Note: This site is currently "Under construction". I'm migrating to a new version of my site building software. Lots of things are in a state of disrepair as a result (for example, footnote links aren't working). It's all part of the process of building in public. Most things should still be readable though.

Rust Pretty Assertions

Super helpful crate that shows color diffs in rust tests (including JSON outputs)

Usage

Code

Cargo.toml

[dev-dependencies]
pretty_assertions = "1.4"

Code

main.rs

fn main() {
  println!("Hello, Errors")
}


#[cfg(test)]
mod test {
    use pretty_assertions::{assert_eq, assert_ne};

    #[test]
    fn pretty_test() {
        assert_eq!(1, 2);
    }
}
