Use hamcrest

[leonardofl]

There is no problem in the line

assertTrue(actualStringSplits.containsAll(Arrays.asList(expectedStringSplit1, expectedStringSplit2)));

But I believe you would enjoy to learn how to use Hamcrest and write something like:

assertThat(actualStringSplits, containsAll(Arrays.asList(expectedStringSplit1, expectedStringSplit2)));

Advantage: when the test fails, the message is much more descriptive about what went wrong.
