The parameter order of assertEquals is wrong. The first parameter should be the expected one not the second parameter.

Duplicate ;-)

fix code style to java style instead of c (in java style curved brackets in same line as code block declaration)

add null checking case for tests (if null passed should return empty string)

remove oop tag from this kata because it is about simple string manipulations, not oop

@Blind4Basics: Yes, was just to get it work, nothing more - generally better to delete this one (but not my kata, not my decision);-)...

@smile67: is that really useful? Considering the satisfaction rate and the number of guy who already completed it and downvoted it, this kata will never go out of beta. :/

But it's nive to have it at least "working", yes.

cheers

fixed...

Not my kata, but issue fixed;-)...

This Kata is broken since more than a year. Either fix or delete.

test class don't work well

Add more test cases incl random test cases.

The test class should be public. the top import was wrong.

Provided test cases don't compile.

Test case syntax errors.
Missing closing braces in initial solution code.
