Using Scala Code For Safely Testing And Debugging Of Spring-based Java Apps

Specs2 Spring brings out codes that help J2ee developers to set up their context

for entire integration test and by context it is meant that the appropriate entries in JNDI environments as well as the beans under test, auto wired for test under execution. Specs2 Spring is easy to configure and thus is used for J2ee development. It is capable to run every example in its own transaction that rolls back on it owns during the completion of example.

During Java Development if Specs2 Spring is used for testing Java apps then it would be the most efficient and safe way to learn patterns of object-functional programming with Scala. It offers J2ee developers with benefits of Specs2 and they need not leave the Spring framework or rewrite perfect good code of Java during their J2ee development. The creator of Spec2 Spring offers three testing examples that will help in integration in forthcoming version of Specs2Springv1.0.

Java Development and offshore J2ee development entered into a new revolution with the inception of Spring framework. Being lightweight and sensible, it helps in simplifying the boilerplate code which makes Java programming tedious and time-consuming and makes offshore J2ee development more quicker for developers. All important details is abstracted by it from Java libraries in orders to make developers to use them in their programs. Thus by doing so it makes Java development a fun again and it entered at the right time when Java developers were just tired of the programs complexity.

Today Spring has become widely popular and is a gold standard for tools and frameworks that developers use. Its more of a reliable workhorse than an alternative. Spring is used by thousands of developers worldwide and millions of lines containing code are invested into Spring-based applications. We will learn Scala in this article. We will see the brief description of benefits that is offered by Scala while writing Spring components into it. Specs2 test framework and Specs2 Spring is an extension that can be used to write for Cake solutions where Scala code can be used for introducing into Spring-based Java applications. It allows J2ee developers to write tests in Scala so as to test the Spring code. Developers can take full benefits of all the features of Specs2 framework and apply them to the Spring test code. This article is intended for developers who are familiar with Spring framework.

Spring and Scala:There are many benefits of integrating Scala with Spring and they are quite familiar with Spring developers. Springs dependency injection model is rejected by Scala. In Scala instances of other objects are not injected into existing components but functionality is composed. With inheritance of composition Scala replaces Springs dependency injection. As it is a strong typed object-functional language it offers much more than just a different approach to dependency injection. Additionally Scala helps developers to construct rich type systems and thus leverage functional programming even while still continuing with object-oriented programming.

It lets you to express difficult or impossible concepts to be implemented in Java code which is an increasingly important benefit for developers who build highly concurrent applications.
