When I’m writing new software, one of the most important thoughts in my mind is how I’ll test to make sure it works. There are lots of ways to test software, and when you’re at your best, you should be using all of them. Sure, you should make sure that your QA team is able to verify that your code …
Don’t be that developer who is woken up in the middle of the night because of some problem with the web application. After all, you need your beauty sleep – some of us more than others. The best way to avoid problems with your application is to test thoroughly. Of course, there is a cost to testing, and it is …
For Agile and DevOps teams trying to move the needle of progress, CI/CD has become the gold standard. High-performing teams are “shifting left” by automating more and more steps of the software development lifecycle. CI/CD helps teams deliver more value to customers faster by removing manual processes and minimizing human error. However, Agile and DevOps teams continue to fall short …
JUnit 5 is the updated version of the highly popular testing library for Java applications, JUnit, scheduled to be released in Q3 2017. The new version enables a lot more testing options and finally adds support for Java 8 features. In fact, JUnit 5 requires Java 8 to work. The library is composed of several modules, organized in 3 main sub-projects: JUnit …
Every company wants to see their company getting press and media attention. Unless it is due to a hacker and a security breach. Every few weeks you see in the media stories of companies who were hacked. Getting a new credit card every few months because the data was hacked has been routine for most of us. The more that …
Software development, as a profession, has evolved in fits and starts over the years. When I think back a couple of decades, I find myself a little amazed. During the infancy of the web, hand-coding PHP (or PERL) live on a production machine seemed perfectly fine. At first blush, that might just seem like sloppiness. But don’t forget that stakes …
When you hear the term “software testing,” do you think about one particular type of test — such as functional testing or regression testing — or do you immediately start visualizing the complex, interconnected web of test types and techniques that comprise the broad world of software testing? Most experienced developers understand that software testing isn’t a singular approach, although, …
We talked a bit about the Software Development Life Cycle (SDLC) in a recent post, but today, we’re going to dig a little deeper into one particular and crucial element in the testing phase, particularly for Agile development: regression testing. Definition of Regression Testing Regression testing refers to the process of testing a changed or updated computer program to make …
A Definition of Functional Testing Functional testing is a type of software testing that evaluates the performance of individual functions of a software application. The purpose of functional testing is to ensure that the application and all of its individual functions work as they should in the real world and meet all requirements and specifications. It’s a valuable testing method …
As I’ve mentioned before on this blog, I have a good bit of experience writing unit tests. In fact, I’ve managed to parlay this experience into a nice chunk of my living. This includes consulting, training developers, building courses, and writing books. From this evidence, one might conclude that unit testing is in demand. Because of the demand and driving interest, …
What is Unit Testing, Tutorial and 6 Best Practices When I started in this industry, only an avant-garde fringe unit wrote automated tests for their code. Over the last 15 years, however, that number has exploded, and the practice has become mainstream. But “mainstream” does not mean “universal.” Plenty of folks still do not have comfort with or even exposure to the …
If you enjoy the subject of human cognitive biases, you should check out the curse of knowledge. When dealing with others, we tend to assume they know what we know. And we do this when no justification for the assumption exists. Do you fancy a more concrete example? Take a new job and count how many people bombard you with company jargon …
