Pragmatic Unit Testing in Java With JUnit
Learn how to improve your Java coding skills using unit
testing. Despite it's name, unit testing is really a coding
technique, not a testing technique. Unit testing is done by
programmers, for programmers. It's primarily for our
benefit: we get improved confidence in our code, better
ability to make deadlines, less time spent
in the debugger,
and less time beating on the code to make it work correctly.
This book shows how to write tests, but more importantly, it
goes where other books fear to tread and gives you concrete
advice and examples of what to test--the common things that
go wrong in all of our programs. Discover the tricky hiding
places where bugs breed, and how to catch them using the
freely available JUnit framework. It's easy to learn how to
think of all the things in your code that are likely to
break. We'll show you how with helpful mnemonics, summarized
in a handy tip sheet (also available from our
www.pragmaticprogrammer.com website) to help you remember
all this stuff.
With this book you will:
Write better code, and take less time to write it
Discover the tricky places where bugs breed
Learn how to think of all the things that could go wrong
Test individual pieces of code without having to include the
whole project
Test effectively with the whole team
We'll also cover how to use Mock Objects for testing, how to
write high quality test code, and how to use unit testing to
improve your design skills. We'll show you frequent
"gotchas"--along with the fixes--to save you time when
problems come up. We'll show you how with helpful mnemonics,
summarized in a handy tip sheet (also available from our
www.pragmaticprogrammer.com
website).
But the best part is that you don't need a sweeping mandate
to change your whole team or your whole company. You don't
need to adopt Extreme Programming or Test-Driven
Development, or change your development process in order to
reap the proven benefits of unit testing. You can start
unit testing, the pragmatic way, right away.
