Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

The test cases should tell what values they expect instead of just simply stating "
[format]to[format]failed"The description should say what entries we may receive (in other words: define what 'convert to integer makes no sense' means; how am I supposed to guess in advance how to handle a single array with a single number? and what if two numbers or more ?, etc.). One needs to guess uncertainly from test cases.
Needs random tests.
assertEquals should be used.
