Overview

This is a macro for writing Rust test code in an easy way.

Getting Started

Crate has to be added as a dev-dependency to Cargo.toml.

[dev-dependencies]
test-macro = "0.1.9"

Example Usage

Consider testing the add function shown below.

fn add(x: i32, y: i32) -> i32 {
    x + y
}

In this case, if you want to write the test code in the tests directory, you can write it as follows.

// Need to import add function.
test_macro::test_assert_eq!(test_case_name, add(1, 2) => 3);

If you want to write it outside the tests directory, you can write it as follows.

#[cfg(test)]
mod tests {
    use test_macro::*;
    test_assert_eq!(test_case_name, add(1, 2) => 3);
}

This difference comes from importing the test-macro crate as a dev-dependencies crate.

No runtime deps
