The second Apprenticeship Patterns pattern I looked at today is “Confront Your Ignorance”.
This pattern explains how to improve your knowledge in areas you aren’t as experienced in. The pattern also provides possible drawbacks of focusing too much on self-improvement.
The “Context” and the “Problem” sections of this pattern are relatable to me currently. I can clearly see that I have a problem with my knowledge of Angular and I need to learn more about this in order to develop frontend applications. I do somewhat disagree with the part of the problem area that says I “do not know how to begin”. I think at this point I have a decent idea of how to learn about new tools. Although maybe it is correct as I have still yet to feel like I have a good understanding of Angular after trying to learn more about it.
I do like and use both of the suggested methods for learning about new tools. Usually I like to read documentation and introduction guides on a tool’s website, but I also like to follow along with example projects. Additionally, I have found that watching a video tutorial series (mainly on YouTube) on a particular topic can help a lot with learning about something new. This is how I learned about a lot of the backend tools my team used this semester and I am especially a fan of the YouTube channel one of my teammates found. This suggestion is something that I feel should be included in this pattern as I have found this method to be one of the most valuable ways of learning about new tools, especially if there isn’t much documentation for it.
If I had to pick only one thing to learn more about it would be Angular. This is something I have consistently been trying to learn about for a while, ever since I first learned about it, and it has been something I’ve tried to improve on this semester but I am still not satisfied with my knowledge with this tool.
I did find the provided downsides to be the more intriguing part of this pattern as these are points I wouldn’t have thought to be in a pattern about how to learn new skills, but they do make sense after reading about them.
I do think that this pattern provides some good general information about learning about new topics, but for me I wish it was a bit more specific as I find that I was familiar with most of the information provided in this pattern about learning about new tools.
This morning’s pattern in Apprenticeship Patterns is “Expose Your Ignorance”.
This pattern helps explain to early developers how to get over their initial lack of knowledge in the field by asking questions and seeking out knowledge and the importance of doing this instead of pretending to know everything.
To me this pattern and especially the “Problem” area feels very relatable right now with where I am this semester, especially with another attempt at learning how Angular works.
I do find that this pattern provides me with some valuable reassurance, and it is more comforting to know that this problem happens to other people.
Lately with my work this semester I have apparently been following the advice this pattern gives and trying to ask others in my group for help when I don’t understand something that I have been trying to do. This is important in our group, especially as different team members in our group have their own areas of knowledge from what they’ve learned this semester. Reflecting back on this more I wish that I asked more questions (especially during meetings) and focused more about how something works instead of just the solution as this would have had a far greater benefit in increasing my knowledge.
I agree with the idea that answering questions helps to understand the problem better. I can think of many times this semester where I either asked questions that helped find errors in something or when answering someone else’s question made me think more about it.
I do like the idea that the “Action” section presents, although it does feel somewhat exposing to visibly have on display things I don’t know. I am trying to think of a good digital place to put something like this, perhaps on my GitLab account. As I’ve probably alluded to in my posts so far, I think my top items (although this isn’t five items as the pattern suggest, these are things that are particularly holding me back) with my current work would currently be: Angular (and specifically forms), HTML, and Jasmine (this is especially a rather new one for me). I would like to refine this list some more and pick more specific topics to work on learning in each one of these broader items.
This pattern provides helpful knowledge and helps explain the importance of learning from others. Again, as I said before in my previous post, I wish I read this pattern earlier as the ideas presented in this pattern would have improved my learning this semester.
Article link: https://dzone.com/articles/why-do-programmers-fail-to-write-good-unit-tests
In this blog post I wanted to examine an article I found about unit testing. I think that since unit tests were one of the first types of testing we learned about and we have used unit tests as a foundation for many other testing methods this semester, reviewing this article serves as a great retrospective (and provides another viewpoint) on the importance of unit testing and defining criteria on writing “good” unit tests.
