QAn’t Wait to See You Again

CS SERIES (16)Before I dive into my final installment of this CS series (for now), I wanted to say thank you if you actually read any of these posts and thank you to my new followers for dealing with the notifications you must have gotten.

For this last post, I wanted to discuss the article 5 Reasons You Are Wasting Your Testing Time by Joel Montvelisky. The author expresses how everyone can do testing but not everyone can do “good testing,” which incorporates more than just what is basic checking.

A short list of main reasons why a lot of people tend to waste time that could have been spent testing other things includes:

  • Not having clear goals
  • Not understanding what or how much the feature means to your End User
  • Not keeping track of what was tested and potential discoveries
  • Not consulting what you already know or using references
  • Not giving feedback that could be shared to help others

Sam CS (22)I agree with most of what Montvelisky says as I have personally noticed what has happened from my experience as a Software Quality Assurance Intern when any of the five things above took place based on a task. It is important to understand that sometimes these things may be out of your control but you should still try your best to avoid miscommunication wherever possible.

Montvelisky’s content has not necessarily changed the way I will work as I have already been consciously making an effort to understand what I am reviewing, how stuff is meant to work, logging tasks, connecting tasks to previous occurrences, and communicating with the QA team. If I had read this article before I started working, it would have been more useful as it would serve as a foundation to how one should think of testing beyond the basic functionalities.

Something I wanted to emphasize is the post-test reviews and feedback sessions with peers. I found that if someone else needed to learn about a project or a task had to be communicated with a client, logging any kinds of notes or information was better than not having anything prepared to discuss. They do not necessarily have to be posted for everyone to access but it would be good to note it in any sort of text editor for future reference. I think an example of when to note things is if you found something that does not prevent your current task from being approved but it still affects something for the overall program.

Overall, when testing things I believe you should trust your instincts on reporting things you find. It helps when you try to imagine how much it could affect a program in the long run if not brought to someone’s attention, even if it may seem minimal.

Best of Luck,

Sam

Adapt or Git Left Behind?

CS SERIES (15)As my last fall semester comes to a close, I wanted to write about an article on something pretty interesting I learned about in my software construction and design course.

On Stackify, Thorben Janssen wrote Design Patterns Explained–Adapter Pattern (with code examples). Overall, this article re-instilled how design patterns make it easier to write more well-structured and maintainable code.

I found it useful to see how Janssen discussed the two different versions of the class adapter; the class adapter pattern (which implements the adapter using inheritance) and the object adapter pattern (which uses composition to reference an instance of the wrapped class within it).

Similar to how we learned the concept in class, something I appreciated is the “real-life” example or comparison used to describe the physical adapters we use when traveling. When we are traveling and do not have compatible power sockets, we must find a way to be able to charge our use our devices without having to change the whole make of it. A way of doing so is by using adapters; which does not change the overall product or device, it just allows you to be able to plug it in.

An situational example that I can think of when explaining adapters is if you have ever been zip-lining or done a ropes course (like Go Ape) where you are attached to a harness. When you are transferring from one line to another, you can use a metal contraption which helps guide you while connecting and disconnecting from paths. That metal contraption serves as an adapter, not changing what you are but allowing you to use something.

I agree with what message Janssen is trying to express about how great design patterns are (the adapter pattern specifically) when it comes to writing code. His content allowed me to think about real life situations in code form when he introduced the basic and premium coffee machines to brew coffee using the adapter pattern. One of the best ways of learning concepts, in my opinion, is to compare it to a real-life situation and then show people visualizations to help them better understand what you are trying to explain and the article did both.

Test Yourself Before You Wreck Yourself

CS SERIES (14)Testing, testing. I may need your approval on this article I read by Software Testing Magazine on Approval Testing. Approval testing, as defined by this article, is a way of software testing that results in presenting the before and after of an application for a user (ex: software development team) to review it and potentially approve it. It’s more of a visual representation of testing and one of the major cons is how the results have to be checked manually.

