testtools is used to collect boilerplate code that tends to show up when
writing tests. It should never be added as a regular dependency in a
project's Cargo.toml, but rather added as a dev-dependencies.
The functions/objects in this crate can have quirks that make them unsuitable for anything but their very specific purposes.
This crate may suffer from chronic underdocumentation. Use the source, Luke.
