Our company is moving from waterfall to scrum. 

So now testers and developers are really working together.
And there is an idea to use checklists and test-cases created by testers as stuff that will help programmers to develop software.

I really feel that something is wrong about it. E.g.: developers might misinterpret requirements documented by testers in test cases. Is there any disadvantages?

**UPDATE:** after 9 month of scrum I can say that developers actually have no time to double check info (from documentation and from test-case). So I can not even say whether it has bad or good influence on product quality. Actually definitly not bad, as it would be noticed.
