TestAPI with core-builtins code

[bulent2k2]

"To get access to builtins in a test, the best way is to probably build up a stub code execution context."

We would like to provide a basic test that uses builtins (assuming no such test already exists.) So that we could test many commands that depend on builtins. e.g. epochTime.

At the moment, calling any such command results in a runtime error (compiler is not able to catch this problem):

Will be a good thing to have.
