failing tests, writing code to pass tests, and refactoring.

Behavior-Driven Development practices:

Impact mapping: A visual technique that reinforces what user outcomes are most important and are therefore more important to the project.

Story mapping: A visual technique that is used to maintain an understanding of what specifications are needed for a feature.

Three amigos: Forming sub-groups with different skill sets to work together. This brings different perspectives and thought processes into groups that may not have been there otherwise.

Benefits of Behavior-Driven Development

BDD being focused on the users’ perspective gives an improved understanding of the users’ goals. The tests created for BDD are typically higher level tests covering user scenarios. This ensures a high test coverage. Other benefits include enhanced collaboration, code reuse, and reduced rework as required changes are more likely to be seen early on.

Behavior-Driven Development vs Test-Driven Development

BDD and TDD are both test-first development methods that require planning and understanding of the project before beginning development. So, how are they different? TTD is mainly focused on the functionality of a feature. Whereas, BDD is focused on the users’ experience with that feature. BDD is more focused on testing specific scenarios a user may encounter. One notable difference is the fact that a single developer can do TDD where-as the amount of insight needed to do BDD requires everyone from developers to stakeholders,

For this week’s blog, I decided to research security testing because we didn’t have the chance to go over it in class. While researching, I found a blog called “Security Testing: Types, Tools, and Best Practices” by Oliver Moradov. The article is split up into a few main sections: “What is Security Testing?”, “Types Of Security Testing”, “Security Test Cases and Scenarios”, “Security Testing Approaches”, “What Is DevSecOps?”, “Data Security Testing”, “Security Testing Tools”, and  “Security Testing Best Practices”.

The first section “What is Security Testing?” explains the definition of security testing then spits off into two sections that explain the main goals and key principles of security testing using bullet points to organize the information. Security testing determines if the software is vulnerable to cyber assaults and evaluates the effect of malicious or unexpected inputs on its operations. Security testing demonstrates that systems and information are safe and dependable and that they do not accept unauthorized inputs. It’s a type of non-functional testing that focuses on testing if the software is configured and designed correctly. The main goals of this kind of testing are to identify assets, risks, threats, and vulnerabilities. It gives actionable instructions for resolving detected vulnerabilities and can verify that they have been effectively fixed. The key principles of security testing are confidentiality, integrity, authentication, authorization, availability, and non-repudiation.  

The next section provides multiple sections that delve deeper into the multiple types of security testing. The examples provided are penetration testing (ethical hacking), application security testing (AST), web application security testing, API security testing, vulnerability management, configuration scanning, security audits, risk assessment, and security posture assessment. I knew about a few of these types of security testing. However, it was interesting to learn about API security testing and security posture assessments. It provided information like how APIs allow attackers to gain access to sensitive data and utilize them as an entry point into internal systems and the basics of what a security posture entails. 

The blog then discusses some important test scenarios like authentication, input validation, application, and business logic then provides other tests in a bulleted list. It then discusses the types of approaches ( white box, black box, and grey box testing) and a few useful tools.

The next section that I found very important was the section about best practices. The best practices mentioned were: “Shift Security Testing Left”, “Test Internal Interfaces, not Just APIs and UIs”, “Automate and Test Often”, “Third-Party Components and Open Source Security” and “Using the OWASP Web Security Testing Guide”. I knew about some of the practices like automating and testing often and testing often but I did not know about the Web Security Testing Guide (WSTG). I like the fact that the author provided a link to that resource as well. I think this blog is a great resource for those who want to learn about security testing. It is well organized and made me feel like I’m a bit better prepared to enhance security for future projects.

The “Stay in the Trenches” pattern is a reflection of the temptation to prioritize promotions and managerial roles over staying engaged in programming, which is usually a developer’s passion. This pattern draws attention to the societal pressure to achieve success with upward mobility, highlighting the importance of sustainable motivations and the long-term commitment required for mastering software development. The pattern begins by addressing the common idea of being offered a promotion away from programming due to someone’s proven track record of delivering amazing work. While promotions are usually seen as signs of success this pattern challenges that notion. It emphasizes the risk of losing touch with the craft and the journey toward mastering when you step away from programming roles. The solution is to resist the given promotions that take you away from programming. Instead, it encourages people to negotiate with their employers for alternative forms of recognition and rewards that allow them to stay in programming. These alternatives may include increased pay or non-traditional technical leadership roles that still involve hands-on coding.

