We’re over halfway done learning about the SOLID principles! Today it’s time to learn about the “I”: the Interface Segregation Principle. In order to understand this principle, we first need to understand what an interface is. An interface is a definition of a set of methods that can implemented in a class. Each class that […]

It’s time to learn about the “L” in SOLID!  The Liskov Substitution Principle is named for Barbara Liskov, a computer scientist who introduced the concept in 1987.  The principle states that you should be able to replace objects in a superclass with objects of a subclass with no alterations in the program.  In order to […]

This month we are continuing our investigation of SOLID principles with the “O” value: the Open-Closed principle. This principle states the following: a class should be open for extension, but closed for modification. What does this mean? It means that once a class is used by other code, you shouldn’t change the class. If you […]

Those who have been reading my blog for several years have probably figured out that when I want to learn something, I challenge myself to write a blog post about it. In 2020, I read one book on software testing each month and wrote a book review. In 2023, I learned about one Logical Fallacy […]

One of the first things I learned as a new software tester was how much I hated test case management systems. If you aren’t familiar with test case management systems, they are tools that allow testers to keep a collection of manual tests for reuse. In the days before test automation was popular, they were […]

I often talk with testers who are feeling frustration with their manager. Some of their complaints include:• My manager doesn’t give me enough time to automate• My manager expects me to test all the sprint items at the last minute• My manager signs our team up for too much work• My manager doesn’t appreciate how […]

It’s a new year once again, and time to think about what improvements you and your team can make to increase the quality of your products! One complaint I often hear from testers is that they have become a bottleneck on their team. They feel constant pressure to get their testing done, and they feel […]

As you know, this blog has focused for the entire year on logical fallacies. We’ve learned about all kinds of fallacies, from the Red Herring Fallacy to the Appeal to Ignorance Fallacy! It’s time now for the last blog post of the year: the Slippery Slope Fallacy. The Slippery Slope Fallacy occurs when someone assumes […]

The Appeal to Ignorance Fallacy is an interesting one: it states that something must be true because it hasn’t been proven false. This fallacy is often used by people who believe in entities like Bigfoot, the Yeti, or the Loch Ness Monster: they will say that no one has proven that Bigfoot doesn’t exist, therefore […]

Equivocation is a technique used to mislead others through the use of imprecise language. There are many words in the English language that have more than one meaning, such as the word “light”, which could mean “bright”, or it could mean “not heavy”. It’s also possible to use equivocation by being deliberately ambiguous about time […]
