ContinueJunit Code Coverage with Jacoco
Introduction In this post I will show you how to work with Junit code coverage with JaCoCo code coverage library, which is quite a new maven plug-in that provides the JaCoCo runtime agent to your tests and allows basic report creation. Currently it supports instruction, branch, line, method and class coverage which is pretty enough you can expect from this kind of tool. Additionally, it can measure and report cyclomatic complexity for methods and summarize the complexity for classes and packages.
ContinueHandling Default Exceptions in Mule
A catch exception strategy can be defined to customize the way Mule handles messages with errors. A catch exception strategy catches all exceptions thrown within its flow and processes them, thereby overriding Mule’s implicit default exception strategy. Mule’s catch exception strategy behavior is similar to a Java catch block, except that a new exception cannot be thrown or another exception cannot be caught within a catch exception strategy.

Junit provides an option of tracing exception thrown by a Java method. There are different ways of handling exceptions in JUnit tests. Standard Junit’s org.junit.Test annotation offers expected attribute that allows us specifying the a Throwable to cause a test method to succeed if an exception of the specified class is thrown by the method. A Java unit test should verify correct exception thrown in exceptional case and no exception should be thrown in normal case. For this to test exception thrown by a Java method using @Test(expected=””) we need…
ContinueException Handling Best Practices in Java
An exception is an event that occurs during the execution of a program that disrupts the normal flow of the program and the program terminates abnormally. Types of Exception – the exception can be either a checked exception or an unchecked exception.

It does so by declaring that exception in the throws clause of its declaration.
