expectest

Work In Progress

Library provides functions for unit testing with human-readable syntax. Inspired by Nimble for Swift.

One of main purposes of this library is to show what data was used in a broken test. Consider this example: rust let result = ...; expect!(result).to(be_equal_to([1, 2, 3])); Assume that 'result' contains vec: [1, 2, 2]. Of course test fails and gives us a message: bash expected to be equal to <[1, 2, 3]>, got <[1, 2, 2]>

Note: You need to use cargo test -- --nocapture to see output from tests.

Usage

In Cargo.toml: toml [dev-dependencies] expectest = "*"

In your crate: ```rust

[cfg(test)]

[macro_use(expect)]

extern crate expectest; ```

You can export all needed functions and types from prelude module: rust use expectest::prelude::*;

Simple unit test: rust expect!(Some(6)).to(be_some());
