White spaces (special chars) in JUnit tests

[Krzysztof1985]

Hello!

I read a book and discover many errors in JUnit tests.
I think you should add some caption about white spaces.
For Example:
JUnit test from submodule
stereo-autoconfig
failed.
(CDPlayerTest)
But when I trimm the string as expected and as result works fine.
Could you fix this issue.

Kind regards
Krzysztof

Hi, Krzysztof1985.
I realized that instead of "\n" platform depended line separator should be used call which returns platform's line separator - System.lineSeparator() - since 1.7.

For example in https://github.com/habuma/SpringInActionExamples/blob/master/Chapter_02/stereo-autoconfig/src/test/java/soundsystem/CDPlayerTest.java:

assertEquals(
        "Playing Sgt. Pepper's Lonely Hearts Club Band by The Beatles" + System.lineSeparator(), 
        log.getLog());
