This crate tests itself by seeing the difference between actual output to standard output and expected bytes. Previously, the built-in `assert_eq` does not show the difference between the left/right values by showing what characters are different from the other side. So, it was difficult for developers to figure out why tests fail. From this motivation, I want to introduce `pretty_assertions`, which provides `assert_eq` with more colorful diffs. See the following repository for more details about `pretty_assertions`. https://github.com/rust-pretty-assertions/rust-pretty-assertions
