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.

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.

Week 12

Considering that we have been working on the Mars rover for the past two weeks, I decided to find an article that correlated with this. I went straight to the source and found something about the actual Mars rover. I was able to find an article that piqued my interest. This article was specifically about the real rover and the people who worked on it. I chose this article to show the broad potential we all have inside the CS field that none of us even heard about. I hope to open your minds to all the possibilities you can do with code.

    The article begins by introducing the reader to Melody Ho a full-stack developer for the Nasa Mars website. She has a multitude of responsibilities she has to publish information about every mission and create data pipelines to be accessible to the public. Her journey began by working on a basic HTML book and playing computer games. She gives her reflection on her journey to inspire the next generation of women in space and technology. She most enjoys programming code that is efficient and adapting it to the best version of code possible. When she was growing up she was considering a career in computer games because she hadn’t yet seen the opportunities available for programming. She leaves the article by advising the next generation. She says to embrace new things and don’t be scared because these are opportunities that are needed to succeed. Technology is constantly changing don’t be discouraged if all doesn’t click it will take time.

   Reading this article gave me more of an introspective view of someone’s life in coding. This article doesn’t have much connection to the code we do in class but I think it’s very interesting to see the whole perspective of a coding journey. This article touches upon aspects that you may not think about every day but it gives much attention to what is important. Melody trying to inspire the next generation is very touching. She didn’t have to do this but she did. For me, it gave me a broader view of programming because sometimes you may have a tunnel vision of what you can do with your code but the possibilities are endless. There are a lot of connections that you may not see on an everyday basis. She mentioned how she double majored in business and I didn’t even see the correlation of coding in a management setting but it’s there. There are a lot of connections in programming with other skills there are some I haven’t thought about.

Week 11

Deciding on a topic this week I decided to delve into Test Driven Development (TDD). I found an article with an engaging title “Test-Driven Development (TDD): A Time-Tested Recipe for Quality Software” by Ferdinando Santacroce. This would be very useful for me and the whole class because it’s fresh in our minds and we will continue to work with this concept. Getting a firmer grasp on this topic will help me with future assignments and homework. It’s always great to get an insider view with experience inside the field connecting it to what we learn in class.

This article begins with the history of TDD giving credit to Kent Beck one of the first “extreme programmers”. At the time nobody had ever reversed the idea of testing starting with a test instead of the actual code. The purpose of writing a test before the code would help programmers put them in the perspective of the maker making it easier to create the software. This would make more tunnel-focused code with much more simplicity because of just focusing on the test. Plus the codes get rapid feedback because all the tests have been made. TDD has the fastest feedback loop only surpassed by pair programing. Currently, TDD is widespread inside the field and several teams utilize it day to day. It’s hard to adapt to this type of coding scheme but with time it is proven to be a key to success. Minor grievances may also come up because this type of process can be too rigid or the lack of tools.  

After reading this article getting a glimpse into the history of how this came to be. It didn’t specifically specify when it started but I assume it was around the 90s because it mentions how common it is now. Understanding the benefits of doing this test answers my question why would you decide to do your coding process in reverse? What we have been learning is that it will be conventional to have code and then write the test connected to the already processed code. The benefits of cutting down time because of the faster feedback times and leading to less complicated code, I now understand its purpose. That is a recurring theme with code the simpler the better because you are never working alone. Maybe it is a self-contained project but your future self may not understand your complex code and updates to the code should be easy to do not a headache.

Week 10 Blog Post

Searching for an article this week I looked for something relating to mocking. Considering last week I did the negatives on mocking I think it’s valuable to have various perspectives. Seeing multiple ideas with mocking can give us an idea of how to implement them in the future. The writer of this article is a reliable source being a Java script developer. Getting information from someone in the industry can give a perspective inside the workforce and how people inside see different ideas. Not everyone may agree with using the same coding language but seeing how developers see different concepts can give an idea of the drawbacks to stuff and where in our own experiences can we improve. Overall this article is a great way to see how mocking is seen inside the workforce by an experienced professional.   

