At least one of the sample tests should include some duplicate numbers as you say in the kata description there may be duplicates.

I don't understand why this kata's satisfaction is higher than 75%.

There are many flaws:

• There's no sample test cases (what you've put is useless and not relevant)
• When your test fails, the message doesn't help at all. You should, at least, give the user's result and the expected result
• I'm pretty sure I've already solved a very similar kata

Nice one.

However, it misses a sample test where the answer is xx.00.

Random tests feature uppercase and lowercase characters but the kata description doesn't warn about this.

Solved it with recursion!

As others said, there should be more sample test cases with special characters (thinking about the point in the really last test).

Wasn't very clear especially about tests. I agree with ben8p that the team mate part can be hard-coded.

There should be some test examples in the description.

You should add some random tests.

Way too basic. But giving a "Not much" opinion is not relevant. At least there aren't any issues or mistakes in it.

Kata is too basic.
You should add some constraints to make it harder:

• upcasing one word out of 2
• upcasing only words with at least 5 letters

Feel free to add your own constraints.

A very good kata for those who want to practice recursion (like I did, but I saw in the user solutions it wasn't the only method available).

If the random amounts don't have ".10", ".20", ... all of my tests work. But they don't if any of the amounts have these decimals...
