Add exec tests and cfg(test) compiler guards

Some tests throughout the codebase were just functions marked with the
`#[test]` macro. It is convention to have these test functions in a
`test` module with a compiler guard `cfg(test)`. This PR updates the
tests that aren't already setup like this to be in the `test` module.

Additionally, this PR also adds tests to the `exec` module to check the
remaining `Token` enum variations.
