Question

Does there exist a site which hosts collections of unit tests in various fields? specifically, instead of digging and extracting the packages that seem close to your subject of coding, I'd like to use it like shared code, see how it was tested. (and then also know how it should work)

So is there one like that? doesn't matter which programming language they're written in.

Answer 1

You can find lots of test code with Google code search. Search for "test" or the namespace/package names of popular test frameworks ("org.junit", for example)