In this article, Eric Elliot focuses on the drawbacks of excessive mocking. He points out how brittle tests and how they can be easily broken. There broken simply just from the change of implementation even though the behavior stays the same. Another point is a false sense of security because of there lack of accuracy that occurs from not using accurate real behavior. This is a fault in the test because the test will pass even if it isn’t supposed to. Third, he focuses on complexity overload which is just adding too much complexity can make the code harder to understand and maintain. Elliot still believes in mocking but a more balanced approach can overall help the program. Mocking should be used sparingly and when there actual weight for its use. All together Elliott wants the audience to create a strategy that will have confidence in their code correctness while also minimizing any negatives of excessive mocking. 

Reading this article at first I thought it would be more of a pro mocking but it’s more in between. It says its flaws while still sharing the positives. After reading this article I understand that mocking can cut time but it can bring flaws to testing. The best time to utilize mocking is when time is scarce and later it can updated with time. It still isn’t the ultimate be-all to testing but with a balance, it will work. Understanding these flaws can foresee issues that may come up when mocking. Mocking should never bring up complexities that can complicate the code and should always have a priority in simple to understand and easy maintenance.

Week 9 Blog Post

Choosing a topic for this week I tried to find something we had recently touched upon. Last week we went over mocking and expanding my knowledge of this topic can benefit me and the class. Searching for articles about mocking I stumbled upon one that shares the negatives of using mocking data. To counter-attack the ideas we learned in class it is always great to know both sides to using a concept. 

This article doesn’t fully dispose of mocking but gives ideas when it’s good to use. It gives a variety of examples including “Isolating the unit under test from other components or dependencies that are not relevant to the test, Speeding up the test execution by avoiding network calls or database queries that can be slow or unreliable, and Controlling the test input and output by creating predictable and consistent data that can be easily verified”. These ideas are then counterposed to the negatives such as “Introducing errors or inconsistencies between the mock data and the real data, which can lead to false positives or false negatives in the test results, Reducing the coverage and confidence of the test, by not testing the actual behavior and logic of the external source or the interaction with it, and Increasing the maintenance and complexity of the test, by requiring extra code and logic to create and manage the mock data”. The flaws of mocking data are mainly it does not use real data making it much more different from the real data creating disparities between the two. These tests ignore scenarios with much more complexity and these error and bugs can go unseen. The author assures the reader to use a data source to improve the tests.

After reading this article it gave me insight into the negatives of using mocking. The week prior activities made the use of mocking reduce time in creating classes but it’s good to know when it should be used and when it shouldn’t. I wish there was a perfect solution for every test but to find bugs in your code you must expand your horizon. Reading this article made me see that a variety of tests testing different things can overall benefit you. You never have to completely ignore a type of test but being able to see the positives and negatives can save you in the long run. Plus it will allow you to have a broader knowledge knowing that this may have flaws but there are things I can add to have a satisfactory end product.

Week 8 blog Post

For this week I found an article about writing code considering we have been writing classes for the past few classes. The article I found stuck out to me because of its title “Writing Code an Art Form”. People always use the analogy of code being like learning a new language but I never heard anyone consider it as art. From the countless articles I could have chosen without this title, I may have never chosen it to begin with.

This article first starts with a background of how the idea of this article came to be. The setup was that the author was working as a junior developer who had to get a recently hired senior developer with 10 years of experience acquainted with their program. I can only imagine how that interaction was set up and whoever was leading the group should have probably reconsidered who should help the new employee. Even though the senior developer had far advanced experience his code was not easily readable. The author was even taken aback because the senior developer commented how the author likes to write pretty code. The author goes into detail on how poor documentation must be taken into account because other flaws can arise from bad naming conventions for variables/functions, spacing, and having the mindset to problem-solve. Keep the code easy to maintain, read, and debug don’t write spaghetti code.

