Installation

There are 3 preferred ways to install specs2:

SBT

First you need to install sbt itself then you need to add the following dependency:

libraryDependencies += "org.specs2" %% "specs2-core" % "4.12.0" % "test"

scalacOptions in Test ++= Seq("-Yrangepos")

See here to learn more about sbt dependencies.

Maven

You can install Maven from there. Once installed, you need to create a pom.xml file with the maven-scala-plugin. In the pom.xml file you can add the following dependency:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  ...
<dependencies>
  <dependency>
    <groupId>org.specs2</groupId>
    <artifactId>specs2-core_2.12</artifactId>
    <version>4.12.0</version>
    <scope>test</scope>
  </dependency>
</dependencies>
  ...
</project>

Gradle

Go to this page to install Gradle. You then need to install the Scala plugin and add the following to your build.gradle file:

repositories {
  maven {
     url "https://oss.sonatype.org/content/repositories/releases"
  }
}

dependencies {
  testCompile "org.specs2:specs2-core_2.12:4.12.0"
}

Other dependencies

Depending on the specs2 features you want to use you will need to add more dependencies to your build:

Name	Functionality
`specs2-matcher-extra`	for the optional specs2 matchers
`specs2-cats`	for the cats matchers (only for `cats < 0.8.x`)
`specs2-scalaz`	for the scalaz matchers (`TaskMatcher` for example)
`specs2-scalacheck`	to use ScalaCheck properties in specifications
`specs2-mock`	to use Mockito matchers
`specs2-analysis`	to use the package dependencies matcher
`specs2-gwt`	to write given/when/then specifications
`specs2-html`	to export specifications as html
`specs2-form`	to create html form-like specifications
`specs2-junit`	to run specifications as JUnit tests

Note: the specs2-core jar depends on 2 other specs2 jars:

Name	Functionality
`specs2-common`	utility classes for text, collections, xml,…
`specs2-matcher`	common specs2 matchers. They can be used as a stand-alone library with JUnit
