[Change Log](CHANGELOG.md)

## Synopsis

Gopter tries to bring the goodness of [ScalaCheck](https://www.scalacheck.org/) (and implicitly, the goodness of [QuickCheck](http://hackage.haskell.org/package/QuickCheck)) to Go.

It can also be seen as a more sophisticated version of the testing/quick package.

Main differences to ScalaCheck:

* It is Go ... duh

* ... nevertheless: Do not expect the same typesafety and elegance as in ScalaCheck.

* For simplicity [Shrink](https://javadoc.io/doc/org.scalacheck/scalacheck_2.11/1.14.1/index.html#org.scalacheck.Shrink) has become part of the generators. They can still be easily changed if necessary.

* There is no [Pretty](https://javadoc.io/doc/org.scalacheck/scalacheck_2.11/1.14.1/index.html#org.scalacheck.util.Pretty) ... so far gopter feels quite comfortable being ugly.

* A generator for regex matches

* No parallel commands ... yet?

Main differences to the testing/quick package:

* Much tighter control over generators

* Shrinkers, i.e. automatically find the minimum value falsifying a property

* A generator for regex matches (already mentioned that ... but it's cool)

* Support for stateful tests
