paramtest

With paramtest, you can define multiple sets of input values for a single test function, and each set will be run as a separate test case.

Example

Here's how you can use paramtest in your tests:

use paramtest::paramtest;

#[paramtest(
    one=(1, 2),
    two=(2, 3),
    hundred=(100, 101),
)]
fn add_one(input: u64, output: u64) {
    assert_eq!(output, input + 1)
}

This is effectively the same as writing the following:

#[test]
fn add_one_one() {
    add_on(1, 2);
}

#[test]
fn add_one_two() {
    add_on(2, 3);
}

#[test]
fn add_one_hundred() {
    add_on(100, 101);
}

fn add_one(input: u64, output: u64) {
    assert_eq!(output, input + 1)
}

Each #[paramtest(...)] attribute defines named test cases with their own arguments. The macro will generate a separate test for each case, making your tests concise and easy to maintain.

Usage

1. Addparamtest crate as a dependency in your Cargo.toml.
2. Annotate your test functions with #[paramtest(...)] and provide named cases with argument tuples.
