VisitGopter vs PropCheck
What both publish
| Fact | Gopter | PropCheck |
|---|---|---|
| Generators | It provides tighter control over generators than Go's testing/quick package. | It includes generators for common Ruby data types and a DSL for defining custom generators. |
| License | The repository identifies Gopter as MIT licensed. | The project is released under the MIT License. |
| Purpose | Gopter is a Go property-testing library that brings ideas from ScalaCheck and QuickCheck to Go. | PropCheck is a Ruby library for property-based testing that checks assertions against generated inputs. |
| Shrinking | Its shrinkers automatically seek a minimum value that falsifies a property. | When a generated case fails, PropCheck attempts to simplify it to a minimal counterexample. |
| Stateful testing | Gopter supports stateful tests. | The README lists stateful property testing as a possible future separate add-on library. |
