On this day in 1944–as if the world didn't have enough troubles already—Mount Vesuvius decided to erupt, killing a bunch of villagers. Which just goes to show that you never really know what's gurgling under the surface, building up pressure and steam, ready to blow any second and rain destruction. A lot of code out there might fit that same description.

Don't wait for your own Vesuvian explosion of festering bugs. Start unit testing, or get better at unit testing, or get everyone unit testing, today with Pragmatic Unit Testing in Java 8 with JUnit, now in print and shipping from pragprog.com/book/utj2.

Pragmatic Unit Testing in Java 8 with JUnit

Pragmatic Unit Testing in Java 8 with JUnit steps you through all the important unit testing topics. If you've never written a unit test, you'll see screen shots from Eclipse, IntelliJ IDEA, and NetBeans that will help you get past the hard part—getting set up and started.

Once past the basics, you'll learn why you want to write unit tests and how to effectively use JUnit. But the meaty part of the book is its collected unit testing wisdom from people who've been there, done that on production systems for at least 15 years: veteran author and developer Jeff Langr, building on the wisdom of Pragmatic Programmers Andy Hunt and Dave Thomas. You'll learn:

• How to craft your unit tests to minimize your effort in maintaining them.
• How to use unit tests to help keep your system clean.
• How to test the tough stuff.
• Memorable mnemonics to help you remember what's important when writing unit tests.
• How to help your team reap and sustain the benefits of unit testing.

You won't just learn about unit testing in theory—you'll work through numerous code examples. When it comes to programming, hands-on is the only way to learn!
