When we talk about testability we usually mean "hard to test". That is a whole discussion by itself, because "hard to test" is also subjective. If we follow the theme of testing as an investment to minimize future maintenance costs, then "hard to test" translates to "Costly to test" or "risky to test".
Understanding a software design proposal is so much easier once you can actually visualize it.
Crowdsourcing has had a pretty big impact upon most industries, but perhaps software development has seen a bigger impact than most. The rise of social coding sites such as BitBucket and GitHub have transformed the way software projects are undertaken.
One of the most poorly understood concepts in product/software development is incremental delivery.
The developer survey from DZone's 2014 Guide to Continuous Delivery gave us a few more insights than we were able to include in the guide. For a bit more detail on tool usage in Continuous Delivery, we've created this new infographic.
If you understand the definition of“average” you shouldn’t be offended by me calling a large number of programmers average or below.
The traditional Ops toolkit often involves a range of tools that help monitor trends in KPIs as well as tools that perform different periodic health checks on key components of your systems.
I recently put together an end-to-end demo showing step-by-step how to set up a Continuous Delivery pipeline to help automate your deployments and shorten your cycle times for getting code from development to production.
No one loves Null Pointer Exceptions ! Is there a way we can get rid of them ? Maybe . . .
Here is a quick solution for those encountering the “Failure to Transfer” error in Maven.
Influence debugging is an efficient active debugging method by which you can ignore a large part of your code during bug hunting. You can go backward along influences exclusively until you catch the bug. Tricky missing code errors can also be detected by this new method.
Often developers writing code that they think is useful and relevant while they are not listening to their target audience, in this case not the end users of the systems but the people that are maintaining the platforms. The people that work on a daily base with these tools.
The Javadoc for the ChoiceFormat class states that ChoiceFormat "allows you to attach a format to a range of numbers" and is "generally used in a MessageFormat for handling plurals."
It’s been 10 years since I wrote my first unit test. Since then, I can’t remember how many thousands of unit tests I’ve written.
The selection of a more modular architecture tends to result in an organization with more (smaller) teams.
How you can use the Graph analysis and visualization Tool Gephi to have a look into the Package Dependency structure of your Java Project with a "graph perspective."
One of the most frequently voiced criticisms of the Java programming language is the amount of Boilerplate Code it requires.
While Spock can be used for some property-based testing, ScalaCheck and ScalaTest may be your best option.
At JavaZone I attended many great talks by brilliant speakers, but one was really head and shoulders above the lot: “Software Design, Why, When and How” by Kent Beck.
Property based testing is an alternative approach to testing, complementingexample based testing
In this post I would like to show an example of how to use JUnit Rule to make testing easier.
This article represents top 4 security vulnerabilities related coding practice to avoid while you are programming with Java language.
If you are a web developer, it is a no brainer that much of your professional life will be spent using Java. Thus, this article lists 15 Java tools that can make your life easier.
Ruby unit testing feels very nice and natural to write with RSpec. However I still love Java (or for this particular example anything with strong typing) and is still my main language, and in many cases is superior to Ruby.
