The Real Cost of Change in Software Development

software-development-2-logo

There are two widely opposed (and often misunderstood) positions on how expensive it can be to change or fix software once it has been designed, coded, tested and implemented.

From Top to Bottom – TDD for Web Applications

software-development-2-logo

I am a “testing fanatic” but I don’t understand test-driven development. Or so I thought. I have read a few books and numerous blog posts about it, and all of them have one major problem: The examples are always too simple.

We can use the Spring org.springframework.core.io.Resource or org.springframework.core.io.ResourceLoader interface to find resources in our application.
