Getting Started

SBT Binary Dependency

In your build.sbt, add the following libraryDependencies.

val hedgehogVersion = "0.9.0"

libraryDependencies ++= Seq(
"qa.hedgehog" %% "hedgehog-core" % hedgehogVersion,
"qa.hedgehog" %% "hedgehog-runner" % hedgehogVersion,
"qa.hedgehog" %% "hedgehog-sbt" % hedgehogVersion
).map(_ % Test)

Supported Scala Versions: 2.11, 2.12, 2.13 and 3

SBT Source Dependency

This project can be added as an SBT subproject.

// This can also be a branch name, like 'master'`, if you want to live on the edge
val hedgehogVersion = "${COMMIT}"
val hedgehogUri = uri("https://github.com/hedgehogqa/scala-hedgehog.git#" + hedgehogVersion)

lazy val root =
(project in file("."))
.dependsOn(ProjectRef(hedgehogUri, "core"))
.dependsOn(ProjectRef(hedgehogUri, "runner"))
.dependsOn(ProjectRef(hedgehogUri, "sbt-test"))

NOTE: Depending on your scala version(s) SBT might not resolve.

SBT Testing

Scala Hedgehog comes with a very primitive runner interface, and supports the SBT testing extension.

testFrameworks += TestFramework("hedgehog.sbt.Framework")

IntelliJ

The IntelliJ scala plugin only has hard-coded support for the most popular test frameworks. While Hedgehog is obviously not included in that list, an may never be, by extending the runner Properties tests can be run as an application (as Properties includes a handy main function). NOTE: This requires the test to be an object and not a class.

Example

See the examples module for working versions.

import hedgehog._
import hedgehog.runner._

object PropertyTest extends Properties {

def tests: List[Test] =
List(
property("reverse", testReverse)
)

def testReverse: Property =
for {
xs <- Gen.alpha.list(Range.linear(0, 100)).forAll
} yield xs.reverse.reverse ==== xs
}
