jMock - An Expressive Mock Object Library for Java - 3 views
-
JMock is a library that supports test-driven development1 of Java2 code with mock objects3. Mock objects help you design and test the interactions between the objects in your programs. -
"JMock is a library that supports test-driven development of Java code with mock objects. Mock objects help you design and test the interactions between the objects in your programs. The jMock library: makes it quick and easy to define mock objects, so you don't break the rhythm of programming. lets you precisely specify the interactions between your objects, reducing the brittleness of your tests. works well with the autocompletion and refactoring features of your IDE plugs into your favourite test framework is easy to extend."

Quick guide on class, instance and local variable in Java. major difference between all these three variable is there scope and how do you access it. class variable belongs to class, instance belongs to Object and local variable belongs to local code block.

-
A small toolkit of classes that support lock-free thread-safe programming on single variables. In essence, the classes in this package extend the notion of volatile values, fields, and array elements to those that also provide an atomic conditional update operation of the form: boolean compareandSet(expectedValue, updateValue);
-
Atomic classes are not general purpose replacements for java.lang.Integer and related classes. They do not define methods such as hashCode and compareTo. (Because atomic variables are expected to be mutated, they are poor choices for hash table keys.)
- ...4 more annotations...
-
The specifications of these methods enable implementations to employ efficient machine-level atomic instructions that are available on contemporary processors.

java.util.concurrent.atomic Class AtomicInteger java.lang.Object java.lang.Number java.util.concurrent.atomic.AtomicInteger
-
An int value that may be updated atomically. See the java.util.concurrent.atomic package specification for description of the properties of atomic variables. An AtomicInteger is used in applications such as atomically incremented counters, and cannot be used as a replacement for an Integer. However, this class does extend Number to allow uniform access by tools and utilities that deal with numerically-based classes.
-
int incrementAndGet() Atomically increments by one the current value.

JDBC 4.0 Enhancements in Java SE 6 - 0 views
-
In JDBC 4.0, we no longer need to explicitly load JDBC drivers using Class.forName(). When the method getConnection is called, the DriverManager will attempt to locate a suitable driver from among the JDBC drivers that were loaded at initialization and those loaded explicitly using the same class loader as the current application.

Auto-loading of JDBC driver class

JDBC 4.0 Enhancements in Java SE 6 Java Platform, Standard Edition (Java SE) version 6 (code name Mustang), is currently in its second beta release and is scheduled to be delivered in October of this year. Java SE 6 includes several enhancements to the Java Database Connectivity (JDBC) API. These enhancements will be released as JDBC version 4.0. The main objectives of the new JDBC features are to provide a simpler design and better developer experience. This article provides an overview of the JDBC 4.0 enhancements and what benefits they offer to enterprise Java developers. We will explore the new JDBC features with the help of a sample loan processing application using Apache Derby as the back-end database.

Page 2 - Java Developers Leery of IBM-Sun Merger - 0 views

IBM still runs basic physics last I checked and has deep resources in research to throw at any problem it wants

with more money and influence than nearly all of their competitors

both companies are highly invested in Java, which means it will continue, but in what form we have no idea

IBM is not interested in Sun software but in the Sun hardware and storage
-
-
pose a number of integration issues for IBM Software Group
-
expect that IBM will take the long view, that an open, flourishing ecosystem around Java will be the tide that lifts all boats
-
some observers say IBM would do well to merge the best parts of both platforms into one.
-
IBM has been a proponent of open standards in the Java ecosystem, and I expect that will continue
-
shed a lot of the weaker products (and a significant number of redundant staff)
-
-
conclusion: SUN and JCP suck, so they deserve this. God bless java and java dependent vendors.

Shrinkwrap provides a simple mechanism to assemble archives like JARs, WARs, and EARs with a friendly, fluent API. JavaArchive archive = ShrinkWrap.create(JavaArchive.class,"archive.jar") .addClasses(MyClass.class,MyOtherClass.class) .addResource("mystuff.properties"); From there you may deploy directly into any supported integration container like JBoss EmbeddedAS, GlassFish v3 Embedded, Jetty, or OpenEJB. Or perhaps you'd like to export the archive to a file or exploded directory structure. Maybe you'd prefer to serialize it over the network to a remote host. The possibilities are limitless. To boot, ShrinkWrap is the supported deployment mechanism of the Arquillian project, and together we render the testing of true enterprise components amiable as a puppy. Where Java EE brought a POJO programming model to application development, we've brought it to testing. You handle your business logic; we'll do the rest. To foster community participation, the majority of documentation and examples are available through our Wiki. Releases are available either via our Downloads section, or through the JBoss Maven Repository, which we recommend is configured in ${userHomeDir}/.m2/settings.xml:

jmockit - A capable and elegant developer mock testing toolkit for Java - Google Projec... - 0 views
-
"JMockit allows developers to write unit/integration tests without the testability issues typically found with other mocking APIs. Tests can easily be written that will mock final classes, static methods, constructors, and so on. There are no limitations. The JMockit mocking API is simple, consistent, and minimal. There are no special methods or annotations that need to be used in test code, apart from those that really make sense. In general, the use of JMockit APIs for mocking leads to test code that is better structured and more readable. "