The main message of the “Stay in the Trenches” pattern is about keeping the passion for software development. Its about staying true to one’s love for coding and finding ways to balance career growth with meaningful work in programming. By rejecting promotions that lead away from programming, individuals can maintain their passion and commitment to the craft. This pattern challenges the usual idea of success and encourages to rethink of what truly motivates us in our careers. It helps remind us that staying connected to our passion and purpose is important for long-term fulfillment and excellence in software development. This pattern has made me rethink the usual idea of career advancement and success. It shows the importance of staying grounded in what I love to do and finding ways to align my career growth with my passion for programming even though the idea of the promotion maybe. This pattern has changes the idea that true success lies in finding joy and fulfillment in the work we do, even if it means resisting the loads of promotions that might take us away from our passion. The “Stay in the Trenches” pattern is a important pattern that reminds us to nurture our passion for software development by staying engaged in programming roles. It challenges us to focus on meaningful work over success and encourages us to negotiate for rewards that relate with our motivations and values.

With artificial intelligence increasing computational power and variability in usage, I wondered what advances were being made with AI. The tedious and repetitive aspect of test-driven development can sometimes leave the development process stagnating, so I was interested in how AI is changing the software testing process. This blog post, AI for Unit Testing: Revolutionizing Developer Productivity, by Philip Riecks, expands on how AI is improving the quality of our code and the productivity of our developers. 

The article highlights AI’s revolutionary steps in software testing and development. It discusses tools like IDE plugins that act as digital coding assistants and surveys from GitLab that show a significant increase in AI usage and demand for AI testing solutions. Philip explains the benefits of AI, which include streamlining test creation, boosting developer productivity, reducing developer fatigue, and many more. The article addresses why developers hate unit testing, highlighting the importance of it despite its tedious nature. It then gives an assortment of those tools with a small explanation of their specialization.

I found this article very enlightening, especially regarding the impressive abilities of AI-driven tools. My first thought when thinking of AI is to fear for developers’ jobs or worry about copyright infringement. It is nice to see that the focus of AI tools based on this article is to help developers by removing tedious tasks and allowing them to focus on improving the code. One of the sections mention AI’s ability to use user stories to generate test cases automatically. This was particularly interesting to me because a big part of behavioral-driven development involves using user scenarios when developing tests. Having AI take the workload off those using the BDD method would significantly increase productivity.

While reading, I still worry about the experience of those who use AI. If AI predicts defect areas, creates tests, and assists you every step of the way, how will that affect your ability to do those tasks? I also wonder if it matters if our abilities are lowered if we always have the tool at our disposal anyway. I imagine it would end up the same way we use calculators. We learn and can do calculations, but use the tool for convenience. Overall, I’m cautiously excited about AI, the stress taken off developers’ shoulders, and the increased time they will receive to focus on enhancing their projects.  

In the future, I will endeavor to learn more about AI, focusing on current and upcoming tools. When I use these tools, I will use them as an assistant and not as a crutch.

Unit Testing

Unit testing is a process in software testing where the smallest functional unit of code is tested. A common practice for unit tests is to first write the tests as code. Then the test code can be run automatically when changes are made. Doing this allows errors to be found, and isolated quickly if a test fails. Automating tests helps to ensure that efforts are focused on coding, rather than running tests.

As stated previously, a unit test is a block of code that verifies the accuracy of the smaller blocks of the code such as a function. The unit test checks that the block of code runs as expected, determined by the developer’s logic. A block of code may have more than one unit test assigned to it, in order to cover the full behavior of the block of tested code.

A block of code cannot be tested using a unit test because a unit test cannot use external data. Therefore the unit test needs to run in isolation. Because unit tests must run in isolation, this helps to improve the design of the code base to ensure that no function relies too heavily on other parts of the system. Doing this prevents code smells which can lead a rigid system due to insufficient modularization.

Unit testing strategies

There are strategies used when creating unit tests to ensure coverage of all test cases. Some of these strategies include error handling and numerous checks such as logic, boundary, and object oriented. Boundary checks and error handling are similar in the sense that they both check the behavior of the system based on inputs that are invalid/outside the expected input range. Object oriented checks ensure that the state of persisted objects are updated correctly. Lastly, logic checks ensures that the system performs as expected given a valid input.

