During these first few weeks of class, we have been talking about JUnit and how it has features that allow us to test our code. We mainly talked about annotating methods to use as test cases as well as different assertions from Java and third-party libraries in order to help determine if a test was successful. While we kept using it throughout the week in order to help us test our code, I wasn’t exactly sure what JUnit actually was. Luckily when I was doing some research on it, I came across a blog on Parasoft by Nathan Jakubiak which gave a lot of useful information on what unit testing is, what JUnit is, as well as how to set up JUnit testing and to write different tests. I think that Jakubiak gave great descriptions as to what each of them are and what they are used for. Firstly, he stated “Unit testing is a form of white box testing in which test cases are based on internal structure. The tester chooses inputs to exercise particular paths through the code and configures assertions that validate the output. The purpose of unit testing is to examine the individual components or pieces of methods/classes to verify functionality, ensuring the behavior is as expected.” This means that unit testing is a type of testing where test cases are created based on certain parts of the program that you want to test, rather than testing the entire code in one test. For JUnit testing, Jakubiak stated “JUnit is the most popular Java unit testing framework. An open-source framework, it’s used to write and run repeatable automated tests.” Essentially he is just letting us know that it is an open-sourced framework that allows us to run different tests for our code. In his blog he also talks about how to set up JUnit testing which I personally don’t understand, probably because I just started working with it. However later in his blog he talks about all of the different parts of a JUnit test and how to write them. He also gave examples for some of the different parts, such as annotations, which I found to be really helpful in my understanding of the subject. I chose this Jakubiak’s blog because in all of the research I did on the topics of JUnit and Unit Testing, his blog did the best job of explaining them and overall gave me a much better understanding of the topics.

Have you ever heard a word or phrase that you feel like you should understand but you just don’t? It’s happened to many people, and I’m sure it is not uncommon in the software industry. Certain software terms are either confusing or unknown, which is perfectly understandable!

Chris Kenst’s blog post relates to what we studied in class this past week, as it correlates with and even mentions some of the terms we learned, such as black box testing. It will hopefully help the definitions we previously learned stick in my head as the weeks go by.

This blog post is all about lingo. It aims to better prepare students and software-testing newbies for the confusing jargon coming out of their coworkers’ mouths. It is in a simple glossary format, which is easy to understand and refer back to from time to time. There are 50 terms listed as well, so there may be some left out, but the ones listed are what you are most likely to hear in the workplace or in communication. Kenst also mentions at the end of the post that an increased mutual understanding of such terms can lead to increased productivity and collaboration.

I chose to cover this blog post because it is easy to get lost in all the mumbo jumbo tech buzzwords flying around the internet. It is like being a parent and learning what your kids’ slang means; except the kids are your coworkers and the slang is important keywords for your profession. I would not want to be the one guy at a meeting who does not understand “black-box testing” or what “domain testing” is. Jokes aside, this is a great resource for my fellow students to refer back to, especially as we are just beginning our software testing journey. These terms are important to know, because otherwise you might fall behind as new terms and testing variations are created. 

I personally believe this is a great starting point for those new to software testing (like me) and those who might need a refresher every now and then whenever their coworker says something unfamiliar. I learned how “high volume automated testing” involves auto generation, execution, and evaluation of multiple tests that may be weaker and not as thorough on their own, but together expose bugs and weaknesses. I will continue to learn more testing variations and other terms from this list to strengthen my confidence as a software tester and engineer. I hope to apply this knowledge in the future whether it be at a job interview or in a working environment, proving to my coworkers that I understand the language they are speaking and can keep up with their discussions.

The blog I chose was “Will AI Replace Manual Testers?” by Thijs Kok. The blog post highlighted the importance of testing for software development and the role that AI plays. I chose this blog for two reasons, one due to the fact that we recently discussed the types of testing in software development. The other reason being the rise of artificial intelligence popularity in the software and technology field. I thought this blog was able to highlight one of the main fears that people who are studying computer science or people who are already in the field have when it comes to artificial intelligence. This fear being is artificial intelligence going to be able to take over our jobs. We have seen just what artificial intelligence is able to do through a multitude of examples showcasing just how advanced the AI is when it comes to solving programming problems. For those reasons, that is why I chose this blog because I thought it would be interesting if AI could take over this aspect of the jobs we want.

The blog post started off by acknowledging the power AI has right now throughout the world and how the tech field is no exception. The author described three ways how AI is already being utilized within the software testing scope. These ways being test case generation through, test case execution and test result analysis. The blog post ended with the overall question, will artificial intelligence replace testers? The conclusion that the author reached was, no, “While AI can automate specific testing aspects, it cannot entirely replace human testers. The cognitive skills, creativity, problem-solving abilities, and emotional intelligence that human testers bring to the table are irreplaceable”. The author stated that even though AI can be very powerful it can be seen more as an enhancement rather than a replacement.

My overall take from this blog post is the importance in understanding how AI works and how to integrate to use it as a tool for the future. While we can’t use the AI to just do the work for us it can be a helpful asset that will make the job easier allowing us to focus our efforts on more important matters, things that the AI otherwise could not handle. I believe that the blog post was a great piece that anyone could read and take away various insights from. For example, it was able to downplay people’s fears on AI taking over as well as teaching people how to use it to their benefit allowing integrations for the future.