Some testing tools mentioned include: Approval Tests, TextTest, Jest, Recheck, Automated Screenshot Diff, Depicted (dpxdt), and etc.

The main purpose of the software testing tool, using TextTest for example, is checking that the text output after running program from the command line in different ways.

What I found interesting is how a user can see that a test technically could have “passed” or “failed” but still decide to mark it as the other because they choose what feature they are looking for in the end. This makes it a little more flexible to use approval testing as it is more of a guide or guideline for a user instead of only seeing one word and then a short description of what could have gone wrong. I think this process is much more transparent or descriptive with a user about what could have gone wrong or what went right.

One way the content has changed how I will think about the testing is how there are so many more types of software or programs out there than we can imagine which help us better code or create our own software and programs. This one is especially good for visual coders and testers who like to see their results firsthand to compare what they are expecting with what they actually got.

Overall, I found this article was useful because it introduced me to thinking about a better way of logging the differences between what the reference result is versus the actual result. I did not disagree with any of it since it showed us how we can use approval testing to our advantage while still being honest about its limitations.

Nice Demete[r] You

CS SERIES (12).pngThere are lots of “rules” we must follow in object-oriented software development and the article The Genius of the Law of Demeter by Javadevguy summarizes how they are useful. From what I put together, it seems like the Law of Demeter took abstract concepts and basically put them into a universal set of rules for Object-Oriented code.

I thought that the law of demeter must be a big deal if someone decided to sit down and write a lengthy blog post about it. This content ended up being interesting as it tried to convince readers why they should obey this “law.” The Law of Demeter basically paves the way for what users can do to a given method. It is kind of like considering the restrictions or possibilities based on the method. One of the takeaways I got from this is how there is a lot of focus on communication between two objects.

Sam CS (18)

The rules listed in the article are as follows–noting that it says “For all classes C, and for all methods M attached to C, all objects to which M sends a message must be”:

  1. self (this in Java)
  2. M’s argument objects
  3. Instance variable objects of C
  4. Objects created by M, or by functions or methods which M calls
  5. Objects in global variables (static fields in Java)

Another useful takeaway I got from this article came from observing the code examples Javadevguy included; how Rule #1 covers that any method can be called on the current object. I also noted when there would be an instance where the law would prohibit something is not “sending a message” to any already existing object that is held in instance variables of other classes.

This will affect the way I continue to do work as an Object-Oriented developer. I mean, in life when you learn there is a more useful or structured way to help you achieve more effective results, you would want to try or follow it, right? For my future use, I will acknowledge (like other blogs and articles) that the Law of Demeter is less of a law and only a suggestion or a guideline.

Overall, I would say that the content has helped further solidified my understanding of some Object-Oriented coding concepts. I agree with the content as it is trying to help people become better developers or better understand the Law of Demeter in general.

CS SERIES (10)If you happen to be reading this page translated from English to another language, hello there, you are one of the main characters of this blog post. Without linguistics, the study of language and its structure, we probably would not be able to figure out how to communicate everything we need to globally while being able to understand it at the same time while testing. There are so many online resources that cover what a specific country or region in a country uses in terms of data formats for their computer systems.

Stickyminds featured an article from Mukesh Sharma on Linguistic Testing: Setting Up Your Software for Global Quality. Sharma dives in by explaining what exactly linguistic testing is–which is testing not only localization but also internationalization. These words basically mean everything we are testing on the software either is or would be fully functioning across the globe.

I found this content thought-provoking as I never specifically thought about how developers and testers would have to consider culturally-aware attributes like the formatting for texts, dates, and currencies. As more and more people are gaining access to the internet across the world, that means there are even more and more platforms to test for gauging market readiness.

An example of a situation that could happen in real life I can think of when testing functionality on websites is for international shipping addresses. If a user, we’ll call him Zayn, from London, England is ordering something from a company based in Boston, Massachusetts (USA) and puts in his shipping address, it should not require him to select a “State” under one of the fields after he selects “United Kingdom / England” as his country option. If that field still requires Zayn to select a state when his country location does not have states, there is a problem.

