[FLOW3-general] No Dependency injection in Tests?

[Jacob Floyd]

A unit test tests a small section of code (like a single function, or a 
particular use of a single function).
A functional test tests a feature including all of the functions, and 
dependencies required to make that feature work.

When you are using an object that is injected, you have to replace it with 
a mock object when testing. That way, you are not testing the injected 
object; you are only testing the particular use of a particular function 
(testing a single unit).

For example. Say you have some code that uses FLOW3's new HTTP stuff. You 
create a fake/mock http request (or response) handler that is injected in 
place of the full-blown http handler. Then it pretends to do http stuff 
whenever you are testing something else, without actually using the http 
code. That way you're only testing a single unit: a single section of code.
