Why unit test with Groovy?

Tutorial Details:
The secret to Groovy's success, in this regard, is its syntax, which is Java syntax, but with far fewer rules. For example, Groovy doesn't require semicolons, and it makes variable types and access modifiers optional. Moreover, Groovy makes use of the standard Java libraries you're already familiar with, including Collections and File/IO. And, finally, you can utilize any Java library from within Groovy, including JUnit.
The fact is, Groovy's relaxed Java-like syntax, its reuse of standard Java libraries, and its rapid build-and-run cycle make it an ideal candidate for rapidly developing unit tests. But don't just take my word for it; let's see it in code!
JUnit and Groovy
Unit testing Java code in Groovy couldn't be easier, and there are many options for getting started. The most straightforward choice is to stick with the industry standard, JUnit. The simplicity and power of JUnit are unrivaled, its ubiquity as a helpful Java development tool is unparalleled, and there's nothing stopping the combination of JUnit and Groovy, so why reinvent the wheel? In fact, once you've seen JUnit and Groovy together in action, I'll bet you'll never turn back! The key thing to remember here is that you can do all the same things with JUnit in Groovy that you can do in the Java language; albeit with far fewer keystrokes.
