# `nest-slimcheck`

An `IsTest` implementation such that the `SlimCheck` framework can be

used with [`nest-core`](https://github.com/hargonix/nest-core).

The main contribution of this implementation is the `PropTest` type,

together with its `IsTest` implementation such that the `SlimCheck`

framework can be called from within `nest` test suites.

Here is a full example:

```lean

import NestCore

import NestSlimCheck

open Nest.Core

open Nest.SlimCheck

def tests : TestTree := [nest|

  group "examples"

    group "examples positive"

      test "rfl" : PropTest := .mk <| ∀ (x : Nat), x = x

      test "reverse_append" : PropTest := .mk <| ∀ (xs ys : List Nat), (xs ++ ys).reverse = ys.reverse ++ xs.reverse

    group "examples negative"

      test "lt" : PropTest := .mk <| ∀ (x y : Nat), x < y

      test "append_com" : PropTest := .mk <| ∀ (xs ys : List Nat), xs ++ ys = ys ++ xs

]

def main : IO UInt32 := Nest.Core.defaultMain tests

```

## Dependency footprint

Right now `SlimCheck` is within `mathlib4` which makes it necessary to

pull quite a large chunk of libraries in to compile this adapter, we

hope to extract `SlimCheck` either to `std4` or to its own library

in the future.
