Good day, my dear reader! As I continue my education in Software Quality Assurance, I continue to read blogs and keep finding myself reading a blog about how to do one particular topic, or how to test in one specific method. Now those reads were all good and useful but one particular article caught my attention, “5 Reasons you are wasting your testing time“. Now I will admit, I did succumb to the very obviously clickbait title but, this was one title I am glad that I followed. In class, there is a lot to learn but some things are best learned on the job or get glanced over or forgotten in the classroom. This particular blog was about 5 ways to review your testing time and see where you are wasting yours.

The first way is not setting a clear goal. Establish a goal for the testing session and ensure that by the end of your testing session, the goal has been met. The second way is that you might not understand the value of the tested feature to the end user. This is saying that, while we are tasked to test a feature we should keep in mind if this feature actually is useful or helpful to the end user. The third way is that one doesn’t keep track of what was tested and your finding. This boils down to that you need to be able to adapt your tests as you are testing. Fourth is not consulting existing information to get testing insights. The last reason is refusing to do post-test reviews or feedback sessions.

The first thing that popped out to me is the consideration for the end user. This is definitely something that is not talked about in class. It’s something I keep running across and I hope I can keep it in mind as I head out into the job market. The end goal is to create a usable, program that an end user will actually use or purchase. The next thing that jumped out at me is that some testers, “…who say they consciously prefer not to see the previous test-runs or the bugs found in an area of the system in order to avoid any bias towards those areas during their current testing session.” I found this kind of silly that some people see testing a program like a clinical double-blind study. When I hear testing, I think of video game testers effectively ramming their heads against a particular part of a game until it breaks or they do. While I doubt I will ever have this mindset, it’s always good to know what to avoid. The last thing that caught me was that testing, “While at the same time it is an art, as you need to (almost instinctively) know how to adapt and change your testing based on actual stuff you find along the way.” This caught me off guard admittedly. Testing does seem dynamic to me but not in that sense of having to change the nature of a test mid-session. This is something that I will have to remember and try to put into practice out in the field.

Thus ends another blog and another week of discovery and learning. I can only wonder what I will learn next week and I am definitely excited to find out. Until then, have a good night folks!

This week’s reading is a blog about conducting code reviews properly by Kamil Lelonek. It gives a general overview of code review as a process of giving feedback about another person’s code. By utilizing this process of rejecting and approving certain changes to the codebase, it will generate improvements as a whole. However, it goes much further beyond code review as it is not as simple as it seems. Even though benefits such as catching bugs early and ensuring that the code is legible and maintainable moving forward. The post makes it important to realize that developers are very protective about the code that they write and will attempt to defend against criticism. So, it provides different approaches to mitigating problems that could rise while undergoing code review. The benefits of these approaches should be able to correctly reach out without appearing as a threat. Some of these techniques would be to distinguish opinions from facts, avoiding sarcasm, and being honest with yourself. Also, by understanding the ten tips provided, it should make code reviews more effective for everyone involved.

What I found interesting about the article is how straight forward it is towards addressing one’s ego. They are right when they say that developers would like to say that they have wrote good code but sometimes they need to leave the ego behind them. By not opening themselves to criticism and addressing it as threats is detrimental to the team as a whole. Also, when actively code reviewing, I can see that providing evidence for nitpicking at certain lines of code should make it easier for the reviewee to understand what you are addressing specifically. However, I believe that avoiding jokes and sarcasm should be remembered as top priority. Especially when you are reviewing code for a friend. Recalling from personal experience, I do believe I did not help my peer to the best of my abilities by using sarcasm during code review. This also applies to distinguishing opinions from facts where sometimes through practice, you are led to believe that one technique is better than another. In conclusion, these tips are great for improving code review sessions.

This week I read a post of Joel Spolsky, the CEO of Stack Overflow. This post talks about the term “simplicity” when we refer it to a software product. There have been an old ‘80/20’ rule meaning that 80% of the people use 20% of the features. So, you convince yourself that you only need to implement 20% of the features, and you can still sell 80% as many copies. Unfortunately, it’s never the same 20%. Everybody uses a different set of features. In a period in the past, dozens of companies tried to release ‘lite’ word processors that only implement 20% of the features. Most of the time, they gave their program to a journalist to review, and the journalist reviewed it by writing their review using the new word processor, and then the journalist tried to find the ‘word count’ feature which they needed because most journalists have precise word count requirements, and it was not there, because nobody in the target 80% would use this feature. The journalist ended up writing a story that attempted to claim simultaneously that lite programs were good, bloat was bad, and he could not use this program because it would not count his words.

Making simple with 20% feature products is an excellent bootstrapping strategy because you can create them with limited resources and build an audience. So, you sell “simple” as a wonderful thing and coincidentally, it’s the only thing you have the resources to produce. Bootstrapping strategy has advantages in certain situations, however, it would not be good for long term strategy because there’s very few obstacles to prevent the next two-person startup from cloning your simple app, and because eventually you can’t fight human nature of wanting the features.

Success is a result of a combination of things: building an audience, evangelism, clean and spare design, emotional appeal, aesthetics, fast response time, direct and instant user feedback, program models which correspond to the user model resulting in high usability, and putting the user in control. All of these features share a common character of having benefits that customers like and pay for, but none of them can really be described as “simplicity.” With many years of experience running his own software company, Joe Spolsky saw that nothing he have ever done at Fog Creek has increased the revenue more than releasing a new version with more features. When a new version came out with new features, there was a sudden, undeniable, substantial, and permanent increase in revenue.

It is fine to use the term “simplicity” to refer to a product as meaning that the user model corresponds closely to the program model, so the product is easy to use. More, it is fine to use the term “simplicity” to refer to a product with a spare, clean visual appearance. However, if you think simplicity means “not very many features” or “does one thing and does it well,” you can’t go far with a product that deliberately leaves features out.

This blog from Microsoft Developer is related to what we are doing in class, specially to the final project. “Simplify REST API development for modern Single-page apps with SQL Server” by Jovan Popovic, talk about Single page app architecture, persisting JSON models in database.

First is single page app architecture – end-to-end, similarly to what we are doing in class, there are 3-tier pattern architecture in single-page applications.

Client-side is from users view, from web apps or mobile apps, this using frameworks or library such as Angular, JQuery, ect. This side executed and communicate with some middle application via REST API, then provides or accept data as JSON. JSON requests obtained from client-side and create some SQL queries to get or store data to the database.

If the client wants to get the data from the database, developer would need to add a few sub-layers in the applications layer. Developer would have some data access component to execute the query and fetch data, then some kind of “view model” to view the results of the query. The objects would take that information in JSON format to display to the client.

Second part is Persisting JSON models in database, as we know many modern web applications is running on the client side. We can use frameworks that enable developers to maintain state of the application on the client side. When the application saves the state being sent to the app layer via REST service.

To save the state provided by client-app, developer need to analyze JSON text from the client, use some data transfer objects and save data transfer objects into the database.

This blog cover mainly back-end of REST API. To show Built-in JSON functions in SQL and SQL Database, enable you to simplify your application layer code and work with database using the format that is already used on your client-side apps. I thought this blog somewhat useful since we learned about Angular, Node.Js and SQL in database class. I want to learn how all that fit in with each other. Web design really good and useful skill to have, specially this is how we view the internet though our eyes.
