Pragmatic Unit Testing in Java with JUnit, 3rd Edition

Coding Style

This book’s code exhibits my preferred programming style and formatting for Java, tempered also with a need to keep code listings brief. Many of you will be offended by my elimination of “safety braces” around single-line conditional blocks:

if (condition) doSomething();

• It gets rid of a line in the code listing.

• In most cases, the if body fits onto a single line, as demonstrated.

• I find it reads better as a singular concept.

• If you ever need a second statement in the conditional body, you’ll likely remember to add the safety braces.

• If you forget…that’s why you write unit tests.

If you’re unswayed, feel free to add braces. Try without, though—you might like it.