In the article, the author defines the significance of unit tests in creating software. They then go on to define some various qualities that make for a “good” unit test. I agree with the listed points, but I think this article could benefit by providing a few examples of good unit tests and maybe a few bad ones for comparison, especially since this is an article about programmers not correctly writing unit tests. I also think the article could better define what these “units” that are being tested are, since this term is used frequently throughout the article. Additionally, I think the article should better define what specifically is being tested in these “units” besides just saying “examine and test each unit of code separately”. Again, this is where some examples would greatly help illustrate the author’s point. The article then goes to list many benefits of writing unit tests. It ends with an interesting (and great) point of how just having unit tests isn’t necessarily beneficial (and can even be detrimental) if they are poorly written.
Overall, I think that after learning about and using unit tests a lot this semester, that this article can serve as a good introduction to the topic, and it certainly reaffirms what I have learned about unit testing, but I also think it requires some revisions to be more helpful in demonstrating the points it makes, as I find it to be somewhat vague in the fundamental parts of presenting the main concept of unit testing. I think that having a well written article about this topic is especially important as this type of testing is used as the basis for many other types of testing we have learned about. I also think that this article could include this point of how unit testing is used in the larger contexts of other types of testing such as ensuring code coverage to further prove its importance.
Article link: https://dzone.com/articles/what-is-regression-testing-and-why-is-it-important
Today I learned about regression testing from an excellent article on DZone and why it is an essential part of software testing. As the article explains, regression testing involves testing the whole software product to ensure that any changes to the code doesn’t break what was already working in the product or other parts of the software. The article then goes through a great example of how fixing a bug in one part of an example piece of software can unintentionally result in another (previously working) part of the system to stop working properly. The article demonstrates really well that this breakage can occur despite unit tests showing that the bug was fixed properly. This to me is an especially important point as it shows the value in using multiple methods of testing to ensure software is performing correctly. One criticism I do have of this article is that I wish they gave an example of how to implement regression (the article does include a link to a tool that performs regression testing) testing in an actual program (or in context of their previous example).
Although after reading this article, the concept of regression testing seems simple, I find it very important as both a software user and software developer. In my personal experience as a user I have seen everything from operating systems to video games release updates that caused features that worked fine previously to become buggy or stop working entirely. From the user perspective I know how frustrating this can be, so I am glad that I learned how to prevent this problem as a software developer. Regression testing is definitely something I now want to implement into my personal software projects. Now I need to look into the tools that can help do this.
As we are nearing the end of the semester and about to finish our projects, I’ve been thinking more about the documentation process for the different parts including the frontend and backend. With this in mind, today I found a great topic about documentation generation for REST APIs with a tool called Swagger. I’ve never heard of Swagger before today, but it is a useful framework that allows for testing, documentation, and other useful features for building APIs. This post shows a quick little tutorial of how to implement Swagger for documentation generation with a Spring Boot project that is very similar to my project and the example REST API order system we have been using. It is a relatively simple process that includes adding the necessary dependencies for Swagger and adding a controller class for it, then all you have to do is just add the necessary documentation statements for each controller and requests within the controllers. The end result is a very nice-looking HTML page that displays a well formatted layout which includes the documentation for your API backend with a graphical display for each request and all the information associated with the request such as body and return information. Now as I was reading this article and this new way of creating documentation, I was comparing it to the way we’ve been doing it so far with a simple table written in Markdown for all of our API endpoints. The output of doing it in Markdown was nice but writing it was a tedious task with the formatting of the table. I much prefer the simplicity that Swagger allows you when adding a new endpoint. I also like the final product that Swagger produces a lot more than the simple Markdown document. In the future if I am creating another Spring Boot project, I am going to try to use Swagger from the start for documentation instead of using a Markdown document with a table for a basic readme as it appears that using Swagger makes adding new endpoints much less tedious with formatting. I would also like to try to add this to my current project if there is enough time, and also see if it is possible to use it with Angular too.
