Please, read the instructions again, you're not understanding them, and check how the test you mention now is ok too

'codewars' is a merge from 'cdwr' and 'oeas':

    s:  c o d e w a r s   = codewars
part1:  c   d   w   r     = cdwr
part2:    o   e   a   s   = oeas

Test: codewars can't be created from code and wasr.

There the s is before the r in wasr and not in codewars, see?

The test is to check if the characters in part 1 and part 2 can add up to s. If what you are saying then the test: codewars can be created from cdwr and oeas should be wrong because the chacters aint in the same order. Yet this test passes.

The restriction is that the characters in part1 and part2 are in the same order as in s.

They're not in the same order, so, the tests are ok.

Language: Java
Test: codewars can't be created from code and wasr. Clearly codewars can be created from these.

Language? Proof?

There is a lot of mess in your tests. That is in java. Look into that
