caramelo

Caramelo (caramel in Portuguese) is a comprehensive, production-ready unit testing framework for Rust with a focus on simplicity and ease of use.

Features

Several useful matchers:

• logical: eq, ne, le, lt, ge and gt
• range: between
• array: item, len
• wildcard: any
• string: contains, starts-with, ends-with

Assertion traits

• is, is_eq, is_ne, is_lt, is_le, is_gt and is_ge

Quick Start

Add caramelo to your Cargo.toml:

caramelo = { version = "0.1.0-beta.1" }

Usage Example

Here's how simple it is to create unit tests with caramelo:

use caramelo::{expect, matchers::eq, assertions::Is};

/// Test equality matcher

#[test]
fn test_equal() {
    expect(1).to_be(eq(1));
}

#[test]
#[should_panic(expected = "Expected 1 to be equals to 2")]
fn test_not_equal() {
    expect(1).to_be(eq(2));
}

/// Test is assertion

#[test]
fn test_is() {
    "a".is("a");
}

#[test]
#[should_panic(expected = "Expected a to be equal to b")]
fn test_is_panic() {
    "a".is("b");
}