Benefits of unit testing

A major benefit to unit testing is the increased efficiency when testing code and discovering bugs. Whenever the system code is changed, the same set of unit tests are run. If a test fails, it is easy to identify what caused the failure because tests are small and isolated. Therefore, unit tests help catch any bugs before the system reaches production. Another benefit to unit testing is unit tests act as another form of documentation. Unit tests act as documentation because developers can read the tests to see how to code should behave. Having accurate documentation is an important part of software, so that other developers know exactly what the expected behavior of the code is.

Conclusion

This article was chosen because I enjoyed that it explained when unit testing is less beneficial unlike other resources. This allowed me to understand when unit testing should, and should not be used. I enjoyed learning more about unit testing outside of class as it is such as integral part of software development. Therefore, I plan to implement unit testing in future projects to ensure system accuracy.

Software testing is essential in software development, Static and Dynamic testing are two different approaches in software testing that are important in making sure the quality of the software is good. This source goes into detail about these two different testing approaches and their significance in ensuring top-notch software quality. It gives an understandable guide that breaks down the core concepts of both static and dynamic testing, highlighting their objectives, types, automation possibilities, and crucial decision-making factors. I chose this resource because it shows the idea of software testing in a way that’s easy to understand and the difference between static and dynamic testing. Static testing involves reviewing code and documentation before execution, aiming to catch any defects early in the development cycle. Dynamic testing focuses on validating software behavior during execution, ensuring it meets specified requirements and performs as expected in various scenarios. What interested me the most was when to use each approach and how it works in identifying errors. Static testing identifies coding errors early, contributing to improved code quality and easier maintenance. On the other hand, dynamic testing is important for assessing how software behaves in real-world scenarios, performance, and security.

I can see myself using what I’ve learned about static and dynamic testing, I could be using these testing techniques in my future projects and by having a choice on testing before or during the execution of the code. This source emphasizes the possibility of automation in dynamic testing, which aligns perfectly with efficient testing practices. Learning about automation opens up exciting areas for streamlining testing processes and enhancing overall software development efficiency. Static and dynamic testing are important in software development and testing. This source helps show the relationship between those two different approaches and how they contribute to building reliable, high-quality software. Both types of testing are good it just depends on whether you would want to test in the early stages like during code review or the execution of the code. Static and Dynamic testing techniques are vital in software development and they both complement each other by reviewing the softwares quality.

JUnit is a popular Java testing framework that makes unit testing, test-driven development, and code writing more efficient for the development team. We discussed JUnit extensively in class. I wanted to discuss an article that provides a comprehensive guide to JUnit so those new to it can understand its fundamentals and importance to software development. This article, JUnit: A Complete Guide, by Shinji Kanaiis, is a valuable resource for beginners to JUnit and those who want a brief refresher. 

The article starts by highlighting the importance of reducing the number of defects early in the development process and how JUnit facilitates that through specific and efficient testing. It explains that JUnit can do this because its testing framework allows developers to write tests that target the functionalities of individual pieces of code. Without summarizing the article completely, I’ll briefly list its talking points. The rest of the article describes several aspects of JUnit, the most important being how it works, the benefits of using JUnit, how to install JUnit, JUnit assertions, and a step-by-step guide on making JUnit projects and tests. 

This article gave me an excellent refresher on what makes Unit Testing and, in turn, JUnit necessary. It is a modular type of testing that does not limit you to testing the entirety of your software but allows you to test individual classes and methods. It enables developers to fine-tune their testing process to find bugs efficiently. I also better understood its effectiveness when combined with test-driven development. Test-driven development focuses on testing first and developing code second. JUnit allows for better test-driven development because developers can efficiently test each case, method, and class until their code functions correctly before moving on to development. The article also talks about the vast resources and tutorials that JUnit has due to its popularity and ease of use. This aspect of JUnit reinforced my choice to write about it because it can be an excellent starting point for those new to Unit testing or software development. The explanation of assertions we discussed in class was enlightening, and there were some assertions that I was unaware of. This article was a great refresher on JUnit’s place in the development cycle and what makes it an excellent resource for software developers. 

I plan to use JUnit in future projects and make my code as modular, adaptable, and bug-free as possible. I will also point those new to JUnit towards this article or other resources so they can better understand how to get started.
