WWJD? What Would JUnit Do?

CS SERIES (7)A few weeks ago, I was introduced to JUnit testing in my Software Quality Assurance & Testing course. The blog post tutorial linked below is one I would recommend to those interested in learning about assertion. Reading this post has helped me review the concepts I have learned and I will share what helped me better understand the topic of writing basic assertions with AssertJ.

I found this content useful as it started off by covering whether a user had Maven or Gradle for declaring the dependency and then we get to dive into scenarios when a certain feature would be used. Some examples of what you can test with assertions includes: boolean values (true/false), whether or not something is NULL, comparing the result with a number or string (EqualTo()), object references, and arrays that are equal.

There is a walk-through of what we want to test with a basic scenario of when we would want to use it and this information makes me appreciate how much this kind of testing helps simplify things. It adds more structure to what we would like to do and by being able to import it, saves us so much more time in the end.

Honestly, in class I tend to spend more of my time trying to follow steps instead of absorbing what the material is and this article really helped me realize things like “oh, so this is why we use this line of code” or “so that’s why this is always there.” As a visual person, I appreciate the articles which actual include code examples for us to see what’s being used or added to explain a concept which was very helpful in this case. I do not disagree with any of the content provided as it is much more technical and there is reasoning behind each part of the process.

Overall, I would keep this article bookmarked and may come back to use it as a reference whether it be for a future testing assignment or just for trying to refresh this in my memory. As a side note, installing gradle on our laptops in class enabled us to run our tests through the terminal which was a pretty cool experience.
