Undefined reference to `pow' and `floor'
... an error, but pow, floor, and printf functions have undefined references, now if I will try to link this to executable:

Sorting object property by values
...ing exactly what you set out to do. That would work in all the browsers I know of, but it would be dependent on an implementation quirk, and could break at any time. You should never make assumptions about the order of elements in a JavaScript object.

When should I mock?
...er interface. Before we pass a mock MailServer, we "train" it, so that it knows what method calls to expect and what return values to return. At the end, the mock object asserts, that all expected methods were called as expected.
