-
-For the sake of brevity let's assume the following: within the context of
-single-process (_not_ the same as single-threaded), non-graphical programs the
-following may be said:
-
-1. A program may be thought of as a black-box with certain input and output
-   methods. It is the programmer's task to construct a program such that
-   specific inputs yield specific desired outputs.
-
-2. A program is not complete without sufficient testing to prove it's complete.
-
-3. Global state and global impure functions makes testing more difficult. This
-   can include singletons and system calls.
