I was asked a question from someone learning how to automate with Java. I’ve rewritten and paraphrased the question below.
I see that JUnit is a way for a developer to write Unit tests because I want the outcome of the code to work as per assertions. JUnit is for Unit Testing. And Unit tests are written by developers. When will a tester use JUnit? ....

This article introduces json-values, a pure functional Java library to work with JSON. In this first article, we ll see some impressive recursive data structures to model essential concepts in software development like data validation, data generation, and parsers.
The first and most important virtue of json-values is that JSON objects are immutable and implemented with persistent data structures, better known in FP jargon as values. As Pat Hellan said, immutability changes everything.
It s a fact that, when possible, working with values leads to code with fewer bugs, is more readable, and is easier to maintain. Item 17 of Effective Java states that we must minimize mutability. Still, sometimes it s at the cost of losing performance because the copy-on-write approach is very inefficient for significant data structures. Here is wher ....

Event Notifier in Apache Camel Route

Event Notifier in Apache Camel Route
Apache Camel is an open-source, lightweight integration library. In this article, I will demonstrate the concept of events it allows and how to use them.
by
Introduction
Each step of an Apache Camel Application triggers an event that allows us to read or edit data while the message travels on the Route. The provided mechanism to access these events is the
EventNotifierSupport class.
Apache Camel s route is a sequence of steps, executed in order by Camel, that consumes and processes a message. The initial point of this sequence is represented by the method
from(). A route may have many processing components that modify a message or send it to an endpoint. ....
