Hey Allen,
I think you've got it backwards. You shouldn't be importing the
regular module from the test one, but hiding the test modules within
the regular one - behind a `#[cfg(test)]` directive.
To apply this to your example, in `myprogram.rs` you should have a line
#[cfg(test)]
mod testprogram;
and then in the test file, put `#[test]` above your individual tests.
Then you compile `myprogram.rs` and, when compiled with `--test`, it
compiles in the test code.
Another, arguably more common practice, is to write
#[cfg(test)]
mod tests {
use super::{foo, bar};
#[test]
fn test_foo_is_bar {
assert_eq!(foo(), bar());
}
}

Have fun learning Rust!
