please either fix it or remove it from the Strings II badge list
The test suite should be working now. I fixed the parentheses problem mentioned in the other comments (it should now recognize left and right parentheses as different). There were also seven spaces between words in the test suite, though the encoded description indicated five—that has been fixed, as well.
I think this test suite is broken, Even if I return a copy of y_correct the assertion fails. Also the answer for test 2 is incorrect, the '(' is wrong both parens are the code for ')'. running the test code in my matlab the assertions do not fail.
You are correct that the test suite is messed up. I just submitted one with the correct Morse Code string for '(' [which failed], and one with the incorrect substitution [which passed].
Andrew Dobrovolc was right, the "(" is confused with ")".
