camelCase != PascalCase

I came across the same issue, but one could argue that camel case by definition starts with a lower case letter.
I suggest to improve the description to be more precice about the imput the method receives.

Something like:
"Only valid camelCase strings will be passed into the method. No PascalCase or sentence are passed"

Otherwise a sentence like "PascalCase is not camelCase, says Chris" would also lead to incorrect results. IMHO.

Not a issue

I've modified the tests to be more clear. I've enhanced existing ones and I've added a few negative tests as well.

Thank you, useful feedback. I'll try and impliment your suggestions now.

Oops, I guess that's my fault, since the examples were my suggestion. But it seems that the example has been fixed, so maybe you'd mark the issue as resolved?

I'll add some examples to the description and add some tags.

Thanks for the feedback, I'm new with this kata creating thing.

Thanks! Hope that is fixed now.

Thanks for the feedback.
I think that, if your code was not able to pass the final submission, it was because of an error in your code.
In fact, nothing has changed here.
So, please, because you have already passed the kata, look at all the test cases in the 'official solution' and double check your solution. In case of further investigations are needed, post here your code (marking as having spoiler content).

Details added.
