# rand_testsuite

A Testsuite for random number generators. It implements NIST 800-22.

It is intended to be more as a smoketest to ensure that random number generation isn’t completely broken.

## Crate Features

rand_testsuite defines the following features:

- `std`: Uses the `std` library’s maths routines instead of a freestanding pure-rust implementation.
- `rand_core`: Allows you to directly test `RngCore` trait implementations. Enables allocations.

## Getting Started

This is how you may use this crate to evaluate a random number generator (requires `rand_core`!)

```rust,ignore
let mut rng = rand::thread_rng();
assert!(CombinedRandomTest::default().evaluate_rng(&mut rng).unwrap_or_default() > 0.01);
```

### Installing

You can add this library to your crate with the following command:

```sh,ignore
cargo add rand_testsuite --dev
```

This makes the dependency available in testsuites.

## Running the tests

```sh,ignore
cargo test
nix flake check .
```