This will change the way I think when I work as when developing code to solve problems or create something new, I will have to think about if the market or target audience goes beyond the USA. When testing the code, of course every possible scenario must be tested already but there will have to be more details to make sure it all goes smoothly–especially since international errors or problems usually take up more effort to fix as communication plays a big factor.

[W]in Tech

CS SERIES (9).pngOver the weekend, I had the chance to sit down and listen to another podcast episode by Developer Things. The title, Women in Technology (with Megan Horton), caught my eye as I am always on the lookout to learn about other women’s experiences in technology.

The podcast series’ goal is for people to learn new developer things each time they listen so here’s what I learned on the career side related to software construction, design, and architecture:

  • The stigma of “nerds” begins in elementary school so girls start to stray away from STEM even in the limited amount of programs there already are for computer science in earlier education years. This eventually results in the number of females in CS in universities–like mine–is so low along with the numbers of those who move onto the software development workforce.
  • There are jobs out there like writing software for watering fields based on whether the sun is up or down or varying weather conditions. It reminded me a bit about how we used duck stimulator as an example to learn UML diagrams and had different actions performed for each duck.
  • Career advancement is not always a straight path. People tend to switch into computer science as a major or switch into technology when they want a career change. I’d like to point out how the host of this episode took the opportunity to say Horton came from the funeral business to killing software bugs.
  • You won’t always have to write code: there’s so much out there–you could have a passion for anything and do something tech-related in that setting.

The content has caused me to think more deeply about what I will do in technology, I mean of course I’m going with software development or software engineering but what is the overall goal throughout my career timeline going to be? What kinds of companies will I end up working for? What projects or passions will I follow along the way? Overall, I enjoyed the podcast with Horton as she discussed the ups and downs of being a female in technology and her experiences in the industry so far.

I don’t think I was there for the time when people would be kicked off the internet because someone needs to use the phone as discussed in the episode but I do experience times when my connection isn’t consistent. It really makes me sit back and think about how technology relies on constant power and a steady internet connection.

A major takeaway that I continue finding myself writing about is how we will always be learning something new in technology as things are always changing–as long as the power is on.

Hey Siri, Google This

CS SERIES (8).pngImagine being several years into your role as a developer; you’ve had a long week, a big project to push tomorrow and suddenly… you’re stuck on something. And you’ve double-triple-quadruple checked to make sure everything is working by code review but you cannot put your finger on how it is not quite perfect. What’s wrong? Let’s find out.

This is the first course-related podcast I’ve listened to for a blog post and if this is one of the only podcasts you will listen to, I recommend this one.

Jonathan Cutrell started off the podcast by saying “If there’s one thing that makes developers self-conscious it’s probably their googling history–more specifically things that they google that they forgot how to do.”

People can talk about code for days but they do not talk about the toll of what a developer thinks of themself when they are stuck on a part of their code or need to rely on the internet for something. This honesty makes it easier for university students and entry-level developers to understand the pace they are learning at is their own and that not everyone is perfect at coding even after years of experience.

Something that changed the way I thought about this is how important it is to know the pattern or routine of a concept. Things Cutrell says great developers care about is how understanding patterns and principles transfers but not necessarily the actual code itself. “Great developers” focus on the overall concept instead of wasting time on the small details of a language.

Due to this thinking, I realized I never considered how a developer can be the best of the best in one language but if they had to convert it into another language, the translation would be a little different. The real life comparison to this would be if someone were speaking with broken English. This does not mean they are not smart in any way, it’s saying that they are focusing on the main idea instead of a small detail they are trying to get through. They use their time more efficiently by moving on to a big concept instead of worrying about the syntax that they can easily google.

Overall, I appreciate what this article brought up as I was expecting it to be about just googling things but it dug a little deeper and mentioned what a good developer should focus on.