Now reading this article gave me insight into the inner workings of the tech field. I would have never assumed that a new employee would be getting trained by the second recently hired. I would have assumed that someone with more experience with the project would have filled in the new person but maybe it could be that there both coming from similar places. Both of them are the newest employees and could be easier to help another person adapt to the environment. Reading this article has also reinforced ideas that keep your code simple and clean. My main takeaway was whenever you write code don’t just write it for yourself to understand but for everyone. Let’s say you are working on a project on your own you might just get enclosed in how you understand code nobody but you will be able to update it. Even if you don’t care that someone else will update it in the future your code can be so unreadable that future you may have no idea what you created. In a way, code is like writing notes and there is an art to writing good notes.

Week 13 Clean Code

In my search for a topic this week, I searched for an article closely related to our homework and our last five Pogil activities. I kept it simple and looked for an article about clean code. I understand we have been loaded with tons of information about clean code but when was having more of something bad. I wanted to see different perspectives of clean code outside of class and what people inside the field or with experience opinions on. Allowing me to get insight from outside of class will be very helpful. Also, being able to have an open mind with coding can go a long way plus being able to see similarities with what I have learned and my own opinions. 

This article starts by describing the term “Spaghetti code” which refers to complex tangled code that is hard to decipher and causes frustration for everyone involved. This ties into clean code by emphasizing how is an integral component of software development and can only be maintained with practice. This comes with less team frustration and allows for any teammate to manage the code. Clean code is just not a statement of keeping the code tidy tightly but more of a form of communication that can be understood by everyone thoroughly. Software companies make big investments into clean code by hiring someone and paying them around $60-$100 an hour because of how vital it is for long-term success. An effective strategy to implement clean code is by grouping similar functions, utilizing whitespace, and “one idea per line” and “one action per statement”. To tie it all together your code must be consistent to adhere to agreed-upon team coding standards. Decisions that will help in the long run would be to add meaningful names, maintain simplicity, and apply comments effectively. 

With this article, I was able to learn a new term “Spaghetti code” that is self-explanatory and can remind me to keep my code simple and clean. I was able to connect many teachings from class including using meaningful names, abiding by team agreements, and utilizing whitespace. All these are valuable pieces in writing clean code that should always be in your mind when writing any piece of code. I was surprised at how much software companies invest in clean code and wasn’t expecting them to get paid that high. My main takeaway from the article was to keep my code consistent and simple. You may not think about these things but wanting to make things more complex can be a determent to all your previous work so being consistent will not only help you but your team as a whole.

Week 12 Project Coordination

While we have been working on our projects I have wondered what we should expect in our upcoming work. That is why I searched for an article that would give me insight into the later parts of our project. Just finishing up the project set up a few days ago will help me map out the rest of the project itself. I targeted my article on projects in GitLab to have a more precise understanding rather than a broad project understanding with no correlation to our own.  Hopefully, giving you the knowledge I gained will help your journey of developing your project.

This article gives the reader an insight into how GitLab coordinates its scheduling, planning, tracking, and releasing. To decide on their release date they use the Good Docs Projects template which emphasizes two updates per year. So for GitLab, they work from Jan – May release mid-June, then a three-week break, then back to work from July to December, have a release, then another break starting the cycle over again. In their six-month work, it’s similar to scrum where the team meets up in the beginning and establishes goals. During those months they do general community meetings to see if they’re on track and assign issues by weight of importance. On release day, all the team members meet up to build the team artifacts including their zip files and tarballs. If everything goes right and all their merge requests are complete they try to make sure everyone is credited and then go on a three-week vacation where the cycle begins again all over again. 

After reading this article it showed me a new and effective way to complete a project. This way of doing a project has many similarities to scrum but in the grand scheme of things, all you need is a cycle that is effective and can be repeated. In this particular project, I can’t use their scheme but I can try to concise it into a smaller scale understanding the time constraints. I think it’s very effective to have a break after finishing a project. Some people may want to take a break in between projects but in my opinion, it’s better to finish it overall then take time for yourself. In the article, there was no research on the effects of the break but I believe their workers come back replenished and ready to work when they do come back.
