Written by way of major specialists within the box, this ebook exhibits you ways to leverage a collection of best-of-breed Open resource improvement instruments to take the ache out of J2EE and construct a whole Web-based software. you are going to mix those instruments to really decrease the issues of failure on your software, whereas expanding total process balance and robustness. besides the instruments brought right here, you are going to increase the PetSoar program, which follows the PetStore program utilized by solar Microsystems to illustrate positive aspects of J2EE. With PetSoar, the authors specialise in constructing a maintainable and versatile program, instead of showcasing the result, so you might practice the cloth on your personal tasks.

Sample text

Typically, throughout the lifetime of an application, the cost of maintenance outweighs the cost of initial delivery. On top of that, there’s the additional cost to the business of not being able to change functionality. Developing for maintainability has a higher return on investment in the long run. Clean and flexible designs, code quality, and testing all contribute to maintainability. Unfortunately, as the pressure to reduce time-to-market intensifies, these values are usually the first to be sacrificed to deliver more quickly.

A few of the IDEs go one step beyond that and provide a JUnit runner integrated into the development environment. That’s what integrated development environments are supposed to do, right? This prevents the need for having to switch between windows, which often slow because of garbage collection kicking in on window switches, and allows easy cross-referencing of test results with code. That is, you can click a test failure and jump to the line of code that caused it. 6 show examples of IDE integrations.

TestCase; public class TestCsvParser extends TestCase { public void testParseSimpleLine() { // ... get(1)); } } Now, running the test class again — exactly as before — runs both tests. JUnit automatically runs all methods starting with the name “test” in a class. This test passes the first time. The implementation of CsvParser was just too good. Now we can try testing a more awkward situation, such as what happens when one of the values in the CSV line is empty. TestCase; public class TestCsvParser extends TestCase { public void testParseSimpleLine() { // ...
