Today, I bump into a problem when fixing some failed unit test.
Long story short, I need to compare returned multiline string from class A and for some reason it randomly added a whitespace in each line end. This caused the unit test failed.
Solution
Found this solution which stripe out the line end whitespace using regrex.

private final Pattern LINE_END_SPACES = Pattern.compile(" +\$", Pattern.MULTILINE);
public String stripLineEndSpaces(String str) {
return LINE_END_SPACES.matcher(str).replaceAll("");
}
@Test
public void testAbc()
String testObject = "123 \n abc ";
assertEquals("123\n abc", stripLineEndSpaces(testObject));
}
