El paquete GoogleTest de Rust

El paquete GoogleTest permite hacer test más legibles: 

use googletest::prelude::*;

#[googletest::test]

fn test_elements_are() {

    let value = vec!["foo", "bar", "baz"];

    expect_that!(value, elements_are!(eq("foo"), lt("xyz"), starts_with("b")));

}

Podemos agregar la dependencia con este comando : 

$ cargo add googletest

    Updating crates.io index

      Adding googletest v0.11.0 to dependencies.

             Features:

             - anyhow

             - proptest

    Updating crates.io index

Y si corremos el test, tendremos este resultado: 

   Compiling hello_cargo v0.1.0 (/home/emanuel/Projects/rust/hello_cargo)

    Finished test [unoptimized + debuginfo] target(s) in 6.29s

     Running unittests src/main.rs (target/debug/deps/hello_cargo-4557c2a679e4325f)
